Server Quality Checklist

50%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v0.1.10

  • Disambiguation2/5

    With 813 tools spanning dozens of unrelated services, it's very difficult for an agent to distinguish which tool to use. Many tools have similar names (e.g., multiple 'send_email' variants) and several 'action' tools bundle disparate operations, causing ambiguity.

    Naming Consistency2/5

    Tool names follow no consistent pattern. Some use service_action (e.g., bluesky_action), others use service_specific (e.g., abn_lookup), and there is a mix of verb_noun and noun_verb styles. Generic names like get_run and list_runs add to the inconsistency.

    Tool Count1/5

    813 tools is excessive for any server. While the server attempts to be a universal toolkit, the sheer number makes it unwieldy for agents to navigate and for users to understand its scope. A well-scoped server typically has 3-15 tools.

    Completeness2/5

    The server is broad but shallow. Many services have only one or two tools, leaving obvious gaps (e.g., abn_lookup has no update/delete). Core workflows for many integrated services are incomplete, leading to potential agent failures.

  • Average 2.9/5 across 744 of 813 tools scored. Lowest: 1.5/5.

    See the Tool Scores section below for per-tool breakdowns.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the burden of behavioral disclosure. It merely says 'list', implying a read-only operation, but omits any details about side effects, rate limits, data volume, or return format.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise but at the expense of being under-specified. It fails to provide essential information, making it ineffective for an AI agent to correctly select and invoke the tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 10 parameters, no output schema, and no sibling differentiation, the description is woefully incomplete. It lacks any context that would help an agent understand its capabilities or constraints.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage and 10 parameters, the description adds no meaning to any input schema field. It does not explain the role of required fields (store_url, consumer_key, consumer_secret) or optional filters like per_page, page, search, email, role, orderby, and order.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose1/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List WooCommerce customers' is a tautology, essentially restating the tool name without providing any specific verb+resource differentiation. It fails to distinguish from sibling tools like woo_orders or woo_products.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines1/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is given on when to use this tool over alternatives. There is no mention of authentication prerequisites, pagination, or any context for usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description fails to disclose any behavioral traits, such as whether the tool is read-only, involves an API call, or has side effects. The description is too minimal to aid the agent in understanding execution implications.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, achieving conciseness, but at the cost of being under-specific. It lacks substantive content that would earn its place, as it provides minimal informational value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has three parameters, no output schema, and no annotations, the description is severely insufficient. An agent would not understand the tool's behavior, expected output, or how to set parameters appropriately.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage, and the tool description does not explain the 'type', 'min', or 'max' parameters. The description adds zero value beyond the parameter names, leaving the agent with no guidance on how to use them correctly.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose2/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get a random number fact' is vague and ambiguous. It does not clarify whether it returns a random number with a fact or a random fact about numbers. Among siblings like 'number_fact', the distinction is unclear.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines1/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as 'number_fact'. There is no mention of contexts, prerequisites, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description states 'Search' implying read-only, but no annotations exist. It fails to disclose that an api_key parameter is required for authentication, which is critical for usage. No rate limits, side effects, or other behavioral traits are mentioned.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but severely under-specified. It does not front-load essential information and fails to earn its place by providing value beyond the name.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 7 parameters, no output schema, and no annotations, the description is grossly incomplete. It offers no context for expected inputs, outputs, or usage scenarios, leaving the agent with minimal information.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description adds no meaning to the 7 parameters. It does not explain what 'keyword', 'city', 'countryCode', etc., represent, leaving the agent without guidance for correct invocation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose2/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search for events on Ticketmaster' is almost a tautology, restating the tool name without adding specificity. It does not differentiate from sibling tools like seatgeek_search_events or tm_search_attractions, and fails to convey the scope of search parameters.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, nor any conditions or exclusions. The description lacks any context for appropriate usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations and the description does not disclose any behavioral traits such as randomness quality (cryptographic vs pseudo), default charset, or side effects. The agent has no insight beyond the name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (4 words), which is efficient but too sparse. It lacks structure and reads as a tautology, missing the opportunity to provide meaningful context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations, no output schema, and no parameter descriptions, the description is inadequate. It fails to provide the agent with sufficient information to use the tool correctly or understand its behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the description does not explain the parameters. The meaning of 'length' and 'charset' is not conveyed beyond their names, so no value added over the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Generate a random string' is a clear verb+resource pair, but it does not differentiate from sibling tools like random_uuid or random_lorem_ipsum, which also generate strings. The lack of detail on the nature of the random string (alphanumeric? printable?) reduces clarity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines1/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No description of when to use this tool versus alternatives. With many random generation siblings, the agent needs guidance on which tool to pick. The description provides none.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but only says 'search.' It fails to disclose that the tool requires authentication, has rate limits, or what the response contains. Essential behavioral context is missing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The single-sentence description is brief but under-specified. Conciseness is undermined by the lack of critical information; it is not efficiently front-loaded with key details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (7 parameters, including required credentials) and lack of output schema, the description is severely incomplete. An agent cannot reliably invoke this tool without additional information about parameters and authentication.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the 7 parameters. It does not explain the purpose of searchIndex, itemCount, or credential fields, leaving the agent without guidance on parameter usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search for products on Amazon' clearly states the verb and resource, but it does not differentiate from sibling tools like amazon_browse or amazon_product, nor does it specify the search modality beyond keywords.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., amazon_browse, amazon_product). There is no mention of prerequisites such as API credentials (access_key, secret_key, partner_tag).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description must disclose behavior. It does not mention authentication requirements despite 'email' and 'password' parameters. No indication of read-only status or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely brief (5 words), but it omits critical information. Conciseness without substance is not helpful.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 5 parameters, no output schema, and no annotations, the description is severely incomplete. The agent cannot use this tool correctly without external knowledge.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema descriptions are absent (0% coverage). The description adds no meaning to parameters like 'folder', 'limit', 'email', 'password'. The agent cannot infer their purpose or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose2/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search emails in an inbox' is vague. It does not specify the scope of search (e.g., subject, body, sender) or the return format (list of summaries vs full emails). It fails to differentiate from sibling 'email_read_inbox'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like 'email_read_inbox'. No context on prerequisites or best practices.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description must disclose behavioral traits. It does not mention whether actions are destructive, authentication requirements (though api_key parameter hints), rate limits, or return behavior. This is a critical gap for a tool with multiple actions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely short (one sentence), which is concise but at the expense of essential information. It is not well-structured; it simply lists actions. Overly brief descriptions that omit critical details are not considered effective conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 6 parameters, no schema descriptions, no annotations, and no output schema, the description is severely incomplete. It fails to provide context on how the tool works, parameter relationships, or expected results, making it nearly unusable without external knowledge.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Input schema has 0% description coverage, and the description adds almost no parameter meaning. It indirectly lists possible action values but does not explain api_key, stream_id, query, count, entry_ids. The agent cannot understand how to use parameters from the description.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states it performs Feedly actions and lists five specific actions, giving some clarity. However, it does not explain the overall purpose or what Feedly is, and the verb 'Perform' is vague. It is minimally adequate to distinguish from sibling tools, but lacks specificity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention any prerequisites, context, or exclusions. The agent is left to infer, which is insufficient.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits such as read-only nature, rate limits, authentication requirements, or typical response structure. This is a significant gap for a data-retrieval tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    At 4 words, the description is extremely concise but lacks necessary details. Conciseness should not come at the cost of completeness; this is under-specified.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 2 parameters, no output schema, and no annotations, the description is severely incomplete. It fails to explain the tool's output, parameter usage, or how it fits among similar artist tools.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description should compensate by explaining parameters. It does not mention 'artist' or 'api_key' at all, leaving their purpose and constraints undocumented beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get Last.fm artist info.' conveys a clear verb-resource pair but is vague about what specific info is returned. It does not differentiate from sibling tools like lastfm_search_artists or lastfm_similar_artists, which also deal with artists.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description offers no guidance on when to use this tool versus alternatives. No mention of context, prerequisites, or exclusions, leaving the agent to guess.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description fails to disclose any behavioral traits such as return format, pagination, rate limits, or whether this fetches payments received or made. The burden falls entirely on the description, which provides zero behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    While extremely concise, the description is under-specified. It sacrifices necessary information for brevity, leaving the agent with insufficient context to use the tool effectively.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of five parameters with no descriptions, no output schema, and many sibling tools, the description is utterly inadequate. It fails to provide essential details about filtering, response structure, or tool differentiation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description should explain the parameters, but it offers nothing beyond their names. The agent cannot determine valid status values, date formats, or how access_token and tenant_id are used.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get payments from Xero' clearly indicates the verb and resource, but it does not distinguish from sibling tools like xero_invoices or xero_bank_transactions, and does not clarify what constitutes a payment in Xero context.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, nor any prerequisites or exclusions. The agent must infer from the parameter names alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. The description does not disclose any behavioral traits such as authentication requirements, rate limits, pagination, or what happens with no results. For a search tool, this is a significant gap.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, which is concise but sacrifices informativeness. It could be expanded to cover key details without being verbose. It is not structured with front-loaded key information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (7 parameters, no output schema, no annotations), the description is severely lacking. It does not explain return values, pagination, how to filter, or prerequisites. Extremely incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning beyond the input schema. The schema has 7 parameters with types but no descriptions, and the description provides no clues about parameter roles, required combinations, or format (e.g., location vs lat/lng). Schema coverage is 0%.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search' and resource 'businesses on Yelp', but lacks specifics on what makes it distinct from sibling tools like yelp_get_business or yelp_search_events. It is adequate but generic.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines1/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. No mention of typical use cases, exclusions, or when to prefer other Yelp tools like yelp_autocomplete or yelp_get_reviews.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden. It only says 'Read Telegram messages/updates,' which implies a non-destructive operation but lacks details on authentication requirements, behavior when no messages are available, rate limits, or other critical behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise (one sentence) but fails to convey essential information. While brevity is positive, the sentence does not earn its place because it lacks detail needed for correct tool usage.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 3 parameters (1 required), no output schema, and no annotations, the description is severely incomplete. It does not describe the return format, parameter semantics, or usage behavior, making it inadequate for an AI agent to use correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning the schema has no descriptions. The tool description does not compensate by explaining the three parameters (bot_token, offset, limit). Only bot_token can be inferred from context, but offset and limit are left completely unexplained.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description states the tool reads Telegram messages/updates, clearly indicating the verb and resource. However, it does not distinguish this tool from sibling tools like telegram_get_updates, which likely has overlapping functionality.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., telegram_get_updates, telegram_search). No context about prerequisites or best practices.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits such as read-only nature, authentication requirements, or rate limits. The description adds no value beyond a basic label.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (one sentence), but it is underspecified and fails to convey essential information. Conciseness without informativeness is not effective.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations, no output schema, and three undocumented parameters, the description is completely inadequate. It does not help the agent understand the tool's inputs, outputs, or behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the parameters start_date, end_date, or api_key. The description is too minimal to compensate for the lack of schema documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get Toggl time entries' provides a verb and resource, indicating a read operation. However, it lacks specificity about what time entries (all, by user, filtered) and does not differentiate from sibling tools like toggl_summary, which may also retrieve time data.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is given on when to use this tool versus alternatives. With a large sibling list including toggl_create_time_entry, toggl_projects, and toggl_summary, the description offers no context for choosing this tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose side effects, rate limits, or authentication details beyond the presence of an api_key parameter. The tool's behavior is opaque.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but severely under-specified. It lacks essential details, making it insufficient for an agent to use correctly.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Without output schema, annotations, or parameter descriptions, the tool is incomplete. The agent cannot know the return format or how to provide required inputs properly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description adds no information about the three parameters (source, target, api_key). The agent must infer their meaning and format (e.g., currency codes, key source) without any guidance.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Get exchange rates from Wise,' which specifies a verb and resource. However, it does not clarify whether these are latest rates, historical rates, or require specific currencies. It fails to differentiate from similar exchange rate tools in the sibling list.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool over alternatives like exchangerate_* or forex_* tools. No mention of prerequisites, such as needing an API key or specific currency codes.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden for behavioral disclosure. It only says 'Search LEGO sets,' with no mention of authentication requirements (api_key is a param but not clarified), pagination, rate limits, or return format. This is a critical gap.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely brief (one sentence), but this brevity sacrifices necessary detail. It is under-specified rather than concise, lacking key operational context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 5 parameters, no output schema, and no annotations, the description is far from complete. It fails to provide essential details like parameter purposes, authentication, or expected results, making the tool difficult to use correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no explanation for any of the 5 parameters. The agent has no information on what `query`, `year`, `theme`, `pageSize`, or `api_key` mean or how to use them effectively.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Search LEGO sets via Brickset API,' clearly specifying the verb (search) and resource (LEGO sets). However, it does not differentiate from the sibling tool `brickset_get_set`, which likely retrieves a single set. The clarity is good but lacks distinctiveness.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like `brickset_get_set`. The description does not mention prerequisites, contexts, or exclusions, leaving the agent without direction on selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must fully disclose behavioral traits. It only lists action names but does not indicate which actions are read-only (e.g., get_time_entries) vs. write (e.g., create_time_entry), nor does it mention authentication needs, rate limits, or error behavior. The agent lacks critical context to infer side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, making it concise, but it merely lists actions without structure or hierarchy. It could be improved by grouping actions by type (read vs. write) or providing a brief example. The shortness does not compensate for lack of useful content.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 7 parameters and no output schema, the description is woefully incomplete. It does not describe what each action returns, how to construct a valid request, or what the expected behavior is for different parameter combinations. For a multi-action dispatcher, this level of detail is insufficient for an AI agent to use correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning no parameter descriptions exist in the schema, and the description adds no meaning. It does not explain what each parameter (e.g., api_key, workspace_id, start, end) does or how they map to the listed actions. The agent cannot determine which parameters are required for each action.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Perform a Clockify action' and lists possible actions, indicating it is a generic dispatcher for Clockify operations. However, it lacks specificity about what each action does and why a user would invoke this tool overall. Compared to sibling 'action' tools like github_action, it follows a similar pattern but does not clearly distinguish its purpose.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description simply enumerates available actions without explaining context, such as 'Use this when you need to interact with Clockify time tracking.' There is no mention of when not to use it or which sibling tools serve overlapping purposes.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description must disclose behavior. It implies a read operation but does not specify the nature of the data (real-time/historical), return format, authentication requirements, or rate limits. The presence of an 'api_key' parameter is not explained, leaving the agent unsure about mandatory input.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no fluff, making it concise. However, it is too brief to convey essential information, leaning toward under-specification rather than efficient conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given zero annotations, no output schema, and four undocumented parameters, the description fails to provide enough context for the agent to effectively use the tool. Critical aspects like parameter semantics, required authentication, and expected response are missing, leading to low completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, but the description adds no meaning to the four parameters (symbol, id, convert, api_key). It does not explain their roles, required formats, or whether they are optional. The agent must rely solely on parameter names, which is insufficient for correct invocation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states the tool gets 'cryptocurrency quotes from CoinMarketCap,' which is a specific verb and resource. However, it lacks differentiation from sibling cmc_* tools like cmc_global_metrics, cmc_info, cmc_listings, and cmc_trending, as it doesn't clarify what 'quotes' entails (e.g., price, volume, market cap). It is clear but not distinctive.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of context, exclusions, or prerequisites (e.g., requiring an API key). Among many crypto-related siblings, the agent has no basis for choosing this tool over others.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full responsibility for behavioral disclosure. It fails to mention any traits such as pagination (despite a 'limit' parameter), authentication requirements, rate limits, or output format. The description is essentially a bare statement of purpose.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely short (one sentence), which is concise but at the expense of necessary detail. It does not earn its place by providing value beyond the name; it essentially repeats the tool's name.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the minimal schema, no annotations, and no output schema, the description is critically incomplete. It fails to specify return values, sorting, or any contextual detail that would help an agent use the tool effectively. A search tool requires more context about results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% (no descriptions for 'q' or 'limit'). The tool description does not explain what these parameters represent or how to use them, leaving the agent without guidance beyond the schema keys and types.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Search') and resource ('Deezer playlists'), making basic purpose unambiguous. However, it does not differentiate from the sibling tool 'deezer_search', which also performs searches but likely across all entities, missing an opportunity to clarify scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like 'deezer_search' or other Deezer tools. The description offers no context for selection, leaving the agent to infer usage solely from the name.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits such as authentication requirements (despite the api_key parameter), rate limits, or what happens when the search returns no results. The agent has no insight into the tool's behavior beyond the fact that it searches.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, which is concise but severely under-informative. It does not earn its place because it repeats the name of the tool without adding value. An effective description would provide context beyond the name.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters with no schema descriptions, no output schema, and no annotations, the description is grossly incomplete. It fails to provide any guidance on usage, parameter semantics, or expected behavior, leaving the agent with significant ambiguity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% (no parameter descriptions), and the description does not explain any of the four parameters (q, location_address, start_date_range_start, api_key). The agent receives no guidance on required format, optionality, or meaning of each parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search for events on Eventbrite' clearly states the verb (search) and resource (events on Eventbrite). It distinguishes the tool from siblings like eventbrite_get_event (single event retrieval) and eventbrite_create_event (creation). However, it lacks specificity about the search criteria (keyword, location, date) which are evident from the schema but not mentioned.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. Sibling tools like eventbrite_get_event or eventbrite_get_attendees have different purposes, but the description does not indicate the appropriate context for searching versus retrieving specific events or attendee lists.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description lacks any behavioral details such as whether it lists all tags, supports filtering, or requires authentication. With no annotations, the description fails to disclose basic traits like read-only nature or API key usage.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    At one sentence, it is brief but ineffective as it omits crucial information; conciseness should not come at the cost of utility.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is severely incomplete for a data retrieval tool with two parameters and no output schema; it fails to specify what tags are, the response format, or how to use the parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has zero description coverage, and the description does not explain what the 'q' and 'api_key' parameters represent or how they affect the results.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get Guardian tags' clearly indicates the tool returns tags from The Guardian, distinguishing it from sibling tools like guardian_get_article, guardian_get_edition, guardian_get_sections, and guardian_search_articles.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives; there is no information about context, prerequisites, or situations where tags are more appropriate than sections or search.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description does not disclose any behavioral traits beyond the bare action. It does not mention that the tool is read-only, requires an API key (though schema has api_key param), has rate limits, or what the output format is. With no annotations, the description carries full burden but fails to provide useful context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but under-specified. It does not earn its place as it provides no useful information beyond the tool name. A longer, more informative description is needed for a tool with 5 parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters, required lat/lon, and no output schema, the description is highly incomplete. It does not explain what the tool returns (e.g., image URL, file), date format requirements, or how to obtain an API key. This is insufficient for an agent to use correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning to any of the 5 parameters (lat, lon, date, dim, api_key). Schema description coverage is 0%, and the description does not explain what each parameter does, expected formats, or the role of the API key.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'NASA Earth satellite imagery', but it does not differentiate from sibling tools like nasa_mars_photos or nasa_epic. The name implies Earth imagery but the description lacks specificity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives. The description does not mention prerequisites (e.g., API key) or context for use. Sibling tools exist for other imagery types, but no differentiation is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as destructive potential, authentication requirements, rate limits, or return format. It merely lists actions without any behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence listing actions, which is concise but lacks structure. It does not separate actions, parameters, or usage context, making it minimally informative despite brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 8 parameters, no output schema, and no annotations, the description is severely incomplete. It fails to explain how to use the tool, what each action does, what parameters are needed for each, or what the response looks like.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to any of the 8 parameters. Parameters like 'action', 'api_key', 'search', etc., are left unexplained, so the agent gains no additional insight beyond their names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description lists multiple actions (search_raindrops, get_collection_raindrops, etc.) making the overall purpose clear as a Raindrop.io action dispatcher. However, it does not differentiate from sibling tools like airtable_action or clickup_action, which follow the same pattern, reducing clarity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is given on when to use this tool vs alternatives, nor when to choose each specific action. There are no prerequisites, exclusions, or context for selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It provides none: no mention of whether the deploy is asynchronous, if it returns immediately, side effects, or required permissions. The agent receives no insight into what happens after triggering.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely short—a single sentence that only states the basic purpose. It sacrifices helpful detail for brevity. While concise, it is under-specified and could easily include more context without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity of triggering a deploy (often involves async operations, potential errors, build processes) and the lack of output schema or detailed schema, the description is severely incomplete. It does not explain return values, error cases, or what constitutes a successful trigger.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning beyond the schema. It does not explain that 'api_key' may be needed for authentication, 'service_id' identifies the service, or that 'clear_cache' clears the build cache. Schema coverage is 33% with only 'clear_cache' documented; the description fails to compensate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool triggers a deploy for a Render service. The verb 'Trigger' and resource 'deploy' are specific. It distinguishes from sibling tools like 'render_list_deploys' and 'render_get_service' which are for listing or retrieving, not triggering.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. It lacks context like prerequisites (e.g., a service must exist) or hints about typical use cases such as triggering after code push.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description lacks any behavioral details beyond the basic action. It does not disclose rate limits, authentication requirements (despite api_key being a parameter), pagination, or response size, and there are no annotations to compensate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, which is concise but at the expense of essential information. It does not front-load critical details needed for correct use, making it under-specification rather than effective conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given three parameters, no output schema, and no annotations, the description is highly incomplete. It does not explain pagination, authentication, query syntax, or return format, leaving significant gaps for correct usage.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% (no parameter descriptions in the schema), and the description adds no meaning to the parameters. It fails to explain what 'query' format is expected, how 'page' works, or how to obtain 'api_key'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search' and the resource 'Shodan for internet-connected devices,' making the tool's purpose understandable. However, it does not differentiate from sibling tools like shodan_host_info and shodan_stats, missing an opportunity to clarify scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of when-not-to-use it or any context like prerequisites (e.g., needing an API key), leaving the agent uncertain about appropriate invocation.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden but fails to disclose any behavioral traits. It does not indicate read-only nature, authentication requirements, pagination, or error handling. The bare statement 'get customers' lacks essential context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely short (one sentence), but this is not true conciseness—it omits critical details. It fails to earn its place by providing utility beyond the tool name.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters, no output schema, and no annotations, the description is severely underdeveloped. It does not cover required inputs, authentication, or return values, leaving the agent with insufficient information to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning beyond the input schema. It does not explain the role of parameters like shop_domain, limit, email, api_key, or access_token, nor does it specify the format or constraints for these fields.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get customers from a Shopify store', specifying a verb ('Get') and resource ('customers'). However, it does not differentiate from sibling Shopify tools like shopify_orders or shopify_products, leaving potential confusion about scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., shopify_orders, shopify_products). There is no mention of prerequisites, when not to use, or suggested contexts.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description does not disclose any behavioral traits such as pagination, authentication requirements, or error handling. The description fails to inform the agent about important operational details.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence is concise but lacks structure and substance. Important information is omitted; conciseness does not compensate for under-specification.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 7 parameters and no output schema, the description is severely lacking. It provides minimal context for a tool that needs authentication, filtering, and potentially pagination. Completeness is inadequate for effective tool selection and invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not elaborate on any of the 7 parameters (e.g., meaning of 'limit', 'collection_id', 'api_key'). The agent cannot infer parameter usage from the description alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the action 'Get products' and the resource 'from a Shopify store'. It distinguishes from sibling tools like shopify_collections or shopify_customers by specifying the resource, but lacks further detail to differentiate beyond the resource name.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like shopify_orders or shopify_collections. No context on prerequisites or filtering behavior is provided.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully disclose behavior. However, it only states 'Get TAB sports betting markets' without any details on authentication, data return, side effects, or limitations. For a sports betting data tool, critical behavioral traits are missing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but overly succinct. It lacks structure and fails to provide necessary details, making it insufficient for a tool with multiple parameters and no annotations.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of annotations, output schema, and parameter descriptions, the tool definition is severely incomplete. It fails to convey how to use the parameters, what the tool returns, or any constraints, leaving significant gaps for an AI agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning the description adds no meaning to the three parameters (sport, competition, api_key). It does not explain their purpose, format, or example values, leaving the agent to rely solely on parameter names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get TAB sports betting markets' clearly states the action (get) and the resource (TAB sports betting markets). It is specific and unambiguous, though it does not explicitly distinguish from sibling tools like 'tab_meetings' or 'tab_race', but the name provides adequate context.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. The description does not mention prerequisites, typical use cases, or when not to use it. Sibling tools exist for other TAB services, but no differentiation is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description does not disclose any behavioral traits such as authentication requirements, rate limits, file size constraints, or response format. It only says 'send media', which is insufficient for a tool that modifies state.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but at the expense of necessary detail. While it is not verbose, it fails to convey important information, making it under-specified rather than efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters, no output schema, and no annotations, the description is extremely incomplete. It lacks information on return values, error handling, and any operational nuances, leaving the agent with insufficient context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 20% (only 'media_type' has a description), and the description adds no additional meaning for any parameter. 'bot_token', 'chat_id', 'media_url', and 'caption' are left unexplained, failing to compensate for the low schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool sends media via Telegram, distinguishing it from 'telegram_send' which likely sends text messages. However, it only lists three media types while the enum includes five, causing a minor inconsistency.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 9 parameters, no output schema, and diverse sub-actions, the description is vastly incomplete. An agent cannot infer how to use the tool correctly for any specific action without additional information.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 22% (2 of 9 params have descriptions). The description adds no parameter information beyond the schema—it doesn't map actions to required parameters or explain how 'action' determines usage. This fails to compensate for low schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it's for 'Perform a Bluesky action' and lists specific sub-actions (post, read feed, reply, etc.), so the agent knows the general domain. However, it doesn't explain what each sub-action does, which is a minor gap since the tool is the only Bluesky tool among siblings.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (three parameters, no output schema, many sibling tools), the description is highly incomplete. It does not explain the return format, pagination, error handling, or how membershipType filters. The agent receives insufficient context to use the tool effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has three parameters with only 33% coverage (membershipType has a description '-1 for all'). The description adds no parameter details. The required displayName has no description, and api_key lacks context. The description does not explain how membershipType values affect results or what 'all' means.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches for a Destiny 2 player by display name. It specifies the verb 'search' and the resource 'player', and distinguishes from sibling tools like bungie_get_profile (which gets profile by ID) and bungie_search_entities (which searches generic entities). However, it does not elaborate on the search scope or what information is returned, slightly reducing clarity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema or annotations, the description must provide complete context. It fails to explain what 'mix' means, what the output is, or how ratio affects the result. Incomplete for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. Description adds no meaning to parameters beyond their names. 'Mix two colors together' does not clarify the role of the ratio parameter or expected input formats (e.g., hex codes, RGB).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description states verb+object: 'Mix two colors together.' It clearly indicates the tool combines colors, which is specific and distinguishes from siblings like color_info or color_convert, but does not explicitly differentiate from similar tools like color_palette.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description does not explain any parameter. It does not clarify that 'value' is the numeric input, 'from' and 'to' are unit strings. The agent must infer from names alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The name 'convert_length' and description 'Convert between length units' clearly indicate the tool's purpose. While it doesn't list supported units, the purpose is unambiguous and distinguishable from sibling conversion tools.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, authentication requirements, rate limits, or output format. The phrase 'Search for places' is too vague to inform the agent about side effects or restrictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (4 words), but this under-specification is not beneficial. For a tool with 5 parameters and multiple siblings, it should include more structured information like parameter roles or usage examples.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (5 parameters, no output schema) and presence of sibling tools, the description is completely inadequate. It does not explain what the tool returns, how to construct queries, or when to prefer it over other Foursquare tools.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is only 20% (only 'll' has a description). The tool description adds no parameter explanations beyond what the schema provides, leaving 4 out of 5 parameters undocumented. The agent must infer the purpose of 'query', 'near', 'limit', and 'api_key' from the tool name.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search' and the resource 'places' on Foursquare. However, it does not distinguish itself from sibling tools like foursquare_autocomplete or foursquare_get_place, which may have overlapping functionality.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool vs alternatives (e.g., foursquare_autocomplete, foursquare_get_place). There is no mention of prerequisites like an API key or context for choosing this tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits such as authentication requirements, rate limits, return format, or side effects. This is a significant gap for a search tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at 8 words. While brevity is valued, it sacrifices essential context, making it under-specified rather than efficiently informative.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and many parameters, the description is entirely inadequate. It fails to explain return values, pagination, or how to construct valid requests, leaving the agent with almost no useful information.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the six parameters. The agent must rely solely on parameter names (e.g., 'q', 'section') without any explanation, which is insufficient for correct usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches for articles on The Guardian, which is a specific verb and resource. However, it does not differentiate from sibling tools like guardian_get_article or guardian_search, leaving ambiguity about when to use this vs. others.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description lacks context, prerequisites, or exclusions, leaving the agent without direction for selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description should disclose behavioral traits like rate limits, authentication requirements (api_key parameter), or result behavior (e.g., max results). The single sentence provides none of this, leaving the agent blind to important constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (one sentence, 4 words), but it lacks necessary details for a functional tool. It is front-loaded with the action word, but the brevity comes at the cost of completeness. Could be expanded without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of parameters and no output schema, the description should explain what the search returns (e.g., a list of artists with basic info). Without this, and with no behavioral context, the tool is incomplete for an agent to use effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no information about the parameters. While 'artist' is self-explanatory, 'limit' and 'api_key' are not described in either the schema or the description, forcing the agent to rely on inference.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search for artists on Last.fm' clearly indicates the action (search) and resource (artists on Last.fm). Among siblings like lastfm_artist_info and lastfm_similar_artists, the term 'search' distinguishes it as a general lookup, though it doesn't specify the result structure.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. Siblings like lastfm_artist_info exist for specific artist details, but the description does not clarify that this tool is for broad searches while others are for detailed info. Implicit distinction is insufficient.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and description gives no behavioral details beyond 'search'. Does not mention rate limits, authentication, pagination, output format, or any side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence is concise and front-loaded with the main action, but it lacks detail. It earns its place for brevity but does not provide sufficient context for effective tool selection.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity of a search tool with three parameters and no output schema, the description is incomplete. Lacks information on return values, filtering behavior, and usage context relative to sibling music search tools.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the description does not explain any of the three parameters (query, artist, limit). Does not clarify what 'query' should contain or how 'artist' and 'limit' affect results.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the verb 'Search' and the resource 'releases/albums' on MusicBrainz. Distinguishes from sibling tools like mb_search_artists and mb_search_recordings by specifying 'releases/albums'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as mb_get_release for a specific release or other search tools. No context about prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must fully disclose behavior, but it only says 'Filter meals by category.' It does not specify return format, pagination, or any side effects, leaving the agent without critical operational context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise at one sentence, but it is under-specified. It achieves brevity at the cost of clarity and completeness, which is acceptable only for very simple tools with rich external context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's single parameter and no output schema, the description is severely incomplete. It does not explain what the tool returns, how to use the parameter, or any prerequisites, making it inadequate for an agent to use effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%—the 'category' parameter has no description or enum. The description adds no meaning beyond the parameter name, failing to clarify what values are acceptable or how they relate to meal categories.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Filter' and resource 'meals by category', distinguishing it from sibling tools like meal_filter_by_area and meal_filter_by_ingredient. However, it lacks elaboration on what a 'category' is or how it relates to other meal tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool instead of alternatives such as meal_filter_by_area or meal_filter_by_ingredient. It does not mention that meal_categories can be used to obtain valid categories.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, and the description offers no behavioral details. It does not mention expected behavior (e.g., defaults to today's picture), error handling, rate limits, or authentication requirements. The description is too vague to inform an AI agent about the tool's operational traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it omits critical information. It achieves brevity at the expense of providing necessary context for tool usage. An effective description should balance conciseness with sufficient detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no parameter descriptions, the description is severely incomplete. It fails to clarify what the tool returns (e.g., image URL, text explanation) or how to configure parameters. An agent would lack essential information to invoke the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has three parameters with zero description coverage. The description adds no explanation for date, count, or api_key parameters. Without explicit semantics in the description or schema, an agent cannot correctly use these parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves NASA's Astronomy Picture of the Day (APOD). The verb 'Get' and resource name are unambiguous. While not specifying what exactly is returned (e.g., image URL, metadata), it is distinctive enough among sibling NASA tools (asteroids, Mars photos, etc.).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus other NASA tools or how to apply parameters like date, count, or api_key. Missing context such as date format or whether count yields multiple random images.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must fully disclose behavioral traits, but it offers none. It does not mention pagination, rate limits, data freshness, or the effect of parameters like 'limit' on output, leaving significant behavioral uncertainty.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's multi-action nature, lack of output schema, and zero parameter documentation, the description is grossly incomplete. It omits return values, error conditions, prerequisites, and usage examples for each action.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage and parameters like 'action', 'master_password', 'key', 'value', and 'encrypt', the description adds no meaning beyond listing allowed action values. The AI cannot infer how to use these parameters across different actions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Perform a vault action' and lists six specific sub-actions (vault_init, vault_store, etc.), making the general purpose clear. However, it does not explain what each sub-action does, which is a minor gap.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema, annotations, and parameter details, the description is wholly inadequate for a tool with three parameters. It omits what return values look like, parameter usage, and any contextual guidance.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage and no parameter explanations in the description, the three parameters (symbol, id, api_key) remain completely unexplained. The description adds no value over the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description specifies 'Get cryptocurrency metadata from CoinMarketCap.' It uses a clear verb ('get') and resource ('cryptocurrency metadata'), distinguishing it from sibling tools like cmc_listings or cmc_quotes by implying a focus on basic metadata.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as cmc_quotes or cmc_global_metrics. There are no cues about required parameters or context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must carry the behavioral transparency burden. It does not disclose what date formats are accepted, how invalid inputs are handled, or what the output looks like. The brief description adds no behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (4 words) but at the cost of informativeness. It does not earn its place as it fails to provide any guidance or context that would be useful.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (date formatting with format and locale parameters) and the absence of an output schema, the description is severely incomplete. It does not explain format tokens, locale usage, or return value structure.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must explain the parameters. The description adds no meaning for 'date', 'format', or 'locale' beyond the schema, which only specifies them as strings. This is insufficient.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Format a date string' clearly states the action and the resource. It distinguishes from sibling tools like datetime_convert_timezone which change timezones, and datetime_date_diff which computes differences, so the purpose is clear.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidelines are provided. There is no indication of when to use this tool versus alternatives like datetime_convert_timezone, nor are there any prerequisites or exclusions for using this tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It only indicates a search operation, implying reads, but fails to disclose any behavioral traits such as pagination behavior, rate limits, or result format. Basic transparency is lacking.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is brief, but it is under-specified. It lacks structure and prioritizes brevity over informativeness. Essential details are omitted, making it insufficiently concise in terms of being complete yet concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description should provide comprehensive context. It does not explain what is returned (e.g., list of products, details), how pagination works, or any usage context. The description is severely incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning the description adds no detail about parameters beyond the schema names. The description does not explain what 'query', 'page', or 'page_size' mean, nor their expected formats or constraints. This is a critical gap for a 3-parameter tool.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches for food products on Open Food Facts, distinguishing it from sibling tools like food_by_category (category-specific) and food_get_product (single product). The verb 'search' and resource 'food products on Open Food Facts' are specific, though it could be more precise about the scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like food_by_category or food_get_product. The description does not include any context about suitable use cases, prerequisites, or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavior. It only states 'get the newest stories', omitting return format, limit defaults, pagination, or any side effects. Essential behavioral context is missing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise at one sentence. While brevity is good, the description lacks critical information, making it under-specified rather than efficiently concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool that returns a list of stories, the description fails to specify output format or behavior. Agents cannot know what the tool returns without additional context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. The description does not explain the 'limit' parameter, its meaning, default, or allowed range. Adds no value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Get), resource (newest stories), and source (Hacker News). The term 'newest' distinguishes it from siblings like hn_top_stories or hn_best_stories, but does not explicitly differentiate.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like hn_top_stories or hn_show_hn. No context on prerequisites, scope, or usage restrictions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description lacks any behavioral details beyond restating the purpose. Since no annotations are provided, the description should disclose traits like required authentication (since api_key is a parameter), rate limits, or read-only nature, but none are mentioned.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but underspecified. It fails to front-load important details about parameters or usage, making it minimally useful.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of annotations, output schema, and parameter descriptions, the description is severely incomplete. It does not explain the return format, how the chart is determined, or authentication requirements.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage and no parameter descriptions in the tool description, the agent receives no information about what 'limit' or 'api_key' control. This is a critical gap for correct invocation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it retrieves the Last.fm chart of top tracks, using a specific verb 'Get' and resource. However, it does not distinguish from sibling tools like 'lastfm_top_tracks' which may serve a similar purpose.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as 'lastfm_top_tracks' or other Last.fm tools. There is no mention of prerequisites or appropriate contexts.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, and the description only says 'Get games' implying a read operation. It does not mention authentication (api_key parameter), rate limits, or what is returned, leaving the agent uninformed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, but it lacks substantive information. It is under-specified rather than properly concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 4 parameters, no output schema, and no annotations, the description is far from complete. It does not cover what the tool returns or how to effectively use its parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description fails to explain any of the four parameters. The agent gets no insight into what 'max', 'perfType', or 'api_key' mean.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    States 'Get games for a Lichess user' with a clear verb and resource. However, it does not differentiate from sibling tools like lichess_user or lichess_top_players, which might also involve getting user-related data.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Provides no guidance on when to use this tool versus alternatives, nor any context about prerequisites or limitations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavioral traits. It only states 'List all databases,' which implies a read operation but offers no details about pagination, error conditions, rate limits, or side effects. This is insufficient for safe agent usage.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely short (one sentence), but this brevity comes at the cost of necessary detail. It lacks parameter explanations, return value expectations, and usage context. True conciseness would retain clarity while being informative.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of annotations and an output schema, the description should compensate by explaining what the tool returns (e.g., database names, IDs) and highlighting any caveats (e.g., authentication requirements, branch existence). It fails to do so, leaving the agent with incomplete guidance for a three-parameter tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema lists three parameters (api_key, project_id, branch_id) with zero description coverage. The description does not add any meaning to these parameters, such as indicating that project_id and branch_id are required or that api_key is optional. The agent gains no additional insight from the description.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List all databases on a Neon branch' clearly identifies the action (list), the resource (databases), and the scope (on a Neon branch). This distinguishes it from sibling tools like neon_list_branches (lists branches) and neon_list_projects (lists projects), which target different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus its siblings (e.g., neon_list_branches, neon_list_projects). It does not mention prerequisites, alternatives, or typical use cases, leaving the agent to infer intent from the resource name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It only indicates a read operation but does not mention API key requirements, rate limits, pagination, or whether results are from a specific date range. The tool is a read operation, but details are insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but lacks structure. It omits critical information about parameters and behavior, making it under-specified rather than efficiently concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters, no output schema, and no annotations, the description is severely incomplete. It fails to explain parameters, return format, or any constraints, making it inadequate for correct agent invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 5 parameters with 0% description coverage. The tool description provides no additional meaning or context for any parameter, leaving the agent to guess the purpose of 'country', 'category', 'q', 'pageSize', and 'api_key'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves top headlines from NewsAPI, specifying the verb, resource, and source. However, it does not differentiate from sibling tools like 'news_search' or 'news_get_sources'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool over alternatives. There is no mention of prerequisites, limitations, or scenarios where this tool is preferred.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for behavioral disclosure. It does not mention authentication needs (though an api_key parameter exists), rate limits, destructive potential (create, update actions), or any side effects. The description is silent on these critical aspects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but severely under-specifies the tool. Given the complexity (8 parameters, multiple actions, nested objects), the description is too brief and lacks structure (no parameter sections or usage examples). It is not appropriately sized.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    This tool has high complexity (8 parameters, multiple sub-actions, nested objects, no output schema, no annotations). The description provides only a list of action names, leaving the agent without context on how to invoke each action, what parameters are required for each, or what the responses look like. It is woefully incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning no parameter descriptions exist in the schema. The tool description adds no meaning beyond listing the parameter names. For instance, the 'action' parameter's allowable values (the listed sub-actions) are not formally indicated, and other parameters like query, page_id, etc. have no explanation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Perform a Notion action' and lists six specific sub-actions (search, get, query, create, update), making the tool's purpose reasonably clear. However, it does not differentiate this dispatcher tool from other Notion-related tools (which are absent), but the list of sub-actions is helpful.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use specific sub-actions, nor does it explain when not to use the tool or suggest alternatives. The agent must infer appropriate usage from the action names alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description fails to disclose any behavioral traits such as side effects, network calls, or performance characteristics. The agent has no insight into what happens when the tool is invoked.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    While extremely concise (one sentence), it lacks necessary detail. Conciseness is appropriate but at the cost of completeness, under-informing the agent.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 2 parameters, no output schema, and no annotations, the description fails to provide enough context for effective use. The agent cannot infer return format, error states, or parameter constraints beyond the schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema parameter descriptions cover only 50% (type has a description), and the tool description adds no meaning beyond the schema. It does not explain what 'number' expects or how 'type' affects the returned fact.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('Get') and the resource ('an interesting fact about a number'), which distinguishes it from sibling tools like number_random. It is specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. The description does not mention scenarios, exclusions, or related tools, leaving the agent without context for selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but fails to disclose any behavioral traits such as authentication needs, rate limits, or data freshness. The minimal description adds no value beyond the name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but severely under-specified for a tool with four parameters. Conciseness should not come at the cost of utility.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and 100% undocumented parameters, the description provides almost no context. The agent cannot infer return type, pagination, or expected behavior.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% and the description does not explain any parameter (city, country, parameter, limit). The agent gets no semantic help beyond raw names, making correct invocation difficult.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'air quality data' from OpenAQ, making the core purpose understandable. However, it does not differentiate from sibling tools like openaq_countries or openaq_measurements, which is a missed opportunity for clarity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, nor any prerequisites or conditions. The description is silent on context, leaving the agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description fails to disclose any behavioral traits such as whether results are cached, paginated, or ordered. The agent has no insight into side effects or data freshness.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    While the description is a single short sentence, it is under-specified and omits critical information (e.g., parameter semantics, output format). True conciseness balances brevity with completeness, which is not achieved here.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has only one parameter and no output schema, the description should explain the parameter and typical results. It fails to do so, leaving the agent without enough context to use the tool effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has one parameter ('limit') with no description and 0% coverage. The description does not explain what 'limit' controls, its default value, or valid range, providing no value beyond the raw schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'most-clicked radio stations', which distinguishes it from sibling tools like radio_top_voted (top voted). It specifies the selection criteria ('most-clicked'), making the purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus siblings like radio_top_voted or radio_search. There is no discussion of context, exclusions, or alternatives, leaving the agent to infer usage without support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states 'Search' without mentioning authentication needs, rate limits, or what the response contains. The tool's behavior beyond being a read operation is opaque.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely brief (one sentence), which sacrifices essential detail. While it is concise in length, it is under-specified and misses key information like parameter meanings, default behavior, and output format. True conciseness should preserve completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description should explain return values but does not. It also fails to document most input parameters. For a search tool with 6 parameters and multiple sibling tools, this description is severely incomplete for an agent to use correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 17% (only the 'search' parameter has a description). The tool description adds no information about the other five parameters (genres, platforms, ordering, page_size, api_key). With low coverage, the description fails to compensate, leaving most parameters undocumented.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (search) and the resource (video games on RAWG). It is a specific verb+resource pair. While it does not differentiate from sibling tools like rawg_get_game or rawg_upcoming_games, the action 'search' is distinct from 'get' or 'list' operations, making the purpose reasonably clear.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as rawg_get_game (for a specific game) or rawg_list_genres (for genre metadata). There are no instructions on prerequisites, use cases, or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so the description must carry the burden. It merely says 'Search for events' without disclosing return format, pagination, rate limits, or any behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is underspecified rather than concise. It lacks essential details to fill the 5-parameter interface.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 5 parameters, no output schema, and no annotations, the description is grossly incomplete. It fails to explain what the search returns or how to effectively use it.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage and no explanation of parameters (q, type, datetime_utc_gte, per_page, api_key) in the description, the agent has no clue about their meaning or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search' and the resource 'events on SeatGeek,' distinguishing it from sibling tools that focus on getting specific entities or searching performers/venues. However, it could be more specific about the scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like seatgeek_get_event or seatgeek_search_performers. No context on query requirements or filtering logic.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should fully disclose behavior such as authentication (api_key), rate limits, or response format. It does none of this, simply stating 'Search for venues on SeatGeek' without any behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at 4 words, but it is under-specified. Conciseness should not come at the cost of completeness; every word should earn its place, but here it fails to provide necessary details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema and zero schema coverage, the description must explain the result format (e.g., list of venues) and how to use the parameters. It is completely inadequate for a tool that requires user input and returns data.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the parameters 'q' and 'api_key'. The agent receives no hints about what 'q' should contain or how to provide the API key.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search' and resource 'venues' on 'SeatGeek', distinguishing it from sibling tools like seatgeek_get_venue and seatgeek_search_events. However, it does not specify what the search query 'q' represents (e.g., name, location), leaving some ambiguity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool vs alternatives like seatgeek_get_venue for a specific venue. The description does not mention prerequisites or context for searching venues.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral disclosure. It fails to mention any side effects, required permissions, or what constitutes successful invocation. The bare statement offers no transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    While the description is concise at one sentence, it sacrifices necessary detail. It is under-specified rather than efficiently comprehensive.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and four undocumented parameters, the description is deeply incomplete. It does not equip the agent to understand inputs or outcomes.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has four parameters with zero description coverage. The description adds no meaning for any parameter. The agent must guess the expected structure for 'sender', 'receiver', 'parcel_contents', and 'api_key'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Create a Sendle shipping order,' specifying a verb and resource. It effectively distinguishes the tool from its siblings like sendle_get_quote and sendle_track_parcel.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. The agent is left without context for appropriate choice.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden for behavioral disclosure. It only states 'Get orders' without mentioning authentication (e.g., api_key, access_token), rate limits, or what constitutes a 'get' (e.g., does it support pagination?). This is insufficient for a tool with sensitive parameters.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, which is concise in length but lacks substantive information. It is under-specified rather than efficiently informative, failing to add value beyond the tool name.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 6 parameters, no output schema, and no annotations, the description is severely incomplete. It provides no context about output format, pagination, filtering, or authentication, leaving critical gaps for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 6 parameters with 0% description coverage in the schema. The description adds no explanation for parameters like shop_domain, limit, status, financial_status, api_key, or access_token. Without any parameter context, the agent cannot correctly populate these fields.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Get orders' and the resource 'from a Shopify store'. It is specific enough to convey the basic purpose, but it does not differentiate from sibling tools like shopify_fulfillments or shopify_products, which also involve orders.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as shopify_fulfillments or shopify_products. The description lacks context for filtering, authentication, or prerequisites, leaving the agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must disclose behavioral traits. It fails to mention authentication requirements, pagination, rate limits, or default behavior for omitted parameters.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    While the description is a single sentence, it is under-specified. Conciseness should not sacrifice essential information; here the description is too minimal.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has five parameters, no annotations, and no output schema, the description is severely incomplete. It does not explain parameter purpose, usage context, or expected output.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% and the description adds no information about any of the five parameters (e.g., broadcaster_id, client_id, first). Agents cannot understand what each parameter does.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Get clips) and the target (Twitch broadcaster), distinguishing it from sibling tools like twitch_get_stream or twitch_channel_info.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs. alternatives, no mention of prerequisites (e.g., authentication), and no clarification on which parameters are typically needed for a valid request.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, authentication requirements, rate limits, or pagination. The description carries the full burden but adds no behavioral context beyond the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise at five words, but it is under-specified for a tool with three parameters. Being concise should not come at the expense of necessary detail; this is closer to inadequate than concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given three parameters, no output schema, and no annotations, the description should provide more context about what the search returns and how parameters affect results. It is far from complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain any of the three parameters (name, client_id, client_secret). It fails to add meaning beyond the schema, such as noting that client_id and client_secret are optional or for authentication.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search for games on Twitch.' clearly states the action (search) and resource (games on Twitch). It effectively distinguishes from sibling tools like twitch_top_games and twitch_search_streams, as it focuses specifically on game search.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like twitch_top_games. There is no mention of prerequisites such as authentication with client_id/client_secret, nor any exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description must disclose all behavioral traits. It mentions searching but omits details on pagination, rate limits, result format, error handling, or authentication requirements (despite an api_key parameter). This leaves significant gaps.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    While extremely short, the description is under-specified rather than concise. It lacks critical details that would justify its brevity. Every word is used, but it fails to convey necessary information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the three parameters, no output schema, and no annotations, the description is grossly incomplete. It does not cover search behavior, limits, authentication, or expected results, leaving the agent without essential context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the three parameters (query, limit, api_key). It does not explain what the query expects, how limit affects results, or the purpose of api_key.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Search') and the resource ('beers on Untappd'), providing a specific verb+resource. However, it does not differentiate from sibling tools like 'untappd_get_beer' or 'untappd_search_brewery', which could cause confusion.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, such as 'untappd_get_beer' for specific beers or 'untappd_search_brewery' for breweries. The agent receives no context on appropriate usage scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden for behavioral disclosure. It only states the tool gets earthquakes, but fails to mention any safety aspects, rate limits, data source specifics, or that it is a read-only operation. This leaves the agent unaware of any important behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but lacks structure and substance. It does not use any formatting (e.g., bullet points) to aid readability or highlight key aspects.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (7 parameters, no output schema, no annotations) and the minimal description, the description is severely incomplete. It does not explain the bounding box coordinates, time range, magnitude filtering, or response format, leaving substantial gaps for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage and 7 parameters, the description adds no meaning to the parameters. It does not explain minlatitude, maxlatitude, minlongitude, maxlongitude, minmagnitude, starttime, or endtime, forcing the agent to infer or guess their meaning.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states it retrieves USGS earthquakes within a geographic region, specifying verb 'Get', resource 'USGS earthquakes', and scope 'within a geographic region'. This distinguishes it from sibling tools like usgs_earthquake_detail (single earthquake) and usgs_recent_earthquakes (recent events without region filtering).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as usgs_earthquake_detail or usgs_recent_earthquakes. The description lacks context about preferred scenarios or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description only states the basic action, with no annotations available. It does not disclose any behavioral traits such as rate limits, authentication requirements, or what the returned data includes (e.g., list of suggestions). The api_key parameter is not mentioned, even though it is in the schema. This is insufficient for an agent to understand the tool's behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (one short sentence), but it sacrifices essential information. While brevity is good, this is under-specification. It should include parameter details or usage context to be valuable.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity of 4 parameters (including an api_key) and no output schema or annotations, the description is grossly incomplete. It fails to clarify the role of latitude/longitude, whether api_key is required, or what the autocomplete response contains. A complete description would at least mention these aspects.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 4 parameters with 0% description coverage. The description provides no explanation for any of the parameters (text, latitude, longitude, api_key). The agent has no guidance on what each parameter means or how to use them, which is a critical gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Autocomplete') and resource ('a Yelp business search'). It is specific enough to distinguish from sibling tools like yelp_search_businesses, which searches for businesses, while this provides autocomplete suggestions. However, it lacks any details about the scope or output format.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. It does not mention when to use autocomplete vs. search, nor does it provide any context about prerequisites or typical use cases. The description simply states what it does without any usage direction.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavior. It only states what the tool does, not how it behaves (e.g., what it returns, authentication requirements, rate limits). The description is too minimal to compensate for the lack of annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence and is very short. While brevity can be good, it is under-specified and does not earn its place because it omits necessary details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters (1 required, 0% schema coverage, no output schema, no annotations), the description is vastly insufficient. It does not explain the concept of variations, how to use auth parameters, or what the output format is.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% (no parameter descriptions). The description does not explain any parameter, including the required 'asin' or optional auth fields. It adds no value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the action (get), resource (Amazon product variations), and key input (ASIN). However, it does not differentiate from sibling tools like amazon_product or amazon_search, so the purpose is clear but not uniquely defined.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. Does not mention that this is for listing variations of a product, while amazon_product might be for single product details. No exclusions or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It says 'Get', implying a read operation, but fails to disclose important behavioral traits such as authentication requirements, response format (e.g., a URL to a JSON file), or potential rate limits. The agent cannot infer the tool's behavior beyond a basic get.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of six words, which is concise but lacks any structure. It borders on under-specification rather than effective conciseness. A well-structured description would front-load key details and provide context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations, no output schema, and a single undocumented parameter, the description is severely incomplete. It does not explain what the manifest definition contains, how to interpret the result, or any constraints. The agent lacks essential information to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema shows one parameter 'api_key' with no description, and the tool description adds no meaning. It does not explain what the api_key is for, how to obtain it, or its role in accessing the manifest. With 0% schema description coverage, the description completely fails to compensate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get the Destiny 2 manifest definition' with a specific verb and resource. However, it does not differentiate from sibling tools like bungie_get_profile or bungie_search_entities, leaving room for ambiguity about what the manifest is.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites, typical use cases, or context such as whether this is a first step in interacting with Destiny 2 API.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description carries full burden. It only says 'calculate', implying a read-only operation, but fails to disclose return format, potential side effects, or constraints like rate limits. The description adds minimal behavioral context beyond the verb.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, front-loaded and concise. However, it is too brief, sacrificing essential details. It earns its place but could be expanded to be more useful without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters and no output schema, the description fails to explain what the output represents (e.g., future value, total interest) or the role of optional parameters. The agent lacks sufficient context to use the tool confidently.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% for 5 parameters. The description does not explain any parameter's meaning or format (e.g., what 'annual_rate' expects, whether 'compounds_per_year' has a default). The agent has no semantic help beyond parameter names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Calculate') and resource ('compound interest growth'), clearly distinguishing it from siblings like calc_mortgage or calc_tip. However, it lacks detail on what exactly is returned (e.g., future value, interest earned).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description merely states what it does, leaving the agent to infer context without explicit when-to-use or when-not-to-use instructions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral disclosure, but it merely states the action. It does not describe what specific statistics are returned, any authentication requirements, rate limits, or data freshness.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise with a single sentence, but it is too minimal for an agent to use effectively. While it is front-loaded, it lacks structure and additional contextual sentences that would be expected for a 1-parameter tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one parameter, no output schema, no annotations), the description is not complete enough. It fails to explain what the output contains or any nuances about the player username, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has a single parameter 'username' with no description (0% coverage), and the tool description adds no additional meaning. An agent has no information about valid username formats, case sensitivity, or whether it is the Chess.com username.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'Chess.com player statistics,' which conveys the tool's basic purpose. It is distinguishable from sibling tools like chess_leaderboards and chess_player_games, as 'statistics' implies a broader data set than a simple profile or games list.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No indication is given about when to use this tool versus alternatives such as chess_player or chess_player_games. The one-line description lacks any guidance on context or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden of disclosing behavioral traits. It fails to mention what happens on duplicate subscription, error handling, rate limits, or authentication requirements. Simply stating 'subscribe' is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very short (one sentence), which is concise but lacks structure. It is front-loaded with the verb, but could be expanded with minimal additional context without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a mutation tool with no output schema and low parameter documentation, the description should provide more context about the return value, side effects, or integration specifics. It is incomplete.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is only 25% (api_key described), and the description adds no parameter details. It doesn't clarify what form_id or email should be, or that first_name is optional.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (subscribe) and resource (email address to a ConvertKit form), distinguishing it from sibling tools like ck_list_subscribers or ck_tag_subscriber. However, it could be more explicit about the subscription being tied to a specific form.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives (e.g., ck_tag_subscriber) or prerequisites (e.g., need a ConvertKit account and form). The description lacks any context about appropriate use cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral disclosure. It only states the action without detailing side effects, permission requirements, or what happens if the subscriber does not exist.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise at one sentence, but it sacrifices necessary detail. It is not a tautology, but the brevity results in under-specification for a tool with 4 parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations, no output schema, and 0% schema description coverage, the description fails to provide complete context. It does not explain how to use the tool or what to expect from the operation.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description does not disclose behavioral traits such as authentication needs, rate limits, data freshness, or return format. Agent cannot infer safety or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single 7-word sentence, front-loaded and without fluff, but it omits important details, making it under-specified rather than efficiently concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no annotations, no output schema, and a single parameter with zero description coverage, the description fails to provide essential context like what metrics are returned, authentication behavior, or data structure. Incomplete for a data retrieval tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers the api_key parameter with 0% description coverage, and the description adds no meaning about the parameter's purpose, optionality, or expected format. Agent gets no value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description specifies a clear verb (Get) and resource (global cryptocurrency market metrics), which distinguishes it from sibling CMC tools like cmc_info, cmc_listings, cmc_quotes, and cmc_trending. However, it does not explicitly differentiate or clarify what 'global metrics' includes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like cmc_quotes or cmc_listings. No context on prerequisites, required parameters, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It only states the core function, omitting details like rounding behavior, tolerance, or handling of invalid units. The tool likely performs standard conversions, but the description offers no assurance.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that gets to the point. However, it is too brief given the lack of parameter explanations, sacrificing completeness for brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has three required parameters with no schema descriptions and no output schema, the description is incomplete. It does not specify how units should be represented (e.g., 'C' vs 'celsius') or confirm bidirectional conversion. An agent would need additional documentation to use it reliably.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, but the description adds no parameter information. It does not explain that 'value' is the numeric input, 'from' and 'to' specify source/target units. The agent must guess from parameter names and types.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool converts temperature units and lists the specific units (C, F, K). This distinguishes it from sibling converters like convert_length or convert_volume. However, it could be more explicit about the conversion direction (e.g., any unit to any other).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite having 10 input parameters, no output schema, and no annotations, the description provides almost no contextual information. It fails to explain what fields are returned, how sorting or filtering works, or basic usage patterns, leaving the agent to guess from parameter names alone.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is approximately 50%, and the description adds no additional meaning to any parameters. For example, it does not explain how min_price/max_price work or the effect of taxonomy_id. The tool's search behavior is left implicit.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches active Etsy listings by keyword, distinguishing it from siblings like etsy_get_listing or etsy_search_shops. However, it could be more precise about the scope (e.g., only active listings) and the exact resource type.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description bears full responsibility. It states 'list' implying read-only behavior but does not disclose potential side effects, auth requirements, rate limits, or pagination. This is insufficient for a production tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise (one sentence) but lacks structure or additional sections. It is not verbose but is under-specified, which is not a virtue of conciseness but rather minimalism.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of output schema and parameter details, the description fails to provide a complete picture. The agent cannot infer what the return format is or whether the list is paginated, making the tool unreliable without external knowledge.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage, and the tool description does not explain the single parameter 'api_key'. The agent has no clue what value to provide or how to obtain it, rendering the parameter virtually useless.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists Eventbrite event categories, with a specific verb and resource. However, it does not differentiate from sibling Eventbrite tools like eventbrite_search_events, which also list categories implicitly.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. The description provides no context about prerequisites or exclusions, leaving the agent without decision-making information.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description does not disclose behavioral traits like read-only status, rate limits, or data freshness. The verb 'Get' implies a read operation, but this is not explicit. The description carries the full burden for behavioral transparency but fails to provide meaningful context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no extraneous content, making it efficient. However, its brevity comes at the cost of completeness, as it omits essential details about usage and parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given two required parameters, no output schema, no annotations, and many sibling F1 tools, the description is insufficient for an agent to use the tool effectively. It fails to explain what the returned telemetry contains or how to construct a valid request.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description must compensate but does not. The parameters 'session_key' and 'driver_number' are not explained, despite being required. The description adds no meaning beyond what the schema's types (number) reveal, leaving agents to guess their semantics.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Get Formula 1 car telemetry data from OpenF1,' which clearly identifies the tool's purpose as retrieving telemetry data. However, it does not specify what telemetry fields are included (e.g., speed, throttle), limiting clarity compared to more detailed alternatives. It distinguishes from siblings like f1_laps or f1_positions by explicitly mentioning 'car telemetry data.'

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus other F1 tools such as f1_laps, f1_pit_stops, or f1_weather. The description lacks any context for selection or exclusion, leaving the agent to infer usage solely from the name and schema.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for behavioral transparency. It fails to disclose rate limits, required authentication, data freshness, or the effect of omitting parameters. The only hint is the data source 'OpenF1', but this is insufficient for safe use.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, achieving conciseness. However, the sentence is vague and does not efficiently convey essential details. It is front-loaded with the action but lacks substance in terms of scope and usage.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 2 optional parameters, no output schema, and many sibling F1 tools, the description is incomplete. It does not clarify what 'driver info' entails, how to filter, or what the return format is, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning parameter names and types are documented but their meaning is not. The description adds no explanation of `session_key` or `driver_number` (e.g., whether they are filters or identifiers). This forces the agent to guess parameter semantics.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'driver info' from 'OpenF1', indicating a retrieval operation. However, it does not differentiate from sibling F1 tools like f1_sessions or f1_car_data, missing an opportunity to specify exactly what driver information is provided.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description only states the basic purpose. It fails to disclose any behavioral traits such as read-only nature, data source freshness, error handling, or required authentication, leaving the agent with minimal context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely short (6 words), which is concise but sacrifices necessary detail. It is front-loaded with the action, but the brevity leaves out parameter context, making it less useful overall.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the three parameters and lack of output schema, the description is incomplete. It does not clarify what data is returned, how parameters relate, or how this tool differs from siblings, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage, and the description does not explain any parameter. The meanings of 'session_key', 'driver_number', and 'lap_number' are left entirely to the agent to infer from names, which is insufficient for correct invocation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get Formula 1 lap data', using a specific verb and resource. It implicitly distinguishes from sibling tools like f1_car_data or f1_drivers by focusing on 'lap data', though it could be more precise about the type of lap data.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Clearly states the tool checks if an email account has been in a data breach. However, it does not differentiate from sibling tools like 'hibp_all_breaches' which may also check email accounts, leading to potential confusion.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., 'hibp_all_breaches' or 'hibp_check_password'). Lacks context on prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description must fully explain behavior. Only says 'Get the top stories,' omitting details like response format, pagination, rate limits, or whether it returns story IDs or full items.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Description is a single short sentence, which is concise, but it lacks structure and fails to convey necessary information beyond the tool's basic function.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no annotations, no output schema, and one undocumented parameter, the description is severely incomplete. An agent cannot effectively determine how to use this tool or interpret its results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema describes one optional 'limit' parameter with type number but no description. The tool description doesn't mention the parameter or its purpose, leaving the agent to guess what 'limit' controls (e.g., number of stories).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states it retrieves top stories from Hacker News, but doesn't distinguish from sibling tools like hn_best_stories, hn_new_stories, etc., which have similar purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool instead of alternatives like hn_best_stories or hn_new_stories. No prerequisites or exclusions mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as rate limits, authentication requirements, or error handling. It does not compensate for the lack of annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise but at the expense of necessary detail. It is a single sentence that lacks important information about parameters and behavior.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 4 parameters, 0% schema coverage, no output schema, and no annotations, the description is completely inadequate. It fails to explain optional parameters, output format, or any usage context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning beyond the parameter names. The purpose of optional parameters like first_name and last_name is not explained, nor is the need for an API key.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (find email addresses) and the resource (domain) and the service (Hunter.io). However, it does not differentiate from sibling tools like hunter_domain_info or hunter_verify_email, which may have overlapping purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description must disclose behavioral traits. It fails to mention that the tool requires an API key for authentication, any rate limits, or what the response contains (e.g., artist names, play counts). The description only indicates it is a read operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence of 8 words, which is efficient. However, it sacrifices necessary detail; a slightly longer description would be more valuable.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of annotations, output schema, and parameter descriptions, the tool is incomplete for an agent to use effectively. It does not convey authentication requirements, chart definition, or return structure. While simple, it requires external knowledge.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description provides no explanation of the 'limit' and 'api_key' parameters. The agent receives no meaning beyond the parameter names themselves.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'Last.fm chart of top artists', which distinguishes it from sibling tools like lastfm_chart_top_tracks. However, it does not specify the chart period or scope (e.g., weekly, overall), which could add clarity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as lastfm_top_tracks, lastfm_search_artists, or lastfm_chart_top_tracks. The description lacks any context for selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It only states 'list customers' without mentioning pagination, authentication needs (api_key), rate limits, or the scope of results. The description adds minimal value beyond the name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise. However, it sacrifices necessary details for brevity, making it less useful despite its conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (5 parameters, no output schema), the description is severely incomplete. It lacks information on pagination, filtering, output format, and required parameters, failing to equip the agent for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description does not mention any parameters. It fails to explain the roles of api_key, store_id, email, page, and per_page, leaving the agent without guidance on how to use them.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (List) and resource (customers for a Lemon Squeezy store), making the purpose evident. It is distinct from sibling tools like ls_list_stores and ls_list_orders.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, filtering, or context for selecting this tool over similar list tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description must carry the full burden of behavioral disclosure. It only states 'Search for artists on MusicBrainz' without mentioning that it is a read-only operation, any rate limits, authentication requirements, or what the response contains. Critical behavioral traits are omitted.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise, consisting of a single sentence. However, it lacks any structure such as sections for usage or parameters. For a simple search tool, this might be minimally acceptable, but it does not earn its place by providing additional value beyond the tool name.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's low complexity (two parameters, no output schema), the description should still cover basic completeness. It does not mention that the operation is safe/read-only, nor does it hint at the return format (e.g., list of artist objects). Sibling tools like mb_search_recordings have similarly terse descriptions, indicating a pattern, but the description is incomplete for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning the schema itself provides no parameter descriptions. The description adds no meaning to the 'query' or 'limit' parameters. It does not explain what 'query' should be (artist name, MBID?) or how 'limit' controls results. This is a significant gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search', the resource 'artists', and the platform 'MusicBrainz'. This distinguishes it from other search tools like mb_search_recordings and mb_search_releases. However, it does not specify the type of search (e.g., by name or MBID) which could be more precise.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternative artist search tools from other platforms (discogs_search_artists, lastfm_search_artists, etc.). The description does not mention context, prerequisites, or situations where this tool is preferred.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for behavioral disclosure. It does not mention whether this is a read-only operation, what happens if the ID is invalid or missing, or any other behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise. However, it sacrifices necessary details that an agent needs to use the tool correctly. It is not appropriately sized for the context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description fails to explain what the function returns, how to interpret the response, or error handling. It is incomplete for a tool with a single parameter and no semantic coverage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds minimal meaning beyond the parameter name 'id' - it states 'by ID' but does not explain the format, source, or constraints of the ID. With 0% schema description coverage, this is insufficient.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'get' and resource 'meal/recipe by ID', but it is generic and does not differentiate from sibling tools like meal_search or meal_random, which also fetch meals. The purpose is understandable but lacks specificity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus other meal tools (e.g., meal_search for finding by name). No context on prerequisites or typical use cases is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description is minimal and does not disclose behavioral traits such as rate limits, authentication requirements (api_key is a parameter but not explained), pagination, or result format. Since annotations are absent, the description carries the full burden but provides almost nothing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but at the cost of informativeness. It is front-loaded with the core function, but the extreme brevity results in missing essential details, making it minimally adequate.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 7 parameters including an API key, no output schema, and no annotations, and there are sibling news tools, the description is very incomplete. It explains nothing about parameter usage, search behavior, or when to use this over alternatives, leaving significant gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage and no parameter explanations in the description, the agent has no additional meaning beyond parameter names. The description fails to compensate for the lack of schema descriptions, leaving all 7 parameters unexplained.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Search news articles via NewsAPI', clearly indicating the verb (search) and resource (news articles) and the source API. However, it does not differentiate from sibling tools like 'news_top_headlines' or 'news_get_sources', so it lacks sibling distinction.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of context, prerequisites, or exclusions, leaving the agent without direction on appropriate usage.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description bears full responsibility for behavioral disclosure. It only states 'Search books on Open Library', revealing no behavioral traits such as whether the operation is read-only (likely), if rate limits apply, or what the response structure is. This is insufficient for a tool with no annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise (one short sentence) with no wasted words. However, this brevity comes at the expense of completeness, making it feel under-specified rather than elegantly compact.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has no output schema, no annotations, and 3 parameters with no descriptions, the description is far from complete. It does not explain what the search returns, how pagination works, or any constraints. A complete description would need to address these gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds zero meaningful information about the three parameters (q, limit, page). Given that the schema has 0% description coverage, the description should at minimum explain that 'q' is the search query. It fails to do so, leaving the agent to guess parameter purposes.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search books on Open Library' clearly states the tool's function (search) and resource (books on Open Library). It is specific enough to differentiate from other Open Library tools like openlibrary_get_book or openlibrary_trending, though it could be more explicit about the type of search (e.g., by title, author).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like openlibrary_author_works or openlibrary_get_book. There is no mention of typical use cases, prerequisites, or when not to use it. The description is purely functional without usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided. The description does not explain what 'recent' means, any limitations on episode count, authentication requirements implied by api_key and api_secret parameters, or any other behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, but it is too sparse. Valuable space is wasted by not adding context about parameters or usage.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With zero output schema, no parameter descriptions, and no annotations, the description is incomplete. It fails to inform the agent about return format, pagination, or authentication details, which are critical for a tool with optional auth parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the description adds no meaning to the parameters (max, api_key, api_secret). The agent cannot infer what 'max' controls or that api_key/api_secret are for authentication without external knowledge.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get recent podcast episodes from Podcast Index,' providing a specific verb and resource. However, without differentiating from sibling tools like podcast_get_episodes or podcast_search_episodes, it lacks precision.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is given on when to use this tool versus alternatives. Sibling tools include podcast_get_episodes, podcast_search_episodes, and podcast_trending, but the description offers no context for selection.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and zero parameter schema coverage, the description is extremely incomplete. It does not explain what the search returns, how to authenticate, or the meaning of any parameters. The agent is left with very little to work with.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has zero description coverage, and the description adds no information about the parameters. The agent has no clue what 'q', 'max', 'api_key', or 'api_secret' mean or how to use them correctly.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search', the resource 'podcast episodes', and the platform 'Podcast Index'. This distinguishes it from sibling tools like 'podcast_get_episodes' and 'podcast_search'. However, it could be more specific about the type of search (text query).

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 5 parameters, no output schema, and no annotations, the description is severely incomplete. It does not cover return format, pagination, filtering, or authentication, leaving major gaps for tool invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has only 20% description coverage, yet the description adds no meaning to any parameter. It fails to explain stop_id, route_id, max_results, or api_key, leaving the agent with minimal understanding of their roles.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states the verb 'Get' and resource 'PTV departures' with scope 'for a stop', making the core action clear. However, it does not differentiate from sibling tools like ptv_disruptions or ptv_route_directions, lacking specificity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. The description is too brief to provide usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden for behavioral disclosure. It only says 'search', which implies a non-destructive read operation, but it omits details like authentication requirements (api_key), rate limits, or any side effects. The description is insufficient for a tool with no annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, but it sacrifices necessary detail. While brevity is good, the sentence does not earn its place as it lacks important context. It is under-specified rather than efficiently concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple two-parameter tool with no output schema, the description should at least indicate the nature of the response (e.g., list of matching items). It does not. The tool's overall completeness is inadequate for reliable agent invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, both parameters ('search_term' and 'api_key') are undocumented in the schema. The description adds no information about their expected format, constraints, or purpose beyond their names. The description fails to compensate for the missing parameter descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'search' and the resource 'PTV stops, routes, or outlets'. This differentiates it from sibling tools like ptv_departures or ptv_stops_on_route which are more specific. However, it could be more precise about what constitutes a search result (e.g., matching entities).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus its siblings. For example, it does not clarify that ptv_search is for general textual search while ptv_stops_on_route is for stops on a specific route. This leaves the agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must fully disclose behavior. It only states the tool gets most-voted stations but omits details like sorting order, pagination, or what 'most-voted' means, leaving significant ambiguity.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words, but it is too brief to be fully informative. Conciseness is achieved at the expense of completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and minimal description, the tool definition is incomplete. An agent cannot infer the response format, how 'most-voted' is determined, or how to use the limit parameter effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The only parameter 'limit' has 0% schema description coverage, and the description does not mention it at all. It adds no meaning beyond the schema, failing to explain its purpose or effect.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves the most-voted radio stations, using a specific verb and resource. However, it does not differentiate from the sibling tool 'radio_top_clicked', which has a similar scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like radio_top_clicked or radio_search. The description lacks context for selecting this tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Lacks annotations and description omits details: fairness, possible outcomes (heads/tails), return format, or side effects. Very limited behavioral insight.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise (three words) but sacrifices necessary details. Sentence is front-loaded but incomplete.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one optional parameter and no output schema, the description fails to cover parameter semantics, return value, or use cases.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage 0% for the times parameter, and description provides no explanation of its meaning or usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly indicates a coin flip, but does not distinguish from sibling random tools like random_roll_dice or random_number. Could mention multiple flips from the times parameter.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives. Sibling tools include many random operations with no differentiation.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It does not disclose that the operation is read-only, whether authentication is required (the 'api_key' parameter suggests it), or any behavioral aspects like rate limits or response size. The single sentence adds no behavioral context beyond the tool's name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise (one sentence) but overly terse. It lacks structure; key information like parameter details or return format is missing. While brevity is good, it sacrifices usefulness for the agent.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (2 parameters, no output schema), the description is incomplete. It does not hint at the return format (e.g., list of screenshot URLs) or any constraints like pagination. The agent cannot fully understand the tool's behavior from this description alone.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the parameters. It does not explain that 'id' is the game ID or how to obtain it, nor does it clarify the 'api_key' parameter's purpose or optionality. The description fails to compensate for the lack of parameter documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves screenshots for a RAWG game, with a specific verb ('Get') and resource ('screenshots for a RAWG game'). It distinguishes itself from sibling tools like 'rawg_get_game' or 'rawg_search_games'. However, it lacks detail on what exactly is returned (e.g., all screenshots or a subset), which slightly reduces clarity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool vs. alternatives. The description does not mention when not to use it, nor does it differentiate usage from siblings like 'rawg_get_game' or 'rawg_search_games'. The context is implied but not stated.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It does not disclose behavioral traits such as API key requirements, rate limits, or whether it returns a list or single item. It only states the basic purpose.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Very concise with one sentence, but lacks necessary details. While it earns its place, it is under-specified for effective use.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations and no output schema, the description is incomplete. It does not mention return format, pagination, or ordering, which are critical for a list tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description adds no meaning to the parameters (page_size, api_key). It does not explain their purpose, leaving the agent to guess.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (Get) and resource (upcoming game releases from RAWG), distinguishing it from related tools like rawg_search_games. However, it does not explicitly differentiate from siblings.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like rawg_search_games. No context about prerequisites or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the burden of behavioral disclosure. It does not state whether actions are read-only or mutating (e.g., create_highlight is a write, others are reads), nor mention authentication, rate limits, or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very short and front-loaded with the core action list, but it lacks essential details. It is concise in length but not in informational value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (6 parameters, no output schema, no annotations), the description is highly incomplete. It does not explain what each action does, required parameters per action, or return values. The agent would struggle to use this tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no information about parameters like api_key, query, page, etc. The agent must infer parameter usage from the action names alone, which is insufficient.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it performs a Readwise action and lists the specific actions (get_readwise_highlights, get_readwise_books, etc.), making the purpose clear. However, it does not differentiate from sibling tools that are similarly named 'action' tools for other services, though the service name 'Readwise' provides some distinction.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. No prerequisites mentioned (e.g., needing an API key), and no context for which action to choose based on user intent.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden. It only states it 'gets' data, implying a read operation, but fails to disclose authentication requirements (access_token is in schema but not described), rate limits, error behavior, or whether it returns all posts or paginated results.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise at one sentence, but is too minimal and lacks front-loading of key constraints. It could be more structured to cover parameter usage and output briefly.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 4 parameters, no output schema, and no annotations, this description is incomplete. It does not describe the return format (e.g., profile fields, post structure), pagination, or error responses, leaving an agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning beyond the input schema. With only 25% schema coverage (only 'type' has a description), the description should compensate but does not explain 'access_token', 'username', 'limit', or the effect of different 'type' values.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get a Reddit user profile and posts' clearly states a specific verb and resource. It is distinguishable from sibling tools like reddit_post (single post) and reddit_search (search), but does not explicitly differentiate itself.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as reddit_search or reddit_read. An agent would not know the appropriate context, such as retrieving a user's own posts vs. searching for content.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits, but it only states 'List deploys.' It omits critical details such as read-only nature, authentication requirements, rate limits, pagination, or error handling, failing to adequately inform the agent.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but overly minimal. It earns a 3 because while it is not verbose, it sacrifices necessary detail for brevity.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, and the description fails to disclose any behavioral traits such as authentication requirements, pagination, rate limits, or side effects. The agent lacks critical information about the tool's operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (one sentence), but it sacrifices necessary detail. While it is front-loaded, it fails to include essential context, earning a middle score.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and incomplete parameter documentation, the description is severely inadequate. The agent cannot understand what the tool returns or how to use it properly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain any of the four parameters (shop_domain, limit, api_key, access_token). The agent has no clue about parameter usage or required format.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get collections from a Shopify store,' specifying the verb (get) and resource (collections). It distinguishes from sibling tools like shopify_products or shopify_orders, which operate on different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs. other Shopify tools (e.g., search vs. list). No prerequisites, limitations, or context for use are provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description only says 'Get fulfillments', which implies a read operation but does not disclose any behavioral traits such as authentication requirements, rate limits, pagination behavior, or whether it returns all fulfillments for the order. As no annotations exist, the description carries the full burden, but it fails to add value beyond the name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, making it concise. However, it is so minimal that it sacrifices necessary detail. It is not verbose, but it lacks structure and completeness for a tool with 4 parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters (2 required), no output schema, and sibling Shopify tools, the description is incomplete. It does not clarify the return format (likely a list), the need for authentication (implied by parameters but not stated), or the semantics of inputs. The brief description leaves gaps that could confuse the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, with 4 parameters (shop_domain, order_id, api_key, access_token) lacking descriptions. The description does not explain any parameter (e.g., what shop_domain means, how to provide order_id, or that api_key and access_token are authentication credentials). The agent must rely solely on parameter names, which are ambiguous without context.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'Get fulfillments for a Shopify order.' The verb 'Get' and resource 'fulfillments' are specific, and together with the context of Shopify orders, it distinguishes from sibling tools like shopify_orders (which deals with orders themselves) and shopify_products.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. Sibling tools like shopify_orders or shopify_products exist, but the description does not specify that this tool is for listing fulfillments associated with a specific order, nor does it mention any prerequisites or constraints.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden of behavioral disclosure, but it only states 'Get inventory' without mentioning that it is a read operation, required authentication (though parameters imply it), rate limits, or response format.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words, but it is too brief to be fully useful. It sacrifices completeness for brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the 4 parameters, no annotations, and no output schema, the description is insufficient. It does not explain what 'inventory' entails, how parameters relate, or any conditions for successful use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage, and the description adds no information about parameters beyond their names. For example, 'product_id' is ambiguous and could benefit from explanation, but none is provided.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'inventory for Shopify products', distinguishing it from sibling tools like 'shopify_products' or 'shopify_orders'. However, it could be more specific about what inventory data is returned (e.g., stock levels, variants).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has one parameter and no output schema, so the description should clarify what the returned data represents. It does not. The description is incomplete for an agent trying to decide if this tool meets its needs.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning beyond the input schema. It mentions 'by ID' but the schema already defines league_id as a required string. No additional context about the parameter's format, source, or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and resource ('Sleeper fantasy league') and specifies input method ('by ID'). However, it does not differentiate from sibling tools like sleeper_league_matchups or sleeper_league_rosters, which also relate to leagues.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, no prerequisites, and no context about appropriate scenarios. Simply states the operation without any when-to-use or when-not-to-use advice.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but only says 'Get all NFL players'. It does not disclose whether the list is static, dynamic, or any limitations like rate limits or data size. The behavior is minimally described.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity of the tool (one optional parameter, no output schema), the description is incomplete. It fails to explain the parameter, return value, or any nuances, leaving significant gaps for the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage for the 'sport' parameter, and the tool description does not mention the parameter at all. The agent receives no guidance on what values are valid or how to use it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'all NFL players', which distinguishes it from sibling tools like sleeper_trending_players and sleeper_league_rosters. However, the input schema includes a 'sport' parameter, suggesting it might not be limited to NFL, creating slight ambiguity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool vs alternatives such as tmdb_search_movies or tmdb_now_playing. The description lacks any context about prerequisites or suitable scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations present, and the description does not disclose any behavioral traits. It fails to mention rate limits, authentication (api_key parameter), pagination behavior, or that this is a read operation. The description adds no value beyond the tool name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, making it concise. However, it is too sparse and lacks structure; it does not front-load important details or separate different aspects. It is under-specified rather than concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters, no output schema, and no annotations, the description is severely incomplete. It does not explain the purpose of parameters, return format, or any usage context. The agent would lack critical information to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description provides no explanation for any of the 4 parameters (query, year, page, api_key). It does not clarify what 'year' or 'page' mean or how they affect results. This is a critical gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search for movies on TMDB' clearly states the action (search) and resource (movies) and service (TMDB). It differentiates from siblings like tmdb_search_tv (search TV) and tmdb_movie (single movie). However, it lacks additional context like 'search by keyword' which would improve clarity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as tmdb_movie for a specific movie or tmdb_trending for popular movies. The description does not mention when searching is appropriate or what to expect in return.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description carries full burden. It only says 'Search for venues' without disclosing output format, pagination, rate limits, or authentication details beyond the api_key parameter hinting at it.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, which is efficient but may be too brief for adequate communication. Every word earns its place, but structure is minimal.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and no parameter descriptions, the description is incomplete. An agent lacks sufficient context to effectively use the tool, especially for parameter formatting.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description provides no explanation for any parameter. Parameters like keyword, countryCode, stateCode, and api_key are left entirely to the agent's interpretation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches for venues on Ticketmaster, with a specific verb and resource. However, it does not distinguish this from sibling tools like tm_search_attractions or tm_get_venue.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, no mention of filtering criteria or expected use cases. The description implies usage but lacks explicit context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description bears full responsibility for disclosing behavior. It only states 'Get' (implying read-only), but does not mention auth requirements, rate limits, error states, or any other operational traits. Critical behavioral details are missing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but too brief to convey necessary information. It leverages front-loading but sacrifices completeness; a medium score fits.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given two parameters and a specific domain (Trove), the description is severely incomplete. It lacks context about what a 'work' is, expected output, and usage boundaries. The agent is left to guess.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must clarify parameters. It does not explain what 'id' represents (a Trove work identifier) or the role of 'api_key'. The agent receives no semantic help beyond the schema's basic types.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and resource ('a specific Trove work') and references the required ID parameter. It distinguishes from sibling tools like 'trove_search' and 'trove_newspaper_article', but does not explicitly differentiate between a 'work' and a 'newspaper article', so it loses a point.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, typical use cases, or exclusions. The agent receives no context for decision-making.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, description must disclose behavior. Only states 'Get details' implying read-only, but no mention of authentication, side effects, or response format.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence is concise but sacrifices clarity. Could include more useful information without being verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple get operation with 3 required parameters and no output schema, the description is severely lacking. It does not explain what 'details' are returned or how to use the parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Only 33% of parameters have schema descriptions; description adds no additional meaning to api_key or org. The description does not compensate for the missing parameter info.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the verb 'Get' and resource 'details for a specific Turso database'. This is distinct from siblings like turso_list_databases, though no explicit differentiation is made.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like turso_list_databases. No prerequisites or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must disclose behavioral traits. It does not mention whether the check is read-only, if it consumes the code, or what side effects occur (e.g., marking as verified). Authentication requirements are implicit in the schema but not explained.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (one short sentence) with no wasted words, but it lacks structure and depth. It is appropriately short but borderline under-specified.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 required parameters, no output schema, and no annotations, the description is too minimal. It does not explain the return value (e.g., whether verification succeeded, error messages), leaving the agent without critical information to act on the result.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 20% (only 'code' has a description). The description adds no additional meaning for the other 4 parameters (account_sid, auth_token, service_sid, to) beyond what is in the schema, which is insufficient for such low coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Check' and the resource 'a verification code submitted by a user via Twilio Verify,' distinguishing it from sibling tools like twilio_send_verify. However, it could be more specific about what 'check' entails (e.g., validation status or result).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. For example, it does not mention that this should be used after sending a verification code via twilio_send_verify, nor does it provide any context on prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description only states it lists messages. Lacks details on authentication, rate limits, pagination, or whether it returns all messages or requires filtering.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, very concise but under-specified for a tool with 6 parameters and no output schema.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Missing output schema, no annotations, low param coverage; description does not explain return format, pagination, or filtering behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 17% (only date_sent described). Description adds no explanation for the 6 parameters, such as 'to', 'from', 'page_size'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clear verb ('list') and resource ('SMS messages') with context sent or received on a Twilio account. Does not differentiate from sibling tools like twilio_get_message or twilio_list_calls.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is severely incomplete. It lacks context on authentication (access_token, tenant_id), filtering options (status, contact_id), output expectations (no output schema), and any behavioral notes. With 4 parameters and no annotations, much more detail is required.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning to the 4 parameters (status, contact_id, access_token, tenant_id). With 0% schema description coverage, the agent has no insight into how to use these parameters effectively.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get quotes from Xero' clearly states the action (get) and resource (quotes), distinguishing it from sibling Xero tools like xero_accounts, xero_invoices, etc. However, it lacks any additional detail about the scope or nature of the quotes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., xero_invoices for invoices, xero_reports for reports). There is no mention of prerequisites, authentication context, or scenarios where this tool is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description does not disclose behavioral traits such as authentication requirements (api_key), rate limits, pagination, or default sorting. With no annotations provided, the description should compensate but fails to do so.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, too short to provide necessary context. While concise, it sacrifices completeness, so it is not well-structured for effective tool selection.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is incomplete given the tool's complexity. It does not address key aspects like required authentication (api_key), pagination, result structure, or behavior of optional parameters, making it insufficient for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no parameter information beyond the schema, which already has low description coverage (33%). The tool has 9 parameters and the description does not explain any of them, forcing the agent to rely solely on the incomplete schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches YouTube for videos, channels, or playlists. This verb+resource combination distinguishes it from sibling tools like youtube_get_video, so purpose is clear.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus the many other YouTube tools available. There is no mention of alternatives or exclusions, leaving the agent to infer usage solely from the tool name.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description is minimal with no details about response format, authentication, rate limits, or behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Under-specified single sentence; lacks necessary detail for effective tool usage.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, no parameter descriptions, minimal behavioral context; agent cannot determine what data is returned or how to use the tool properly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%; description does not explain what 'artist' and 'app_id' parameters represent or their expected formats.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clear verb 'Get' and specific resource 'artist profile from Bandsintown', distinct from sibling tools like bandsintown_events and bandsintown_recommended.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives; no exclusions or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description mentions storing a run record and echoing operator context, implying some state mutation, but does not disclose side effects, idempotency, or permission requirements. With no annotations provided, the description carries full responsibility for behavioral clarity and falls short.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is brief (two sentences) but the second sentence is dense and technical ('Chunk 1 stores an in-session run record...'), which may confuse agents. It could be more front-loaded with the core action.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has no output schema and the description does not explain what the tool returns (e.g., a run ID). It also fails to clarify what 'Chunk 1' refers to, leaving important context unexplained. For a 'start run' action, the agent likely needs to know the result to proceed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so each parameter has a description in the schema. The description adds no additional meaning beyond what the schema already provides, such as the purpose of the 'profile' enum or the significance of 'audience' and 'goal'. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description identifies the tool as starting a 'scaffold CopyPass run for AI-generated copy', providing a clear verb and resource. However, the term 'scaffold' and 'Chunk 1' are jargon that may not be immediately clear, and it fails to distinguish this from sibling tools like seopass_run, uxpass_run, or testpass_run, which have similar structures but different domains.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description does not specify appropriate contexts or prerequisites, leaving the agent to infer usage from the name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not convey behavioral traits such as data source details, response format, rate limits, or that it is a read-only operation. The brief statement adds no behavioral context beyond the obvious.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    At 7 words, the description is concise but overly terse. It could include essential details without becoming verbose. The structure is a single sentence, which is acceptable for such a simple tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the low complexity (one parameter, no output schema), the description should at least specify valid region values and response behavior. It fails to provide this, making the tool usage unreliable without external knowledge.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has a single string parameter 'region' with 0% schema description coverage and no enums. The description does not clarify what constitutes a valid region (e.g., continent names, country names? ), leaving the agent with no guidance on parameter values.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', resource 'countries', and filter 'by region'. This distinguishes it from sibling tools like country_by_code, country_by_name, etc., which filter by different criteria.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not specify when to use 'by region' vs other country endpoints, nor any prerequisites or limitations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavioral traits. It fails to mention the requirement for an API key, rate limits, or what specific statistics are returned. The description is too minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, but it sacrifices necessary detail for brevity. Important context is missing, making it under-specified rather than concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 5 parameters, no output schema, and no annotations, the description is completely inadequate. It does not explain what market statistics are, how to structure parameters, or what the response contains.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description should clarify parameters. It does not mention any parameter, leaving the agent with no guidance on how to use suburb, state, postcode, propertyCategory, or api_key.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'property market statistics' for a specific scope 'Australian suburb'. It distinguishes from sibling tools like domain_get_property (property details) and domain_search_listings (listings search) by focusing on statistics.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like domain_get_property or domain_search_listings. The description lacks context such as prerequisites or typical use cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description only says 'Get esports matches'. It does not disclose any behavioral traits such as pagination, rate limits, authentication requirements, or what data is returned.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise. However, it is too brief and does not provide sufficient information, making it under-specified rather than efficiently complete.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 5 parameters, no output schema, and no annotations, the description is severely lacking. It fails to explain pagination, authentication, or how to filter matches (e.g., status values). The tool is incomplete for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 40% (2 of 5 parameters have descriptions). The tool's description adds no additional meaning to parameters, leaving the 3 undocumented parameters (page, per_page, api_key) without context.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get esports matches from PandaScore', which is a specific verb and resource. It distinguishes from sibling tools like esports_players or esports_teams, but lacks any scope or filtering details.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like esports_get_match (singular). No context on preferred use cases, required parameters, or prerequisites.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Simple tool, but no output schema or annotations. The description should at least mention the return type or any filtering options. It feels incomplete for an agent to use safely.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to parameters beyond their names. For example, it doesn't explain what event_id refers to or if api_key is needed for authentication.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'Get' and resource 'attendees', clearly indicating the tool retrieves attendee data for an Eventbrite event. It distinguishes well from sibling Eventbrite tools like get_event or create_event.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence but at the expense of necessary detail. It is under-specified, essentially a tautology of the tool name with added source.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 3 parameters (1 required), no output schema, and no param descriptions, the description fails to provide enough context for correct invocation. It omits even basic parameter purpose.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% and description explains none of the three parameters. Even the required 'date' parameter is not mentioned, forcing the agent to infer from schema definitions alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'historical forex rates' with a source 'Open Exchange Rates'. It distinguishes itself from siblings like 'forex_latest' by explicitly specifying 'historical'.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavior, but it only states 'Get NASA Mars rover photos.' No mention of required authentication (api_key), pagination, rate limits, or any side effects. This is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at one sentence. While it lacks detail, it is front-loaded with the core purpose. However, brevity here sacrifices necessary information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters, no output schema, and no annotations, the description is far from complete. It does not explain key concepts like 'sol' or 'camera', nor does it address authentication or response format.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is low (20%), and the description adds no parameter information. The schema description for 'rover' is incomplete (missing 'perseverance'), and the tool description fails to clarify param usage or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get NASA Mars rover photos' clearly identifies the verb (Get) and resource (NASA Mars rover photos), distinguishing it from sibling NASA tools like nasa_apod or nasa_asteroids. However, it does not specify which rovers or photo types, leaving some ambiguity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as other NASA image tools. The description lacks context about prerequisites or typical use cases.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise (3 words), but at the expense of utility. The sentence is front-loaded but too sparse; could be expanded without harming brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 6 parameters, no output schema, and no annotations, this description is severely incomplete. It fails to provide any operational context, making it hard for an agent to use effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. The description does not explain or add context to any of the 6 parameters, leaving the agent to infer from names alone. Fails to compensate for low schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool queries QuickBooks Online payments, using a specific verb and resource. It implicitly distinguishes from sibling QuickBooks tools by targeting 'payments', but does not explicitly differentiate.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., quickbooks_invoices, quickbooks_customers). No context on prerequisites or filtering options.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 9 parameters, no schema descriptions, no output schema, and no annotations, the description is drastically incomplete. It fails to explain how different actions map to parameters, what each action does, or what the response contains, making it nearly unusable for an AI agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%, meaning no parameter descriptions exist. The description does not explain how parameters like channel, text, thread_ts, query, emoji, timestamp, or limit relate to each action, leaving the agent to infer meaning from names alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states the tool performs a Slack action and lists the specific sub-actions (slack_send, slack_read, etc.), making the purpose clear. It distinguishes itself as the only Slack tool among siblings, but it does not specify a single verb+resource.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. There are no sibling Slack tools, but the description does not explain under what circumstances to use each sub-action or provide any context on best use.

    The schema has 0% description coverage, and the description does not explain any parameters (e.g., format of location or timestamps). This leaves the agent without semantic guidance.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'get' and the resource 'historical weather data', and implicitly distinguishes from sibling tools 'tomorrow_forecast' and 'tomorrow_realtime' by specifying 'historical'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidance is provided. The description does not mention when to use this tool versus weather_current, weather_forecast, or the sibling tomorrow tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Without annotations, the description fails to disclose behavioral traits such as side effects, error handling, or authentication requirements. It only implies mutation via 'Update'.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with a single sentence, but it lacks structure and omits critical details, making it insufficiently informative despite its brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of an output schema, annotations, and the complexity of a mutation tool, the description is severely incomplete, failing to explain return values, error cases, or prerequisites.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema covers only two of five parameters with descriptions, and the tool description adds no extra meaning beyond the schema, leaving key parameters like board_id and api_key unexplained.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Update) and resource (column value on a Monday.com item), distinguishing it from sibling tools like create_monday_item and list_monday_items.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidance is provided; the description does not indicate when to use this tool over alternatives or mention prerequisites like needing the column ID from board metadata.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, placing full burden on the description. The description only states 'List all topics', but does not confirm it is read-only, disclose permissions, rate limits, or behavior on empty clusters. This is insufficient for safe invocation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, efficiently stating purpose. However, it omits essential details; every sentence should earn its place, and while concise, it does not add value beyond purpose. Still, it is appropriately brief.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 3 required parameters, no output schema, and no annotations, the description fails to provide adequate context. The agent lacks understanding of inputs, outputs, and operational behavior, making the tool nearly unusable.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning the input schema only provides names and types. The description does not explain any parameters (api_key, email, cluster_id), leaving their roles and formats entirely ambiguous.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'List all topics in an Upstash Kafka cluster', which specifies the verb (list), resource (topics), and scope (cluster). Among sibling tools like upstash_kafka_produce, this uniquely identifies its purpose.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. An agent has no context for deciding between this and other Upstash tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits such as rate limits, permissions, data freshness, or what the report contains. It merely restates the function implied by the name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise, consisting of one short sentence. However, this conciseness comes at the cost of missing necessary details, earning a middle score.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity of the tool, the description is still incomplete. It lacks context about what a report entails, output, or any usage conditions. The complete absence of parameter descriptions and behavioral info makes it inadequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage. The description does not explain the 'url' or 'api_key' parameters beyond implying the URL. No meaning is added beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get a VirusTotal report for a URL.' clearly states the action (Get) and resource (VirusTotal report for a URL). It is specific and distinguishes from sibling tools like virustotal_scan_url or virustotal_scan_domain.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus siblings like virustotal_scan_url. It lacks context on prerequisites, such as whether the URL must be submitted first, or any alternatives.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose side effects and operational constraints. It only states the actions without explaining that 'create' modifies data or any authentication requirements beyond schema fields.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise at 6 words, but overly terse for a complex tool with 12 parameters and 3 actions. Lacks structure; no separation of concerns.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Severely incomplete given 12 parameters, nested objects (order), no output schema, and no annotations. Fails to explain return format, error handling, pagination, or creation requirements.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Description adds no value beyond the input schema. Schema coverage is 50%, and parameters like store_url, consumer_key are unexplained. The action enum is defined in schema but not elaborated.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool works with WooCommerce orders and the three actions (list, get, create). It distinguishes WooCommerce orders from sibling tools like woo_customers by resource type, though no differentiation from order tools of other platforms.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like woo_products or shopify_orders. Missing recommendations for action selection or prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description bears full responsibility for transparency. It only states the basic function without disclosing behavior such as read-only nature, authentication requirements (implied by schema), pagination, or error handling.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 12 parameters, no output schema, and no annotations, the description is grossly incomplete. It omits essential context about actions, required parameters, optional filters, and expected results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no information about parameters beyond what the input schema already provides. With 50% schema description coverage, the description should compensate but fails to clarify the meaning or usage of key parameters like action, id, or pagination controls.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description "List or get WooCommerce products" clearly indicates the action (list or get) and the resource (products). However, it does not distinguish itself from sibling tools like woo_customers or woo_orders, which could lead to confusion.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 4 parameters with 0% schema description coverage. The description adds no meaning to the parameters (e.g., what 'from_postcode' and 'to_postcode' expect, what 'service_code' options are). The agent must guess or rely on external knowledge.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Get Australia Post estimated delivery times.' The verb 'Get' and resource 'estimated delivery times' are specific. While it doesn't explicitly differentiate from siblings, the sibling names (e.g., 'auspost_get_postcode', 'auspost_track_parcel') imply distinct functions, so purpose is reasonably clear.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as email_search or email_get. There is no context about prerequisites, filters, or exclusion criteria. The description provides no usage direction.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description fails to disclose behavioral traits like data freshness, pagination, or authentication requirements. The description carries the full burden for transparency but does not deliver.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that is front-loaded with the key purpose. No wasted words, though additional details could be added without harming conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of output schema and parameter descriptions, the description should provide more context about output format and parameter usage. It lacks completeness for a tool with two user-adjustable parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning the parameters 'sport' and 'limit' have no descriptions in the schema. The description does not mention or clarify parameters, failing to compensate for the missing schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Get) and resource (ESPN sports news), and the tool name distinguishes it from sibling tools like espn_mlb_scores which focus on scores. However, it could be more specific about what 'news' entails (e.g., headlines, articles).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as when to use espn_team_info or league-specific score tools. No exclusions or context are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It fails to disclose any behavioral traits such as return format, pagination, rate limits, or authentication needs. The simple statement 'Search esports teams' provides no transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise and front-loaded, but it omits necessary details for effective usage. Acceptable structure for a simple tool, but could be expanded helpfully without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 3 parameters, no output schema, and no annotations, the description is critically incomplete. It does not explain return format, parameter constraints, or any behavioral context needed for an agent to invoke it correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description should explain the parameters. It does not. While 'game' and 'search' are somewhat self-explanatory, the description adds no value beyond the parameter names, failing to compensate for missing schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Search'), resource ('esports teams'), and platform ('PandaScore'). Among sibling tools like esports_get_match, esports_players, etc., this tool is distinctly about teams, so differentiation is clear.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool over alternatives. The description does not mention what the 'game' or 'search' parameters should contain, nor does it compare with esports_players or other sibling tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description lacks behavioral details such as whether the tool returns a list or single tournament, authentication requirements, or rate limits. The description is too minimal to inform the agent about side effects or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very short, which aids conciseness, but it sacrifices necessary detail. It is not verbose, yet it fails to provide sufficient information for effective tool use.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema, no parameter explanations, and the presence of sibling tools for esports, the description is incomplete. It does not provide enough context for the agent to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain the parameters (game, status, api_key). No valid values, required status, or usage hints are given, leaving the agent to guess their meaning.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get'), resource ('esports tournaments'), and source ('from PandaScore'). However, it does not differentiate from sibling tools like 'esports_matches' or 'esports_get_match', which could cause confusion.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description does not mention context, prerequisites, or exclusion cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden of behavioral disclosure. It describes a read operation but does not specify returned fields, rate limits, authentication setup (api_key purpose), or any side effects. The minimal 'Get details' leaves significant behavioral ambiguity.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, avoiding unnecessary words. However, it is too brief to be helpful, omitting critical details that would require expansion.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the two parameters (one undocumented), no output schema, and sibling tools, the description is incomplete. It does not explain the output format, differentiate shop_id types, or reference related endpoints, leaving significant gaps for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (shop_id described). The tool description repeats that shop_id is a 'shop ID or numeric ID', adding no extra meaning. The api_key parameter has no guidance on origin or format, and the description fails to clarify that shop_id can accept both numeric and string (shop name) values.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get details' and the resource 'Etsy shop', and specifies an identifier ('shop ID or numeric ID'). It distinguishes from sibling tools like 'etsy_search_shops' (which searches) and 'etsy_get_listings' (which gets listings), though it does not explicitly name them.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as 'etsy_search_shops' or 'etsy_get_shop_listings'. It does not mention prerequisites, context, or scenarios where this tool is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must fully disclose behavioral traits. It only mentions searching by name, ignoring authentication (api_key), pagination (limit/offset), response format, rate limits, or whether results are exact matches or fuzzy. This is insufficient for a search tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, which is efficient. However, it omits critical information, making it under-specified rather than appropriately brief. It could be improved with more structure without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations, no output schema, and 4 parameters with only 25% schema coverage, the description is incomplete. It lacks return value description, prerequisites, and any behavioral context necessary for a search tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 25% (only 'shop_name' has a description). The description adds no parameter details beyond 'by name', leaving 'api_key', 'limit', and 'offset' unexplained. The low coverage requires compensation, which is absent.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Search for Etsy shops by name,' specifying the verb (search) and resource (shops). However, it doesn't differentiate from sibling tools like 'etsy_search_listings' or 'etsy_get_shop', which have distinct purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., 'etsy_get_shop' for a known shop). There are no explicit contexts, exclusions, or references to other tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only states that it creates an event, omitting essential details like authentication requirements, side effects, or constraints. The api_key parameter hints at auth, but the description does not confirm it.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at 4 words, but this comes at the cost of informativeness. It is front-loaded but sacrifices necessary detail, making it minimally adequate.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (7 parameters, no output schema, no annotations), the description is severely incomplete. It lacks context on how to use the parameters, what the tool returns, and any success/failure conditions. An AI agent would struggle to invoke this tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no parameter-level information. The tool has 7 parameters, including api_key and organizer_id, but their purposes are not explained. The description fails to compensate for the schema's lack of documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Create an event on Eventbrite,' which is a specific verb and resource. It distinguishes this tool from sibling tools like eventbrite_get_event or eventbrite_search_events by action and resource.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus other Eventbrite tools. It does not mention alternatives, prerequisites, or context, leaving the AI agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so the description must carry the behavioral burden. It only states data retrieval, without disclosing response format, authentication needs, rate limits, or any other behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, which is concise but overly brief. It front-loads the action but lacks structure or additional clarifying details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of output schema and annotations, and the presence of many sibling F1 tools, the description is too sparse. It does not inform the agent about expected return data, parameter usage, or the tool's role within the ecosystem.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. The description does not explain what 'session_key' or 'driver_number' mean, how to obtain them, or that driver_number is optional. No value added beyond the schema's property names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'pit stop data' from 'OpenF1'. It distinguishes from sibling F1 tools by specifying pit stops, but lacks explicit differentiation from similar data retrieval tools like f1_laps.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like f1_laps or f1_car_data. The description does not provide context or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must convey behavior, but it only states 'get data'. It does not disclose mutation, data freshness, error handling, or side effects. The agent cannot infer safety or reliability from this minimal text.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, efficiently front-loaded with the action verb. However, it is under-specified for the tool's complexity, sacrificing completeness for brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of an output schema and the presence of multiple F1 siblings, the description fails to specify what data is returned or how to interpret results. The agent cannot assess if this tool meets its needs without additional detail.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% and the description does not explain what 'session_key' or 'driver_number' represent. The parameter names offer weak hints, but no meaning is added beyond the schema's bare structure, failing to clarify how to query position data.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'Get' and resource 'Formula 1 position data', clearly indicating data retrieval. However, it does not distinguish from sibling F1 tools like f1_laps or f1_drivers, leaving ambiguity about what 'position data' entails (e.g., driver standings, track positions).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. The AI agent receives no context to choose it over sibling tools for specific F1 data needs.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description must convey behavioral traits. It states a conversion action but omits key details like required permissions, rate limits, data freshness, or whether the operation is read-only. The minimal disclosure leaves the agent without critical safety and behavior context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence conveying the core action. No redundant words. It is optimally concise for a simple tool definition.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and four undocumented parameters, the description is grossly incomplete. It fails to describe return format, error conditions, or handling of optional api_key. The tool's complexity is not addressed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the four parameters (from, to, amount, api_key). The agent gets no information about formats, allowed values, or parameter roles beyond the schema's type and required fields.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool converts a currency amount and names the data source (Open Exchange Rates). It uses a specific verb and resource, but does not differentiate from sibling tools like forex_rate which also performs conversion. The purpose is apparent but not uniquely distinguished.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool instead of alternatives such as forex_rate or forex_currencies. There is no mention of prerequisites, limitations, or contextual cues for selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It implies a read operation but provides no details on rate limits, authentication (beyond api_key parameter), error behavior, or response nature. Insufficient for safe agent usage.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 3 parameters, no output schema, and no annotations, the description is incomplete. It lacks return value semantics, examples, or usage advice, making it inadequate for effective agent invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description adds no meaning beyond the parameter names (query, ll, api_key). Does not explain that 'query' is the search string, 'll' is lat/long, or that api_key is required.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Autocomplete a Foursquare place search' clearly states the verb and resource. It distinguishes from sibling tools like foursquare_search_places (full search) and foursquare_get_place (detail retrieval), though it does not elaborate on what 'autocomplete' entails.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use autocomplete versus alternatives like foursquare_search_places or yelp_autocomplete. The description offers no context for proper invocation.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple, but without annotations or output schema, the description is insufficient. It does not specify what 'details' includes, nor does it explain the access_token parameter. The agent needs more context to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (only video_id has a description). The description does not add any meaning beyond the schema for video_id, and it completely ignores access_token, which lacks a description in the schema as well. This leaves a crucial parameter undefined.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (get details), resource (TikTok video), and identifier (by ID). It distinguishes from sibling tools like list_tiktok_videos which lists multiple videos, and get_tiktok_user which is a different resource.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as search or list tools. There is no mention of prerequisites or when not to use it. The description relies on the name and schema to imply usage, but fails to provide explicit context.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits such as authentication requirements (api_key is optional in schema but likely needed), rate limits, or data freshness.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 8 words, very concise and front-loaded. However, it may be too minimal, sacrificing completeness for brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description fails to inform about the return value or format. It is incomplete for an AI agent to understand the tool's full behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning beyond the parameter names. It does not clarify the format, constraints, or purpose of 'domain' or 'api_key'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('Get'), resource ('email information for a domain'), and source ('from Hunter.io'). However, it does not specify what type of email information (e.g., email addresses, patterns, count) or differentiate from sibling tools like hunter_find_email or hunter_verify_email.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no indication of prerequisites, context, or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden of behavioral disclosure. It only implies a read operation ('look up') but does not state safety, rate limits, data sources, or accuracy. Critical behavioral traits are omitted.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with 8 words is concise, but the description is under-specified. It sacrifices essential detail for brevity, making it minimally adequate.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of annotations and output schema, the description should provide more context about return values, data format, or limitations. It fails to make the tool self-contained, leaving the agent uninformed about outputs and usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning beyond parameter names. It does not explain that 'ip' is a standard IP address or that 'api_key' is optional. The purpose of the optional key is unclear.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('look up') and resource ('geolocation for an IP address'), making the basic purpose obvious. However, it does not distinguish from the sibling tool 'ip_batch' which likely performs batch lookups, missing an opportunity to clarify scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like 'ip_batch' or other lookup tools. It also lacks any prerequisites or context about required authentication (e.g., API key) or use cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as idempotency, side effects, or rate limits. It merely says 'Perform' without indicating which actions are read-only versus write operations. An agent cannot infer safety or cost implications from this description.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is short (one sentence) but poorly structured. The list of actions is run together, making it harder to parse. It could be more effective with bullet points or clearer separation. However, it avoids unnecessary verbosity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (8 parameters, no schema descriptions, no output schema), the description is far from complete. It fails to explain how to use the parameters, what each action expects as input, or what the response looks like. The agent lacks critical context to invoke the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate for parameter meanings. However, it only lists action names without explaining the role of 'status', 'id', 'q', 'acct', or other parameters. The agent cannot determine which parameters are needed for each action from the description alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool performs Mastodon actions and lists nine specific action types. While it doesn't explicitly frame it as a router/dispatcher, the enumeration of actions provides adequate purpose clarity. However, it lacks a verb+resource structure that distinguishes it from sibling tools like bluesky_action.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. With many sibling tools (e.g., bluesky_action, slack_action), the description should indicate scenarios where this dispatcher is appropriate or mention that dedicated tools might be preferable for single actions. The description offers no such context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for disclosing behavioral traits. It only states 'Get data' without mentioning that the tool requires a date range and API key, is read-only, or any rate limits or error behaviors.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that is front-loaded with the tool's purpose. It avoids unnecessary words but could benefit from slight expansion for clarity without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has three parameters and no output schema, the description is too sparse. It does not explain how to use the parameters, what kind of data is returned, or any constraints (e.g., date range limits). The agent lacks sufficient context to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning no parameter descriptions exist in the schema. The description adds no information about the purpose or format of the three parameters (start_date, end_date, api_key), leaving the agent to infer from names alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'NASA Near Earth Object (asteroid) data', which differentiates it from sibling NASA tools like apod, earth_imagery, epic, and mars_photos. However, it lacks specificity about the data scope beyond 'asteroid data'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of preconditions, context, or scenarios where this tool is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description does not disclose any behavioral traits beyond retrieval. With no annotations, it fails to explain what EPIC imagery entails, authentication needs, or potential side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise at one sentence, but it omits critical information, making it under-specified rather than optimally brief.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with two parameters, no output schema, and no annotations, the description is severely incomplete. It does not explain what EPIC is, how parameters work, or what the response contains.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description adds no meaning to the parameters 'date' and 'api_key'. Their purpose and format are entirely undocumented.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the specific resource 'NASA EPIC Earth imagery', effectively distinguishing it from sibling tools like nasa_apod and nasa_mars_photos.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, nor any mention of prerequisites or required parameters. The description provides no context for invocation decisions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but only says 'Get available news sources'. It doesn't disclose any behavioral aspects like read-only nature, rate limits, or authentication requirements.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence. It is concise but may be too sparse; however, it earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the 4 optional parameters, lack of output schema, and no annotations, the description is insufficient. It doesn't explain response format, default behavior, or how filters work.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the parameters (country, category, language, api_key). The agent has to infer from names alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'available news sources', making the tool's purpose unambiguous. It distinguishes from sibling tools like news_search and news_top_headlines which deal with articles.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., searching articles). The description lacks context for the agent to decide between tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description does not disclose any behavioral traits such as authentication requirements, rate limits, or whether the operation is read-only. Since annotations are absent, the description carries the full burden, yet it provides minimal insight. The agent might be surprised by the required api_key parameter.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no excess words. However, it may be too concise to be helpful, lacking structure or detailed information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has no output schema, and the description does not specify what the response contains (e.g., list of model IDs, names, or metadata). The agent is left without key context needed to use the output effectively. For a list tool, this is a significant gap.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The only parameter is 'api_key' (required), and the schema has 0% description coverage. The description does not explain the parameter's purpose, format, or constraints. While the parameter name is self-explanatory, the description adds no value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List all OpenAI models available to the account.' clearly specifies the action (list) and the resource (OpenAI models). It distinguishes the scope (all models available to the account) from potential siblings that list models for other providers. However, it does not differentiate from other list_models tools except by naming OpenAI, which is already in the name.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., openai_chat_completion) or when not to use it. There is no mention of prerequisites or context. The agent must infer usage from the name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully disclose behavioral traits. It only states 'List', implying a read operation, but does not mention rate limits, pagination behavior, response structure, or any side effects. The addition of 'date range' is inaccurate as no such parameter exists in the schema.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it includes an inaccuracy (date range). While front-loaded with the core operation, the inaccuracy reduces its effectiveness. It could be improved with a clearer, error-free structure.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 5 parameters, no output schema, and no annotations, the description is insufficient. It does not explain what the response contains (list of incidents), how pagination works (despite limit/offset in schema), or that api_key is required. The inaccuracy on date range further undermines completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with parameter descriptions. The description adds value by listing status values explicitly, but it also mentions a 'date range' filter that does not exist in the schema (no date parameters), causing confusion. It does not explain the purpose of 'limit' and 'offset' for pagination.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'List PagerDuty incidents' with a specific verb and resource. It lists available filters, distinguishing it from sibling tools like pagerduty_get_incident (single incident) or pagerduty_acknowledge_incident (action). However, it does not explicitly mention that no filters return all incidents, leaving slight ambiguity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus siblings (e.g., get_incident for a single incident, resolve_incident for resolution). The description does not mention prerequisites, context, or alternatives, forcing the agent to infer usage from names alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description falls short. It implies a read operation but does not disclose behavioral traits such as authentication requirements, rate limits, or the nature of the data returned.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise with one sentence, but it lacks structure. While brevity is good, it should still provide essential context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It fails to explain the output, prerequisites (like obtaining an access_token), or how this tool fits into the Plaid workflow.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage, and the tool description adds no meaning beyond parameter names. Although parameter names are self-explanatory, the description should elaborate on their purpose or usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'identity information for accounts linked via Plaid', which is specific. However, it does not differentiate from sibling tools like plaid_accounts or plaid_balances, which also retrieve account-related data.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behavioral traits like authentication requirements or limits. It only says 'get episodes' without mentioning that api_key and api_secret may be needed for Podcast Index authentication, or that the response might be paginated. This is a significant gap for a tool requiring credentials.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, which is concise. However, it is too brief to cover necessary details for a tool with 4 parameters and no annotations, resulting in under-specification rather than concise completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of 4 parameters, no annotations, and no output schema, the description should explain how to obtain the podcast ID, the role of max, and authentication requirements. It currently lacks this essential context, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description carries full burden. It provides minimal context (only implies id is a podcast identifier). The meaning of max, api_key, and api_secret is left entirely to inference, which is insufficient for correct invocation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (get episodes) and the resource (podcast from Podcast Index), specifying the source. However, it does not differentiate from sibling tools like podcast_recent_episodes or podcast_search_episodes, which could cause confusion about when to use this specific tool.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidelines are provided. The description does not indicate when to use this tool vs alternatives such as podcast_search_episodes or podcast_by_feed_url, nor does it mention prerequisites like needing a podcast ID from a previous search.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations present, the description carries full responsibility for behavioral disclosure. It fails to mention whether the operation is read-only, any rate limits, authentication requirements (api_key parameter is optional but unexplained), or what the response contains. The lack of any behavioral traits beyond the basic action leaves the agent underinformed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise, consisting of a single sentence. While conciseness is generally positive, in this case it sacrifices necessary detail, making it feel under-specified rather than efficiently informative.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has three parameters, no output schema, and no annotations, the description should offer more context about the return format, parameter meanings, and how this tool fits into the broader PTV set. It does not, leaving significant gaps that an agent would need to infer or guess.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the parameters. While route_id and route_type are somewhat self-explanatory, route_type's numeric values (e.g., PTV types) remain ambiguous. The api_key parameter is not described at all. The description provides no value beyond the parameter names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('get') and the resource ('stops on a PTV route'), making the purpose understandable. However, it does not differentiate from sibling tools like ptv_departures or ptv_search, which could also involve stops or routes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, nor does it explain what route_type values mean (e.g., train vs tram) or mention any prerequisites like needing an API key. The description offers no contextual usage hints.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description fails to disclose behavioral traits like error handling for invalid receipts, rate limits, or whether the tool is read-only. The name implies a read operation, but no guarantees are made.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Very concise single sentence, but this comes at the expense of missing important details about usage and behavior.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of an output schema, the description should hint at the response format (e.g., acknowledgment status per user). No differentiation from sibling tools is provided, and the tool's role in the notification lifecycle is unclear.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 50% (only 'receipt' has a description). The description does not explain 'app_token' beyond the schema, and 'receipt' description merely restates the schema. No additional parameter semantics are added.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets acknowledgment status for emergency Pushover notifications. The verb 'Get' and resource 'acknowledgment status' are specific, and it distinguishes from sibling tools like pushover_send_notification.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as pushover_cancel_emergency or pushover_validate_user. No prerequisites mentioned (e.g., must have a receipt token from an emergency notification).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; the description offers no behavioral traits such as auth requirements, rate limits, or error handling. Completely reliant on minimal text.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, 8 words—efficient and front-loaded. However, could include a brief note about token requirement without harming conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a list tool with no output schema, the description should indicate what the response contains (e.g., sound names, IDs). It does not, leaving the agent uninformed about the return values.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain the purpose of 'app_token' or its role. No added value beyond the raw schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the verb 'list' and the resource 'all available notification sounds' in the context of Pushover. Distinguishes from siblings like pushover_send_notification or pushover_cancel_emergency.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, no prerequisites or context provided. The description assumes prior knowledge.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It does not disclose important behavioral traits such as pagination behavior, rate limiting, required authentication (though access_token parameter exists), or what constitutes valid query syntax. The single sentence offers minimal insight into tool behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is compact but lacks any structure. While it avoids verbosity, it does not add additional context or break information into digestible parts. It is average in conciseness given the tool's complexity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 6 parameters, no output schema, and no annotations, the description is severely incomplete. It does not explain the query language for the 'where' parameter, the default limit/offset behavior, or the effect of sandbox mode. The agent would struggle to use this tool correctly without external documentation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning no parameter descriptions exist in the input schema. The tool has 6 parameters (including required access_token and realm_id, plus where, limit, offset, sandbox), but the description adds no meaning to any of them. The agent must infer semantics solely from names, which is insufficient for a query tool.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses 'Query QuickBooks Online items (products and services)', which clearly specifies a verb and resource. It distinguishes from sibling tools like quickbooks_customers by naming the specific resource type (items) and clarifying it covers both products and services.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool instead of alternatives. There is no mention of prerequisites, filtering contexts, or when the query parameter syntax would be appropriate. The description simply states what it does without usage direction.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description only states the action without detailing behavioral aspects such as error handling, rate limits, or permission requirements beyond the schema.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise but lacks structure; it is a single sentence that provides minimal information without further context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of annotations, output schema, and parameter details, the description is insufficient for an agent to understand how to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage and no additional explanation in the description, the meaning of parameters like 'access_token' (e.g., Reddit OAuth token) and 'parent_id' (e.g., fullname format) is unclear.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Post a comment on Reddit.' clearly states the action (post) and resource (comment), but does not distinguish from sibling tool 'reddit_post', which likely posts a thread. This could cause confusion.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like 'reddit_post', nor any prerequisites or context for usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as error handling, authentication requirements, rate limits, or what happens if the model is not found. It only states the action, not how it behaves.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and 3 required parameters, the description is incomplete. It does not explain the return format, error scenarios, or any context about the Replicate platform that would help an agent use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 33% (owner has a description). The tool description does not add any meaning beyond the schema; it does not explain api_token or model_name parameters. For a 3-parameter tool with low schema coverage, the description should compensate but fails to do so.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it gets details and latest version for a Replicate model, specifying the verb 'Get' and resource 'model details and latest version'. However, it does not explicitly differentiate from sibling tool 'replicate_list_models', which likely lists all models.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like replicate_list_models or replicate_create_prediction. The description lacks contextual clues about prerequisites or typical use cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description must carry the burden. It mentions retrieving 'status and output' but does not disclose whether it is read-only, error conditions, or any authentication requirements beyond the schema.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple retrieval tool with two required parameters and no output schema, the description minimally covers what it does. It lacks context about prerequisites (e.g., prediction_id from create_prediction) and output format, but is somewhat complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to parameters. It does not explain api_token or prediction_id, such as how to obtain them or their formats.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get the status and output of a Replicate prediction,' specifying the verb (Get) and resource (prediction). It distinguishes from siblings like replicate_create_prediction and replicate_list_predictions, though 'output' is somewhat vague.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention that it should be used after creating a prediction or that it is for individual predictions rather than listing.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but only states a generic search. No disclosure of rate limits, authentication requirements, or what happens with optional parameters like status or api_key.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence is concise but omits necessary details about parameters and behavior. Conciseness should not come at the cost of completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 3 parameters, no output schema, and no annotations, the description is inadequate. It lacks return format, pagination, error handling, and usage context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. The description does not describe any parameters, leaving query, status, and api_key with no additional meaning beyond their types.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (Search), the resource (Australian patents), and the source (IP Australia). It effectively distinguishes this tool from other search tools like search_trademarks.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like search_trademarks. No exclusions, prerequisites, or context provided.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description only states 'Get a SeatGeek event by ID.' It does not disclose whether the operation is read-only, authentication requirements (though api_key is in schema), rate limits, or error behavior. Minimal disclosure for a tool with no annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, short sentence, which is concise but lacks critical information. It is not overly verbose, but the brevity sacrifices completeness, making it minimally acceptable.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 2 parameters, no output schema, and no annotations, the description is extremely incomplete. It fails to explain what the event data contains, required authentication, or how to handle errors. The agent would be forced to guess or infer from the schema alone.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description provides no explanation of parameters. The id and api_key parameters are not described; the agent receives no guidance on what values to provide or their purpose.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (Get), resource (SeatGeek event), and method (by ID). It distinguishes from sibling tools like seatgeek_search_events, seatgeek_get_performer, and seatgeek_get_venue by specifying direct retrieval by ID.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidance is provided. The description does not mention when to use this tool vs. alternatives, prerequisites, or scenarios. For example, it does not indicate that search tools should be used when the ID is unknown.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Without annotations, the description bears full responsibility for behavioral disclosure. It implies a read operation but fails to mention authentication, rate limits, or response structure. The agent receives no safety or side-effect information.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that conveys the core purpose without redundancy. However, it may be too brief for a tool with undocumented parameters.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description must fully disclose behavioral traits. It only says 'Get matchups' with no information about rate limits, authentication, error handling, or whether the operation is read-only. This is a significant gap.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence that efficiently captures the tool's purpose. It avoids redundancy but could benefit from slight expansion without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity and lack of output schema, the description is too minimal. It fails to mention return format, error cases, or limitations, leaving the agent without essential context for usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has two parameters (league_id, week) with 0% schema description coverage. The description adds no additional meaning or context about these parameters (e.g., format, constraints, or how matchups are defined).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the action ('get matchups'), the resource ('Sleeper fantasy league'), and the scope ('week'). This clearly identifies the tool's purpose and distinguishes it from sibling tools like sleeper_league (league info) and sleeper_league_rosters (rosters).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. Sibling tools for other Sleeper operations exist (e.g., sleeper_league, sleeper_players), but the description does not help the agent decide which tool to invoke.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits like API key requirement, read vs. write operations, rate limits, or side effects. It only lists actions, omitting all such details, leaving the agent unaware of important behavioral constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise at one sentence, but it lacks structure and detail. It front-loads the purpose but sacrifices completeness, resulting in an underspecified definition that requires the agent to infer too much.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (multi-action, 7 parameters, no output schema), the description is woefully incomplete. It does not explain return values, authentication, or how parameters relate to actions, leaving the agent without essential context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds value only for the 'action' parameter by listing the allowed values. For the other 6 parameters (api_key, group_id, description, cost, currency_code, users), the schema has 0% coverage, and the description offers no additional meaning, forcing the agent to guess their usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it performs Splitwise actions and lists the five possible actions (get_groups, get_expenses, etc.), so the verb and resource are clear. However, it does not distinguish the purpose of each action, leaving the agent to infer from the action names alone.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool vs. alternatives or which action to choose in different scenarios. The description lacks any context for decision-making, such as prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden of behavioral disclosure. It only states 'search' without mentioning pagination (cursor parameter), result limits, required authentication (access_token), or the scope of search (e.g., which object types are searched). Critical behavioral traits are missing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no fluff, but it could provide more useful information without increasing length significantly. It is concise but overly minimal.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 5 parameters, no output schema, and no annotations, the description is inadequate. It does not explain pagination, default object types, or result format. A more complete description is needed for an agent to invoke the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 40% (only text_filter and object_types have descriptions). The description adds no value beyond what the schema already provides. It does not explain the roles of access_token, limit, or cursor, which remain undocumented. Since coverage is below 50%, the description should compensate but fails to do so.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search Square catalog objects by text' clearly states the verb (Search) and resource (Square catalog objects), but it does not differentiate from the sibling tool 'square_catalog_list', which likely also lists catalog objects. The purpose is clear but lacks distinction.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    There is no guidance on when to use this tool versus alternatives like square_catalog_list. No context is provided about prerequisites, typical use cases, or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden for behavioral disclosure. It does not mention rate limits, API key requirements, error handling, or latency, which are important for a real-time data tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, brief sentence (8 words) that efficiently communicates the core purpose. However, it may be too terse given the lack of additional context from other fields.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of an output schema and the presence of many sibling tools, the description is insufficient. It does not specify return values, error behavior, or how to handle the optional API key, leaving the agent with minimal context to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage, and the tool description does not explain the meaning or format of the 'symbol' and 'api_key' parameters, leaving the agent with no guidance beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (get), resource (real-time stock quote), and data source (Alpha Vantage), but does not differentiate it from sibling tools like stock_daily or stock_intraday, which may also provide similar data.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, such as other stock-related tools or financial data tools. The description lacks explicit context or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It only states 'List or create Stripe charges' without mentioning authentication requirements, default action, idempotency, or any side effects. This is insufficient for an agent to understand the tool's behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise (one sentence), but it sacrifices necessary detail. It is not overly verbose, but the brevity limits its usefulness. A score of 3 reflects adequate conciseness with room for improvement.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (9 parameters, two distinct actions), the description is too sparse. It does not explain how to use 'list' versus 'create' or the required parameters for each action. No output schema is provided, increasing the need for descriptive completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 44%, but the description adds no parameter-level information. Some parameters like 'secret_key' and 'starting_after' lack descriptions in the schema, and the description does not compensate. The description provides no additional meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: to list or create Stripe charges. It identifies the verb (list/create) and resource (charges). However, it does not differentiate between the two actions or clarify the scope, leaving some ambiguity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus its siblings (e.g., stripe_customers, stripe_invoices) or when to choose 'list' over 'create'. The description lacks context for decision-making.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for behavioral disclosure. It does not mention any behavioral traits such as mutation, idempotency, rate limits, authentication requirements (beyond the key), or error scenarios. The description is silent on what happens during creation or listing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely short (one sentence), which makes it concise but at the cost of essential details. It is front-loaded with the actions, but lacks structure or elaboration. It is under-specified rather than optimally concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (8 parameters, two operations) and lack of output schema, the description is very incomplete. It does not explain return values, pagination, error handling, or provide examples. An agent would struggle to use this tool correctly without additional information.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is low (38%), and the description adds no additional meaning to the parameters beyond what the schema already states. It does not explain the purpose of undocumented parameters like limit, email, name, phone, or description, nor how they affect list or create actions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly specifies the resource (Stripe customers) and the two actions (list or create). It is specific and distinguishes itself from sibling tools that handle other Stripe resources. However, it is minimal and does not elaborate on the scope of listing or the creation process.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use list vs create, or when to prefer this tool over alternatives. No context about prerequisites, typical use cases, or exclusion criteria. The agent has to infer usage from the parameter schema alone.

    With 6 parameters, no output schema, and no annotations, the description is incomplete. It does not cover return values, error scenarios, or any operational context needed for proper use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 67%; account_sid and auth_token lack descriptions. The tool description adds no parameter meaning beyond the schema, failing to compensate for the gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Send an SMS via Twilio' clearly indicates the action and resource. However, it does not distinguish from sibling tools like twilio_make_call or twilio_check_verify, missing an opportunity to differentiate.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, nor any prerequisites (e.g., needing a Twilio account). The description is silent on usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden for behavioral transparency. It only says 'get ... schedule', but does not disclose that authentication credentials (client_id, client_secret) may be required, or any rate limits, data freshness, or response format. This is insufficient for safe invocation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    While the description is short (one sentence), it is too brief to be useful. It lacks any structured breakdown of usage, parameters, or behavior. It is underspecified rather than appropriately concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 3 parameters, no output schema, and no annotations, the description is incomplete. It does not explain authentication needs, parameter meanings, or what the returned schedule looks like. The agent would likely need to guess or fail on first attempt.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage; the description adds no parameter information. broadcaster_id, client_id, and client_secret are not explained, leaving the agent without context on how to obtain or format these values.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (get) and resource (Twitch channel's streaming schedule). It is specific enough to distinguish from sibling tools like twitch_get_stream (current live stream) and twitch_channel_info (channel details), as schedule refers to future planned streams.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool vs alternatives, no prerequisites, no mention of authentication requirements (client_id/client_secret), and no exclusion criteria. The agent must infer usage context from the tool name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Without annotations, the description carries full burden, but it only states the basic function and does not disclose authentication requirements (client_id/secret), rate limits, pagination, or output format, which is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no fluff, but it is too terse and lacks necessary information; conciseness is okay but under-specified.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 3 undocumented parameters, no output schema, and no annotations, the description is severely incomplete, failing to explain authentication, parameter usage, or return data.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no explanation for any of the 3 parameters (first, client_id, client_secret), leaving the agent to infer their purpose.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'top games currently streaming on Twitch', which is specific and distinguishes it from sibling tools like twitch_search_games or twitch_get_stream.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must cover behavioral traits. It only says 'Get details' without mentioning response format, data freshness, rate limits, or any side effects. This is insufficient for informed use.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but omits essential details about parameters and return values. It is underspecified rather than efficiently structured.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and 0% parameter coverage, the description should detail what 'details' include and how the tool fits among siblings. It fails to provide enough context for an agent to use it effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The sole parameter event_id has 0% schema coverage and the description does not explain its purpose, format, or how to obtain it. The tool cannot be used correctly without this information.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves details for a specific USGS earthquake event, using the verb 'Get' and specifying the resource. It distinguishes from sibling tools like usgs_earthquakes_by_region and usgs_recent_earthquakes, which list multiple events.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when a specific event ID is known, but does not explicitly state when to choose this over siblings or provide exclusions. It lacks guidance on prerequisites or alternatives.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as being a read-only operation, data freshness, or pagination behavior. The description is insufficient to inform the agent about side effects or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence (9 words) which is concise, but it sacrifices necessary detail. It is appropriately sized for the tool's simplicity but lacks important elements like parameter explanations.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of three optional parameters and sibling tools, the description is incomplete. It does not define 'recent' (likely tied to period), explain the return format, or clarify how the tool differs from usgs_earthquake_detail or usgs_earthquakes_by_region. The absence of an output schema further burdens the description.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 3 parameters with only 33% description coverage (period). The tool description adds no information about the parameters (e.g., meaning of minmagnitude, limit unit, period options). The schema names and period enum provide some guidance, but the description fails to compensate for the low coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description specifies the tool retrieves 'recent earthquakes' from USGS, a clear verb-resource combination. It is distinguishable from sibling tools like usgs_earthquake_detail and usgs_earthquakes_by_region by name, though the description itself does not explicitly contrast them.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden of disclosing behavior. It lacks details on pagination, rate limits, authentication requirements, or output format. A simple 'List videos' is insufficient for full transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    While the description is short (5 words), it is under-specified. True conciseness provides sufficient information in few words; here, important context is missing, making it inadequate rather than concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of pagination (page_token) and limit (max_results) parameters, the description should explain these but does not. Without output schema, more behavioral detail is needed. The description covers only the minimal function.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% parameter description coverage, and the description adds no information about the four parameters (api_key, playlist_id, max_results, page_token). An agent receives no guidance on parameter usage or expected values.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states 'List videos in a YouTube playlist,' clearly indicating the action (list) and resource (videos in a playlist). This distinguishes it from sibling tools like youtube_list_playlists (lists playlists) and youtube_get_video (retrieves a single video).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, nor are prerequisites or conditions mentioned. The description only states the basic function without any contextual guidance.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits such as authentication requirements, rate limits, or error handling. The description only states the basic function, leaving the agent uninformed about side effects or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence. However, it could be expanded with key details without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations, no output schema, and zero parameter descriptions, the description is insufficient. It omits critical context such as authentication requirements, expected input format, and response structure, leaving the agent with only a vague understanding of the tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage—no parameter descriptions exist. The tool description does not explain the parameters beyond their names: 'abn' (required) and 'api_key' (optional). While 'abn' is self-explanatory, 'api_key' is not addressed, requiring the agent to infer its purpose.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool looks up an Australian Business Number (ABN) using the verb 'Look up', which is specific. However, it does not differentiate from the sibling 'abn_search' tool, which likely searches by name or other criteria, so purpose is clear but not fully distinguished.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like 'abn_search'. There is no context about prerequisites, limitations, or ideal use cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description only indicates a write operation ('report') but lacks details on side effects, authentication needs, rate limits, or what happens after reporting.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence is concise but overly brief for a tool with 4 parameters. Could include more detail without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 4 parameters, no output schema, and no annotations, the description is insufficient. It fails to explain required parameters like 'categories' format or optional parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage for parameters. Description does not explain 'categories', 'comment', or 'api_key' fields, leaving their meaning and format ambiguous.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the action ('report') and resource ('abusive IP address' to AbuseIPDB), distinguishing it from sibling tools like abuseipdb_check_ip and abuseipdb_blacklist.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, such as checking an IP first or prerequisites like API key. Missing context for ideal usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Without annotations, the description does not disclose behavioral traits like data freshness, time range of forecast, or pricing units. It only states what it does, not how or with what limitations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence but lacks necessary detail. It is not verbose, but it is under-specified for a tool with two parameters and no schema descriptions.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of schema descriptions and output schema, the description is inadequate. It does not explain the forecast's structure, time granularity, or any constraints, leaving significant gaps for the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the parameters. It does not explain 'site_id' (e.g., how to get it) or the optional 'api_key', leaving the agent without crucial context.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves an electricity price forecast for an Amber site, using a specific verb and resource. It is distinct from siblings like 'amber_current_price' and 'amber_sites'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool over alternatives, such as 'amber_current_price' for spot prices, or how to obtain a site_id. The description lacks context for prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description only implies approximation but does not clarify data source, rate update frequency, or error margins. Lacks disclosure of read-only nature or potential side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence is concise and front-loaded with the core purpose. No unnecessary words, though could benefit from slightly more detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, but the description fails to indicate return structure (e.g., converted amount, rate used). Missing details on edge cases or error handling. Inadequate for a tool with 3 required parameters and no annotations.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Input schema has no descriptions and 0% coverage. The description does not elaborate on parameter formats (e.g., ISO currency codes, amount rounding). Value added is minimal beyond what the parameter names imply.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Estimate currency conversion using a rough rate', clearly indicating the tool's function and the approximate nature of the conversion. It distinguishes from more precise conversion tools among siblings like 'exchangerate_convert'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like 'exchangerate_convert' or 'forex_convert'. The description does not mention suitability or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description is minimal. It does not disclose whether the tool requires authentication, rate limits, or what happens with invalid input. The description relies entirely on the tool's name to imply non-destructive behavior, lacking explicit behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no unnecessary words. However, it may be too brief for adequate understanding.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema, the description should explain return values but does not. It also lacks context on how to structure flight legs, whether passengers is optional, or that an API key is required. For a tool with 3 parameters, the description is incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 33% (legs parameter has a description). The tool description does not add any parameter details beyond what the schema provides, failing to compensate for the missing descriptions of 'passengers' and 'api_key'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Estimate carbon emissions for a flight.' It specifies a verb ('estimate') and a resource ('carbon emissions for a flight'), distinguishing it from sibling tools like carbon_electricity_emissions and carbon_vehicle_emissions by focusing on flights.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 33% (model and stop_sequences have descriptions). The description adds no parameter semantics beyond the schema. For low coverage, the description should compensate but fails to explain api_key, prompt, max_tokens, or temperature.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'generate' and resource 'text completions', and specifies the model family 'Cohere Command'. It distinguishes from sibling tools like cohere_chat and cohere_classify by focusing on completion rather than chat or classification, but does not explicitly contrast them.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool instead of siblings like cohere_chat or cohere_rerank. No context about prerequisites or appropriate scenarios is given.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits. It does not explain that the contrast ratio is typically related to WCAG accessibility standards, nor does it mention return format, limitations, or side effects. The tool is treated as a black box.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise with a single sentence, which is efficient for a simple operation. However, it sacrifices completeness for brevity. It is front-loaded with the action immediately.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema, the description should at least hint at the return value (e.g., a numeric ratio, passes/fails thresholds). It also lacks any context about color spaces or usage scenarios. The tool is simple but the description is insufficient for an agent to fully understand the tool's behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description adds no information beyond the parameter names (foreground, background). It does not explain that these are expected to be color values in formats like hex, RGB, etc., nor does it provide format requirements or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Check') and the resource ('contrast ratio between two colors'). It distinguishes this tool from siblings like color_convert, color_info, color_mix, and color_palette by using the specific term 'contrast ratio', which is a distinct operation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided about when to use this tool versus alternatives. There are no hints about prerequisites, such as needing to know color formats, or when not to use it. The description is a single sentence with no usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behavioral details. It only states 'convert', implying a pure computation with no side effects, but does not confirm read-only nature or explain any special behavior like rounding or error handling.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is one short sentence with no redundancy. It is efficiently concise, though it could benefit from more detail without harming conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple converter with 3 parameters and no output schema, the description falls short. It lacks examples, supported units, and return format, making it incomplete for confident use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate. It adds no meaning to the parameters (value, from, to) beyond their names. The agent is left guessing valid unit strings and input format.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Convert between data storage units' clearly states the action (convert) and resource (data storage units), distinguishing it from other convert tools for different unit types. However, it does not list the specific units supported, which slightly reduces clarity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like convert_area or convert_length. There is no mention of context or preferred unit formats, leaving the agent to infer usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must fully disclose behavior. It only states the conversion function, omitting details like supported units, precision, range, or output format, which are critical for a conversion tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence, but it sacrifices completeness for brevity. While not overly verbose, it lacks structure and fails to convey essential information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple conversion tool, the description should at minimum mention supported units or provide an example. Without this, an agent lacks enough context to correctly invoke the tool, making it incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate. It fails to explain that 'from' and 'to' are unit strings (e.g., 'kg', 'lb'), list supported units, or provide any parameter context beyond the schema's bare names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the tool converts between weight/mass units, clearly distinguishing it from sibling converters for area, length, temperature, etc. The verb 'Convert' and resource 'weight/mass units' are specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., convert_length for length conversions). There is no mention of prerequisites, exclusions, or context-specific usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full responsibility for behavioral transparency. It only states 'Get a country by name', which implies a read operation, but does not disclose rate limits, authentication needs, or any other behavioral traits beyond the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it could include critical details without becoming verbose. It achieves conciseness at the cost of completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of many country-related sibling tools and the absence of an output schema, the description is insufficient. It fails to explain when to prefer this tool over alternatives or how the tool behaves (e.g., case sensitivity, exact vs partial match).

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has two parameters (name, fullText) with 0% description coverage. The description adds no meaning beyond the schema, leaving 'fullText' undefined. For a boolean parameter, the lack of explanation (e.g., 'set to true for exact match') is a significant gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'a country by name', and the source 'REST Countries'. It is specific and distinguishes itself from sibling tools by explicitly mentioning 'by name'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus the many country-related siblings (e.g., country_by_code, country_by_region). The name implies usage but no explicit when-to-use or when-not-to-use information.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only states 'Create a new item', implying mutation but offering no details on side effects, authentication requirements, rate limits, or what the created item entails. This is insufficient for a mutable operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that front-loads the verb and resource, avoiding unnecessary words. While concise, it is appropriately sized for a simple creation tool, though it could benefit from a brief structure listing key parameters or usage hints.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema and no annotations, the description should explain what the tool returns or any important context like required parameters. It does not mention that board_id and item_name are required, nor does it describe the return value. This leaves significant gaps for an agent to understand the tool's full behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description does not elaborate on any parameter beyond what is in the schema. Though the schema covers 4 of 5 parameters with basic descriptions, the tool's description adds no extra meaning. Notably, the api_key parameter lacks a schema description and is not addressed in the tool description, leaving ambiguity.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('Create') and resource ('a new item in a Monday.com board'), distinguishing it from sibling tools like update_monday_item or list_monday_items. However, it lacks additional scope details such as specifying that the item is created within a board, which is implied but not explicitly elaborated.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. With siblings like update_monday_item and list_monday_items, the description should offer context on when creation is appropriate, but it fails to do so.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must fully disclose behavior. It only states the core action, omitting details on side effects (if any), error handling, timezone handling, or return type. For a date arithmetic tool, this is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Description is a single, concise sentence. However, for a tool with 6 parameters, a bit more structure (e.g., note on timezone) would improve clarity without harming conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, no annotations, and 6 parameters without descriptions. The description fails to explain return value, valid date formats, or constraints, making it incomplete for an agent to use correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the tool description does not describe any parameter (e.g., date format, units, constraints). The agent receives no additional meaning beyond the schema field types and required field.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Add a duration to a date' clearly states the tool's action (add) and resource (date), distinguishing it from sibling tools like datetime_date_diff or datetime_format_date.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives like datetime_business_days or datetime_convert_timezone. The description does not mention prerequisites, use cases, or when not to use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. Description only states 'search' without disclosing pagination, authentication, rate limits, or result format. Behavioral traits are not conveyed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise (5 words) but lacks necessary detail. Conciseness is good but structure is too sparse for a tool with undocumented schema and no annotations.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no annotations, no output schema, and 0% schema coverage, the description is incomplete. Does not specify what the search returns or how to interpret results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage. Description does not explain any parameter (q, api_key) despite being the only source for parameter meaning.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'search' and resource 'artists on Discogs', distinguishing it from sibling 'discogs_search_releases' which searches releases.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like discogs_get_artist or discogs_search_releases. No mention of context or prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description fails to mention behavioral aspects such as rate limits, search result pagination, or how releases are matched. The description is overly simplistic.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, minimal sentence that is concise but lacks necessary information. It is not overly verbose, but under-specification reduces its value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 7 parameters, no output schema, and no annotations, the description is incomplete. An AI agent would lack crucial context about parameters like 'api_key' (required? usage?) and search behavior. More detail is needed for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Despite 7 parameters with 0% schema description coverage, the tool description provides no additional meaning about the parameters such as 'q', 'artist', 'type', 'format', 'genre', 'year', or 'api_key'. No parameter usage details or constraints are mentioned.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Search') and resource ('music releases on Discogs'), effectively differentiating it from sibling tools like discogs_search_artists or discogs_get_release.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like discogs_get_release for precise release data or discogs_search_masters for master releases. No exclusions or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description fails to disclose behavioral traits. It does not state that this is a read-only operation, mention authentication requirements, or describe the nature of the response (e.g., a hierarchical tree). The description is minimal and adds no behavioral context beyond the tool's name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at 9 words, but it sacrifices necessary detail. While it is front-loaded and to the point, it omits critical information about parameters and usage, making it minimally adequate.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters, no output schema, and no annotations, the description is incomplete. It does not explain what the category tree contains, how it is structured, or how to use the parameters effectively. The description is too sparse to guide correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 4 parameters with only 25% description coverage (only category_tree_id has a description). The tool description adds no additional meaning for parameters like client_id, client_secret, and marketplace. Since schema coverage is low, the description should compensate but does not, leaving the agent without guidance on how to properly populate these fields.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves the eBay category tree for a given marketplace. It uses a specific verb-resource pair ('Get' + 'category tree') and is distinct from sibling tools like ebay_get_item, ebay_get_item_by_legacy_id, and ebay_search, which focus on items or searches.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description lacks any guidance on when to use this tool versus alternatives, such as ebay_search. It does not mention prerequisites like needing a marketplace identifier or how to determine the category_tree_id. The agent is left to infer usage from the schema.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It fails to mention that an API key is required (despite being in the schema), whether the tool is read-only, rate limits, or error handling. The description is too vague to inform an agent of the tool's behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but omits essential details. It is underspecified for a 4-parameter tool with no output schema, making it not appropriately sized for the tool's complexity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of annotations, output schema, and only 50% schema description coverage, the description is severely incomplete. It does not explain the response format, authentication, parameter constraints (e.g., maxResults), or how to specify a region correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (regionCode and back have descriptions). The tool description adds no additional meaning beyond the schema. While the schema itself includes examples (e.g., 'AU-VIC'), the description does not clarify maxResults or api_key, leaving ambiguity.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'recent bird observations from eBird', but does not differentiate from sibling tools like ebird_notable_observations or ebird_species_info, nor does it specify what 'recent' means or the required region parameter.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., ebird_notable_observations). No context on prerequisites, region selection, or intended use cases is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It does not disclose what the response contains, error behavior on invalid UID, or the roles of the 'folder', 'email', and 'password' parameters (likely authentication). Behavior is opaque.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence with no redundant words. It is front-loaded with the verb and resource. However, brevity comes at the cost of omitting essential parameter context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema, no annotations, and minimal description, the tool's behavior and parameter semantics are severely under-specified. Four parameters exist but only one is addressed; the agent lacks sufficient context to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description only mentions the 'uid' parameter. The meaning of 'folder', 'email', and 'password' is not explained, leaving the agent uninformed about their purposes (likely authentication or mailbox selection).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and resource ('specific email') and identifies the key selector ('by UID'). It is unambiguous, but it does not differentiate from sibling tools like email_search or email_read_inbox, which also retrieve emails.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, such as email_search. The description does not explain prerequisites or context for usage, leaving the agent to infer.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden but fails to disclose behavioral traits, such as whether the tool is idempotent, requires authentication (implied by parameters), or what happens if the email is already marked as read.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise (one sentence), but it is too brief, omitting essential information, so it does not earn its place despite being short.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool requiring authentication and having an output schema, the description is incomplete; it lacks details on authentication, parameter roles, and return behavior, making it insufficient for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%, and the description adds no meaning to the four parameters (uid, folder, email, password). It does not explain that uid is the email identifier, folder is optional, or that email/password might be used for authentication.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Mark an email as read,' which is a specific verb and resource, and it distinguishes from sibling tools like email_delete and email_search.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as suggesting to first list emails with email_read_inbox, or mentioning prerequisites like authentication.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral disclosure. It fails to mention that email and password parameters are for authentication, any rate limits, delivery guarantees, or error scenarios. The description is too minimal to inform an agent about side effects or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    While very concise (one sentence), the description is under-specified for a tool with 7 parameters and no annotations. It sacrifices necessary detail in favor of brevity, leaving critical information absent.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (7 parameters, no annotations, no output schema), the description is grossly incomplete. It does not explain authentication, return value, or how to handle failures. Among sibling email tools, it is the only send tool, but that context is not leveraged.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the description does not explain any parameter's meaning beyond their names. It adds no value over the schema—missing details like the format of 'to' (single or comma-separated?), or that 'email' and 'password' are authentication credentials.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Send an email via Gmail/IMAP' clearly states the action (send email) and the service (Gmail/IMAP), distinguishing it from sibling tools like email_delete, email_get, email_read_inbox, and email_search which perform different operations.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, typical use cases, or situations where another email tool (e.g., email_read_inbox) would be more appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully disclose behavior. It only says 'Search esports players' but does not mention read-only nature, return type, authentication, or any side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it is too brief to be useful. It fits the tool name but lacks necessary details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple search tool, the description is incomplete. No output schema exists and parameter semantics are missing. It does not explain what data is returned or how to use the parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the description adds no meaning beyond parameter names. It does not explain what 'search' expects (e.g., player name) or the purpose of 'api_key'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Search) and the resource (esports players) on a specific platform (PandaScore). It distinguishes itself from sibling tools like esports_teams, esports_matches, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like esports_teams or esports_matches. No context about prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral disclosure. It only states 'Get details', which implies a read operation, but does not specify if it requires authentication, what happens if the venue_id is invalid, or the type of data returned. This is insufficient for an agent to understand the tool's behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no unnecessary words. It is front-loaded with the verb 'Get' and the resource. However, it sacrifices completeness for brevity, leaving important details unstated. It earns a 4 for conciseness but is on the edge of being too terse.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no parameter descriptions, the description is incomplete. It does not explain what 'details' entails (e.g., address, capacity, etc.), nor does it cover error handling or prerequisites. A more comprehensive description would improve the agent's ability to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must add meaning. The description does not explain the purpose of venue_id or api_key beyond their names. For example, it does not clarify that venue_id is the Eventbrite venue ID or that api_key is optional. The agent relies solely on parameter names, which may be ambiguous.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets details for an Eventbrite venue, using the verb 'Get' and the resource 'venue'. It is not a tautology as it adds the word 'details'. However, it does not differentiate from sibling tools like eventbrite_get_event or eventbrite_get_attendees, which are similar in structure but for different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description does not mention scenarios where this tool is appropriate or not, nor does it reference siblings such as eventbrite_search_events or eventbrite_get_event. The agent is given no context for selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and description lacks behavioral context such as side effects, data freshness, or limitations. It only states the basic function; does not disclose that it is a read-only operation or any other traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Description is a single short sentence, which is concise but overly minimal. It lacks structure and additional details that could aid understanding.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple data retrieval tool with one parameter and no output schema, the description is incomplete. It does not specify the return format, possible values, or any dependency on other tools, leaving the agent to infer missing information.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage for the required 'session_key' parameter. Description adds no explanation about what a session_key is or how to obtain it, which is crucial for correct invocation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the verb 'Get', the resource 'Formula 1 weather data', and the source 'OpenF1'. Among many F1 sibling tools, this distinguishes itself as the weather-specific tool.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use or when not to use this tool. No mention of alternatives or prerequisites like obtaining a session_key from another F1 tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the burden. It indicates a read-only list operation without side effects, but does not disclose authentication requirements, rate limits, or return format. Adequate but minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence. However, it lacks details that could be included without verbosity, such as what the list contains. It is not overly long but could be more informative.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Without an output schema, the description should explain the return value. It fails to do so, leaving the agent unaware of whether the result includes currency codes, names, or symbols. Missing context on api_key necessity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The only parameter 'api_key' is not mentioned in the description. With 0% schema coverage, the description adds no meaning beyond the schema, leaving the agent uninformed about whether the key is required or optional.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists all currencies from Open Exchange Rates. The verb 'List' and resource 'currencies' are specific, but it does not differentiate from sibling tools like 'exchangerate_codes' which may serve a similar purpose.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as forex_latest or forex_convert. Lacks any context about prerequisites, typical use cases, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description bears full responsibility for behavioral disclosure. It only states 'Get a forex exchange rate' without mentioning whether it returns real-time data, historical data, or any rate limits. This is insufficient for an agent to understand side effects or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at 6 words and front-loaded with the action. However, it could be expanded slightly to cover key details without losing efficiency. Given its brevity, it is well-structured but lacks necessary information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 3 parameters and no output schema, the description is too terse. It does not explain how to form a request, what the response contains, or any required formatting. The agent is left without enough context to use the tool effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description fails to explain any parameters. Although parameter names like from_currency and to_currency are somewhat self-explanatory, no format or expected values (e.g., ISO codes) are provided. The api_key is not described either, leaving the agent guessing.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'forex exchange rate' from 'Alpha Vantage'. However, it does not distinguish itself from sibling tools like forex_convert, forex_historical, or forex_latest, which also retrieve forex rates. Thus, it lacks sibling differentiation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite the tool's simplicity, the description omits parameter explanations and response structure. With no output schema, the agent lacks essential context to correctly invoke and interpret results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain either parameter. 'channel_access_token' and 'user_id' are not defined, leaving the agent to infer from names alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves a LINE user's display name, profile picture, and status message. It is specific and distinguishes from sibling tools like line_get_group_summary, though it does not explicitly exclude group contexts.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., line_get_group_summary). No mention of prerequisites like needing a valid channel access token or user ID format.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description does not disclose behavioral traits beyond the basic action. With no annotations, it should explain authentication requirements, pagination behavior, and potential rate limits, but it fails to do so.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with one sentence, containing no wasted words. It is appropriately sized but could be structured better with additional context without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and the tool's complexity (pagination, authentication), the description is incomplete. It omits return format, pagination details, and error cases, which are essential for a list tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 67% description coverage, but the tool's description adds no extra meaning. It does not explain that access_token is an OAuth token or clarify the purpose of cursor for pagination, leaving parameter understanding to the schema alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (list) and resource (videos) for the authenticated user, providing a specific verb+resource combination. However, it lacks differentiation from sibling tools like list_asana_tasks or list_pins, which are also list operations.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites (e.g., authentication) or when not to use it, leaving the agent without context for tool selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only states that the tool gets results, implying a read operation, but lacks details on authentication, data freshness, rate limits, or error handling. This is insufficient for an agent to anticipate behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that quickly conveys the core function. It avoids unnecessary words. However, it is arguably too terse, sacrificing informative detail for brevity. A slightly longer description could maintain conciseness while adding valuable context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of an output schema, the description should explain what the results contain (e.g., winning numbers, prize breakdown, draw date). It fails to do so. The tool's functionality is only partially described, leaving significant gaps about the return value and result structure.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 50% description coverage (game parameter described, draw_number not described). The tool description does not add any parameter information beyond the schema. It fails to explain what happens when parameters are omitted, valid values for draw_number, or how results are filtered. The description does not compensate for the schema gaps.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'Australian lottery results' from 'The Lott'. It conveys the tool's purpose effectively, though it does not explicitly differentiate from the sibling tool 'lott_jackpots', which likely deals with jackpot amounts. However, the term 'results' versus 'jackpots' provides implicit distinction.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. No mention of prerequisites, use cases, or when not to use it. The only information is the basic purpose, leaving the agent without decision-making context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the basic operation and does not mention authentication requirements, error handling, or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence of 8 words that is perfectly concise and front-loaded with the essential action, with no wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple retrieval tool with two parameters, the description is too minimal. It lacks information about return values, error conditions, and prerequisite authentication, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage, and the description does not add meaning to the parameters beyond the schema. The api_key parameter is not explained, and order_id is only implied by 'by ID'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'Lemon Squeezy order', and specifies the retrieval is 'by ID', distinguishing it from sibling tools like ls_list_orders that list orders.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as ls_list_orders. The description does not mention context or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must convey behavioral traits. It merely states 'List orders' without disclosing whether it is read-only, requires authentication (implied by api_key but not stated), supports pagination, or has rate limits. The agent gains minimal behavioral insight beyond the tool name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at one sentence, with no wasted words. However, it lacks structure (e.g., bullet points or sections) that could help parse information quickly. For a tool with multiple parameters, slightly more structure would improve clarity without sacrificing brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters, no output schema, and no annotations, the description is severely incomplete. It does not address pagination, filtering by user_email, authentication via api_key, or the response format. The agent has insufficient information to use the tool correctly without external knowledge.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, leaving description to clarify parameters, but it does not mention any. Parameter names like api_key, store_id, user_email, page, per_page are self-explanatory to some extent, but the description adds no value in explaining their purpose, defaults, or constraints. This is a critical gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'list' and the resource 'orders' within the context of 'a Lemon Squeezy store'. This is distinct from sibling tools like ls_list_customers or ls_list_products, and it differentiates from ls_get_order (which retrieves a single order). The purpose is immediately understandable.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, such as ls_get_order for a specific order or other list tools. There is no mention of prerequisites, filtering options, or pagination usage. The description lacks any contextual hints for effective selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as pagination, authentication requirements, rate limits, or what scope of store data is returned. The description is too vague to inform an agent about side effects or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (one sentence, 6 words), but it sacrifices essential information. It is minimally adequate but lacks structure and completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given that there are 4 parameters, no output schema, and no annotations, the description is insufficient. It does not mention how to authenticate (api_key) or filter by store, nor does it indicate required or optional parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 4 parameters (api_key, store_id, page, per_page) with 0% schema description coverage. The description does not explain any parameter meaning, format, or required values, forcing an agent to guess.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List', the resource 'products', and the context 'in a Lemon Squeezy store'. It distinguishes itself from sibling tools like 'ls_list_customers' and 'ls_list_orders' by specifying 'products'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, best practices, or exclusions.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 6 parameters and no output schema, the description is incomplete. It does not explain pagination, optional filters, or the expected response format, leaving significant gaps for an agent to use correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Only 17% of parameters have schema descriptions (status). The tool description adds no explanation for api_key, store_id, order_id, page, or per_page, leaving the agent without semantic understanding. This does not compensate for the low schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states it lists subscriptions for a Lemon Squeezy store, with a specific verb and resource. It distinguishes from sibling tools like ls_list_customers and ls_list_orders, which focus on different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full responsibility. It discloses the core action but omits critical behavioral details such as token limits, streaming support, error handling, cost implications, or authentication requirements (api_key is a parameter but not mentioned). The description provides minimal behavioral insight.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single succinct sentence, front-loading the key verb and resource. It is efficient with no wasted words, though it could be slightly more structured to improve scannability.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 8 parameters and no output schema, the description is overly brief. It does not mention required parameters (prompt or messages), return format, or potential errors, leaving agents without sufficient context for correct invocation.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no parameter information beyond what the input schema already provides. Schema coverage is 50% (4 of 8 parameters described), and the description does not compensate for the undocumented parameters, such as system_prompt, max_tokens, temperature, and top_p.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool performs a chat completion using Mistral AI models, listing example model IDs. This distinguishes it from non-chat tools, but does not explicitly differentiate from other chat completion tools among siblings, though the mention of 'Mistral' implies the provider.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is given on when to use this tool instead of alternatives (e.g., OpenAI, Groq, etc.), nor any prerequisites or explicit exclusions. The description simply states what it does without context for selection.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'cancel' and the resource 'outstanding emergency Pushover notification'. It differentiates from sibling tools like pushover_send_notification and pushover_get_receipt by specifying the action on emergency notifications.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, such as waiting for expiration or using pushover_get_receipt to check status. The description only states what it does, not when it should be used.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No behavioral traits disclosed beyond the basic read operation. No annotations exist, so description should cover aspects like pagination or data format, which it does not.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise single sentence, no redundancy. However, it may be too terse for full clarity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and a sibling list with many radio tools, the description lacks details on return format, pagination, or typical usage, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage; the description only implies that 'country' filters stations, but does not clarify format (e.g., country code or name) and ignores 'limit' entirely.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the action 'Get' and resource 'radio stations' with a specific filter 'by country', which distinguishes it from siblings like 'radio_by_tag' and 'radio_search'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., 'radio_search' for broader queries). No when-not-to-use or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits beyond the basic purpose. For a generation tool, information about randomness, reproducibility, or output format would be helpful but is missing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it omits essential details like parameter usage. While not verbose, it lacks sufficient structure to fully inform the agent.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool, the description is barely adequate. It does not explain return values, parameter relationships (e.g., exclusive use of paragraphs vs words vs sentences), or any edge cases. The missing output schema and lack of param details leave gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema defines three parameters (paragraphs, words, sentences) with no descriptions. The tool description adds no information about these parameters, leaving the agent to guess their behavior and interactions. Since schema coverage is 0%, the description should compensate but fails to do so.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Generate lorem ipsum placeholder text' clearly states the action (generate) and the resource (lorem ipsum placeholder text). It is specific and distinguishes this tool from all siblings, none of which focus on lorem ipsum generation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description does not specify context, prerequisites, or when not to use it. Given the simple nature, some implicit usage is clear, but explicit directions are absent.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description bears full responsibility for disclosing behaviors. It only states a list operation without mentioning response format, pagination, rate limits, or auth requirements. This is insufficient for transparent behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (one sentence) but lacks any structure or sections. It is not verbose, but the brevity sacrifices clarity expected for a tool with no annotations.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given zero annotations, no output schema, and 0% parameter coverage, the description is incomplete. It fails to address basic aspects like api_key usage, response details, or error handling, even for a simple list tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate. However, it does not mention the api_key parameter at all, leaving the agent to rely solely on the schema's bare type and name.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List all game genres on RAWG' clearly states the action (list) and resource (game genres). It distinguishes itself from sibling tools like rawg_get_game, rawg_search_games, and rawg_list_platforms by specifying a unique data type.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, typical use cases, or exclusions, leaving the agent to infer usage independently.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description lacks details about authentication (api_key is optional but not explained), pagination, rate limits, or output structure. The description adds minimal behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but under-specified for a tool with a parameter. It could be expanded without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a list tool with one optional parameter and no output schema, the description is too minimal. It does not clarify what platforms are returned, if the api_key is required, or if pagination exists.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not mention or explain the 'api_key' parameter. The description adds no value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ("List") and the resource ("all gaming platforms on RAWG"), distinguishing it from siblings like igdb_list_platforms which lists platforms from IGDB.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, such as igdb_list_platforms or keychain_list_platforms. No usage context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden to disclose behavioral traits. It says nothing about side effects, required authentication, rate limits, or whether the post creation is immediate. The mere statement 'Create a Reddit post' is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but severely underspecified. While it earns its place by stating the core purpose, it lacks necessary details to be considered appropriately sized for a tool with 8 parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (8 parameters, 4 required) and no output schema, the description is incomplete. It fails to explain return values, authentication requirements (access_token), or how choose post type (kind), leaving significant gaps for the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 8 parameters with only 13% description coverage (only the 'kind' parameter has a description). The tool's description adds no information about parameters such as access_token, subreddit, title, text, url, nsfw, or spoiler, leaving the agent to rely on parameter names alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Create a Reddit post.' clearly states the verb (create) and the resource (Reddit post), and it naturally distinguishes from sibling tools like reddit_comment, reddit_read, etc., which perform different actions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as reddit_comment or reddit_search. The description does not mention when not to use it or any prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden. It does not disclose behavioral traits such as read-only nature, rate limits, pagination, or how the access_token is used. The minimal 'Search Reddit posts' adds negligible value over the name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (one short sentence), but it is too sparse. While front-loaded and not verbose, it sacrifices necessary detail. A balanced description could include more guidance without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a search tool with 5 parameters (2 required) and no output schema, the description is incomplete. It does not explain the return format, sorting behavior, or the role of the access_token, leaving the agent with insufficient context to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description provides no explanation of parameters. The agent receives only parameter names and types, with no indication of what 'q', 'subreddit', 'sort', or 'limit' mean or how to use them.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Search') and the resource ('Reddit posts'), distinguishing it from sibling tools like reddit_comment or reddit_post which focus on other actions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, nor does it mention when not to use it. The description lacks any conditional or contextual advice.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral disclosure. It states 'List public models' implying a safe read operation, but fails to mention pagination (cursor parameter), rate limits, response structure, or any side effects. The description adds minimal value beyond the inferred read-only nature.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, but it omits important details that would justify its brevity. It is not verbose, but it is under-specified, sacrificing completeness for conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple listing tool with two parameters and no output schema, the description is too minimal. It fails to explain pagination via cursor, the authentication requirement, or the nature of the returned data. The tool's complexity is low, so a complete description could easily cover these points.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate. It does not mention either parameter: api_token (required for authentication) or cursor (for pagination). The agent must rely solely on the schema names, which lack any descriptive context.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List', the resource 'public models', and the scope 'on Replicate'. It distinguishes this tool from sibling Replicate tools like replicate_get_model (single model) and replicate_list_predictions (list predictions), as well as from similar list_models tools from other providers.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention use cases, prerequisites (e.g., authentication implied by required api_token), or scenarios where listing models is appropriate, such as before creating a prediction.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full weight for behavioral disclosure. It only states 'List domains' without confirming read-only nature, authentication requirements, rate limits, or output format—leaving important behavioral traits unspecified.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 31 characters, which is concise but borderline terse. It could include a bit more context (e.g., output scope) without becoming verbose, so it's adequate but not exemplary.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of an output schema and only one optional parameter, the description should clarify what 'domains' refers to and whether the list is complete or filtered. It fails to provide this context, leaving the tool's behavior under-specified.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has one parameter (api_key) with no description (0% coverage). The description does not mention or explain the api_key parameter, adding no meaning beyond the schema itself.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('List') and resource ('domains configured in Resend'), making the tool's purpose immediately understandable. It is distinct from sibling tools like resend_get_email and resend_send_email, which target different actions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool instead of alternatives, nor any context on prerequisites or scenarios where listing domains would be appropriate or inappropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. The description does not disclose read-only behavior, rate limits, authentication requirements, or response structure. Minimal disclosure beyond the action itself.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence is efficient, but sacrifices necessary detail. Could be structured with a brief line about parameters or behavior without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 4 parameters, no output schema, and no annotations, the description is insufficient for an agent to reliably invoke the tool. Missing details about region conventions, API key handling, and response format.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. The description mentions only PUUID as identifier, but does not explain region (e.g., required format like 'na1'), count (max number?), or api_key. Parameters lack context for correct usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Get), resource (match history), and identifier (PUUID). However, it does not differentiate from sibling tools like riot_get_match or riot_ranked, leaving ambiguity about what 'match history' entails versus single-match retrieval.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., riot_get_match for a single match). No prerequisites mentioned (e.g., obtaining PUUID from riot_summoner). No context about required region format or API key usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It only states 'get ranked stats' without explaining the return format, authentication (api_key field present but not mentioned), rate limits, or data freshness. This is insufficient for a tool with no annotation support.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise (one sentence, 8 words) but is under-specified. It effectively communicates the tool's core purpose without unnecessary words, but it lacks critical details that would justify a higher score for completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 3 parameters, no output schema, and no annotations, the description is minimal. It does not explain what ranked stats include, how to interpret the region parameter, or the purpose of api_key. The absence of output schema increases the need for description completeness, which is unmet.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning the description adds no meaning to any of the 3 parameters (summonerId, region, api_key). Even the required parameter summonerId is unexplained. The description fails entirely to clarify parameter roles or formats.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get ranked stats for a League of Legends summoner' clearly states the action (get) and the resource (ranked stats) with the context (League of Legends summoner). It distinguishes from sibling tools like riot_get_match or riot_summoner, which serve different purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, prerequisites (e.g., needing a summoner ID from riot_summoner), or context like what region values are accepted. The description lacks any usage direction.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, description must disclose behavioral traits. It only says 'Get rosters' without detailing what rosters include, pagination, rate limits, or data freshness. Lacks essential behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise (7 words) but underspecified. While not verbose, it sacrifices necessary detail. Earns its place but incomplete.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema and minimal description. Does not explain what the rosters contain or how to interpret results. Incomplete for effective tool use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and description does not explain league_id parameter. Does not add meaning beyond the schema. A single required parameter should be elaborated.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'Get' and resource 'rosters for a Sleeper fantasy league'. It distinguishes from sibling tools like sleeper_league, sleeper_league_matchups, sleeper_players, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. Does not mention prerequisites like needing league_id from sleeper_league or any context for appropriate usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must bear the burden of behavioral disclosure. The two-word description gives no insight into what 'trending' means, whether the tool is read-only, or any side effects. Important behavioral traits like caching, rate limits, or data freshness are omitted.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at five words. It delivers the core purpose without any fluff. However, it sacrifices necessary detail for brevity. It could be restructured to include more information while remaining efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 optional parameters, no output schema, and no annotations, the description is woefully incomplete. It fails to define 'trending', explain parameter usage, or describe the output format. This forces the agent to guess or potentially misuse the tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 25% (only the 'type' parameter has a description). The overall description does not explain the parameters: 'sport' (possible values?), 'lookback_hours' (range?), 'limit' (max?). This leaves the agent guessing about valid inputs, especially since none are required.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get trending players on Sleeper.' clearly states the action (get) and resource (trending players). It is specific enough to distinguish from sibling tools like sleeper_players (which likely gets all players) or league-specific tools. However, it does not explicitly differentiate from other potential trending tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. It does not mention prerequisites, context, or situations where this tool is preferred. The agent is left without any decision support regarding tool selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral disclosure. It fails to explain authentication requirements (bearer token), rate limits, or what happens with large track lists. The minimal description does not sufficiently inform the agent about the tool's safety or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with no unnecessary words. It is appropriately concise, though it sacrifices completeness for brevity. It earns a high score for conciseness but is not perfectly structured with front-loaded key information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and low schema coverage, the description should provide hints about the return structure or usage context. It does not mention that the output will include playlist metadata and track objects, or that pagination may be needed. The description is too minimal for a tool with three parameters and no schema documentation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must add meaning to parameters. It does not clarify that 'bearer_token' is a Spotify API token, that 'playlist_id' is the Spotify ID, or that 'market' filters by region. The description adds no semantic value beyond the parameter names in the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves metadata and tracks for a Spotify playlist, providing a specific verb and resource. However, it does not differentiate from sibling tools like spotify_get_album or spotify_get_track, missing an opportunity to clarify its unique scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is given on when to use this tool versus alternatives such as spotify_search or spotify_get_recommendations. The description lacks context for choosing this tool over others, leaving the agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for behavioral disclosure. It fails to mention that the tool returns a list of track objects, requires authentication (though bearer_token is in schema), or any rate limits or side effects. The description only hints at input types nothing about output behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at one sentence. It efficiently conveys the core function. However, the conciseness comes at the cost of omitting critical usage and parameter details, so it is not optimally balanced.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (10 parameters, no output schema), the description is severely incomplete. It provides no explanation of the output format, the constraint of max 5 seeds total, the meaning of audio feature target parameters, or the market filter. An agent would require external knowledge to use this tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 30% (only seed_tracks has a description). The description adds no extra parameter semantics beyond mentioning seed tracks, artists, or genres. It does not explain the purpose of limit, market, audio feature parameters (energy, valence, danceability), or bearer_token. This leaves most parameters as opaque properties.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves Spotify track recommendations based on seed tracks, artists, or genres. It uses a specific verb ('Get') and resource ('track recommendations'), and implicitly distinguishes from sibling tools like spotify_get_track, spotify_search, etc., which serve different purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., spotify_search for general discovery, spotify_get_track for specific tracks). It does not mention prerequisites like needing seed IDs from other tools, nor what types of recommendations to expect.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must convey behavioral traits. It only says 'Get metadata,' implying a read operation, but fails to mention authentication requirements (bearer token is in schema but not explained), rate limits, or the nature of the return data. This is minimal transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that front-loads the verb and resource. It is efficient with no unnecessary words. However, it could be slightly more informative without sacrificing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of many sibling Spotify tools (e.g., spotify_get_album, spotify_get_audio_features) and no output schema, the description is insufficient. It does not clarify what 'metadata' includes or when to prefer this tool over similar ones, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain any parameters. It only implies that track_id is used (by saying 'by ID'), but provides no details on bearer_token, market, or what valid values are. The description adds no semantic value beyond the parameter names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Get metadata for a Spotify track by ID,' which clearly identifies the verb (Get), resource (metadata for a Spotify track), and method (by ID). This differentiates from siblings like spotify_get_album or spotify_get_artist, though it could be more explicit about what 'metadata' includes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as spotify_get_audio_features or spotify_search. The description does not mention use cases, prerequisites, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits such as read-only nature, error handling, rate limits, or authentication requirements. The agent is left uninformed about side effects or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no unnecessary words, but it is too brief and lacks structured breakdown of inputs or outputs.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description should explain what is returned (e.g., list of meetings with details). It also omits context about the domain, required parameters, and authentication. The tool is simple but still incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds minimal value beyond the schema; it only references 'date'. The api_key parameter lacks any description in both schema and description, and jurisdiction's schema description is already sufficient. With 67% schema coverage, the description should compensate but does not.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'TAB race meetings', and specifies the key filter 'date'. However, it does not mention other important inputs like jurisdiction or api_key, and lacks differentiation from sibling tools like tab_race.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus siblings (tab_race, tab_sports_markets) or any prerequisites. The description gives no context for appropriate usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so the description must disclose behavioral traits. It only states 'Get popular TV shows', failing to mention pagination (despite a `page` parameter), rate limits, or the meaning of 'popular'. The return format is also unspecified.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence with no waste, but given the tool's complexity (2 parameters, many siblings), it is too minimal to be effective. It lacks necessary front-loaded context about pagination or alternatives.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Without an output schema, the description should explain return values or pagination. It does not. Combined with low parameter documentation and no usage guidelines, the description is incomplete for correct tool use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not mention either parameter (`page`, `api_key`). The agent receives no guidance on purpose or constraints of these inputs, leaving them entirely undocumented.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get'), resource ('popular TV shows'), and source ('from TMDB'). Among sibling tools, it distinctly contrasts with `tmdb_search_tv`, `tmdb_tv`, and `tmdb_trending`, making its purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    There is no guidance on when to use this tool versus alternatives. With multiple TMDB TV-related siblings, the lack of usage context (e.g., 'for a list of trending shows use tmdb_trending') makes it harder for the agent to choose correctly.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description does not disclose any behavioral traits such as rate limits, authentication requirements, or error handling (e.g., what happens if ID is invalid).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    It is concise (one short sentence) but does not earn its place as it omits critical details. It could be expanded without losing brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema and no annotations. Description is too sparse given the complexity of the Trove API. Lacks any information about response format or additional constraints.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% and description adds no meaning beyond parameter names. The 'id' and 'api_key' parameters are undocumented, leaving the agent without type or format hints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (get) and resource (Trove newspaper article) with the identifier (by ID). It distinguishes from sibling tools like trove_search and trove_get_work.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this vs alternatives like trove_search or trove_get_work. No prerequisites or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully disclose behavioral traits. It only says 'Search', but does not mention required authentication (api_key parameter), rate limits, response format, or mutation side effects. This is insufficient for safe and correct invocation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very short (7 words) and front-loaded. It is concise, but the brevity sacrifices necessary detail. It earns a 4 for lack of fluff, but not a 5 because it omits crucial information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters (including an undocumented api_key), no output schema, and no annotations, the description is far from complete. It does not provide enough context for an AI agent to understand inputs, outputs, or usage constraints.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (zone and n have descriptions, query and api_key do not). The description adds no additional meaning beyond the schema. It fails to explain the query format or how to obtain an API key, which are critical for proper use.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search the National Library of Australia's Trove' clearly states the verb 'Search' and the resource 'Trove'. However, it does not differentiate from sibling tools like trove_get_work or trove_newspaper_article, but it is distinct in being a general search rather than specific retrieval.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like trove_get_work or trove_newspaper_article. The description is generic and does not specify usage context, prerequisites, or scenarios where this tool is preferred.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits like required permissions, rate limits, pagination, or read-only nature. The description carries full burden but fails to add context beyond the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with 10 words, no wasted words. It is front-loaded with the action and resource. However, it is very brief and could be expanded without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with two parameters, the description provides the core purpose. However, it lacks details about output (no output schema), pagination, and grouping concepts. With no annotations, this is minimally acceptable but not fully complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. The description does not explain the parameters api_key and org, leaving the agent to infer from names alone. The schema provides no descriptions either, so the tool definition lacks guidance on parameter semantics.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists all groups in a Turso organization. It uses a specific verb and resource, distinguishing it from sibling tools like turso_list_databases. However, it does not explicitly differentiate from other list tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, such as other Turso list operations. No prerequisites or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, authentication requirements, rate limits, or side effects. The agent is left to infer that this is a read operation from the name and description.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, which is appropriate for a simple tool. However, it lacks any additional structure or breakdown of parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's moderate complexity (3 parameters, no output schema), the description is too minimal. It does not specify what constitutes 'recent activity' (e.g., time frame), whether check-ins are from all users, or what the response contains. The agent may need to infer or experiment.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning beyond the parameter names and types. For example, 'limit' is not explained, and 'api_key' is present but not described as an authentication requirement.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('Get') and resource ('recent activity/check-ins for a beer'), which helps differentiate from sibling tools like 'untappd_get_beer' or 'untappd_search_beer'. However, the word 'activities' is somewhat ambiguous and could be more specific.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites, context, or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provide safety cues. The description omits that deletion is irreversible, potential side effects, or required permissions. For a destructive operation, more disclosure is needed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence with no redundancy, but it is too minimal and lacks necessary context. It earns its place but fails to inform adequately.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema exists, yet the description does not mention what the tool returns (e.g., confirmation, count). It also lacks information on error conditions, making it incomplete for a database delete operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% and the description only mentions 'key' generically. It adds no meaning to the four parameters (api_key, email, db_id, key), leaving them entirely self-documenting via the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Delete a key'), resource ('a key'), and target ('Upstash Redis database'), which distinguishes it from siblings like get and set operations.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., set, incr), no context on prerequisites or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. The description implies a read operation but does not disclose any behavioral traits such as authentication requirements, rate limits, or side effects. With no annotations, the description should provide more context.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with no wasted words. It is appropriately concise for a simple tool, though it could benefit from additional context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and 2 parameters with no description coverage, the description is very incomplete. It fails to describe the output, prerequisites, or any usage nuances.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the description adds no meaning beyond the schema. It does not explain the purpose of deploymentId or api_key, nor how they relate to the tool's function.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'details for a specific Vercel deployment', distinguishing it from sibling tools like vercel_list_deployments (lists many) and vercel_create_deployment (creates).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives. Does not mention that the deployment ID is required or that vercel_list_deployments might be used first to obtain it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behaviors beyond listing. It does not mention authentication, rate limits, or whether it lists all projects for the current user or globally.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with no output schema and no annotation, the description fails to explain return values, pagination, or any caveats. It is incomplete for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% and the description provides no information about 'limit' or 'api_key' parameters. The agent gets no help understanding how to use them.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states 'List all Vercel projects,' which is a specific verb and resource. Distinct from sibling tools like 'vercel_list_deployments' and 'vercel_create_deployment'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like 'vercel_list_deployments.' Does not mention scope, permissions, or context.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must disclose behavioral traits. It does not clarify that this is a read-only operation, nor does it mention rate limits, data freshness, or any side effects. The description is too minimal to inform safe usage.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. However, it is too brief given the lack of parameter and behavioral information, sacrificing completeness for brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema is provided, and the description does not hint at what the forecast return includes (e.g., temperature, conditions, units). For a 4-parameter tool, this is insufficient context for an agent to interpret results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage, and the description does not explain any parameters (e.g., latitude/longitude format, days range, timezone format). This forces the agent to infer or guess correct values.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it gets a weather forecast for a location and specifies the data source (Open-Meteo). It distinguishes from sibling tools like weather_current and weather_hourly by implying a multi-day forecast through the 'days' parameter, but could be more explicit about the time range.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., weather_current for current conditions, weather_hourly for hourly data). There are no exclusions or prerequisites mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It only uses the verb 'Get', implying a read operation, but adds no details about permissions, pagination, or side effects. Minimal transparency beyond the name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (9 words) and front-loaded with the action and resource. However, it is arguably too minimal, lacking any structural elements like bullet points or parameter context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (3 params, no output schema, no annotations), the description is severely incomplete. It does not explain authentication, return format, or the concept of a chart of accounts. Sibling tools exist but no comparative context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the description does not mention any parameters. The three parameters (type, access_token, tenant_id) are left completely unexplained, leaving the agent without guidance on how to use them correctly.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'chart of accounts', and the source 'from Xero'. It distinguishes this tool from sibling Xero tools like xero_invoices or xero_bank_transactions by specifying a unique data type.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus other Xero tools or under what conditions. The description does not mention prerequisites, alternatives, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must fully disclose behavioral traits. It only implies read-only access but omits details on authentication requirements, rate limits, error handling for invalid report types, or that dates might be required.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that front-loads the core purpose. However, it could include brief additional context without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 5 parameters, no output schema, and no annotations, the description is severely incomplete. It fails to explain required authentication, date format expectations, or how report_type values map to actual reports.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is only 20% (only 'report_type' has a description). The description adds no new parameter info, leaving the purpose of 'from_date', 'to_date', 'access_token', and 'tenant_id' unexplained.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get'), resource ('financial reports'), and source ('Xero'). It effectively distinguishes this tool from sibling Xero tools (e.g., xero_accounts, xero_invoices) which handle different data types.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus other Xero tools or when not to use it. For instance, it does not mention that report_type must be one of the specific options listed in the schema.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Get details' which implies read-only, but does not disclose error behavior (e.g., if ID not found), rate limits, authentication requirements (api_key is optional but not explained), or response format.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely short (one sentence), which is efficient but sacrifices necessary detail. It is front-loaded with the core purpose, but the lack of additional information makes it minimally viable rather than well-structured.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has no output schema and low parameter documentation, the description should provide more context about what 'details' are returned (e.g., name, address, rating, hours). It fails to do so, leaving the agent without expectations for the return value.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate. However, it only mentions business_id indirectly and does not explain the api_key parameter at all. The description adds no meaning beyond the parameter names, leaving users unclear about the api_key's purpose or when it is needed.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get details for a Yelp business by ID', using a specific verb and resource. It effectively distinguishes from sibling tools like yelp_search_businesses (search) and yelp_get_reviews (reviews), making it clear what this tool uniquely does.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is given on when to use this tool versus alternatives. For example, it does not mention that the business ID should be obtained from yelp_search_businesses first, or any prerequisites. The description lacks context for appropriate usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description must disclose behavior. It only states 'list available caption tracks' without explaining response format, authentication requirements (api_key is a parameter but not explained), or any limitations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, which is efficient but omits valuable context. It could be improved with a structured format including parameter hints.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description is insufficient. It does not clarify what a 'caption track' is, what the response contains, or how to use the api_key, leaving gaps for the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% and the description provides no information about the two parameters (api_key, video_id), leaving the agent without meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List', the resource 'available caption tracks', and the scope 'for a YouTube video', distinguishing it from other YouTube tools like get_video or search.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, no prerequisites or exclusions mentioned. The description does not clarify that 'list' means metadata only, not the actual captions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description only says 'look up' without disclosing behavioral traits such as authentication requirements (api_key), rate limits, or whether the lookup is read-only. This lack of transparency leaves the agent guessing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that is easy to parse. However, it is under-specified; the brevity sacrifices important context that could be added without much bloat.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (2 parameters, no output schema), the description is minimally adequate but lacks details on return format, authentication, and the scope of lookup (forward and reverse). It does not leverage the schema to provide a complete picture.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 50% description coverage (only 'q' is described). The description adds marginal value by indicating that 'q' can be a suburb name or postcode, but it does not clarify the 'api_key' parameter or its necessity. The schema itself already provides the same level of info for 'q'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('look up') and the resource ('Australian postcode or suburb'), which is specific and distinguishes it from sibling tools like auspost_delivery_times and auspost_track_parcel. However, it does not explicitly state that it supports both forward and reverse lookups, which would make it even clearer.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus other Australia Post tools. It does not mention prerequisites, limitations, or an alternative for different lookup scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It only states the basic function but does not disclose whether it's read-only, error behavior, rate limits, or authentication needs. The api_key parameter is present but not explained.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. It is front-loaded and to the point, but slightly under-specified for maximum utility.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read tool with no output schema, the description provides the core purpose but lacks details on response format, error handling, and authentication. It is adequate but not fully complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate. It does not add meaning beyond the schema—'playerTag' and 'api_key' are not explained in terms of format or purpose.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Get a Brawl Stars player) and the input (by tag). It differentiates from siblings like bs_club, making it distinct. However, it doesn't specify the expected format of the tag (e.g., with # prefix), which could cause confusion.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives like bs_club or other search tools. There is no mention of prerequisites, auth requirements, or situations where this tool is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It only says 'Search', implying read-only, but gives no details about authentication via api_key, rate limits, or the nature of the returned data. The behavior is opaque.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, which is efficient for a simple search tool. However, it could be slightly more structured without losing brevity, e.g., by hinting at required context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and numerous sibling tools, the description is incomplete. It does not explain return format, how to handle api_key, or what entity types are searchable. More detail is needed for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has three parameters with zero description coverage. The description adds no meaning to entityType, searchTerm, or api_key. An agent cannot infer valid values or constraints from the description alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states a specific action ('Search') and resource ('Destiny 2 manifest entities'). It distinguishes from siblings like bungie_get_manifest and bungie_search_player by targeting 'entities' rather than profiles or the manifest itself.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not specify what constitutes an 'entity', nor does it advise against using it for player or profile searches, which are covered by sibling tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full behavioral burden. It only states the basic function (calculate tip and total) but omits important details like rounding behavior, handling of missing optional parameters (e.g., split), or whether the total is per person or overall. This is insufficient for safe invocation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no fluff. It efficiently conveys the core purpose. However, it could be slightly expanded with parameter hints without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (3 params, no output schema, no annotations), the description should at minimum clarify the parameters and return value. It fails to do so, leaving the agent guessing about expected inputs and outputs. The description is not complete enough for reliable use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage, and the tool description provides no information about parameters. The agent does not learn what 'bill', 'tip_percent', or 'split' represent, their formats, or constraints. This is a critical gap for correct usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Calculate tip amount and total for a bill.' It uses a specific verb+resource, making it immediately understandable. Among sibling tools like calc_bmi or calc_compound_interest, this one is distinct in its function.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidelines are provided. The description does not specify when to use this tool vs. alternatives, nor does it mention any prerequisites or exclusions. The agent receives no context for decision-making.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It only states 'list all subscribers' and does not disclose pagination, rate limits, authentication requirements, or whether it is read-only.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that is too minimal. It lacks necessary detail and does not earn its place by providing value beyond the tool name.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 6 parameters, no output schema, and no annotations, the description is incomplete. It does not cover pagination, filtering, sorting, or output format, leaving the agent underspecified.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Input schema has 6 parameters with 50% description coverage. The tool description adds no meaning beyond the schema; it does not explain how to use page, to, sort_field, or from parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it lists all subscribers in a ConvertKit account, with a specific verb and resource. It distinguishes from sibling tools like ck_add_subscriber and ck_tag_subscriber.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives, no prerequisites or exclusions mentioned. The description is too brief to help an agent decide between this and other ConvertKit tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It does not disclose behavioral traits such as whether the operation is read-only, authentication requirements, rate limits, or the nature of the response. The minimal description offers no insight beyond the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very short (one sentence) and front-loaded with the key action. However, it is so brief that it sacrifices essential details. It earns a 4 for efficiency but loses a point for being too terse.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has four parameters (two required), no output schema, and no annotations. The description does not explain the output format, how to structure the few-shot examples, or what model options exist. Given the complexity of few-shot classification, the description is incomplete and lacks necessary context for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema already describes 'inputs' and 'examples' as JSON arrays, but the description adds no further meaning. It does not explain what 'api_key' or 'model' should contain, nor does it elaborate on the format of the few-shot examples. With 50% schema coverage, the description fails to compensate for the undocumented parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Classify texts into categories using Cohere Classify with few-shot examples.' It specifies the verb 'classify' and the resource 'texts', and mentions a distinguishing feature (few-shot examples). Among sibling tools like cohere_chat and cohere_embed, this uniquely identifies the classification capability.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description only implies usage with 'few-shot examples' but provides no explicit guidance on when to use this tool versus alternatives (e.g., cohere_generate or cohere_rerank). It does not mention prerequisites like needing an API key or cite any context for appropriate use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description lacks behavioral details beyond a basic action. It does not mention authentication requirements (despite an optional api_key parameter), side effects (none implied), or output format. With no annotations to compensate, the agent cannot assess safety or prerequisites.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    While the description is a single sentence with no wasted words, it is under-specified. Conciseness should not come at the expense of necessary information; the tool description should include usage context, parameter semantics, and behavioral notes, which are missing.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of annotations and output schema, the description should fully explain the tool's behavior and results. It fails to mention what a 'model' listing contains (IDs, names?), or whether pagination exists. The description is insufficient for an agent to use effectively without external knowledge.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has one parameter (api_key) with no description, and the description does not mention it. The agent is left guessing whether an API key is needed and how it might affect the results. The parameter is essential for context, but the description provides no semantic value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states 'List all available Cohere models,' which is a clear verb+resource combination. It differentiates from sibling Cohere tools (e.g., cohere_chat, cohere_generate) by specifying the listing action, and from other model listing tools (e.g., openai_list_models) by specifying Cohere.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., for selecting a model before calling cohere_chat). The description does not explain prerequisites, the read-only nature, or that results can be used in other Cohere calls. This forces the agent to infer usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are available. The description only says 'Create', indicating a write operation, but lacks details on side effects, required permissions, error handling (e.g., invalid image URL), or any consequences of the action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness2/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is too minimal for a tool with 7 parameters. It lacks structure and essential information, making it under-specified rather than concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema exists, and the description provides no information about return values. With 7 parameters and low schema coverage, the description fails to make the tool usable without additional external knowledge.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 43% (3 of 7 parameters described). The description does not add meaning beyond the schema; it only mentions 'image URL' (matching media_source_url). It fails to explain optional parameters like title, description, or access_token.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Create'), the resource ('Pinterest pin'), and the source ('from an image URL'). This directly differentiates it from sibling tools like list_pinterest_pins (listing) and search_pinterest_pins (searching).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus other Pinterest tools, such as when to create vs. update pins, or any prerequisites (e.g., needing a board). The description is silent on usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral disclosure. It states only that the tool gets info, implying a read operation, but omits details like rate limits, data freshness, or authentication requirements.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that front-loads the purpose. No unnecessary words, but it could be slightly expanded for clarity without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one parameter and no output schema, the description provides the essential purpose and source. However, it lacks details on the output structure or what 'detailed info' encompasses, leaving some incompleteness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single parameter 'id' has no schema description (0% coverage). The description does not explain that 'id' refers to a CoinGecko coin ID, leaving ambiguity about what values to provide.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets detailed info for a cryptocurrency from CoinGecko, using a specific verb and resource. However, it does not distinguish from sibling tools like crypto_price or crypto_coin_history, which also retrieve cryptocurrency data.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description lacks context about preferred scenarios or exclusions, which is problematic given the many related sibling tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as authentication requirements, rate limits, error handling for invalid IDs, or any side effects. The burden falls on the description, but it remains minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is one short sentence (6 words) and is front-loaded with the purpose. However, it is too terse; it could include more context without being verbose. It earns a neutral score for not being wasteful but lacking substance.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple getter with one parameter, the description adequately states the core action. However, with no output schema, it does not hint at what the response contains (e.g., artist details like name, genre). It is barely sufficient.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage for the 'id' parameter. The description does not explain where to find the ID, its format (e.g., numeric), or any constraints. It fails to compensate for the schema's lack of detail.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Get') and resource ('a Deezer artist') with the method ('by ID'). It clearly distinguishes from sibling tools like deezer_search (searching) and deezer_get_album/get_track (other resource types).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It doesn't mention that a Deezer artist ID is needed (obtained from search) or that deezer_search should be used if the ID is unknown.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral disclosure. It only implies a read-only search operation but does not mention authentication requirements, rate limits, pagination behavior, or any potential side effects. The description is too minimal to adequately inform the agent.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of six words, efficiently conveying the core action and target. It is front-loaded and contains no superfluous information, achieving maximum conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of annotations, output schema, and the presence of sibling tools, the description is incomplete. It does not explain return values, pagination, or how to interpret results. The tool is simple, but a more complete description would include guidance on search behavior and result structure.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has only one parameter with a description (type), and schema description coverage is low at 33%. The description lists the entity types ('tracks, artists, or albums') which loosely corresponds to the type parameter, but does not explain the purpose of the 'q' or 'limit' parameters. More elaboration on how to use these parameters would be needed.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Search') and the resource ('Deezer for tracks, artists, or albums'). It is specific about the entity types covered, which helps differentiate from sibling tools like deezer_search_playlist that focus on playlists. However, it does not explicitly differentiate from deezer_chart or deezer_get_* tools, but the verb and resource combination is clear.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as deezer_get_album, deezer_get_artist, or deezer_search_playlist. There is no mention of prerequisites, context, or when not to use this tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description carries the full burden. It fails to disclose authentication requirements (api_key), rate limits, or behavior on missing artists. The minimal description adds no behavioral context beyond the basic operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no redundancy. However, it is overly brief at the expense of necessary detail, limiting its usefulness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is incomplete for a simple retrieval tool. It lacks return value information (no output schema), parameter descriptions, and usage context. The agent cannot determine what data to expect from the response.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema coverage, the description must compensate but does not. It mentions 'by ID' but does not explain the 'artist_id' parameter or its format, and completely ignores the 'api_key' parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get'), the resource ('Discogs artist'), and the method ('by ID'). It effectively distinguishes from sibling tools like 'discogs_search_artists' which search by name.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus other Discogs tools (e.g., search vs. get by ID). The description does not mention alternatives or prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description bears full responsibility for behavioral disclosure. It only states the basic purpose without revealing traits like scope of search (e.g., all history vs. recent), required permissions, pagination, or how results are returned.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence. However, it could benefit from additional structured information (e.g., what parameters control) without becoming verbose. It earns a 4 for being to the point but lacking structure.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters, no output schema, and no param descriptions, the description is too minimal to guide an agent effectively. Missing details like search criteria (by content, author, channel), result format, and limits make it incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain what any of the 5 parameters (bot_token, guild_id, content, author_id, channel_id) mean. While parameter names are somewhat self-explanatory, the description adds no semantic value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Search messages in a Discord guild' clearly states the verb (search), resource (messages), and scope (Discord guild). It effectively distinguishes from sibling tools like discord_read, discord_channels, etc., which serve different functions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as discord_read for reading messages or discord_channels for listing channels. No context about prerequisites or exclusions is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral disclosure. It fails to mention rate limits, authentication workflow (though client_id/client_secret are in schema), pagination behavior, or any side effects. The description is too brief to inform the agent about safety or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, front-loaded with the core action. However, it is too brief, sacrificing completeness for brevity. It does not earn its place by providing essential guidance that the schema lacks.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 9 parameters, no output schema, and multiple sibling tools, the description is inadequate. It fails to explain search behavior, filter usage, pagination, or result format. The agent would lack sufficient context to use the tool effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is high (89%), so the schema itself explains most parameters. The description adds no extra meaning beyond listing the action. Baseline of 3 is appropriate as it neither improves nor detracts from the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Search eBay listings via the Browse API', clearly specifying the action (search) and resource (eBay listings). It is specific but does not distinguish itself from sibling tools like ebay_get_item or ebay_get_categories, which would warrant a 5.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use ebay_search versus alternatives. The description does not mention any context, prerequisites (beyond the required parameters), or situations where other tools would be more appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description only states 'Get' which implies read-only. It fails to disclose pagination behavior, response format, or any side effects. Minimal behavioral context beyond the verb.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with clear verb and resource. No redundant information; front-loaded with action. Excellent conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description is incomplete. It does not detail the response structure, pagination support, or error handling, which are critical for an agent to use the tool effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is low (25%), with only voice_id having a description. The tool description does not explain api_key usage, page_size defaults, or start_after_history_item_id for pagination, leaving key parameters ambiguous.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves TTS generation history, differentiating it from siblings like elevenlabs_text_to_speech (generates speech) and elevenlabs_list_voices (lists voices). However, it does not specify scope (e.g., all history, paginated) or account details.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as elevenlabs_get_models or elevenlabs_get_voice. It lacks explicit context for when history retrieval is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. Only states the tool lists models and languages, with no additional behavioral context (e.g., authentication requirements, rate limits, or output format).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence efficiently communicates the core action. No wasted words, though it could be slightly more structured with explicit parameter hints.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 1 parameter, no output schema, and no annotations, the description is insufficient. It omits essential details like what information is returned for each model (e.g., model ID, name) and any usage prerequisites.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 1 required parameter (api_key) with 0% description coverage. The description does not explain the parameter's purpose or how to use it, failing to add value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'List available ElevenLabs TTS models and their supported languages.' It uses a specific verb ('List') and resource ('models'), and distinguishes the tool from siblings like elevenlabs_text_to_speech or elevenlabs_list_voices.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. Lacks context such as 'Use this to discover available models before generating speech' or any exclusion criteria.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits such as permanence of deletion, side effects, or required permissions. For a destructive tool, this is a significant gap.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence with no wasted words, but it is overly minimal and lacks important details, bordering on under-specification.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no annotations, no output schema, and 4 parameters mostly undocumented, the description fails to provide sufficient context for correct tool usage, especially for a destructive operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 4 parameters (uid, folder, email, password) with no descriptions, and the description only mentions uid. The purpose of folder, email, and password is left entirely unexplained.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Delete), the resource (email), and the identifier (UID). It is specific and distinguishes from sibling tools like email_get or email_send.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies that you need the UID to delete, but provides no explicit guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations present, the description bears full responsibility for behavioral disclosure. It only states that the tool retrieves messages, with no mention of read-only nature, authentication, rate limits, data freshness, or response characteristics. This is insufficient for safe invocation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no superfluous words. However, its brevity borders on under-specification, but given the tool's simplicity, it is appropriately concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite the tool having only two parameters and no output schema, the description lacks essential context such as the structure of the returned data, any time or session constraints, and how this tool fits among the F1 siblings. More context would improve the agent's ability to use it correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage, meaning the schema itself provides no explanations for parameters. The description adds no additional meaning to 'session_key' or 'driver_number', failing to clarify their purpose (e.g., what a session key represents or how to obtain a driver number).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states that the tool retrieves Formula 1 team radio messages from the OpenF1 data source, using a specific verb ('Get') and resource ('team radio messages'). This distinguishes it from sibling F1 tools that retrieve other data types (e.g., car data, drivers, laps).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus the many sibling F1 tools (e.g., f1_car_data, f1_weather). The description does not mention prerequisites, typical use cases, or alternative tools, leaving the agent to infer usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the basic function without mentioning authentication requirements, rate limits, read-only nature, or any other behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no fluff. While efficient, it could provide slightly more information without sacrificing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and the presence of sibling tools, the description is incomplete. It fails to explain the structure of comments, how to obtain a file key, or any prerequisites, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no explanation for the two required parameters (personal_access_token, file_key). The agent must infer their meaning from names alone, which is insufficient.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and the resource ('all comments on a Figma file'), making the tool's purpose unambiguous. It effectively distinguishes this from sibling tools like figma_get_file or figma_post_comment.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as figma_get_file (which may include comments) or figma_post_comment. The description lacks context for usage decisions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must cover behavioral traits. It does not disclose whether the tool is read-only, required permissions, error handling, rate limits, or any side effects. 'Get' implies reading, but this is not explicit.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words, but it is too minimal and lacks structure. It could front-load key details like 'Read-only retrieval of a Figma node by ID'.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and three required parameters, the description is insufficient. It does not explain what the node data includes, how to interpret the result, or error conditions. For a node retrieval tool, more context is needed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 33% (only node_id has a description). The tool description adds no additional meaning beyond the schema. It does not explain personal_access_token or file_key, nor does it clarify the node_id format beyond the schema's example.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get a specific node by ID within a Figma file' clearly states the verb (Get), resource (specific node), and context (within a Figma file), distinguishing it from sibling tools like figma_get_file (gets entire file) or figma_get_components (lists components).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like figma_get_file or figma_get_components. There is no mention of prerequisites, context, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behavioral traits like pagination, error handling, or rate limits, but it only states the basic function.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no wasted words, but it could be expanded slightly without losing efficiency.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and annotations, the description fails to explain what the standings return looks like, how to paginate, or how to obtain a league_id, making it incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning to the parameters; it does not explain what league_id represents or what the page parameter does, despite 0% schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and the resource ('FPL classic league standings'), distinguishing it from sibling FPL tools like fpl_player or fpl_fixtures.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus other FPL tools, nor are there any prerequisites or context for using league_id or page parameters.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description must cover behavioral traits. It only states 'Get details' without mentioning authentication requirements, rate limits, data freshness, or what details are returned. Insufficient for a mutation-free tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    One concise sentence with clear purpose. Minimal but effective for a straightforward tool. No wasted words, though could include more context without being verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description fails to specify what 'details' are returned or any prerequisites for the tool. Leaves agent guessing about the response structure.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and description adds no meaning to parameters 'applicationNumber' or 'api_key'. Does not explain that applicationNumber is the trademark ID or that api_key is optional/needed for authentication.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'Get', resource 'Australian trademark', and implies specificity via 'for a specific'. Distinguishes from sibling 'search_trademarks' which is for searching.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool vs. alternatives like search_trademarks. Only implies usage when a specific application number is known, but does not state this explicitly or provide exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Without annotations, the description carries the full burden. It only indicates a read operation ('List') but does not disclose authentication requirements, rate limits, pagination, or any other behavioral traits. The input schema suggests authentication is needed, but the description fails to mention this.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that efficiently conveys the tool's purpose. There is no extraneous information, though it could be slightly more structured to include parameter or behavior hints.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has no output schema, no annotations, and two parameters with 0% schema coverage, the description is insufficient. It omits authentication context, return format, and any constraints. A complete description would at least note that authentication credentials are required and what the response contains.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning for either parameter (client_id, client_secret). The agent receives no guidance on what these parameters represent or how to use them, relying solely on the schema which lacks descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List' and the resource 'all game genres' from IGDB. It is specific and distinguishes itself from sibling tools like igdb_list_platforms, igdb_search_games, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. The description does not mention any prerequisites, context, or exclusions. The agent is left without direction on whether to choose this tool over other igdb tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description bears full responsibility for disclosing behavior. It only states what it does, omitting any details on authentication, rate limits, pagination, or response format.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise (one sentence), which is front-loaded but lacks necessary detail. It prioritizes brevity over completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 4 parameters including authentication, no output schema, and no annotations, the description is severely incomplete. It fails to explain how to use authentication, pagination, or what the result looks like.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 25% (only limit has a description). The tool description does not elaborate on any parameters, especially the required client_id and client_secret, leaving their purpose unclear.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List gaming platforms from IGDB' clearly specifies the action (list) and the resource (gaming platforms) plus the datasource (IGDB). It is distinct from sibling tools like igdb_search_games or igdb_list_genres.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden but only states the basic operation. It does not disclose side effects, data limits, authentication requirements (api_key parameter not explained), or whether the tool is read-only. Minimal transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that front-loads the action. It is efficient but at the cost of omitting necessary details, making it slightly under-informative for its brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 3 parameters, no output schema, and no annotations, the description is too sparse. It fails to provide context about input constraints, return format, or required authentication, making it inadequate for agent decision-making.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain any parameters (artist, limit, api_key). The agent gains no additional meaning beyond the schema's type definitions, which are insufficient for proper usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get similar artists on Last.fm.' clearly states the verb (get) and resource (similar artists) on a specific platform, distinguishing it from sibling tools like lastfm_artist_info or lastfm_search_artists.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as lastfm_artist_info or lastfm_search_artists. There is no mention of prerequisites, scenarios, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral disclosure. It does not mention read-only nature, authentication requirements (api_key), rate limits, or output format. The basic purpose is stated, but critical behavioral traits are missing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence that front-loads the purpose. It is concise and contains no wasted words, but could benefit from additional context without sacrificing brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple (3 params, no output schema), but the description is insufficient. It does not cover how to use parameters, expected inputs, or what the output contains. Given the low schema coverage and lack of annotations, the description should provide more complete context for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no information about parameters. It does not explain 'artist', 'limit', or 'api_key', leaving their roles and constraints entirely to the schema, which has no descriptions. The description fails to compensate for the coverage gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the specific action ('Get'), resource ('top tracks'), and context ('for an artist on Last.fm'). It distinguishes from sibling tools like lastfm_artist_info (artist info) and lastfm_search_artists (search artists), making the tool's purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as lastfm_chart_top_tracks. It does not mention prerequisites, exclusions, or context of use, leaving the agent to infer from the name alone.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description only says 'Search LEGO parts by name.' Lacks details on output format, pagination, authentication needs (api_key), or match behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise but misses necessary details; borderline under-specification rather than effective conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Insufficient for a search tool with 2 params and no output schema; no mention of result format, pagination, or api_key usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. Description implicitly covers 'search' parameter by mentioning 'by name' but omits explanation for 'api_key' parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the verb 'Search', resource 'LEGO parts', and basis 'by name'. Distinguishes from sibling tools like lego_get_set and lego_set_parts.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get'), the resource ('LINE group'), and the specific data returned ('name and picture URL'). It differentiates well from sibling LINE tools like line_get_profile and line_broadcast.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus other LINE tools, no prerequisites or context for usage. The description is purely functional.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral transparency. It only states the basic function, without disclosing that the 'user_uri' can be auto-resolved, that the 'active' filter exists, or any pagination or authentication details beyond implying the user is authenticated.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that front-loads the action and resource. Every word is purposeful with no waste.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters, no output schema, and no annotations, the description is too brief. It does not explain the return format, why you would use this over sibling tools, or how parameters like 'count' work.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no parameter semantics beyond the input schema. Schema description coverage is 50% (descriptions for user_uri and active, but not for count and api_key). The tool's description does not compensate for this gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List event types for the authenticated Calendly user' clearly states the action (list), resource (event types), and scope (authenticated user). It is specific but does not differentiate from sibling tools like 'list_calendly_events' which lists events rather than event types.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as 'list_calendly_events' or 'get_calendly_event'. No context, exclusions, or usage scenarios are mentioned.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It only says 'create' without disclosing behavioral traits such as success/error handling, permissions needed, or side effects (e.g., does it create a draft or send immediately?). Minimal transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but lacks substance. It is not bloated, but it also fails to add value. Score 3: adequate but borderline under-specified.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (6 parameters, no output schema, no annotations), the description is insufficient. It does not explain the return value, campaign type implications, or validation behavior. A more complete description would aid agent decision-making.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description adds no additional meaning beyond the schema properties. It does not explain defaults, relationships between parameters, or formatting requirements. Score 3 as schema already covers parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Create a new Mailchimp email campaign' clearly states the verb and resource. The name and sibling tools (e.g., mailchimp_add_member, mailchimp_get_campaign) provide implicit differentiation, though the description itself does not explicitly distinguish from siblings. Score 4 for clear but not fully differentiated.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance provided on when to use this tool versus alternatives (e.g., when to create a campaign vs. add a member). No prerequisites, context, or exclusions are mentioned. Score 2 for no usage guidance.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but only mentions fetching data for a date range. No information on rate limits, pagination, response format, or whether events require filtering.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Description is a single sentence, which is concise but under-informative for an 8-parameter tool. Could include more details without being verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, no annotations, and the description does not explain return values, aggregation options, or how to interpret the data. Incomplete for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 100% description coverage, so description adds no extra parameter meaning beyond the schema's own descriptions. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the action (Get) and resource (Mixpanel event analytics data) with a date range scope. It distinguishes from siblings like mixpanel_export_data and mixpanel_get_funnels, though it doesn't explicitly differentiate.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., mixpanel_export_data, mixpanel_get_funnels). Lacks context on prerequisites or use cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must convey behavioral traits, but it only states the function. It does not mention read-only nature, data freshness, rate limits, or authentication requirements (the latter is implicit from required parameters).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (one sentence) but lacks structure. While it is not verbose, it fails to provide any structured details that would aid an agent in using the tool effectively.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (9 parameters, no output schema, no annotations), the description is insufficient. It does not describe the output format, retention calculation details, or how the parameters interact, leaving significant gaps for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with adequate parameter descriptions. The description adds no additional meaning beyond what is already in the schema, so it meets the baseline expectation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves user retention analytics from Mixpanel, which distinguishes it from sibling tools that deal with events, funnels, or raw data. However, it could be more specific about the type of retention data (e.g., cohort retention).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like mixpanel_get_funnels or mixpanel_get_events. The agent must infer from the tool name and sibling context, which is insufficient.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description lacks behavioral details such as whether the operation is read-only or destructive, error handling, rate limits, or idempotency. The description carries the full burden but provides no extra context beyond the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that front-loads the core purpose. However, it is overly minimal for a tool with 6 parameters and no annotations, making it less useful despite its brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (6 parameters, 5 required, no output schema, no annotations), the description is severely incomplete. It omits essential information about parameter usage, return values, and behavioral constraints, leaving significant gaps for an AI agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With schema description coverage at only 33%, the description does not add meaning for the 4 undocumented parameters (api_key, project_id, branch_id, endpoint_id). It fails to clarify their roles, and the existing schema descriptions for query and database_name are minimal.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Execute a SQL query' and the target 'against a Neon database endpoint'. It effectively distinguishes from sibling tools like neon_create_branch or neon_list_projects by specifying the core function.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of scenarios, prerequisites, or exclusions, leaving the agent to infer usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must convey all behavioral traits. It fails to disclose authentication requirements, rate limits, side effects, or the fact that payment processing is involved. The minimal description does not compensate for the lack of annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise, consisting of a single sentence. While concise, it lacks sufficient detail; it could be expanded slightly to add more context without being verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity of 7 parameters including authentication credentials for a payment service, the description is incomplete. It does not mention authentication, sandbox usage, or any operational details. No output schema exists to compensate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description does not add any additional meaning beyond what the schema already provides for each parameter, so no extra credit.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states that the tool can 'Create or retrieve a PayPal order', which specifies the verb and resource. However, there are no sibling PayPal tools, so no differentiation is needed, but it doesn't add extra clarity beyond the name.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide any guidance on when to use this tool versus alternatives, nor does it explain the distinction between create and retrieve actions beyond what is in the schema. No context for usage is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description must carry the full burden of behavioral disclosure. It only implies a read operation ('Get directions') but omits important details like authentication requirements, rate limits, or data freshness.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, making it concise and front-loaded. However, it may be too brief; a bit more detail could improve effectiveness without sacrificing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (2 params, no output schema), the description is inadequately thin. With 0% parameter coverage, it should at least explain the purpose of each parameter and the expected return.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the parameters. 'route_id' and 'api_key' are unexplained, leaving the agent without clarity on their roles or formats.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('Get') and resource ('directions for a PTV route'), enabling an agent to understand the tool's purpose. It distinguishes from sibling tools like ptv_departures, ptv_disruptions, ptv_search, and ptv_stops_on_route, which cover different functionalities.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives or on prerequisites. The description does not mention any exclusions or context for usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description fails to disclose any behavioral traits (e.g., authorization, rate limits, response format). The minimal description does not add value beyond the purpose.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with no waste. It is appropriately sized for its simplicity, though could be more structured with additional details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description is too bare. It does not explain the response, pagination, or error handling, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the tool description does not explain what 'tag' or 'limit' mean, e.g., expected format for tag or how limit affects results. No useful parameter semantics.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get radio stations by genre tag' clearly states the action (get), resource (radio stations), and filtering criterion (genre tag). It distinguishes from sibling tools like radio_by_country, radio_search, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as radio_search or radio_by_country. The description merely states what it does without context for selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must bear the full burden. It states the tool generates a random number within a range but does not explain key behaviors like whether min/max are inclusive, whether the output is integer or float (despite a boolean integer parameter), or how the count parameter affects output. Missing edge-case details.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 7 words, which is concise but too minimal. It could be expanded to include parameter behavior or usage context without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters (including non-obvious ones like count and integer), no output schema, and no annotations, the description is severely incomplete. It fails to specify return format, parameter semantics, or behavioral guarantees.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description adds minimal meaning beyond the schema. It vaguely implies min/max as range boundaries but does not explain the count or integer parameters. The schema lists them without descriptions, and the description does not compensate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Generate a random number within a range' clearly states the action (generate) and the resource (random number). It distinguishes itself from sibling tools like random_string or random_roll_dice.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., random_roll_dice, random_lorem_ipsum). It does not mention when not to use it or any prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, and the description does not disclose behavioral traits such as whether it returns individual die results or just a sum, or the randomness quality. The schema parameter hint ('e.g. 2d6') is not in the description, so the description itself lacks transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise at two words, but it may be too terse, sacrificing completeness for brevity. It is front-loaded but lacks structure to convey essential information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity of the tool and no output schema, the description should at least mention the return format or the standard dice notation. It fails to provide complete context, especially compared to other random tools with more detailed descriptions.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema description for the parameter 'dice' includes examples ('2d6, 1d20'), providing meaning beyond the type. Since schema coverage is 100%, the description does not need to add much, but it adds nothing. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Roll dice.' clearly states the verb and resource, and it distinguishes itself from sibling tools like random_flip_coin or random_number by specifying dice rolling. However, it is very terse and could be more specific about what 'dice' means.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description implies it is for dice rolls but does not explain when it is appropriate or when to use other random tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but only says 'Get details' without specifying what details are returned, whether it is read-only, or any auth or rate limit requirements. The behavioral traits of the tool are entirely opaque.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. It is concise, but it could benefit from additional detail without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has no output schema, so the description should explain what 'details' are returned. It does not mention response fields, pagination, or any side effects. Given the low complexity, the description is insufficient for an agent to fully understand the tool's behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (only `service_id` has a description in the schema). The tool description adds no extra meaning for either parameter. The `api_key` parameter is not explained at all, and the description does not clarify the format or source of `service_id` beyond what the schema already provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get details for a specific Render service,' which is a specific verb+resource combination. It distinguishes itself from sibling tools like `render_list_services` by implying a single service lookup through the use of a service ID.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like `render_list_services` or `render_trigger_deploy`. The description lacks any context about prerequisites, such as needing a service ID, or scenarios where this tool is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Without annotations, the description must convey behavioral traits. It states that the tool lists environment variables, implying a read operation, but does not mention whether values are shown, if any authentication is required (api_key hint), or if there are any limitations or side effects. This leaves key gaps for an agent.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, which is efficient. However, its brevity comes at the cost of completeness; a slightly longer but still concise description could include parameter or usage hints. It scores well for structure but not perfectly.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has two parameters with zero schema descriptions, no annotations, and siblings with overlapping contexts, the description fails to be complete. It does not clarify what the list returns, how parameters are used, or any constraints, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description should explain parameter meaning. It does not mention api_key or service_id at all. The agent receives no context beyond the schema field names, which is insufficient for correct invocation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List environment variables for a Render service.' clearly states the verb (List) and the resource (environment variables for a Render service). This distinguishes it from sibling tools like render_list_services or render_set_env_var, which have different purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidelines are provided. The description does not indicate when to use this tool versus alternatives such as render_get_service (which might include environment variables) or render_set_env_var (for modifying). It also lacks prerequisites like needing a valid service_id.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; the description only says 'Cancel' with no details on side effects (e.g., if cancellation is immediate, if results are lost, or billing impact). Minimal behavioral disclosure.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no fluff or repetition. However, it is overly concise, omitting critical parameter and behavioral information, so it does not earn the top score.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Simple tool with 2 required parameters and no output schema. The description lacks parameter details and return value expectations, making it incomplete for reliable use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% (api_token, prediction_id have no descriptions). The description adds no meaning to the parameters, failing to explain their purpose or format.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Cancel' and the resource 'running Replicate prediction,' distinguishing it from siblings like create_prediction, get_prediction, or list_predictions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., letting a prediction finish). The description does not mention prerequisites or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description only says 'Fetch the status', which is a read operation, but offers no details about side effects, idempotency, or what the status response contains. The cryptic second sentence suggests the tool may be incomplete, further reducing transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The first sentence is clear, but the second sentence is cryptic and unhelpful, adding confusion without earning its place. The description could be more concise and focused.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema, annotations, and nested objects, the description should provide more context about the status response and potential errors. It fails to give a complete picture, especially with the placeholder note.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema already documents the run_id parameter. The description adds no extra semantic value beyond what the schema provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool fetches the status of a SEOPass run, distinguishing it from siblings like seopass_run. However, the cryptic second sentence 'Chunk 1 reserves the tool shape; persistence lands later.' introduces ambiguity about the tool's readiness and purpose.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives. The parameter description hints that run_id comes from seopass_run, but the description itself does not state prerequisites or contrast with sibling tools like seopass_run.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description bears full responsibility but only states the basic operation. It does not disclose whether the tool is read-only (though implicit), what happens on error (e.g., invalid token or artist ID), or any rate limits or response size.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence containing essential verb and resource. No fluff; highly concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and 0% schema coverage, the description is critically incomplete. It does not specify return format, errors, or authentication details beyond the schema. Agent cannot fully predict behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% parameter description coverage, and the description adds no explanation for 'artist_id' or 'bearer_token'. The meaning of artist_id (Spotify ID format) and authentication requirement are left entirely to the schema, which provides no help.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'Get' and resource 'metadata and follower count for a Spotify artist', distinguishing it from sibling tools like spotify_get_album or spotify_get_track. No ambiguity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives such as spotify_search (to find artist ID) or other artist endpoints from different services. No prerequisites or context for usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the full burden. It only states 'Get', implying a read operation, but does not disclose authentication requirements (bearer_token is required), rate limits, or any side effects. The description fails to add behavioral context beyond the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single 14-word sentence, concise and front-loaded with the core purpose. However, it sacrifices key details like parameters and authentication, which prevents a higher score.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description is incomplete. It does not explain how to obtain a track_id, mention authentication, handle errors, or describe the output format. Important context for a tool with two required parameters is missing.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not mention either of the two required parameters (bearer_token, track_id). It does not add any meaning beyond the schema, leaving the agent to infer usage from parameter names alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'audio analysis features (danceability, energy, tempo, etc.) for a Spotify track'. It specifies the kind of data and provides examples, distinguishing it from sibling tools like spotify_get_track which returns metadata.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description offers no guidance on when to use this tool versus alternatives, such as when to prefer this over spotify_get_track or spotify_get_recommendations. No exclusions or context for usage is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description must disclose behavioral traits. Only says 'List' (read hint), but no info on pagination, rate limits, token requirements, or any side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no fluff. But under-specified for a tool with 4 parameters and no output schema. Could add more value without being verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Lacks crucial context: no output schema, no return value description, no authentication details, no pagination info. Incomplete for correct usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 4 parameters with only 25% coverage (types described). Description adds no parameter details beyond listing object types; access_token, cursor, and limit are unexplained.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states verb 'List' and resource 'Square catalog objects' with examples (items, categories, taxes). Distinguishes from sibling tool 'square_catalog_search' by implying listing vs searching.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use vs alternatives. Sibling 'square_catalog_search' suggests a search variant, but no when-to-use or when-not-to-use context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits beyond the basic action. Authentication requirements, rate limits, side effects of creation (e.g., idempotency) are not mentioned, despite the schema including an idempotency_key parameter.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise with only five words, which is efficient but at the expense of necessary detail. It earns its place by being short, but lacks structure and substance.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity of the tool (11 parameters, no output schema, no annotations), the description is severely incomplete. It fails to explain required fields for creation, authentication, or the return format, leaving major gaps for an AI agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is low at 45%, and the description adds no additional meaning to parameters beyond what is already in the schema. For instance, it does not explain the amount_money object or the roles of customer_id and note.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List or create Square payments' clearly states the verb-resource (list/create payments) and distinguishes from sibling tools like square_catalog_list and square_customers, which deal with catalog and customer data respectively.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives or when to use list vs create. There is no mention of prerequisites or context, leaving the agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full responsibility for behavioral disclosure. It fails to mention pagination, rate limits, authentication requirements, or the format of returned data (e.g., list of movie objects). The minimal statement provides almost no operational context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no extraneous words. It is concise and straight to the point, though it could benefit from a bit more detail without sacrificing brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with two parameters and no output schema, the description is incomplete. It omits details about the result structure, pagination behavior, and whether api_key is required. A complete description would address these gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning no parameter descriptions exist in the schema. The description adds no meaning to the parameters 'page' and 'api_key', leaving the agent unaware of their purpose or constraints (e.g., api_key likely required but not indicated).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get movies currently in theaters from TMDB.' It uses a specific verb ('Get') and a distinct resource ('movies currently in theaters'), which distinguishes it from sibling TMDB tools like tmdb_search_movies or tmdb_trending.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description lacks any guidance on when to use this tool versus alternatives. No mention of use cases, prerequisites, or exclusions. For example, it does not indicate that searching movies by query should use tmdb_search_movies instead.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose any behavioral traits such as authentication requirements, pagination behavior, or output format. The agent learns nothing beyond the basic purpose.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise at one sentence with no extra words. However, it could include a brief parameter hint without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of annotations, output schema, and parameter documentation, the description is insufficient. It does not explain what the tool returns, pagination, or authentication needs.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description should clarify the purpose of 'page' and 'api_key' parameters. It does not, leaving the agent without meaningful context for using these inputs.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'upcoming movies' from TMDB. It is specific and distinct from sibling tools like tmdb_now_playing or tmdb_search_movies.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The user must infer based on the name and sibling tool names, but no explicit context or exclusions are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits beyond the basic operation. It does not explicitly state that the tool is read-only, nor does it mention potential failure conditions or authentication needs.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no extraneous information. However, it could be slightly more informative without sacrificing brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and low parameter coverage, the description is insufficiently complete. It does not describe the response format or indicate that the tool returns venue details; it only states the action without context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description does not explain either parameter (id, api_key). With 0% schema description coverage, the description should add meaning to the parameters, but it offers nothing beyond the schema names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get details for a specific Ticketmaster venue' clearly states the verb (Get) and resource (details for a specific venue). It distinguishes itself from sibling tools like tm_search_venues (search) and other venue tools from different APIs.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and 0% schema coverage, the description fails to specify what the tool returns (list of projects? fields?), how to authenticate, or any pagination behavior. It is incomplete for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description should compensate but only mentions 'workspace' in the purpose text. It does not explain what workspace_id represents (e.g., Toggl workspace ID) or when api_key is needed, thereby adding minimal value beyond property names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and resource ('Toggl projects') with scope ('for a workspace'), distinguishing it from sibling tools like toggl_time_entries or toggl_create_time_entry.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden. It does not disclose pagination behavior, rate limits, or whether the list is complete or truncated. The read-only nature is implied but not explicit.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that is concise and front-loaded. However, it is overly brief and omits important context, so it does not fully earn its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 6 parameters, no output schema, and no annotations, the description is insufficient. It does not explain return values, pagination, or authentication details beyond what is in the schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema description coverage is only 17% (only status has a description). The tool description adds no information about parameters such as account_sid, auth_token, to, from, or page_size, leaving the agent to guess their roles.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists both outbound and inbound calls on a Twilio account, using a specific verb and resource. This distinguishes it from sibling tools like twilio_list_messages and twilio_make_call.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with only two parameters and no output schema, the description is too sparse. It fails to specify what 'details' are returned, and it does not provide enough context for the agent to differentiate this tool from similar ones or understand the expected output.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description provides no explanation of the parameters. It does not clarify what 'brewery_id' represents or how to obtain it, nor does it describe the role of 'api_key'. The agent must rely solely on the schema, which is insufficient.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get'), the resource ('details for a brewery'), and the platform ('Untappd'). Among sibling tools, there is a separate search tool ('untappd_search_brewery'), so this tool's specific purpose of retrieving details for a known brewery is unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description is a single short sentence, but it lacks necessary detail; it is concise but under-specified.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 5 parameters and no output schema, the description fails to explain what data is returned or how the optional parameters affect results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage for 5 parameters; the description only mentions 'ASIN', providing no meaning for access_key, secret_key, partner_tag, or region.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get... product details') and the primary identifier ('by ASIN'), which distinguishes it from sibling tools like amazon_search.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus other Amazon tools (e.g., amazon_search, amazon_browse) or how to handle authentication parameters.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must fully convey behavior. It only states 'get', which implies a read operation, but does not disclose potential errors, authentication requirements, or data volume. The optional api_key parameter suggests authentication is needed but not clarified.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no extraneous words. However, it omits useful details that could be added without sacrificing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations, no output schema, and only two parameters, the description should cover return value, error handling, and authentication. It fails to do so, leaving the agent with insufficient context for reliable invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description should add meaning beyond parameter names. While it mentions 'by set number', it does not explain the api_key parameter's purpose or constraints. Both parameters are minimally described in the schema already.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves a specific LEGO set from Brickset by set number. It uses a specific verb (get) and resource (set) and distinguishes from sibling tools like brickset_search and lego_get_set.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as lego_get_set or brickset_search. The description lacks context about preferred use cases or prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description is minimal. It implies a read operation but does not disclose authentication requirements, rate limits, or any side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no redundancy, but could be expanded with more useful details without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple get-by-tag tool, the description covers the core purpose but lacks output schema info, error handling hints, or usage context. Adequate but minimal.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%; the description adds no additional meaning to parameters. 'clubTag' and 'api_key' are not explained (e.g., format of tag, role of api_key).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'Brawl Stars club', and distinguishes from sibling tools like 'bs_player' which gets a player.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives (e.g., if using 'bs_player' would be better for player info). No exclusions or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It states 'calculate', implying a read-only operation, but does not disclose any behavioral traits such as units of measurement, range checks, or precision of output.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but overly minimal. It lacks informative detail that would justify its brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (two numeric inputs, no output schema, no annotations), the description is minimally adequate but could be improved by clarifying units or the calculation formula.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage for its two parameters. The description adds no meaning beyond the tool's purpose, failing to explain that weight_kg should be in kilograms and height_cm in centimeters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states that the tool calculates Body Mass Index (BMI), using a specific verb-resource pair. It effectively distinguishes from sibling calculator tools like 'calc_mortgage' or 'calc_compound_interest' by naming the specific metric.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention any prerequisites, constraints, or context in which BMI calculation is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description fails to disclose important behaviors: read-only nature, rate limits, pagination, or what 'recent' means. The agent must infer behavior from the name alone.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise at one sentence, but trades completeness for brevity. While efficient, it omits critical details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema, no annotations, and zero schema coverage, the description is incomplete. It does not specify return format, error handling, or limitations, making it inadequate for proper agent usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%, and the description does not explain the purpose of year and month parameters. The agent is left to guess that they filter by time period, risking incorrect usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'Get recent games for a Chess.com player', specifying verb (Get), resource (recent games), and target (Chess.com player). This distinguishes it from sibling tools like chess_player, chess_player_stats, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives. No mention of filtering by year/month, prerequisites, or scenarios where another tool is more appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. 'Get details' implies a read-only operation, but it does not disclose what happens if the pipeline is not found (e.g., error handling), rate limits, authentication requirements beyond the API key, or any side effects. The behavioral disclosure is minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that is concise and front-loaded with the key action and resource. It avoids fluff, but could be slightly more informative without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given two parameters, no output schema, and no annotations, the description is minimal. It does not explain what 'details' are returned (e.g., pipeline status, branch, commit info). It is adequate for a simple get-by-ID operation but lacks completeness in outlining the response or error scenarios.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema covers both parameters (api_key, pipeline_id) with descriptions. Since schema coverage is 100%, the baseline is 3. The description does not add any additional meaning beyond what the schema provides, such as format constraints or examples.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets details for a single CircleCI pipeline by ID. It uses a specific verb ('Get details') and resource ('a single CircleCI pipeline'), making the purpose evident. However, it does not explicitly differentiate from sibling tools like circleci_list_pipelines, which lowers the score from a 5.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., circleci_list_pipelines for multiple pipelines, circleci_get_workflow for workflows). It does not mention prerequisites, such as needing a valid pipeline ID or API key, though these are implied by the schema. No when-not-to-use or alternative suggestions are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description bears full responsibility. It only states the action, lacking details on side effects, auth requirements (though api_key suggests auth), rate limits, or response characteristics (e.g., pagination).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no redundancy. However, it could be slightly improved by front-loading the most critical information, and it lacks structure.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with one parameter and no output schema, the description provides the basic purpose but omits parameter documentation and behavioral traits. It is adequate but leaves clear gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage for the required api_key parameter, and the tool description adds no explanation. The agent receives no guidance on what the api_key is or how to obtain it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'List', the resource 'email sequences', and the context 'ConvertKit account'. It is specific and distinguishes from sibling tools like ck_list_forms and ck_list_subscribers.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavior. It implies a read-only operation ('List all tags') but does not state side effects, authentication requirements (beyond api_key in schema), rate limits, or pagination.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence that is direct and to the point, with no redundant information. Appropriate for a simple list tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description lacks details on return format (e.g., whether it returns IDs, names, or full objects), pagination behavior, or error handling. For a tool with no output schema, this is incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. The description adds no meaning to the parameter 'api_key' (e.g., its purpose, source, or format). It does not compensate for the lack of schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('List') and resource ('tags') with context ('in a ConvertKit account'), clearly distinguishing it from sibling tools like ck_list_forms and ck_list_sequences.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives, such as ck_list_subscribers or ck_search_tags. No exclusion criteria or prerequisites mentioned.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It only mentions 'Get by tag' but fails to disclose authentication requirements (api_key parameter), rate limits, error handling, or other behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very short (one sentence) and front-loaded with the key action. However, it omits necessary details, making it incomplete rather than efficiently concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple, but with no output schema and missing parameter insights, the description is incomplete. It tells what the tool does but not how to use it correctly or what to expect.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description should compensate. It vaguely indicates clanTag is the identifier but doesn't specify format (e.g., '#' prefix) or explain the optional api_key parameter at all.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'Clash of Clans clan', and the unique identifier 'by tag'. Among sibling tools like coc_clan_members and coc_player, this tool's purpose is distinct.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool, prerequisites (e.g., API key), or alternatives like coc_clan_members. It lacks any context about usage scenarios.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise, only one sentence. While efficient, it could benefit from additional structure to convey more information without increasing length significantly.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of an output schema and annotations, the description should offer more context about return values, required scopes, or possible outcomes. It is insufficient for complete understanding.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is high (86%), so parameters are already well-documented in the schema. The description adds no extra meaning to the parameters beyond what is in the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Create a new task in Asana' clearly states the action and resource. It is specific enough for a create operation, but does not differentiate from sibling tools like 'update_asana_task' or 'get_asana_task'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise at one sentence, but it could be expanded with additional relevant details without becoming verbose. It is appropriately front-loaded but too brief.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and three parameters, the description is insufficient. It does not explain return values, date range, or the role of 'market', leaving significant gaps for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds minimal meaning. It does not explain the purpose of 'symbol', 'market', or 'api_key' beyond what the schema itself shows.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get daily crypto price history from Alpha Vantage', specifying the verb, resource, and data source. It distinguishes from sibling tools like crypto_price (current price) and crypto_coin_history (broader history).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like stock_daily or other crypto history tools. The description does not specify prerequisites, context, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description bears full responsibility for disclosing behavior. It does not mention any limitations (e.g., rate limits, data freshness, or that it is a read-only operation). The description is insufficient for an agent to understand potential side effects or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that conveys the core purpose without unnecessary words. It is appropriately sized but could benefit from slightly more detail without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity of the tool (2 parameters, no output schema), the description is somewhat complete. However, it lacks context on what the output looks like or how it interacts with siblings. For a minimal tool, it is adequate but not comprehensive.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema already describes both parameters with clear descriptions ('Comma-separated coin IDs', 'Comma-separated currency codes'). The tool description adds no additional meaning beyond the schema. With 100% schema coverage, baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states action ('Get') and resource ('cryptocurrency prices') with source ('CoinGecko'). However, it does not distinguish itself from sibling tools like crypto_coin or crypto_coin_history, which may have overlapping functionality.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is given on when to use this tool versus alternatives. For example, it does not mention that for historical prices, one should use crypto_coin_history. This leaves the agent without decision context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden for behavioral disclosure. It only says 'Run a C-Suite multi-perspective analysis', omitting important traits such as whether the tool is read-only, destructive, requires auth, or has side effects. No details on output format or potential delays.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, front-loaded with the core action. It avoids unnecessary words but may be too brief at the expense of completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters and no output schema, the description is incomplete. It does not explain what the analysis includes, how parameters interact, or what the output format is. More detail is needed for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 40%, with only 'perspectives' and 'depth' having descriptions. The description does not explain any parameters beyond what the schema provides, failing to compensate for the missing parameter descriptions. For example, 'scenario' is required but not described.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Run' and the resource 'C-Suite multi-perspective analysis' on 'business scenario', making the tool's purpose specific and distinct from sibling tools which do not mention C-suite or multi-perspective analysis.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. It merely states what the tool does without context for appropriate usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully disclose behavioral traits. It only says 'Create' but does not mention authentication, idempotency, rate limits, or effects like overwriting. This is a significant gap.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single 7-word sentence with no wasted words. However, it lacks structural elements like bullet points or additional context, slightly compromising completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 8 parameters (4 required) and no output schema, the description is incomplete. It does not explain the return value, how to construct query/message, or any restrictions, leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all 8 parameters. The description adds no additional meaning beyond the schema, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Create a new Datadog monitor (alert)', specifying the verb (create), resource (Datadog monitor), and action. It distinguishes from sibling tools like datadog_get_monitor and datadog_list_monitors.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, no prerequisites (e.g., API keys), and no exclusions. It only states the basic purpose.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description bears full responsibility for behavioral disclosure. It merely states 'List Datadog dashboards,' omitting details about whether the list is paginated, what fields are returned, or any side effects. The existence of a 'filter_shared' parameter is not highlighted, missing an opportunity to clarify behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at three words, leaving no room for waste. However, it could be slightly expanded to include a brief note on authentication or the optional filter parameter without sacrificing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool, the description is adequate but incomplete. It does not mention the optional 'filter_shared' parameter or the expected output format, which would be helpful given no output schema is provided. The tool's simplicity keeps the score at 3.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all three parameters (api_key, app_key, filter_shared). The description adds no additional insight beyond what the schema already provides, so the baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('List') and resource ('Datadog dashboards'). However, it does not differentiate from sibling tools like 'datadog_list_monitors' or 'datadog_list_events' beyond the resource name itself, which is already evident from the tool name.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as 'datadog_get_monitor' or 'datadog_query_metrics'. There is no mention of prerequisites, contexts, or cases where one would prefer another tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden, but it only states it lists languages. It does not disclose that it requires an auth_key (though schema does) or describe the response format, limitations, or whether it's a read-only operation. The description adds minimal behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with no wasted words. It is front-loaded and immediately conveys the tool's purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with no output schema and no annotations, the description is minimal. It does not explain what the returned language list looks like, whether there are pagination or rate limits, or how the 'type' parameter affects results. More context would be helpful.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with clear descriptions for both parameters (auth_key required, type with enum). The description does not add extra meaning beyond the schema, which already handles the parameter semantics adequately. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it lists all supported languages for translation, using the verb 'List' and specifying the resource. It distinguishes from the translation siblings (deepl_translate_text, etc.) but does not mention the optional 'type' parameter that filters by source or target languages.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, such as when preparing a translation request or checking available languages. The description simply states what it does without usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It only states 'Get', implying a read operation, but fails to disclose rate limits, authentication requirements (api_key), return format, or error handling.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at one sentence. While there is no waste, it sacrifices important details. For a simple tool, this is acceptable but not excellent.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity of the tool and absence of output schema or annotations, the description is incomplete. It does not mention what data the response contains, any prerequisites, or potential errors.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description should compensate. It does not explain release_id (e.g., numeric ID meaning) or api_key (how to obtain, required for authenticated requests). No value added beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'Discogs release', and specifies the identifier method 'by ID'. This distinguishes it from sibling tools like discogs_search_releases or discogs_get_artist.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives (e.g., search_releases). The context implies it is for fetching a single release by ID, but no when-not or exclusion criteria are provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. Description does not disclose any behavioral traits (e.g., read-only, rate limits, auth requirements beyond schema). Minimal transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with purpose. Efficient but lacks detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Missing explanation of 'full details', no output schema, no guidance on optional params like fieldgroups or marketplace. Incomplete for a 5-param tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is low (20%). Description only adds context for 'item_id' (example format). Other parameters (client_id, client_secret, fieldgroups, marketplace) are not elaborated.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'full details for an eBay item', and the key parameter 'item ID'. It distinguishes itself from sibling tools like ebay_search and ebay_get_categories.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like ebay_get_item_by_legacy_id or search. No mention of prerequisites or context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral context. It only states 'Get' (implying read-only) but omits details on rate limits, required permissions, or what happens if the item is not found. The required authentication parameters are not mentioned in behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single 12-word sentence, very concise. It front-loads the action. However, it may be too brief, lacking structure for clarity on optional parameters. Still, it avoids fluff and earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 6 parameters (3 required) and no output schema, the description is incomplete. It does not explain the return format, how to use variation parameters, or authentication details. Sibling tools with similar purposes are not differentiated in usage context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 17% (only legacy_item_id has a description). The description adds no new meaning to client_id, client_secret, legacy_variation_id, legacy_variation_sku, or marketplace. It merely restates that legacy_item_id is numeric, which is already in the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets an eBay item using a legacy numeric ID, distinguishing it from siblings like ebay_get_item (likely modern ID) and ebay_search (search-based). The verb 'Get' and resource 'eBay item' with specific ID type make purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like ebay_get_item or ebay_search. The description does not mention prerequisites (e.g., authentication via client_id/client_secret) or provide context for optional parameters like legacy_variation_id or marketplace.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description fails to disclose behavioral traits such as return format, data freshness, or whether scores are live or historical. This lack of transparency requires the agent to assume basic behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise—just one sentence. It is front-loaded and waste-free, though it lacks some helpful details that would improve clarity without sacrificing brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple nature of the tool (one optional parameter, no output schema), the description is incomplete. It does not specify whether scores are live, historical, or upcoming, which is essential context for proper usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with one parameter having a description ('e.g. eng.1, usa.1'). The description does not add extra meaning beyond the schema's example, so it meets the baseline but provides no added value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get soccer scores from ESPN.' clearly identifies the tool's purpose with a specific verb and resource. It effectively distinguishes itself from sibling tools like espn_mlb_scores and espn_nba_scores by specifying 'soccer'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of appropriate contexts, exclusions, or related tools, leaving the agent to infer from the name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    There are no annotations, so the description must disclose behavior. It only says 'Get active listings' without explaining authentication needs (api_key), pagination limits, sorting behavior, or what happens if the shop has zero active listings. The description is insufficient for a tool with no annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no fluff, but it is overly terse. Conciseness is good, but structure could be improved by adding a brief note on common parameters or behavior without sacrificing brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 6 parameters, no output schema, and no annotations, the description lacks completeness. It does not cover pagination (limit/offset), sorting (sort_on/order), or return expectations. Compared to more complete sibling descriptions, this one is sparse.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 6 parameters with 0% schema description coverage (no descriptions in the schema). The tool description does not mention any parameters or provide context for them (e.g., defaults for limit/offset, allowed sort_on values). This forces the agent to infer meaning from parameter names alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'active listings', and the context 'for an Etsy shop'. It distinguishes from sibling tools like etsy_get_listing (single listing) and etsy_search_listings (cross-shop search), making the purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidance is provided. The description does not indicate when to use this tool versus alternatives (e.g., etsy_search_listings), nor does it mention prerequisites like requiring a valid shop_id or how pagination works.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must carry behavioral disclosure. It only states conversion, omitting details like rate source, authentication needs, error handling, or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no redundancy. Could be more structured but is efficiently concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema provided; description does not mention return format. Adequate for simple tool but incomplete for richer context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. Description adds no meaning beyond schema; parameter descriptions are already clear in the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool converts currency amounts, using a specific verb and resource. However, it does not differentiate from sibling tools like forex_convert or exchangerate_historical, which also perform conversions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives. Does not specify prerequisites, context, or when the optional api_key is needed.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behaviors. It only states the basic purpose without detailing what happens on failure, distance calculation, data source, or pagination. Very little behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it lacks structure and important details. It is under-specified rather than efficiently concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema and 4 parameters, the description leaves many gaps: no info on return format, default radius, error handling, or limits. The tool is simple but still needs more context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 25% (only radius gets a description). The description adds no additional meaning for latitude, longitude, or limit. It merely repeats the radius description already in the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool finds nearest public toilets to a location with a geographic constraint (Australia). It uses a specific verb and resource, and distinguishes from siblings like get_toilet_details.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives. For example, get_toilet_details exists for specific toilet info, but no mention of when to use which. No when-not-to-use advice.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behavioral traits like destructiveness, idempotency, or permissions. It only says 'Create a new machine', omitting that this is a write operation, likely requires authentication, and may have side effects (e.g., starting a machine). Insufficient for a mutation tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise (one sentence), which is positive for brevity, but it omits crucial details needed for correct usage. It could benefit from a structured format listing key capabilities or behavior, while still being succinct.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 5 parameters, 2 required, and no output schema, the description is too minimal. It does not explain return values, error conditions, prerequisites, or how parameters like api_key should be obtained. The context from sibling tools suggests this is part of a larger system, but the description fails to tie it together.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning beyond the input schema. Schema coverage is 60%, but the description does not explain the undocumented parameters (api_key, app_name, env). For required parameters, only image and machine_name have schema descriptions; app_name lacks both schema and description context.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Create'), the resource ('machine'), and the context ('in a Fly.io app'). It effectively distinguishes from sibling tools like fly_list_machines (list) or fly_get_app (get), which have different verbs and resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, prerequisites (e.g., app must exist), or scenarios to avoid. The single sentence offers no contextual or comparative advice.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It only states 'List all machines', implying a read operation, but fails to disclose any behavioral traits such as pagination, rate limits, or whether it returns deleted machines by default. The description is too minimal to be sufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence of 6 words with no redundant information. However, it sacrifices necessary detail for brevity, making it less informative than it could be.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 3 parameters, no output schema, and no annotations, the description is insufficient. It does not explain how to use the parameters together, what the output format is, or any constraints. An agent would lack critical context to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description should add meaning to parameters, but it only mentions 'machines in a Fly.io app'. It does not explain the role of 'api_key', 'app_name', or 'include_deleted' (e.g., what 'include_deleted' does). The description fails to compensate for the lack of parameter documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List all machines in a Fly.io app' clearly states the tool's purpose with a specific verb-list and resource-machines within a Fly.io app context. It distinguishes itself from sibling tools like fly_create_machine, fly_get_app, fly_list_apps, and fly_list_volumes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as fly_list_apps or fly_list_volumes. It lacks any mention of prerequisites, required permissions, or scenarios where this tool is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden. It only states a read operation without detailing authentication needs, rate limits, or any side effects. Minimal behavioral disclosure.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    One sentence with no fluff, but it could be expanded to include more helpful context without sacrificing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and simple parameters, the description is inadequate. It omits output format, pagination, error handling, and prerequisites, leaving gaps for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning the schema has no parameter descriptions. The description does not add meaning for the two parameters (api_key, app_name) beyond what is obvious from the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists all volumes attached to a Fly.io app, with a specific verb ('List') and resource ('volumes'), and distinguishes from sibling tools like fly_list_apps and fly_list_machines.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives, no prerequisites, and no exclusions. The description lacks context for appropriate usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description bears full responsibility for behavioral disclosure. It only states the action without mentioning any traits such as authentication needs (api_key is optional but not explained), error states, rate limits, or side effects. The absence of such detail leaves the agent underinformed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is brief and front-loaded, but it is too minimal. It could be more informative without losing conciseness, such as noting the source of the artist data or typical response content. It is adequately concise but under-specified.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given there is no output schema, the description should at least hint at what is returned (e.g., artist details). It does not. Additionally, it lacks context on error handling, required authentication, or how the ID is used. The tool has only two parameters, but the description still feels incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Input schema has 0% description coverage, and the tool description adds no clarification beyond the field names. 'Get ... by ID' implies the 'id' parameter is used, but there is no explanation of 'api_key' or any constraints. The description fails to compensate for the lack of schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description specifies a clear action ('Get') and resource ('Genius artist by ID'). It effectively distinguishes from sibling tools like 'genius_search', 'genius_get_song', and 'genius_artist_songs' by indicating a direct lookup by identifier.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description offers no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, contexts, or situations where other tools might be more appropriate, leaving the agent to infer usage solely from the name and siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description must cover behavioral traits. It only states 'Get full details' without describing what 'full details' entails, potential rate limits, authentication expectations, or response size. Minimal transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence that front-loads the purpose; no wasted words. However, it lacks any structure (e.g., paragraphs, examples) that could aid readability.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple get operation with one required parameter, the description is marginally adequate but incomplete. No output schema, no details on response format, and no differentiation from similar tools. The context of many siblings demands more explicit guidance.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 50% (task_gid described as 'Task GID', api_key not described). Description adds no extra meaning beyond the schema. The phrase 'full details' does not clarify parameter usage or expected format for task_gid.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states 'Get full details of a single Asana task,' combining a clear verb ('get'), resource ('Asana task'), and specificity ('full details', 'single'). It distinguishes itself from sibling tools like list_asana_tasks (multiple tasks) and search_asana_tasks (search-based).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., needing a task_gid) or scenarios where list or search tools would be more appropriate. The description is purely declarative.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose all behavioral traits. It only states the tool 'gets details' but does not specify if it is read-only, if authentication is required (beyond the api_key parameter), rate limits, or what constitutes 'details'. Significant gaps remain.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, focused sentence with no unnecessary words. It front-loads the core action and intended inclusion. However, it could be slightly more structured (e.g., bullet points) for clarity, but overall it is concise and efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and annotations, the description should provide more context about the response format, authentication requirements, and possible errors. The minimal description leaves the agent underinformed for a complete interaction.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (board_id has a minimal 'Board ID' description; api_key has none). The description adds no parameter details beyond the schema, failing to explain the api_key's purpose or format. Baseline is 3 due to coverage, but description does not compensate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'Monday.com board', and specific included details 'columns and groups'. This distinguishes it from sibling tools like list_monday_boards (lists all boards) and create_monday_item (creates items), providing a precise purpose.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description offers no guidance on when to use this tool versus alternatives. It does not mention prerequisites, context of use, or when to avoid it. With many Monday.com sibling tools, this omission leaves the agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits like pagination, rate limits, or recency guarantees. The description is too sparse to inform the agent about side effects or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but under-specified. While it avoids verbosity, it lacks necessary detail for a complete definition.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite the tool's simplicity (one optional parameter, no output schema), the description omits critical context like default behavior, pagination details, and how it differs from related sibling tools.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% coverage for the parameter 'resultsPerPage' (no description, constraints, or defaults). The description does not explain its meaning or usage, failing to compensate for the schema gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'get', resource 'recently published CVEs', and source 'NVD'. It effectively distinguishes from sibling tools like 'get_cve_detail' and 'search_cve'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as 'get_cve_detail' or 'search_cve'. No explicit context or exclusions are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description only states the basic purpose. It does not disclose output format, authentication requirements (api_key parameter is optional but not explained), or any potential side effects or limitations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no unnecessary words. However, it could be structured to include more information without verbosity, such as noting required parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of output schema and annotations, the description is too brief to fully inform the agent. It does not describe the response structure (e.g., list of achievement objects) or any pagination, making it incomplete for a tool that returns a list of achievements.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 67% description coverage (steamid and appid have descriptions, api_key does not). The tool description does not add any extra meaning beyond the schema's brief descriptions; it does not explain how to obtain a Steam64 ID or App ID.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves achievements for a Steam user in a specific game, using a specific verb and resource. It differentiates from sibling tools like get_steam_player_summaries and get_steam_owned_games.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like get_steam_app_details or get_steam_owned_games. The description does not explain prerequisites such as requiring a valid Steam64 ID and App ID.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description bears the full burden of behavioral disclosure. It only states the basic action without mentioning authentication requirements, rate limits, error handling, or what happens when an edition ID is invalid.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of an output schema and annotations, the description should provide more context about return values, potential errors, and typical use cases. It fails to do so, leaving the agent with insufficient information to use the tool confidently.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage, and the description only hints at the 'edition_id' parameter via 'by ID.' It fails to explain the purpose of the optional 'api_key' parameter or specify the format/expected values for 'edition_id.' This leaves the agent with significant ambiguity about how to construct the call.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'Guardian edition by ID,' making the tool's specific purpose immediately clear. It differentiates from sibling tools like guardian_get_article and guardian_get_sections by specifying 'edition' as the target.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternative Guardian tools (e.g., search_articles or get_sections). No context is given about what an edition represents or prerequisites for retrieval.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description carries full responsibility. It does not mention any behavioral traits like authentication requirements, rate limits, or that the operation is read-only. The description is too minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. It is appropriately short and front-loaded with the verb and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema, no parameter details, and minimal description, the tool is incomplete. Important context such as return format, required authentication, and pagination (if any) is missing.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has one parameter (api_key) with no description, and the tool description does not mention or explain it. With 0% schema coverage, the description fails to add any meaning.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'all Guardian sections', which directly conveys the tool's purpose. It distinguishes itself from sibling tools like guardian_get_article, guardian_get_edition, etc., which operate on different entities.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, putting the full burden on the description. It does not disclose behavioral traits like authentication requirements (beyond the required api_key), rate limits, or whether the operation is read-only.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no wasted words. It conveys the core purpose efficiently.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with one parameter and no output schema, the description is minimal. It does not specify return values, pagination, or any other details that would help the agent understand the tool's output or limitations.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% for the single parameter api_key. The description adds no additional meaning beyond what the schema already provides ('HeyGen API key'), so baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists all available voices for HeyGen avatar videos. It is specific with verb 'list' and resource 'voices', but does not explicitly distinguish from sibling tools like heygen_list_avatars, though the tool name provides differentiation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. It does not mention prerequisites, such as having a valid API key, or scenarios where this tool is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description simply says 'Verify an email address' without explaining what verification entails (e.g., syntax check, domain check, SMTP verification), potential failure modes, or reliance on the api_key parameter. No annotations are provided, so the description carries the full burden but does not fulfill it.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise. However, it lacks structure and does not front-load key information beyond the basic purpose. It could be improved while remaining terse.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of an output schema, annotations, and detailed parameter descriptions, the description is incomplete. It does not explain the output format, potential errors, rate limits, or authentication specifics, which are critical for a verification tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has two parameters (email, api_key) with 0% description coverage. The description does not explain the api_key parameter or how it is used. It adds no meaning beyond the basic action, leaving the agent to infer the purpose of the parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('verify'), the resource ('an email address'), and the service ('with Hunter.io'). It distinguishes itself from sibling tools like hunter_domain_info and hunter_find_email by focusing on verification of a single email.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidelines are provided on when to use this tool versus alternatives such as hunter_domain_info or hunter_find_email. There is no mention of context, prerequisites, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavior. It fails to mention authentication requirements (client_id, client_secret) or what 'full details' entails, leaving the agent without critical context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. It is front-loaded effectively, though it could be slightly more informative without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and 3 parameters, the description is insufficient. It does not clarify the output format, authentication needs, or how to obtain a game ID from sibling tools.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 33%; only game_id has a description. The description adds no parameter-level information, missing opportunities to explain client_id and client_secret as optional auth parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves full details of a game by ID. It distinguishes from siblings like igdb_search_games and igdb_get_company.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., igdb_search_games to obtain ID). It does not mention any prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full responsibility for behavioral disclosure. It only states the basic function, omitting critical details such as whether the operation is read-only, error handling (e.g., invalid IPs), rate limits, or response format. This leaves the agent uncertain about side effects and constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, which is efficient but underspecified. It sacrifices completeness for brevity. For a simple batch operation, it is adequate but could benefit from slightly more detail without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description lacks completeness given the absence of output schema and annotations. It does not explain the geolocation data returned, data source, or any constraints. The schema also misses a description for 'api_key'. The overall information is insufficient for reliable tool invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no parameter-specific meaning beyond the schema. The 'ips' parameter is described in schema as 'Array of IP address strings', but the description does not clarify IP format, batch size limits, or how the optional 'api_key' should be used. Schema description coverage is 50%, missing description for 'api_key'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Batch IP address geolocation lookup' clearly states the tool's function with a specific verb (batch lookup) and resource (IP addresses). It distinguishes from the sibling tool 'ip_lookup' which likely handles single IP lookups.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidelines are provided. The description does not indicate when to use this batch tool versus alternatives (e.g., single IP lookup), nor any prerequisites or limitations. The agent must infer usage from the tool name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for behavioral transparency. It mentions that the tool checks against an 'issue-spotter guardrail' and returns a 'legally reviewed disclaimer banner', but does not disclose any side effects, required permissions, or safety implications (e.g., whether it modifies data). The verb 'lint' suggests non-destructive analysis, but this is not stated explicitly.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that front-loads the main action ('lint') and goal. It is concise with no wasted words. However, it could be slightly more structured by separating the guardrail check from the return value for clarity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with two simple parameters and no output schema, the description provides enough context for basic use. It explains the input (verdict text) and output (disclaimer banner), but does not elaborate on what the guardrail does or the format of the banner. It is minimally complete but leaves room for ambiguity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema covers both parameters with descriptions, achieving 100% coverage. The description adds context like 'LegalPass-style' and 'legally reviewed', but does not significantly enhance understanding beyond what the schema already provides. As per guidelines, baseline is 3 when schema coverage is high.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: linting LegalPass-style verdict text against a guardrail and returning a disclaimer banner. It uses specific verbs ('lint', 'return') and identifies the resource ('verdict text', 'disclaimer banner'). While it distinguishes from siblings by mentioning 'LegalPass-style', it could be more explicit about how it differs from 'legalpass_run'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description lacks guidance on when to use this tool versus alternatives like 'legalpass_run'. It does not provide any context about prerequisites, when not to use it, or which scenarios are appropriate. Implied usage is only for verdict text, but no explicit comparison to siblings is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided. The description mentions the data source (Rebrickable) but does not disclose any behavioral traits such as rate limits, authentication requirements, or how parameters interact. The brief description adds minimal context beyond the name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence that is front-loaded with the action and resource. No extraneous words, making it highly efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 6 parameters and no output schema or annotations, the description is severely incomplete. It lacks details on required inputs, usage restrictions, and expected output.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage and 6 parameters, the description only explains 'name' and 'theme' (via 'by name/theme'). It does not clarify min_year, max_year, page_size, or api_key, leaving significant gaps for the agent.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search' and the resource 'LEGO sets' with criteria 'by name/theme' and source 'Rebrickable'. It effectively distinguishes this tool from siblings like lego_get_set or lego_set_parts.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like lego_get_set or lego_themes. It only implies search functionality without exclusions or context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for behavioral disclosure but only states the basic action. It omits any details about data returned, authentication requirements, or rate limits, leaving the agent with minimal behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it is under-specified. It achieves brevity at the cost of depth, earning a middle score.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one required parameter, no output schema), the description is minimally adequate. However, the context of many sibling tools suggests more detail would improve completeness. The description could hint at what a user profile contains or how to use the result.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning beyond the schema for the single 'username' parameter. It does not clarify case sensitivity, allowed characters, or whether the username is case-sensitive, leaving the agent without guidance on correct input.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get a Lichess user profile' clearly states the verb 'Get' and the resource 'Lichess user profile', accurately reflecting the tool's function and distinguishing it from sibling tools like lichess_user_games or lichess_top_players.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as lichess_user_games or lichess_top_players. The description lacks context about prerequisites, typical use cases, or any exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided. The description says 'Interact with the Linear GraphQL API' implying API calls, but it does not disclose behavioral traits such as rate limits, idempotency, or side effects beyond 'create' actions. The burden falls on the description, which is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence that lists actions without redundancy. It is front-loaded with the main purpose. Slightly longer than necessary but still concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a compound tool with 11 parameters and no output schema or annotations, the description only provides a high-level summary. It lacks details on parameter interactions, return values, and error handling. Adequate but leaves gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers 100% of parameters with descriptions. The description adds no extra meaning beyond summarizing actions; it does not clarify parameter relationships or constraints. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool interacts with the Linear GraphQL API and lists five main actions (list/search issues, create issues, get project, list teams). This provides a specific verb-resource mapping. However, it could be more precise about the scope (e.g., 'list and search issues' is broad) and doesn't differentiate from non-existent Linear siblings.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description gives no guidance on when to use this tool vs. alternatives. Among many sibling tools (github_action, notion_action, etc.), there is no context for choosing Linear_action. It also does not mention prerequisites or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. Description fails to disclose behavioral traits such as rate limits, message length limits, or delivery confirmation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Very concise single sentence, front-loaded. Loses a point due to lack of structure (e.g., bullet points) but still clear.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, so description should explain return value (e.g., message ID). Does not provide context on obtaining channel_access_token or constraints on message. Incomplete for a 3-param required tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Only one of three parameters ('to') has a description in the schema. Description adds no extra meaning beyond parameter names. Schema coverage is 33% (<50%), and description does not compensate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clear verb 'Send', specific resource 'text message', and targets 'user, group, or room'. Distinguishes from sibling tools like line_broadcast and line_reply_message.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like line_reply_message or line_broadcast. Lacks context for choosing this tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully disclose behavior. It only says 'List scheduled events', omitting details like pagination, rate limits, authentication requirements (api_key parameter), or scope of events (future vs past).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (8 words) but fails to include necessary details for effective tool use. Conciseness should not come at the expense of completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 7 parameters, no output schema, and no annotations, the description is inadequate. Missing information on output format, pagination, default values, and error states makes it incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning beyond the input schema. With 71% schema coverage, the description should elaborate on parameters like count or api_key, but it only provides a generic phrase.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List' and resource 'scheduled events' with the scope 'for the authenticated Calendly user'. It distinguishes from sibling tools like 'get_calendly_event' (single event) and 'list_calendly_event_types'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like 'get_calendly_event' or 'list_calendly_invitees'. The description does not provide context for selection criteria.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description carries full burden for behavioral disclosure. It does not mention anything about authentication, rate limits, pagination, or the nature of the data returned. The description adds no behavioral context beyond the basic listing operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but lacks structure. It is appropriate for a simple list operation but does not use front-loading or clear formatting to aid scanning.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters, no output schema, and no annotations, the description is very incomplete. It does not explain what an invitee is, what fields are returned, any prerequisites like having an event UUID, or how to interpret the response. A more complete description is needed for effective tool selection and use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (2 of 4 parameters have descriptions), but the tool description adds no additional meaning to the parameters. It does not explain what 'status' values are allowed (though schema says 'active or canceled') or what 'count' and 'api_key' are for. The description fails to compensate for the undocumented parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (list) and resource (invitees for a Calendly scheduled event), which distinguishes it from siblings like get_calendly_event, list_calendly_events, and list_calendly_event_types. The verb+resource combination is specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description does not mention requiring the event UUID (although it's in the schema), nor does it differentiate from listing all events or getting an event. There is no indication of prerequisites or appropriate context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description states comments are returned in chronological order, but does not disclose pagination behavior (though a limit parameter exists), rate limits, or any other behavioral traits. With no annotations, more detail would be expected.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that front-loads the purpose. It is concise, but could add important details without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema, the description does not describe the structure of returned comments. It also fails to compensate for the 0% schema description coverage by explaining parameters. The context is incomplete for effective tool use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must add meaning. It only mentions that agent_id is required, without explaining the purpose or format of any parameters. The target_kind, target_id, and limit parameters are not described, leaving ambiguity.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it returns comments on a specific Boardroom todo or idea, in chronological order. It names the resource and action, but does not explicitly differentiate from sibling tools like 'comment_on' for creating comments.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description only mentions that agent_id is required, providing no guidance on when to use this tool versus alternatives, when not to use it, or any prerequisites beyond the required parameter.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description must disclose behavior. It does not mention authentication, rate limits, pagination, or whether it returns all items or only up to the limit. The limit parameter is in the schema but not elaborated in the description.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no wasted words. It is appropriately sized for a simple listing operation.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read tool with 3 parameters and no output schema, the description is minimally adequate. It states the core function but lacks details like output format, error handling, or behavior when limit is exceeded.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 67%, which is moderate. The description adds no extra meaning to the parameters beyond what the schema already provides (e.g., board_id and limit are described in the schema but not expanded upon in the description).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (list) and resource (items in a Monday.com board). It is specific enough to distinguish from sibling tools like list_monday_boards, but does not differentiate from search_monday_items, which also retrieves items.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like search_monday_items. There is no context on prerequisites, board access requirements, or typical use cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavior. It fails to mention pagination (page_size, bookmark), authentication requirements (access_token), or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise single sentence with no fluff. Could be slightly expanded for clarity, but efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Missing output schema and behavioral details. Does not explain return values, pagination, or authentication requirements.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 25% (only board_id has a description). The tool description adds nothing beyond 'Board ID' for board_id and nothing for other params.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List pins on a Pinterest board' clearly states the verb and resource, and distinguishes from siblings like 'create_pinterest_pin' and 'list_pinterest_boards'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like 'search_pinterest_pins' or its limitations (e.g., requires board_id).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so the description should disclose behaviors. It fails to mention pagination, authentication requirements, rate limits, or the return format. The brief description leaves the agent uninformed about query behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single 8-word sentence, extremely concise and front-loaded. However, it sacrifices necessary details for brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and low schema coverage, the description is insufficient. It does not explain what a 'store' is, the response structure, or handle edge cases. The tool is simple but the description is too sparse.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Only the api_key parameter is described in the schema (33% coverage). The description adds no meaning to the parameters, especially page and per_page which are left unexplained.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (list), resource (stores), and scope (on your account), distinguishing it from other ls_list_* tools like ls_list_customers or ls_list_products.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. It does not mention prerequisites, context, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description does not disclose any behavioral traits beyond the filtering action. With no annotations, the agent gets no information about safety, authentication requirements, or response format, making transparency very low.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single efficient sentence that is appropriately sized for a simple tool. It is front-loaded with verb and noun, though it could be slightly expanded without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity, lack of schema description, no annotations, and no output schema, the description is far from complete. It does not explain the output format, matching behavior, or any limitations, leaving significant gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The sole parameter 'ingredient' has no schema description and the tool description merely says 'by main ingredient', adding no examples, constraints, or format details. The agent must infer valid inputs from the name alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Filter meals by main ingredient' clearly states the specific verb and resource, and differentiates from sibling tools like meal_filter_by_area and meal_filter_by_category which filter by different criteria.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as meal_search or other filter tools. The description lacks any context about preferred use cases or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description only states 'search by name'. Does not disclose whether search is fuzzy, case-sensitive, paginated, or any other behavioral traits beyond the basic operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, highly concise and front-loaded with essential information. However, it could be slightly expanded to include behavioral context without losing brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple search tool with one parameter and no output schema, the description is minimal but does not cover expected behavior like result ordering or what fields are searched beyond name.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage for the single 'query' parameter. Description adds 'by name' implying query is a meal/recipe name, but lacks details on format, partial matching, or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'search', resource 'meals/recipes', and the search attribute 'by name'. This differentiates it from sibling tools like meal_filter_by_ingredient or meal_random.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as meal_filter_by_area or meal_categories. Agent must infer usage from semantics alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It does not mention behavioral traits such as idempotency, token consumption, or rate limits. The phrase 'Create vector embeddings' implies a write-like operation but lacks clarity on side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no verbosity. It is concise but could benefit from mentioning output format. Front-loads the core purpose effectively.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 3 parameters and no output schema, the description should explain the return value (embedding vector). It does not. Additionally, no guidance on when to use this over sibling embedding tools from other providers.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 67% (2 of 3 params have descriptions). The description adds no extra meaning beyond the schema. Baseline 3 is appropriate as schema does the heavy lifting.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Create vector embeddings for text using Mistral's embedding model,' which is a specific verb+resource. It distinguishes from sibling tools like mistral_chat_completion but does not differentiate from other embedding tools (e.g., cohere_embed, openai_create_embedding).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives (e.g., cohere_embed, openai_create_embedding). The description lacks context about prerequisites or scenarios for embedding creation.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must convey behavioral traits. It only states the action without disclosing pagination, data volume limits, rate limits, authentication details, or any side effects. This is insufficient for an export tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence with no wasted words. However, its brevity sacrifices completeness, preventing a higher score.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 8 parameters and no output schema, the description is too sparse. It fails to explain return format, pagination behavior, or any operational constraints, making it incomplete for an agent to use confidently.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description does not add extra meaning beyond what the schema already provides for each parameter. No additional context about parameter usage or constraints is given.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description specifies 'Export raw Mixpanel event data for a date range', clearly stating the verb, resource, and scope. It distinguishes from siblings like mixpanel_get_events by emphasizing 'raw' data, but does not explicitly contrast with them.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It lacks information on prerequisites, context, or exclusions, leaving the agent without enough decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden of behavioral disclosure. It only states the tool gets data, implying a read operation, but does not disclose any behavioral traits such as rate limits, data volume, required permissions, or whether the response includes step-by-step conversion counts or aggregated metrics.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence with no unnecessary words. It is front-loaded with the action and resource, which is optimal for quick comprehension.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 7 parameters, no output schema, and no annotations, the description is insufficient. It neither explains what funnel conversion data comprises (e.g., steps, conversion rates) nor clarifies the time range implications (from_date, to_date, unit). The agent must infer critical details from parameter names alone.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema already documents all 7 parameters with descriptions. The tool description adds no additional meaning beyond the schema, such as how to construct effective queries or parameter interactions. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get funnel conversion data from Mixpanel' clearly states the verb (get), resource (funnel conversion data), and source (Mixpanel). The resource name distinguishes it from sibling tools like mixpanel_get_events or mixpanel_get_retention, though it does not explicitly differentiate by scope (e.g., specific funnel vs. all funnels).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidelines are provided. There is no indication of when to use this tool over alternatives (e.g., mixpanel_get_events), no prerequisites (e.g., need a funnel ID from Mixpanel UI), and no exclusions or context about data availability.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden for behavioral disclosure. It merely restates the action ('track a custom event') without explaining side effects (e.g., immediate ingestion, asynchronous processing), required permissions beyond the schema, or rate limits. This is only slightly better than a tautology.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 6 words, which is very concise. It front-loads the core purpose. While it could include more detail, for conciseness it is efficient and not verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 7 parameters (5 required) and no output schema, the description is too minimal. It does not explain expected outcomes, error scenarios, or any constraints. The rich schema partially compensates, but the description fails to provide the operational context needed for complex tools.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema already documents all parameters. The description adds no extra meaning about how parameters interact, default values, or usage patterns. It meets the baseline of 3 but does not enhance understanding beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Track a custom event in Mixpanel', which clearly indicates the tool's action (tracking) and resource (custom event in Mixpanel). It distinguishes from sibling Mixpanel tools that query data (e.g., mixpanel_get_events) by using the verb 'track', but does not explicitly differentiate.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. Given sibling tools like mixpanel_get_events, mixpanel_get_funnels, etc., explicit usage context would be beneficial. The one-sentence description lacks any when-to-use, when-not-to-use, or prerequisite information.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavioral traits. It only states 'create a new branch' but omits critical details like whether the operation is destructive, requires authentication, or what happens if the branch name already exists. The description does not convey safety or mutation characteristics.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it is underspecified. While there is no extraneous information, the brevity comes at the cost of completeness, making it minimally acceptable.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of annotations and output schema, the description should provide more context about the creation process, such as default behavior, response format, or side effects. It is insufficient for an agent to fully understand the tool's behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 33%, with only branch_name having a description. The description does not add any extra meaning for the parameters beyond what is in the schema. It fails to clarify the purpose of api_key or project_id or how they relate to the action.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (create) and resource (branch) within the context of a Neon project. It effectively distinguishes from sibling tools like neon_list_branches and neon_execute_sql, which have different purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, nor are there any prerequisites or context for invocation mentioned. The description lacks any usage context, such as requiring an existing project or providing the api_key.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the full burden. It only states 'Get details' without specifying what details are returned, if any side effects exist, or if authentication is required. The api_key parameter hints at auth, but the description does not clarify.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, efficient, but could benefit from minimally structured additional context like output format or parameter roles.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 2 parameters, no output schema, and no annotations, the description is too minimal. It does not explain what 'details' means, the format of project_id, or behavior of api_key. Incomplete for an agent to use effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 50% (only project_id has a description). The description does not add any meaning beyond the schema; api_key is left undocumented. Baseline for 50% coverage is 3, but description adds zero value, so score is 2.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Get details), resource (Neon project), and scope (specific). It effectively distinguishes from sibling tools like neon_list_projects which list all projects.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives, no prerequisites or context provided. The agent must infer from the name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full responsibility. It only states the basic function, omitting details like authentication (api_key is optional but not explained), rate limits, or read-only nature.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise (one sentence), but it sacrifices useful details. While no words are wasted, it is under-specified for a practical tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and minimal behavioral info, the description lacks completeness. It doesn't explain return format, error handling, or any prerequisites beyond an IMDb ID.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers 50% of parameters (only 'i' has a description). The tool description adds no extra meaning beyond the schema, and the 'api_key' parameter remains undocumented.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it retrieves an OMDB movie/show by IMDb ID, using a specific verb and resource, and differentiates from siblings like omdb_by_title and omdb_search.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. It doesn't mention that this is for exact ID lookup, while other siblings handle title search or broader queries.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but adds no behavioral context. It omits authentication requirements (api_key), rate limits, or response format, leaving the agent with only schema clues.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The single sentence is concise and front-loaded, but it sacrifices necessary details. Slightly better than a tautology but still under-specified.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 4 parameters, no output schema, and no annotations, the description is too minimal. It does not explain what OMDB is, how the search works, what results look like, or how to handle authentication.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is low (25%), and the description does not compensate. It fails to explain 'type' (e.g., movie, series) or 'y' (year), and does not clarify the role of 'api_key'. The description adds no value beyond the schema's minimal description of 's'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Search movies/TV shows on OMDB', specifying the verb (search), resource (movies/TV shows), and data source (OMDB). This distinguishes it from sibling tools omdb_by_id and omdb_by_title, which are for specific lookups.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. It does not mention that omdb_by_id or omdb_by_title should be used for exact matches, nor does it indicate any prerequisites or limitations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It only states the high-level action ('run a chat completion') without disclosing behavioral traits like cost, rate limits, safety implications, or output format. Critical details for a generative AI tool are missing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that front-loads the verb and object. It is efficient but could incorporate more contextual information without expanding length unduly.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 12 parameters, no output schema, and multiple sibling tools performing similar tasks, the description is too sparse. It does not explain return values, error handling, special behaviors (e.g., streaming), or how to structure messages. The agent lacks sufficient context for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50%, meaning half of the 12 parameters lack descriptions in the schema. The description adds no parameter-level information beyond naming the model family. It fails to compensate for the missing schema descriptions, especially for parameters like max_tokens, temperature, and seed.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool runs a chat completion with OpenAI models (GPT-4o, GPT-4, etc.). It identifies the specific provider and task, distinguishing it from siblings by model family, but does not explicitly contrast with other chat completion tools like Anthropic or Groq.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when an OpenAI chat completion is needed, but provides no explicit guidance on when to use this tool versus alternatives, no prerequisites, and no exclusion criteria. The only hint is the focus on OpenAI models.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It only states the action; no details on auth needs, cost implications, file handling, or whether it's a read/write operation beyond inferring transcription.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Description is a single sentence, no wasted words. However, it is under-specified for the tool's complexity, so it's not ideally concise—it lacks necessary details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 8 parameters, no output schema, and no annotations, the description is severely lacking. It does not cover model options, response formats, or any practical usage context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 50% (4 of 8 parameters have descriptions). The description adds no parameter information; it just repeats the tool's purpose. It does not compensate for the undocumented parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'transcribe' and resource 'audio to text', and specifies the underlying model 'OpenAI Whisper'. It distinguishes from sibling OpenAI tools like chat, embeddings, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives. No prerequisites, when-not-to-use, or alternative transcription tools mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description fails to disclose any behavioral traits. It does not mention authentication requirements (beyond having api_key as a required parameter), rate limits, costs, or any side effects. The minimal statement 'using DALL-E' hints at the model but provides insufficient transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that immediately conveys the tool's purpose. It is front-loaded and efficient, with no unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (8 parameters, no output schema) and the abundance of sibling image generation tools, the description is far from complete. It lacks information about supported DALL-E versions, output format, error handling, and parameter interactions. The absence of any return value description is a significant gap.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds minimal value beyond the input schema. It references 'text prompt' which maps to the prompt parameter, but the schema already covers most parameters with descriptions (75% coverage). The description does not explain api_key or provide additional context for other parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (generate), the resource (images), and the method (from a text prompt using DALL-E). It effectively distinguishes this tool from other image generation tools in the sibling list, such as those from Stability AI or Higgsfield.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like stability_text_to_image or higgsfield_generate_image. It lacks any contextual cues for selecting DALL-E over other models.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description fully bears the burden of disclosing behavioral traits. It only states 'Create' without explaining that this operation is non-idempotent, may trigger alerts, requires authentication, or produces a new incident record. Key behavioral details (e.g., rate limits, effect on existing incidents) are omitted.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that immediately conveys the core function. It is front-loaded and contains no superfluous words. However, it may be too brief given the tool's complexity, missing structure like a summary of key parameters or behavior.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 6 parameters (3 required), no output schema, and no annotations, the description is insufficiently complete. It fails to mention that the tool returns the created incident details, that it triggers notifications, or that certain parameters (e.g., 'from') may be required based on account settings. The agent lacks context to fully understand the tool's impact.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema provides descriptions for all 6 parameters (100% coverage), so the baseline is 3. The description adds no additional parameter-level context beyond what the schema already offers (e.g., that 'urgency' defaults or 'from' is conditionally required). It neither improves nor degrades clarity.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool creates a new PagerDuty incident on a service. It uses a specific verb ('Create') and resource ('PagerDuty incident'), which differentiates it from sibling tools like pagerduty_acknowledge_incident, pagerduty_resolve_incident, etc. However, it does not explicitly mention the required service context beyond what the schema indicates.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool vs. alternatives (e.g., acknowledge, resolve). It does not mention prerequisites such as having a valid API key or service ID, nor does it indicate scenarios where creating an incident is appropriate (e.g., alerting on-call teams).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description must fully convey behavioral traits. It only lists actions (list, create, send) without disclosing side effects, authentication requirements, idempotency, or error behavior. Critical information about write operations is omitted.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, which is concise but lacks structured information. It does not front-load the most important details (e.g., that action determines parameter requirements). It is functional but could be more efficient and informative.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 8 parameters, no output schema, and complex actions (create/send), the description is incomplete. It fails to mention parameter dependencies, pagination, or sandbox mode. The tool's capabilities are underdescribed for an AI agent to use correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 38%, yet the description adds no meaning beyond the schema. It does not explain the 'invoice' object structure, the relationship between 'action' and required parameters ('invoice_id' for send, 'invoice' for create), or pagination ('page', 'page_size') and sandbox usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List, create, or send PayPal invoices' clearly states the verb and resource, listing three distinct actions on invoices. It distinguishes from sibling tools like 'paypal_orders' which handle orders.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidelines are provided on when to use this tool versus alternatives, such as 'paypal_orders' or other payment tools. No prerequisites, context, or exclusions are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description bears full burden. It only indicates a read operation but lacks details on pagination, rate limits, or any side effects. Minimal behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with 12 words, concise but lacks structure and may be too terse for a tool with many parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (9 parameters, no output schema), the description is insufficient. Missing details on return format, pagination behavior, and error conditions.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 33% (3 of 9 params have descriptions). The tool description adds no extra meaning beyond what's in the schema, failing to compensate for low coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'transactions for a Plaid-linked item within a date range'. It distinguishes itself from sibling tools like plaid_accounts, plaid_balances, etc., which operate on different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    There is no guidance on when to use this tool versus alternatives, no prerequisites mentioned, and no caveats like handling of large date ranges or authentication requirements.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It fails to disclose that api_key and api_secret are required for authentication, nor does it mention rate limits, error behavior, or what happens with invalid URLs.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence with no wasted words. However, it could be slightly restructured to include more information without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and annotations, the description should provide more context about return values, required authentication, and potential errors. It is too brief for an agent to use effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. The description only mentions 'feed URL' for the url parameter, ignoring api_key and api_secret entirely. It adds minimal meaning beyond the parameter names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Get), the resource (podcast by feed URL), and the source (Podcast Index). It distinguishes itself from sibling tools that search or list podcasts.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like podcast_search or podcast_trending. Does not mention prerequisites, authentication, or error handling.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so description must disclose behavior. It implies a read operation but omits authentication requirements (api_key needed), rate limits, pagination details, or response structure. Minimal behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with purpose. Concise, but could include slightly more detail without losing brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 7 parameters, no output schema, and no annotations, the description leaves significant gaps: response format, pagination behavior, error handling, and authentication are not addressed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with parameter descriptions. The description reinforces some filter parameters but adds no new meaning beyond what the schema already provides. Baseline of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Search') and resource ('sent messages') and lists filter criteria (recipient, sender, tag, status). It distinguishes from sibling Postmark tools like send or stats, but could be more specific about scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like postmark_get_delivery_stats or postmark_list_templates. No exclusions or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description omits behavioral details such as API key requirements, rate limits, error handling, or idempotency. The agent gets no insight beyond the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise with two sentences, no unnecessary words, and the key action is stated upfront. Every sentence earns its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite having 11 parameters and no output schema, the description fails to explain return values, authentication flow, or expected outcomes. It is too minimal for the tool's complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the baseline is 3. The description's mention of HTML and plain text adds minor reinforcement but is redundant with schema descriptions. No additional semantic value beyond what the schema provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it sends transactional emails via Postmark, with support for HTML and plain text. This is specific and distinguishes it within the Postmark toolset, but does not explicitly differentiate from other email-sending tools in the broader sibling list.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for behavioral disclosure. It does not specify whether the input list is modified or a new list is returned, nor does it mention randomness properties or output format. The minimal phrasing leaves important behavioral traits ambiguous.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no wasted words. However, it is borderline under-informative for the lack of context, slightly reducing the score from a perfect 5.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of an output schema and annotations, the description should explain the return value and behavior more thoroughly. It does not confirm that a new shuffled array is returned, which is essential for an AI agent to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% (empty parameters object), so the description must compensate. It only restates the parameter name ('list' as synonym for 'items') without adding meaning. No details about accepted item types, constraints, or the effect on the input array are given.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool shuffles a list randomly, using a specific verb 'shuffle' and resource 'list'. It distinguishes itself from sibling tools like 'random_pick_from_list' which picks a single element rather than reordering the entire list.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. Among many random utility siblings, there is no mention of when shuffling is appropriate or how it differs from random selection or other random operations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must fully disclose behavior. It implies a read operation ('Get details') but does not specify what 'details' includes, nor mention authentication, rate limits, or any other behavioral traits. The api_key parameter is not mentioned in the description.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, front-loaded, with no unnecessary words. It is efficient, though it could benefit from a brief mention of the api_key requirement without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and annotations, the description is too minimal. It does not explain what details are returned, and the api_key parameter is not addressed. For a tool with only 2 parameters, the description should provide more context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (only 'id' has a description). The description reinforces that 'id' can be an ID or slug, but adds nothing about the 'api_key' parameter, which has no schema description. The description does not compensate for the low coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Get details for a specific game by RAWG ID or slug.' It uses a specific verb ('get') and resource ('details for a specific game'), and distinguishes it from siblings like rawg_search_games and rawg_upcoming_games.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description does not mention when not to use it or suggest sibling tools for different use cases (e.g., searching, upcoming games).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so the description carries full burden. It only says 'Read posts', implying read-only but not explicitly stating behavior like rate limits, authentication needs (access_token required), or result format. Minimal transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence is concise but too brief. It lacks structure and omits necessary detail. While front-loaded with purpose, it sacrifices completeness for brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 6 parameters, no output schema, and sibling tools, the description is incomplete. It does not explain how parameters affect results, output format, or differences from reddit_search, making it insufficient for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is low (33%). The description adds no meaning to parameters beyond what the schema provides. It does not explain 'sort', 'limit', 'after', or 't', which are critical for using the tool correctly.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states 'Read posts from a Reddit subreddit', which is a specific verb+resource. It distinguishes from sibling tools like reddit_comment, reddit_post, and reddit_search, indicating a distinct read action on a subreddit.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like reddit_search. The description does not mention context, prerequisites, or exclusions, leaving the agent to infer usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. Description does not disclose behavioral traits beyond voting (e.g., idempotency, rate limits, side effects of downvoting). The dir parameter values are documented only in schema.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no wasted words. However, it may be overly concise at the expense of necessary details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 3 required params and no output schema or annotations, the description is inadequate. Missing explanation of access_token, id format, and behavioral details like voting constraints.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 33% (only dir described). Description adds no extra meaning to access_token or id, which remain unexplained despite being required.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Vote' and the resource 'Reddit post or comment', distinguishing it from sibling tools like reddit_post (create post), reddit_comment (comment), or reddit_read (read).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives. Does not mention prerequisites, cases where voting is inappropriate, or compare to siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description lacks behavioral details such as side effects (e.g., does setting a variable trigger a redeploy?), overwrite behavior, or required permissions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The single-sentence description is concise but too brief for a tool with four parameters, sacrificing necessary detail for brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Missing output schema and annotations, and the description does not cover return values, error cases, or prerequisites. The tool is not fully contextualized among Render siblings.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (key and value have descriptions, api_key and service_id do not). The description adds no extra meaning beyond the schema; it does not explain api_key or service_id.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Set an environment variable on a Render service' clearly states the verb (set) and resource (environment variable), and it is distinct from sibling tools like render_list_env_vars which list variables.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., render_list_env_vars for viewing, render_trigger_deploy for deploying). No prerequisites or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description fails to mention critical behavioral traits: predictions are asynchronous, require polling, may incur costs, and have rate limits. The description 'create a prediction' is too vague for a computational tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no waste, but it is overly minimal. It is not structured with bullet points or sections, making it less scannable. It earns a 3 for being concise but not well-structured.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 6 parameters, no output schema, and no annotations, the description is insufficient. It does not explain the return value, the asynchronous behavior, error scenarios, or how to handle the prediction ID. A more complete description is needed for a creation tool that triggers background processing.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no parameter semantics beyond the input schema. With 50% schema description coverage, the description should compensate for undocumented parameters like webhook and stream, but it does not.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'Run' and clearly identifies the resource 'a Replicate model' and the action 'creating a prediction'. It distinguishes this tool from siblings like replicate_get_prediction and replicate_cancel_prediction by focusing on creation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives such as replicate_get_prediction for checking results. The description lacks any context about prerequisites or comparison with sibling tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Without annotations, the description must cover behavioral traits. It only says 'recent' without defining recency, omits that the api_token is required, and does not disclose the effect of cursor on pagination or the fact that listing is read-only.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise and front-loaded. However, it sacrifices necessary detail, making it slightly under-specified for a 2-param tool with no annotations.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has two parameters, no output schema, and a sibling set including creation and single-get. The description fails to clarify the output format, explain pagination via cursor, or differentiate its scope from other prediction tools. It is not complete enough for reliable use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description adds no explanation for 'api_token' or 'cursor'. It repeats the parameter names implicitly but provides no additional semantic context beyond what the schema already shows.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'List recent predictions for a Replicate account.' The verb 'list' and resource 'predictions' are specific, and it differentiates from siblings like 'replicate_create_prediction' (create) and 'replicate_get_prediction' (single).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidance is provided. The description does not mention when to list vs. get a specific prediction, nor does it explain pagination or the role of the cursor parameter. The agent receives no cues about alternatives.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It only discloses that this is a read operation ('Get'), but lacks details on authentication needs (api_key), rate limits, error conditions, or any side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence that front-loads the key purpose. However, it could benefit from slightly more structure (e.g., listing parameters) without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Without an output schema and with minimal description, the agent lacks information about what the tool returns (e.g., email fields, success/error formats) and any prerequisites. This is inadequate for a simple fetch tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. The description implies that 'email_id' is the identifier (by ID), but provides no explanation for 'api_key' or any parameter format. With two parameters, the description should compensate for the missing schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get a sent email by ID from Resend' clearly states the action (Get), the resource (sent email), and the identifier (by ID). It distinguishes this from sibling tools like resend_send_email and resend_list_domains.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or appropriate contexts, leaving the agent to infer usage from the name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; the description does not disclose behavioral traits such as rate limits, authentication requirements (api_key parameter implies auth but not explicit), or what happens on failure (e.g., match not found).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that front-loads the core action. It could be slightly more informative without being verbose, but it avoids unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 3 parameters, no output schema, and zero schema descriptions, the description is too brief. It lacks details on what 'details' are returned, how to use region/api_key, and any behavioral context. Incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%; the description only mentions 'match ID' but does not explain the 'region' or 'api_key' parameters, their expected values, or constraints. No added meaning beyond field names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves details for a specific Riot match by match ID. It distinguishes from sibling Riot tools like riot_match_history (which lists matches) by emphasizing 'specific' match via ID.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like riot_match_history, riot_summoner, or riot_ranked. No context for selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No behavioral traits are disclosed beyond the basic action. There is no mention of rate limits, authentication requirements (api_key is in schema but not described), error states, or read-only nature. The description fails to provide behavioral context that annotations would typically cover.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence of 12 words is very concise. The key elements are front-loaded. However, it could be slightly more structured or include a brief note on the api_key.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple lookup tool with 3 parameters and no output schema, the description is minimally adequate. It lacks details on the return value (no output schema), error handling, or necessary authentication context, making it incomplete for an agent to use confidently.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description maps 'game name' and 'tag line' to the gameName and tagLine parameters, but it does not mention the api_key parameter. With 0% schema description coverage, the description partially compensates but misses one parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves a Valorant account using game name and tag line. It is specific to Valorant, differentiating it from other Riot tools like riot_summoner. However, it doesn't specify what 'account' data is returned.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, no description of prerequisites, and no exclusions. Given the sibling list includes other Riot game tools, the lack of usage context is a significant gap.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral disclosure. It only states 'search by text' but does not mention return format, pagination, sorting, authentication needs, rate limits, or potential side effects. This is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no extraneous information. However, it is overly brief and sacrifices completeness for brevity.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters, no output schema, and no annotations, the description is far from complete. It does not explain the purpose of optional parameters, expected output, or behavior when parameters are omitted.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 40% (only workspace_gid and text have descriptions). The description does not add meaning beyond the schema; it merely restates 'search by text'. It fails to explain optional parameters like completed, limit, api_key, which are undocumented.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches tasks by text within an Asana workspace. It distinguishes from sibling tools like 'list_asana_tasks' (which likely lists all tasks) and 'get_asana_task' (single task). The verb 'search' and resource 'tasks' are specific.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as 'list_asana_tasks' or 'get_asana_task'. It does not mention prerequisites, exclusions, or context for selection.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 4 parameters, no output schema, and no annotations, the 5-word description is insufficient. It omits details on search scope, parameter behavior, and what results look like.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 25% (1 of 4 parameters has a description). The description does not compensate for this gap; it adds no information about keyword, severity, pagination, or result format.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search' and the resource 'NVD CVE database', making the tool's purpose unambiguous and distinct from sibling tools like get_cve_detail or get_recent_cves.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., get_cve_detail for specific CVEs or get_recent_cves for recent entries). There is no mention of prerequisites or exclusions.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and annotations, the description fails to provide sufficient context about what the tool returns, such as venue structure or field details. The agent is left without enough information to interpret the response.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 2 parameters with 0% description coverage. The description does not explain what each parameter (id, api_key) represents or how to obtain them, leaving the agent without necessary semantic information.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get a SeatGeek venue by ID' clearly states the verb and resource, distinguishing it from sibling tools like seatgeek_search_venues which search for venues. It is specific and unambiguous, though could be enhanced with more context.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies use when you have a venue ID, but does not explicitly state when to use it over alternatives like seatgeek_search_venues. No exclusions or prerequisites are mentioned, making the guidance implicit.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise and front-loaded with the core action. However, it could be slightly expanded to add value without losing conciseness, such as mentioning default date range.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and 4 parameters including optional aggregation, the description does not explain the return format or what 'statistics' includes. It is incomplete for an API that returns a non-trivial response.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema descriptions cover all parameters comprehensively (100% coverage), so the tool description adds no additional semantic value. The baseline score of 3 is appropriate given the schema already provides meaning.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves SendGrid email statistics for a date range. It distinguishes itself from sibling tools like sendgrid_add_contact or sendgrid_send_email by focusing on statistics, but could be more specific about the metrics returned.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus other SendGrid tools. There is no mention of alternatives or context such as needing to set up statistics tracking first.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description carries full burden. It only states 'Get', implying read-only, but fails to disclose any behavioral traits such as rate limits, error handling, or response structure. Minimal value beyond the schema.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence. It is efficient but could benefit from additional context without becoming verbose. Front-loads the purpose effectively.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple getter with two parameters and no output schema, the description is minimally adequate but lacks information about return values or error conditions. The tool is straightforward, so completeness is acceptable but not thorough.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description adds no extra meaning beyond the schema; it merely restates the identification method already covered in the parameter descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and resource ('SendGrid email template') and specifies identification method ('by ID'). It implicitly distinguishes from list functions but doesn't explicitly contrast with siblings.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance provided on when to use this tool versus alternatives like sendgrid_list_templates. The description lacks any context about prerequisites or typical usage scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must carry the full burden of behavioral disclosure. It only states 'List dynamic email templates' but does not reveal any behavior: whether it is read-only, rate limits, pagination, or what happens if no templates exist. This is insufficient for an agent to understand the tool's behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very short (one sentence) and contains no unnecessary words. However, it is too terse and lacks important details that could be added without increasing length significantly. Still, it earns points for being concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 2 parameters and no output schema, the description is minimally acceptable but incomplete. It does not specify return format, pagination, error handling, or any other contextual details. A more complete description would at least hint at what the agent can expect as a response.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% description coverage, so the baseline is 3. The description does not add any additional meaning beyond what the schema already provides for api_key and page_size. No defaults or constraints beyond schema are explained.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists dynamic email templates in SendGrid. It identifies the resource and action, and distinguishes it from siblings like sendgrid_get_template (single template) and sendgrid_list_contacts (contacts). However, it does not specify details like whether it returns all templates or paginated results.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. For example, it does not mention that sendgrid_get_template should be used for retrieving a single template by ID, or that this tool is for listing all dynamic templates. The description is standalone without context on usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral disclosure. It only lists actions but does not describe side effects, permissions, rate limits, or state changes (e.g., resolve_issue is modify). This is insufficient for safe invocation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, concise and to the point. However, it could be structured with bullet points for clarity. It avoids unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (9 params, no annotations, no output schema), the description is too sparse. It omits parameter dependencies (e.g., issue_id required for get_issue), pagination behavior, return format, and does not cover the full scope of actions.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% description coverage for all 9 parameters, so the description adds no new meaning. Baseline 3 is appropriate; the description does not enhance understanding of parameters beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states the tool interacts with the Sentry REST API and lists specific actions (list projects, issues, get details, events, resolve). This clearly distinguishes it from sibling tools that target other APIs. However, the verb 'Interact' is generic and the description could be more explicit.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of scenarios, prerequisites, or exclusions. The tool is expected to be selected based on the 'Sentry' keyword, but explicit usage context is missing.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    In absence of annotations, the description only states validation and local storage. Does not disclose error behavior, persistence details, or side effects. Leaves significant behavioral gaps.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences, front-loaded with purpose. No unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple registration tool with one parameter and no output schema, the description covers basic purpose but lacks error handling, storage semantics, and integration notes. Adequate but not thorough.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds 'from a YAML string' and 'validates required keys', but these add little beyond the schema's parameter description. No extra format or structure hints for the YAML content.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states it registers a SEOPass pack from a YAML string. Mentions validation and storage. Differentiates from siblings like seopass_run and seopass_status by indicating it's a setup step. However, it doesn't explicitly distinguish from other similar register/save tools like uxpass_register_pack.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Implies use before seopass_run, but provides no explicit when-to-use or when-not-to-use guidance. No mention of prerequisites or alternatives.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description must disclose behavior. It only says 'Get' implying read-only but fails to mention any behavior traits such as pagination, rate limits, or error handling. No mention of what happens with invalid IDs.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    One sentence with 8 words is very concise, but lacks essential information. Being too brief reduces its usefulness despite efficient structure.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema and 6 parameters, the description is severely incomplete. It does not describe the output structure, filtering behavior, or any edge cases. The tool's purpose is clear but all other context is missing.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50%, and the description adds no parameter semantics beyond the schema. It does not explain the effect of optional parameters like platform, emulators, video_only, or how 'top' limits results.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the tool gets a leaderboard for a Speedrun.com game category, using a specific verb and resource. It distinguishes from sibling tools like speedrun_get_game or speedrun_list_runs.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. No mention of prerequisites (e.g., needing game and category IDs) beyond the schema, but that is implied. No exclusions or context for filtering parameters.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It only states the basic function without disclosing authentication requirements, rate limits, or side effects. The agent learns nothing beyond the obvious read operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no extraneous information. It is optimally concise and front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple get tool, the description is incomplete. It lacks details on return format, error handling, and usage context. With no annotations or output schema, the agent is left without important operational information.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description must explain parameters. It does not. There is no mention of how to obtain an album_id or the format of bearer_token. The agent receives no semantic help beyond the parameter names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Get metadata and track listing for a Spotify album.' It uses a specific verb ('Get') and identifies the resource ('Spotify album'), distinguishing it from sibling tools like spotify_get_artist, spotify_get_playlist, and spotify_get_track.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description offers no guidance on when to use this tool versus alternatives. It does not mention prerequisites, suitability, or exclusion criteria. The agent receives no help in deciding to invoke this tool over others.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Only one parameter (type) is described in the schema; the description adds no meaning for query, limit, offset, or market. With 17% schema coverage, the description should compensate but does not.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search', the resource 'Spotify', and the content types 'tracks, albums, artists, or playlists'. It distinguishes from sibling tools like spotify_get_album by indicating it covers multiple types.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this vs specific getter tools (e.g., spotify_get_track). No mention of when not to use or prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must convey behavioral traits. It only says 'Transform', omitting details like whether the operation is destructive to the source image, cost implications, rate limits, auth requirements, or the effect of key parameters like strength. For a tool with 9 parameters and 22% schema coverage, this is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. Given many stock-related siblings, it should indicate it is for finding ticker symbols, not for fetching price data, but it does not.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must fully disclose behavioral traits. However, it only states the tool lists products, omitting critical details such as whether it is read-only, rate limits, pagination, or authentication requirements. The agent cannot assess safety or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at three words, which achieves brevity but lacks necessary detail. It front-loads the core action but is too minimal to be considered well-structured for effective agent use.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with four parameters, including required authentication and pagination options, the description is incomplete. It does not explain return format (no output schema), filtering, or pagination behavior, leaving the agent with insufficient context to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no meaning beyond the parameter names from the schema (e.g., 'limit' is not explained as a pagination limit, 'active' is not clarified as a filter). Given 0% schema description coverage, the description fails to compensate by defining parameter roles or valid values.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List Stripe products.' uses a specific verb ('List') and clearly identifies the resource ('Stripe products'). It effectively distinguishes this tool from siblings like 'stripe_charges', 'stripe_customers', etc., which target different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., secret_key required), pagination behavior (limit, starting_after), or filtering options (active). The agent is left to infer usage from the schema alone, which lacks explanations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must cover behavioral traits. It only states 'List Stripe subscriptions' without disclosing read-only nature, required authentication (secret_key), or any side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (4 words) and front-loaded, but it sacrifices useful detail. Nonetheless, it is efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, no annotations, and low parameter coverage, the description is insufficient. It does not explain pagination (starting_after), filtering (customer, price), or the required secret_key.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 17% (only 'status' has a description). The description does not add any parameter information, failing to compensate for the low coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List' and the resource 'Stripe subscriptions', distinguishing it from sibling tools that list other Stripe objects (charges, customers, invoices, etc.).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like stripe_charges or stripe_invoices. No mention of filtering, pagination, or prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as whether the report is read-only, requires specific permissions, or has size limits. It merely states the action without additional context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that is front-loaded and easy to parse. While efficient, it could include slightly more informative content without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's low complexity (one parameter, simple action) and absence of an output schema, the description is adequate but minimal. It does not clarify that a successful run is needed or that the report is an HTML string.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% for the single parameter run_id, and the description does not add new meaning beyond what the schema already provides. The baseline of 3 is appropriate as no extra value is added.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets an HTML report for a TestPass run, using a specific verb and resource. However, it does not explicitly distinguish from sibling tools like testpass_report_json or testpass_report_md, though the name implies the format.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., JSON or MD report tools), nor does it mention prerequisites like checking run status. Agents must infer from context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description must carry the full burden. It fails to disclose behavioral traits such as whether it returns a list or string, how it handles invalid input, or if it deduplicates email addresses. The simple 'extract' leaves too much ambiguity.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise: one sentence with no filler. Every word is functional and to the point. Appropriate for such a simple tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite the tool's simplicity (1 param, no output schema, no nested objects), the description lacks completeness. It does not specify the return format (e.g., JSON array of strings), whether duplicates are removed, or how edge cases like no emails are handled. The agent is left guessing.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema coverage is 0%, meaning the description adds no additional meaning beyond the parameter name 'text'. The param is just a string, but no format, length, or content guidelines are provided. The description offers no compensation for the low schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the function: 'Extract all email addresses from a text.' It uses a specific verb ('extract') and resource ('email addresses'), distinguishing it well from sibling tools like text_extract_phone_numbers or text_extract_urls.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. There is no mention of prerequisites, limitations, or context where this extraction is appropriate vs other regex or parsing approaches.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, and the description does not disclose behavior beyond the basic function. It does not mention required API key, rate limits, return format, or any side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence. While appropriate for a simple tool, it may be too brief given the context of siblings and missing parameter guidance.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is incomplete: no output schema, sibling differentiation is minimal, and parameter semantics are lacking. An agent would not know how to use this tool effectively or what to expect as output.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With only 33% schema coverage, the description adds no additional meaning to the parameters. The 'units' and 'api_key' parameters are unexplained, and the description does not compensate for the missing schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets realtime weather from Tomorrow.io, using a specific verb and resource. It distinguishes from sibling tools like tomorrow_forecast and weather_current.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is given on when to use this tool versus alternatives such as tomorrow_forecast, tomorrow_history, or other weather tools. No exclusions or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden, but it only states 'Interact with the Trello REST API'. It does not disclose rate limits, destructive nature of create/update actions, error handling, or authentication specifics beyond parameter names.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that front-loads the purpose. It could include more detail without losing conciseness, but it is efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 17 parameters, no output schema, and no annotations, the description is too minimal. It does not explain which parameters are required for each action, nor does it provide context for the complex multi-action behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all parameters, so the baseline is 3. The description adds no additional meaning beyond the schema, merely listing action names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it interacts with the Trello REST API and lists specific actions (list, get, search, create, update) and resources (boards, lists, cards). It is distinct from sibling tools like airtable_action, but does not explicitly differentiate from them.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. Required parameters like api_key and token are mentioned in the schema but not highlighted in the description as prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description does not disclose any behavioral traits beyond the basic function. Important details like whether questions are random, rate limits, or if there's pagination are omitted.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with no filler. It is concise but could be improved by adding brief parameter context without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has no output schema and 0 required parameters. The description does not explain the expected return structure (e.g., array of question objects) or mention the existence of the sibling 'trivia_categories' tool for category IDs. For a data-fetching tool, this is insufficiently complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 50% (only difficulty and type have descriptions that repeat enum values). The description adds no additional meaning about parameters like 'amount' or 'category' (e.g., what category numbers map to or that 'amount' controls number of questions).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get trivia questions from Open Trivia DB.' It specifies the verb (Get), resource (trivia questions), and data source (Open Trivia DB), and distinguishes from the sibling 'trivia_categories' tool which likely fetches categories.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., trivia_categories) or when not to use it. The description only states what it does, not contextual usage conditions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden, but it only says 'create,' implying mutation without details on side effects, error handling (e.g., duplicate name), permissions, or response format. Significant behavioral gaps.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise single sentence with no wasted words. However, the extreme brevity sacrifices necessary detail, so while structurally efficient, it is under-specified.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has 4 required parameters and no output schema or annotations. The description fails to explain how to provide the required fields (e.g., valid api_key, org meaning), any constraints, or what happens on success/failure. Incomplete for a creation operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 50% (only name and group have descriptions). The description adds no extra meaning beyond the schema. For undocumented parameters like api_key and org, the agent has no guidance on their purpose or format.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it creates a new Turso database, distinguishing it from sibling tools like turso_list_databases, turso_execute_sql, etc. The verb 'create' and resource 'new Turso SQLite edge database' are specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, no prerequisites mentioned (e.g., need for existing org/group), and no exclusions. The description is too brief to help an agent decide contextually.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description does not disclose key traits such as authentication requirements (implied by client_id/client_secret parameters), rate limits, or behavior when no results are found. This is insufficient for a tool with no annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, appropriate for a straightforward search tool. However, it could be slightly expanded with essential context without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With five parameters and no output schema or annotations, the description is far from complete. It fails to explain inputs, authentication, or output format, leaving significant gaps for an agent to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description provides no explanation of the five parameters (game_id, user_login, first, client_id, client_secret). While some names are self-explanatory, the agent is left uninformed about authentication requirements and parameter usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the tool searches for live streams on Twitch, with a specific verb and resource. It is distinct from sibling tools like twitch_search_games, twitch_get_stream, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as twitch_get_stream or twitch_channel_info. The description lacks context for appropriate usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavioral traits. It only says 'Get details' without specifying what details are returned, whether authentication is required (api_key is optional), or any constraints like rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no wasted words. However, it is so minimal that it sacrifices clarity; slightly more structure could improve understanding without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of an output schema, the description should indicate the type of details returned (e.g., rating, ABV, brewery). It fails to provide a complete picture, making it difficult for an agent to know what to expect.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (only 'bid' has a description, 'api_key' is undocumented). The description adds no additional meaning for either parameter, missing an opportunity to clarify the role of api_key.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get details') and the resource ('a specific beer on Untappd'), distinguishing it from sibling tools like untappd_search_beer (search) and untappd_beer_activities (activities).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., search for finding beer IDs) or when not to use it. The description lacks context about prerequisites or expected input.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden but only states 'Produce messages', omitting critical behavioral traits such as idempotency, error handling, authentication requirements (implied by api_key), or impact on existing messages.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but too sparse. It lacks any structural elements like sections or examples that would aid an AI agent.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 5 required parameters and no output schema, the description fails to explain how to obtain critical inputs (e.g., api_key, cluster_id) or what the tool returns on success or failure. The tool is under-specified for its complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is only 20%; only the 'messages' parameter has an inline description. The other four required parameters (api_key, email, cluster_id, topic) lack explanation of their purpose or format beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'Produce messages' and identifies the resource 'Upstash Kafka topic', clearly distinguishing this tool from siblings like 'upstash_kafka_list_topics' which lists topics.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. It does not mention contexts like prerequisites, batching, or when to avoid producing messages.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description bears full responsibility. It only states the action without disclosing side effects (e.g., overwriting existing keys, removing TTL), return value, or authentication details. This is insufficient for a write operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise at 9 words, but it is too minimal for a tool with 6 parameters and no annotations. While it is front-loaded with the action, it does not earn its place by providing sufficient detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (6 params, write operation, no output schema, no annotations, low schema coverage), the description is severely incomplete. It omits return value, constraints, and disambiguation from siblings.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With only 33% schema description coverage, the description fails to explain the roles of parameters like api_key, email, db_id, and key. It adds no value beyond the schema, and the schema itself lacks descriptions for most parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Set a key-value pair') and the resource ('Upstash Redis database'), effectively distinguishing it from sibling tools like upstash_redis_get, upstash_redis_del, upstash_redis_incr, and upstash_redis_list_keys.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behaviors such as read-only nature, authentication needs, or error handling. It mentions none of these, leaving the agent uninformed about side effects or requirements.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no unnecessary words. It is front-loaded with the core purpose, achieving maximum conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the minimal description, no annotations, and no output schema, the tool lacks context about return values, expected input format, and related operations. It is insufficient for an agent to use effectively without additional knowledge.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must add meaning. It only explains 'uuid' implicitly ('by UUID') but fails to mention 'api_key' or clarify what 'uuid' refers to. The description adds almost no value over the parameter names.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get the result') and the resource ('a urlscan.io scan by UUID'). It is specific about the input method (UUID), making it easy to understand what the tool does.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus sibling tools like urlscan_scan or urlscan_search. There is no mention of prerequisites or typical workflow context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden but only says 'submit for scanning'. It does not disclose scanning duration, impact on the URL, rate limits, or response behavior (e.g., whether it returns immediately or asynchronously).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 7 words, which is very concise. While clear, it could benefit from slightly more structure, such as mentioning the required parameter.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is insufficient for a tool with 3 parameters, no output schema, and no annotations. It does not explain return values, usage of api_key, or the meaning of visibility options beyond what the schema provides.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is low (33%), and the description adds no extra meaning beyond the schema. The 'visibility' parameter is already documented in the schema, while 'url' and 'api_key' have no description in either place.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (submit a URL) and the service (urlscan.io), which is specific and distinguishable from sibling tools like urlscan_get_result and urlscan_search.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., urlscan_get_result to retrieve results). There is no mention of prerequisites or typical workflows.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behaviors like authentication (api_key) or rate limits, but it only states the core action. No mention of whether it triggers a scan or retrieves an existing report, or any potential side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it sacrifices necessary detail. It is front-loaded but not sufficiently informative for the agent to use correctly.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of sibling tools and the lack of an output schema, the description is incomplete. It does not clarify the difference between this tool and virustotal_url_report, nor does it describe the report format or any constraints.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage for its two parameters. The description fails to explain that 'domain' is the target domain or that 'api_key' is an optional authentication key, leaving the agent to infer from the tool name.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get a VirusTotal report for a domain' clearly states the action (get a report) and the target resource (domain). It distinguishes itself from sibling tools like virustotal_scan_ip, virustotal_scan_url, and virustotal_url_report by specifying domains.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, typical use cases, or when to opt for scanning an IP or URL instead.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Lacks disclosure of critical behaviors like authentication requirements (api_key is optional but likely needed), rate limits, error handling, or what constitutes a 'report'. No annotations to supplement.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise at one sentence, but this brevity sacrifices necessary detail. It is front-loaded and avoids fluff, but leaves significant gaps in understanding.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of annotations, output schema, and parameter descriptions, the description is incomplete. It does not cover return format, error conditions, or practical usage context for an AI agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description does not explain the parameters beyond what the input schema provides. With 0% schema description coverage, the agent gets no additional semantic information about 'ip' or 'api_key'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states 'Get a VirusTotal report for an IP address', which distinctly identifies the tool's action and resource, differentiating it from sibling tools like virustotal_scan_domain or virustotal_scan_url.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as virustotal_scan_domain. The description does not mention prerequisites, limitations, or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description does not disclose behavioral aspects such as side effects, rate limits, or the need for authentication (beyond the parameter). It implies a non-destructive read but offers no explicit assurance.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, but it lacks structure and front-loads only the verb and resource. It could be improved by adding details about return value or usage.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity of a media retrieval tool, the description is underspecified. It does not explain how to obtain media_id, the format of the download URL, or potential error states like expired media.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description adds minimal value. It mentions 'by ID' for media_id but does not explain bearer_token or provide any context beyond what the schema names imply.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (get), the resource (WhatsApp media object by ID), and the output (download URL and metadata). It effectively distinguishes this tool from sibling tools like whatsapp_send_media or whatsapp_upload_media.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. The description does not mention prerequisites, when not to use it, or provide any context for the bearer_token parameter.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. The description does not disclose behavioral traits such as authentication requirements, handling of missing media_id/media_link, rate limits, or return behavior. It only states the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (multiple media types, optional parameters, no output schema), the description is too brief. It does not cover important usage constraints like whether both media_id and media_link can be provided or what happens if neither is provided.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (4 of 8 parameters have descriptions). The description adds no parameter semantics, e.g., it doesn't explain the relationship between media_id and media_link, or when caption is applicable.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (send), resource (media message), and lists supported types (image, video, audio, document, sticker). It distinguishes from sibling tools like whatsapp_send_text, whatsapp_send_template, and whatsapp_upload_media.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives like whatsapp_upload_media (for uploading first) or whatsapp_send_template. No context on prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden, but it only states the high-level action. It fails to disclose critical behavioral traits such as that the media is fetched from a URL (media_url), authentication requirements (bearer_token), or potential limitations (file size, supported types, error behavior).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it is too terse given the tool's complexity. It could benefit from a second sentence clarifying the URL-fetching behavior or parameter roles without being overly verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's 5 parameters, no output schema, and no annotations, the description is incomplete. It does not explain how the media ID is returned, the prerequisites for using the bearer token, or the typical workflow (upload first, then use ID in send_media). This leaves significant gaps for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has only 40% parameter description coverage, yet the description adds no context for the parameters (e.g., bearer_token, phone_number_id, filename). It does not explain the purpose of each parameter beyond what the schema already provides, leaving the agent with insufficient information.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (upload media file), the target system (WhatsApp), and the result (get a media ID for use in messages). It is specific and distinct from sibling tools like whatsapp_send_media which sends media to a user.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, placing the full burden on the description. The description only states the action without disclosing behavioral traits such as whether the operation is read-only, if it requires authentication (though api_key is optional), pagination behavior, or any side effects. For a list operation, such transparency is minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. However, it is possibly too terse given the lack of parameter semantics and behavioral details. It is concise but at the expense of completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and low parameter coverage, the description does not explain what the tool returns (e.g., an array of branch objects, pagination info) or any usage caveats. An AI agent would have to infer the output format from the tool name alone.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description does not explain the meaning of the api_key and project_id parameters. It does not mention that api_key is for authentication or that project_id identifies the context. The description adds no value beyond the schema itself.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List all branches in a Neon project' clearly states the specific verb (list), resource (branches), and scope (Neon project). It effectively distinguishes this tool from siblings like neon_create_branch (create) or neon_get_project (get project details).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies when to use this tool (listing branches for a project), but it does not explicitly provide guidance on when not to use it or mention alternative tools for related tasks (e.g., getting project details). The context is clear but lacks exclusions or contextual comparisons.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits, but it only states the basic lookup purpose. It does not mention authentication requirements (api_key), error handling, or any side effects, leaving critical context unknown.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, which is efficiently structured. However, it is too minimal, sacrificing valuable information that could be added without significant verbosity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters, no output schema, and no annotations, the description is incomplete. It fails to explain parameter semantics, usage scenarios, or expected output, making it insufficient for an agent to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, yet the description only adds meaning for the 't' parameter (by title). The other three parameters (type, y, api_key) remain unexplained, severely limiting understanding of how to use the tool correctly.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves an OMDB movie/show by title, using a specific verb and resource. It distinguishes from sibling tools like omdb_by_id (by ID) and omdb_search (search query) through the phrase 'by title'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the tool is for title-based lookups, but does not explicitly state when to use it versus alternatives like omdb_search or omdb_by_id. No guidance on prerequisites or exclusions is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must fully disclose behavioral traits. It only states the basic operation (upsert) without detailing mutation safety, idempotency, rate limits, or authentication needs. The api_key and index_host parameters are not discussed in the description.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, but it is minimally viable. It lacks any structural elements (e.g., front-loaded key points) that could improve utility without adding length.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and the complexity of a mutation tool, the description is incomplete. It does not explain the return value, error scenarios, or vector format requirements beyond what the schema provides.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All parameters have descriptions in the input schema (100% coverage), so the description adds no additional meaning. Baseline of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the verb 'upsert' and resource 'vectors into a Pinecone index', distinguishing it from sibling tools like pinecone_delete_vectors and pinecone_query_vectors.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives (e.g., when to upsert vs query). No prerequisites or context provided beyond the index name, leaving the agent without usage boundaries.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It only states the basic function without disclosing behavioral traits like token expiration, required authentication (client_id/secret), or side effects. The description omits that the token is used client-side and typically returned in the response.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise at one sentence, but it could be more informative without being verbose. It lacks front-loading of key details (e.g., response token).

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has 10 parameters (3 required) and no output schema. The description does not explain the return value (a link_token) or next steps (e.g., using the token in a frontend flow). Given the complexity and lack of schema, more context is needed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 60%, with some parameters having descriptions (e.g., user_client_user_id, client_name). The description adds no additional meaning beyond the schema. Baseline score of 3 is appropriate since the description does not augment parameter understanding.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Create a Plaid Link token') and the resource ('Plaid Link token'). It directly distinguishes from sibling tools like plaid_accounts or plaid_transactions by specifying the creation of a token to initialise the Plaid Link flow.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, such as other Plaid tools. There is no mention of prerequisites (e.g., needing a user) or when to call this before other operations. The description lacks context for appropriate usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the burden, but it only states 'Get details' without disclosing any behavioral traits like authentication requirements, rate limits, or the nature of the return details. The optional api_key parameter is not mentioned.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence of 8 words, front-loaded with the main action. It is appropriately concise with no wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple get-by-ID tool with 2 parameters and no output schema, the description is adequate but lacks details on what 'details' are returned. It assumes prior knowledge of TMDB. Slight gaps in completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain the parameters. The 'id' parameter is not clarified as a TMDB TV show ID, and 'api_key' is not explained. The description adds no value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description provides a specific verb ('Get'), a clear resource ('TMDB TV show'), and the input method ('by ID'). This clearly distinguishes it from sibling tools like tmdb_search_tv (search) and tmdb_movie (movie resource).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as tmdb_search_tv or tmdb_now_playing. The description lacks context for selection, leaving the agent to infer usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations are absent, so the description must disclose behavioral traits. It only states that the tool interacts with the API and lists operations. It does not mention side effects of write actions, rate limits, authentication details, or the unified nature of the tool (action parameter decides behavior). Minimal behavioral disclosure beyond the schema.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise and front-loaded with the tool's purpose. While it could be slightly more structured, it avoids unnecessary verbosity and earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 11 parameters and no output schema or annotations, the description is too sparse. It does not mention parameter dependencies (e.g., base_id and table_name needed for most actions), pagination, or the overall flow of using this tool. Incomplete for a complex tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the baseline is 3. The description lists action types but does not add significant meaning beyond the schema's parameter descriptions. It fails to explain how parameters relate to each action or provide context on usage patterns for the various parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states that the tool interacts with the Airtable REST API and lists specific actions (list bases, list and search records, get a single record, create or update records). This provides a clear verb+resource mapping and distinguishes it from any potential Airtable-specific siblings (though none exist in this list).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives. With no sibling Airtable tools, the description could still explain which action to choose and under what circumstances, but it doesn't. It also fails to mention prerequisites like needing an Airtable personal access token, though that is implied by the required parameter.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description should disclose behavioral traits. It merely states the action without mentioning pagination, authentication requirements, rate limits, or what happens with no results. The description is too minimal to inform an agent of important behaviors.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that is front-loaded with the key purpose. However, given the number of parameters and complexity, a bit more detail could be helpful without being verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is incomplete for a tool with 8 parameters and no output schema. It does not explain behavior like pagination, filtering, or the nature of returned records. Compared to the complexity, more detail is needed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description does not add any additional meaning beyond the schema; it does not mention any parameters or their roles.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search' and the resource 'an Algolia index for records matching a query'. It distinguishes itself from sibling tools like algolia_browse_index and algolia_get_object by focusing on searching records.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as algolia_browse_index, algolia_get_object, or algolia_list_indices. The description lacks context for choosing this tool over others.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden of disclosing behavioral traits. However, it only says 'get upcoming events' and does not mention authentication, rate limits, error handling, or what happens if the artist is not found.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very short (one sentence), which is concise but at the expense of completeness. It is front-loaded but does not earn its place by providing sufficient information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with no output schema and no annotations, the description is too minimal. It does not explain what data is returned (list of events, details, etc.) or any other necessary context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%, and the description does not explain the 'date' or 'app_id' parameters. It only mentions 'artist' implicitly. The description fails to add meaning beyond the raw schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it gets upcoming events for an artist, which is a specific verb+resource combination. It distinguishes from sibling tools like bandsintown_artist and bandsintown_recommended.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit when-to-use or when-not-to-use guidance is provided. The context of when to use this versus the sibling tools is implied but not stated, leaving the agent to infer from the description.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must carry the behavioral disclosure burden. It only states the basic search function, omitting important traits like pagination, result format, case sensitivity, or ordering. The agent is left guessing about the tool's behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple tool (2 params, no output schema, no annotations), the description still feels incomplete. It doesn't explain return values, result formatting, or how search ranking works. Sibling tools suggest a richer ecosystem, but this description doesn't connect.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description adds no extra meaning beyond the schema. It does not elaborate on the 'type' enum or provide examples. No added value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Search), resource (BoardGameGeek), and target (board games by name). It distinguishes this tool from siblings like bgg_game_details or bgg_top_games, which serve different purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, no prerequisites, and no context for typical workflows (e.g., searching first then getting details). This leaves the AI agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It only mentions 'estimate' without disclosing data sources, accuracy, or the need for an API key (present in schema). Behavioral traits like idempotency or country coverage are not addressed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words, but it is too brief given the lack of schema descriptions. It does not fully earn its place by providing enough information for correct usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description bears full responsibility for behavioral disclosure. It mentions 'Get details' but does not indicate whether this is a read-only operation, what authentication is required (though api_key is a parameter), rate limits, or any side effects. The description is too minimal for full transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that directly states the tool's purpose. It is front-loaded and contains no extraneous information. However, given its brevity, it sacrifices detail for conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description lacks important context such as what 'details' are returned, the structure of the output, and how this tool fits into the broader workflow. Given the absence of an output schema and annotations, the description is insufficiently complete for an agent to fully understand the tool's behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, with both api_key and workflow_id having clear descriptions in the schema. The tool description adds no additional information about the parameters beyond the schema, so it meets the baseline but does not exceed it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves details for a single CircleCI workflow by its ID. This distinguishes it from siblings like circleci_list_workflows (which lists workflows) and circleci_get_pipeline (which gets pipeline details), making the purpose specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, no prerequisites, and no mention of scenarios where it should not be used. It simply states what it does, leaving the agent without context for appropriate usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral details like pagination, filtering, output format, or error handling. It only states the action without depth.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise with a single sentence, no fluff. However, it may be overly terse, potentially missing useful context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list operation with 2 required parameters and no output schema, the description is minimal. It lacks details on output structure, pagination, or any nuances that would help in complex scenarios.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with both parameters having descriptions. The tool description adds no additional meaning beyond what is already in the schema, achieving baseline adequacy.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('List'), resource ('workflows'), and context ('for a CircleCI pipeline'). It effectively distinguishes from sibling tools like circleci_get_workflow (single workflow) and circleci_list_pipelines (lists pipelines).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as circleci_get_workflow (for a specific workflow) or circleci_list_jobs (for jobs within a workflow). No when-not-to-use or contextual hints.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must carry the burden of behavioral disclosure. It fails to mention authentication requirements (API key is in schema but not explained), rate limits, pagination, or whether the operation is read-only. The minimal description lacks critical behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence of 7 words with no extraneous information. It efficiently communicates the core purpose without redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of an output schema and annotations, the description provides no context about the return format (e.g., list of form IDs, names, or details). It lacks completeness for a tool that likely returns structured data, and fails to address potential edge cases or limitations.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain the api_key parameter beyond stating its presence in the schema. While the parameter name is self-explanatory, the tool definition adds no value by clarifying its purpose or format, which is necessary given the low coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it lists all forms in a ConvertKit account, using a specific verb and resource. It distinguishes itself from sibling tools like ck_list_subscribers and ck_list_tags by explicitly naming 'forms' as the resource.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as ck_list_sequences or ck_list_tags. The description does not mention scenarios, prerequisites, or exclusions, leaving the agent to infer usage from context alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the burden of disclosing behavioral traits. The description does not mention side effects (e.g., create and update are write operations), authentication requirements beyond the api_key, rate limits, or idempotency. This leaves the agent without critical behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that lists the major actions. It is front-loaded with the API version and clear action categories. However, the phrase 'Interact with' is vague, and a more structured list could be marginally clearer.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has 13 parameters and multiple actions, yet the description provides no guidance on action sequencing or parameter dependencies (e.g., need team_id for get_spaces). Lacking an output schema, the description should help the agent understand the logical workflow, but it does not.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description does not add any meaning beyond what the schema already provides for each parameter. It only gives a high-level overview without elaborating on parameter constraints or usage patterns. Thus, it meets the baseline but does not exceed it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool is for interacting with the ClickUp API v2 and enumerates the key actions (list, get, create, update). It effectively communicates the scope and purpose. However, it could be slightly more specific about the API endpoints and does not differentiate from sibling tools, though the tool name already distinguishes it.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    There is no explicit guidance on when to use this tool versus alternatives. The description implies that it should be used for ClickUp API interactions, but it does not provide context for choosing between actions or when to use other tools. The action enum provides some direction, but the description lacks explicit usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Discloses support for system preamble and conversation history, indicating statefulness. However, with no annotations, it fails to mention rate limits, authentication requirements beyond api_key, or expected behavior (e.g., streaming, token limits). Adds some value but incomplete.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences, front-loaded with the main purpose. No extraneous information. Efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a chat tool with 7 parameters and no output schema, the description lacks information about return values, error handling, or usage context. Incomplete compared to sibling chat tools that include response format.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 71% (5 of 7 params described). Description reinforces preamble and chat_history parameters but does not clarify api_key, model, max_tokens, or temperature beyond their schema descriptions. Baseline 3 with marginal added meaning.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    States 'Chat with a Cohere Command model' which clearly identifies the verb and resource. Supports system preamble and conversation history, distinguishing it from non-chat siblings like cohere_classify and cohere_embed. However, could more explicitly differentiate from cohere_generate.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool over siblings such as cohere_generate, cohere_classify, or other chat tools. The description does not mention context, prerequisites, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It only states 'Convert' but does not disclose whether the tool is read-only, if it modifies state, or any limitations. A conversion tool likely is safe, but the description should explicitly state it does not alter data.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single clear sentence, front-loaded with verb and resource. No wasted words. Appropriate length for a simple tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given low complexity and no output schema, the description should mention what the output looks like (e.g., the converted color string). It also does not differentiate from siblings sufficiently. For a simple tool, it is minimally complete but lacks return value context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%, so description must add meaning. It mentions formats (HEX, RGB, HSL) which gives context for 'from' and 'to' parameters, but does not specify exact string values or constraints. It partially compensates for missing schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a clear verb 'Convert' and specific resource 'color', and lists formats (HEX, RGB, HSL). It distinguishes from siblings like color_mix or color_info by focusing on conversion. However, it doesn't explicitly differentiate from other color tools, leaving some ambiguity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like color_info or color_mix. No mention of prerequisites or context, which is needed given the presence of sibling color tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description implies a read-only lookup, but with no annotations, it does not explicitly state that no modifications occur. It also fails to disclose behavior for invalid inputs or the effect of the format parameter.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise, but it lacks detail on parameters and output, making it under-informative for effective tool selection.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and minimal schema descriptions, the description is incomplete. It does not specify return fields, accepted color formats, or error handling, which is insufficient for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema coverage, the description should explain parameter meanings. It only mentions the overall action, not what 'color' (e.g., hex, name) or 'format' (e.g., json, text) accept, leaving the agent guessing.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get information about a color (name, complementary, etc.)', specifying the verb 'get' and resource 'color information'. It distinguishes from sibling tools like color_contrast_ratio, color_convert, color_mix, and color_palette, which have different purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidance provided. The description does not indicate when to use this tool versus alternatives, nor does it mention prerequisites or limitations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden for behavioral disclosure. It only states the conversion purpose without revealing any behavioral traits (e.g., stateless, read-only, output format, error handling). For a simple conversion, this is minimal; the agent learns nothing beyond the basic intent.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no extraneous words, efficiently conveying the core purpose. It is appropriately sized for a simple conversion tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite the tool's low complexity, the description lacks crucial context: it does not specify supported volume units, output format, or any example. Without this information, the agent cannot reliably use the tool. The absence of output schema further compounds the gap.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the description provides no additional meaning for the three parameters (value, from, to). It does not specify acceptable unit strings, value constraints, or format. The agent has no information beyond parameter names, making it impossible to know valid inputs.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Convert between volume units.' which clearly identifies the verb (convert) and resource (volume units). It effectively distinguishes from sibling tools like convert_length or convert_temperature by specifying 'volume units'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implicitly tells when to use this tool (when needing volume conversion), but it does not provide explicit guidance on when not to use it or suggest alternatives like other conversion tools. Given the presence of many sibling conversion tools, this lack of explicit differentiation is a minor gap.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It does not disclose behavioral traits such as pagination, sorting criteria, rate limits, or what defines 'top'. The agent is left without crucial operational details.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence with no wasted words. It is appropriately concise for a simple tool, though slightly more structure (e.g., listing parameters) would improve scannability.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, no annotations, and only 0% schema coverage. The description omits what information is returned for top players (e.g., names, trophies, ranks). The tool likely returns a list, but the structure is unknown, making it incomplete for confident use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so description must compensate. It clarifies that 'locationId' filters by location, but does not specify the format or allowed values. 'api_key' is implicitly for authentication, but no details on how to obtain it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'top Clash Royale players', and the scope 'globally or by location'. It effectively distinguishes from sibling tool 'cr_player' which targets individual players.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool over alternatives, when to filter by location versus global, or any prerequisites or caveats. The description leaves the agent to infer usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description bears full responsibility. It states a read operation ('Get details') but does not explicitly disclose safety (read-only), authentication needs, rate limits, or what 'details' includes. The description is minimal and lacks sufficient behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, earning its place. However, it may be too brief, lacking details that could improve clarity without sacrificing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description omits explanation of return values. The tool has 3 parameters and no annotations, and the description does not provide enough context for an agent to fully understand usage. Sibling tools exist but are not referenced.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with all parameters having descriptions. The description adds no additional meaning beyond the schema. Baseline of 3 is appropriate as the schema does the heavy lifting.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly specifies the verb 'Get' and the resource 'details for a specific Datadog monitor'. It distinguishes from sibling tools like datadog_list_monitors (list all) and datadog_create_monitor (create), making the purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., datadog_list_monitors for listing, datadog_create_monitor for creation). No prerequisites or exclusions are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. Description does not disclose behavioral traits such as whether it counts weekends, holidays, or requires specific date formats.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, immediate clarity, no extraneous words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with no output schema and low schema coverage, the description is incomplete. Does not explain return value (count or list), date format, or business day definition.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% with no parameter descriptions. Description does not add meaning beyond parameter names, e.g., required date format or range validation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the verb 'Get' and the resource 'business days between two dates'. Distinct from sibling tools like datetime_date_diff.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives like datetime_date_diff or datetime_add_to_date. Missing context about excluding weekends/holidays.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description does not disclose behavioral traits beyond the basic retrieval. It omits details about authentication, rate limits, potential side effects, or response structure, which are important for an agent to use the tool safely.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that is concise and front-loaded. However, it may be too minimal; additional useful details could be added without significantly increasing length.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple retrieval tool with one parameter and no output schema, the description is fairly complete. However, missing context about expected output format or error handling limits its completeness, especially given the absence of annotations.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage, and the description only mentions 'by ID' without explaining what the ID represents (e.g., numeric Deezer album ID format). The parameter 'id' type is number, but no additional context is given to help the agent understand how to obtain or use it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get a Deezer album by ID' clearly states the action (get), the resource (Deezer album), and the identifier method (by ID). It is specific and distinct from sibling tools like deezer_get_artist or deezer_get_track.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool instead of alternatives such as deezer_search or deezer_chart. The description does not specify context cues, prerequisites, or exclusion criteria.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the burden. It states 'Get information' implying a read operation, but does not specify what kind of information (e.g., taxonomy, range, conservation status), rate limits, authentication needs, or data freshness. For a tool with zero annotations, this is a significant gap.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, short sentence with no wasted words. However, it may be too concise, lacking details that could be added without significantly increasing length.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (two parameters, no output schema), the description provides the basic purpose but fails to cover parameter purpose, expected output, or how it differs from sibling tools. It is minimally viable but lacks contextual completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% (no parameter descriptions), but the description offers no elaboration on either parameter (speciesCode, api_key). The agent must guess that speciesCode is an eBird ID and api_key is for authentication. The description does not compensate for the lack of schema documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get information about a bird species from eBird' clearly states the verb (Get), the resource (bird species), and the source (eBird). It distinguishes from sibling tools like ebird_notable_observations and ebird_recent_observations, which focus on observations rather than species info.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, when not to use it, or how it compares to other eBird tools. The agent must infer usage context from the name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions the output format (base64 audio) but does not disclose rate limits, authentication requirements, or potential side effects (e.g., cost per character). The description is insufficient for a tool with external API calls.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise with only two sentences, front-loading the action and output format. No extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 9 parameters, no output schema, and no annotations, the description is too sparse. It doesn't explain how to obtain a voice_id, doesn't mention the need for an API key, and doesn't clarify the structure of the base64 output. The tool is complex but the description is minimal.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no parameter semantics beyond what is in the input schema. The schema already covers 6 of 9 parameters with descriptions (67% coverage). The description does not explain parameter relationships or provide guidance on picking voice_id or model_id.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Convert text to speech'), the resource ('selected ElevenLabs voice'), and the output format ('Returns base64-encoded audio'). It distinguishes itself from sibling tools like elevenlabs_list_voices or elevenlabs_get_voice by specifying the conversion functionality.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like elevenlabs_get_voice or elevenlabs_get_history. There is no mention of prerequisites (e.g., need for a valid voice_id from list_voices) or context for choosing models or parameters.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for behavioral disclosure. It mentions an API key requirement, but omits critical details like whether the operation is read-only, if it returns all codes or paginated, or any side effects. This is insufficient for a tool with no annotation support.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no wasted words. While it could include more detail, it remains concise and to the point.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple but lacks an output schema. The description should indicate what the return value contains (e.g., list of objects with code and name). The current description is incomplete for an agent to understand the full response format.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% (api_key has a description). The description redundantly states 'Requires an API key', adding no new semantic meaning beyond what the schema already provides. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List all supported currency codes and their names' uses a specific verb ('List') and resource ('currency codes and their names'), distinguishing it from sibling tools like exchangerate_convert or exchangerate_historical.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description only states 'Requires an API key' as a prerequisite, but provides no guidance on when to use this tool versus alternative tools like exchangerate_latest or exchangerate_convert. No when-not-to-use or context for choosing this tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description must convey behavioral traits. It fails to mention authentication requirements (beyond the schema), rate limits, return format, or error conditions. The minimal description ('Get all published components') provides only a basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence (8 words) that efficiently conveys the core action. Every word earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with 2 parameters and no output schema, the description is minimal but insufficient. It omits what the tool returns (e.g., list of component objects) and assumes knowledge of Figma's API conventions.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description adds no value beyond the parameter names. It does not explain how to obtain the personal_access_token or file_key, nor does it clarify any constraints or format expectations.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Get') and resource ('published components') with scope ('in a Figma file'). It clearly distinguishes itself from sibling tools like figma_get_node (specific node) or figma_get_file (file metadata).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives (e.g., figma_get_node for a single component). The description only states what it does, not when or why to choose it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but only states 'list', implying read-only. It fails to disclose behavioral traits such as authentication requirements, error handling, or idempotency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no extraneous words. It is efficiently structured and front-loaded with the core purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description omits return value details, pagination, or limits. Given the tool lists projects, potential volume and output format are left unspecified, leaving the agent with gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 50%, and the description adds no extra meaning to the parameters. It does not explain the personal_access_token format or the source of team_id, leaving ambiguity.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('list'), the resource ('projects'), and the scope ('for a Figma team'). It effectively distinguishes itself from sibling tools like figma_get_file or figma_get_comments.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, nor does it mention prerequisites or constraints. The description lacks context for appropriate invocation.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits, but it only restates the schema. It does not mention side effects, permissions, rate limits, or what 'details' include, leaving agents uninformed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at one sentence, with no wasted words. However, its brevity sacrifices detail; it could benefit from a bit more context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple GET operation with two parameters, the description is minimally adequate but lacks details about the return format and any prerequisites (e.g., api_key purpose). It leaves the agent guessing about what 'details' entails.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (app_name has a description, api_key does not). The description adds no parameter information beyond the schema, failing to compensate for the missing api_key description.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get details') and the resource ('a specific Fly.io app'), distinguishing it from sibling tools like fly_list_apps which lists all apps.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives like fly_list_apps or fly_create_machine. The description implies use when you know the app name, but no when-not or prerequisites are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description carries full burden for behavioral disclosure. It does not mention side effects (none expected), rate limits, authentication requirements, or any constraints like maximum gameweek values. The description is too minimal to inform an AI agent about behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise—just 8 words. It is front-loaded with the core action and includes the optional parameter. Every word serves a purpose, with no redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one optional parameter, no output schema), the description is partially complete. It explains what the tool does and the filter option. However, it does not describe the return value structure, which could be useful since there is no output schema. The description is adequate but lacks depth.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single parameter 'gameweek' is described as optional, which adds meaning beyond the schema (which only specifies type number). However, with 0% schema description coverage, the description could have provided more context about the parameter's format or default behavior (e.g., returns all fixtures if omitted).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves FPL fixtures with an optional gameweek filter. It uses specific verb 'Get' and resource 'FPL fixtures'. However, it doesn't explicitly distinguish itself from sibling FPL tools like fpl_gameweek or fpl_bootstrap, which might also retrieve fixture-related data.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, limitations, or typical scenarios. The description is purely functional without usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description fails to disclose behavioral traits such as rate limits, authentication requirements (api_key param unused in description), error handling, or response structure. 'Get' implies a safe read operation, but this is not explicitly stated.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no filler. It efficiently conveys the core functionality without unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of an output schema and annotations, the description is insufficient for a complete understanding. It does not explain what data is returned (song details, metadata) or how to interpret the response. A simple tool still benefits from basic return-value context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description must compensate for missing parameter details. It does not explain that 'id' is a Genius song ID or how to obtain it, nor does it clarify the purpose of 'api_key'. The description adds no value beyond the schema's property names and types.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'Genius song by ID', making the tool's purpose unambiguous. It effectively distinguishes from sibling tools like genius_artist_songs (gets songs by artist) and genius_search (search songs) by specifying ID-based retrieval.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, search vs. direct lookup, or links to related tools (e.g., use genius_search to find a song ID first).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior1/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of disclosing behavioral traits. It fails to mention that this is a read-only operation, whether authentication is required (though access_token param hints at it), what happens if the board_id is invalid, or any rate limits. The description is completely silent on these aspects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that directly states the tool's purpose. There is no unnecessary information, and it is well-structured for quick comprehension.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple GET tool with two parameters, the description is minimal but adequate. It lacks information about what 'details' entails, no output schema, and no error handling context. However, given the tool's simplicity and the presence of sibling tools, a score of 3 is reasonable.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers 50% of parameters (board_id has a description, access_token does not). The description adds no extra meaning beyond the schema. However, the parameter names (board_id, access_token) are relatively self-explanatory, so the baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: retrieving details of a specific Pinterest board. The verb 'Get' and resource 'details of a specific Pinterest board' are specific and distinguish it from sibling tools like list_pinterest_boards (which lists multiple boards) or create_pinterest_pin (which creates a pin).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool vs alternatives (e.g., list_pinterest_boards). It does not mention prerequisites such as needing a board_id obtained from another tool. The description lacks any context about appropriate use cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description does not disclose any behavioral traits such as pagination, rate limits, or authentication requirements beyond the api_key parameter.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence is concise but lacks useful context for the agent; not verbose but could be improved with additional details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with one required parameter and no output schema, the description is minimally adequate but lacks details on return format or usage notes.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 100% coverage with a description for api_key; description adds no further meaning, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the action (list) and resource (all products in a Gumroad account), distinguishing it from siblings like gumroad_get_product (single product) and gumroad_list_sales.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives; lacks when-not to use or mention of other product-related tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully convey behavioral traits. It mentions filtering but omits pagination behavior (though a 'page' parameter exists), rate limits, authentication details beyond requiring an API key, and the nature of the response (e.g., array of sales or paginated results).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise—two sentences with no unnecessary words. The primary action is front-loaded. Every sentence provides information without redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description should clarify the return format or pagination. It mentions filters and implies a list, but lacks details on pagination (page parameter) and response structure. It is adequate but incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% description coverage for all 6 parameters, achieving a baseline of 3. The description adds minimal value by listing the filter types (product, email, date range), but this does not significantly enhance understanding beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists sales from a Gumroad account and can be filtered by product, email, or date range. The verb 'list' and resource 'sales' are specific. However, it does not explicitly differentiate from sibling tools like gumroad_get_sale or gumroad_list_subscribers, but the plural vs singular and filter options provide implicit distinction.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like gumroad_get_sale or gumroad_list_products. It does not mention any prerequisites, exclusions, or context for use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description lacks behavioral information beyond the obvious 'list' operation. With no annotations, it should disclose aspects like read-only nature, authentication via api_key, pagination limits, or response structure. None are provided.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with a single sentence that front-loads the core purpose. While it is efficient, it could include a bit more context without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of an output schema and annotations, the description fails to provide essential details such as response format, pagination, or error handling. This is insufficient for a listing tool with three parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema already describes all three parameters (api_key, product_id, email). The description does not add any additional meaning, examples, or constraints beyond the schema, resulting in a baseline score of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists subscribers for a Gumroad membership/subscription product. It specifies the verb 'list' and the resource 'subscribers', distinguishing it from siblings like gumroad_list_products and gumroad_list_sales.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidance is provided. The description does not mention when to use this tool versus alternatives like gumroad_list_sales, nor does it state prerequisites such as requiring a product_id for a subscription product.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. The description only states the function without disclosing any behavioral traits such as required authentication, rate limits, error handling, or the structure of the response. The tool performs a read operation, but this is not explicitly confirmed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (6 words) and front-loaded with the key verb and resource. It wastes no words, making it efficient for quick understanding. However, it may be too minimal for full clarity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one parameter and no output schema, the description is minimally adequate. It does not describe return values, error conditions, or the depth of user profile data. Given the lack of annotations and schema coverage, it could be more informative.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the description does not add meaning to the 'username' parameter beyond its name. No guidance on format, case sensitivity, or constraints is provided. The description fails to compensate for the lack of schema documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'Hacker News user profile'. It is specific and distinguishes from sibling tools like hn_item or hn_stories which deal with stories and items, not user profiles.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives. While it is clear that this is for user profiles, the description does not mention context, prerequisites, or exclusions. Siblings exist for stories, but no direct comparison is made.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description bears full responsibility for behavioral disclosure. It implies a read operation ('get') but does not explicitly state idempotency, required authentication, rate limits, or any side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence (13 words) with no fluff. It could benefit from additional structure for clarity, but it is efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Without an output schema and with no annotations, the description is too minimal. It does not mention what data the tool returns (e.g., company details, fields), leaving the agent with insufficient context for a 4-parameter tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds value by clarifying that company_id 'takes precedence over name', which is not in the schema. However, the other two parameters (client_id, client_secret) lack descriptions, and the schema already covers 50% of parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('get'), resource ('game company from IGDB'), and method ('by name or ID'). It effectively distinguishes from sibling tools like igdb_search_games and igdb_get_game.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., igdb_search_games for broad searches). No prerequisites (like API credentials) or context on name vs ID usage are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavioral traits. It does not mention authentication requirements, rate limits, or what 'details' entails (e.g., whether it returns parts, images, or instructions).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise (one sentence) and front-loaded. However, it could be more structured, e.g., by listing key parameters or output. It earns its place but is somewhat sparse.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple single-entity lookup tool, the description is adequate but does not explain the return value or any constraints. Despite no output schema, it could mention what details are provided. Given sibling tools, more context would help.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 50%, with only `set_num` described. The description adds no extra meaning beyond the schema ('by set number' is redundant). It does not explain `api_key` or provide format examples for the set number.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get details'), the resource ('specific LEGO set'), and the identifier ('by set number'). It distinguishes from sibling tools like `lego_search_sets` (search) and `brickset_get_set` (different data source).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like `brickset_get_set` or `lego_search_sets`. The description does not mention exclusions or preferred contexts.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided. The description only states the purpose ('get the parts list') without disclosing behavioral traits such as whether authentication (api_key) is required, rate limits, or what happens on invalid set_num. For a read operation, the description adds no extra behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence of 8 words. It is front-loaded with the verb and resource, making it easy to scan and understand quickly. No extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and a list endpoint, the description does not specify the return format, pagination, or how to handle errors. Sibling tools like 'lego_get_set' may provide more context, but the description alone is incomplete for an agent to use effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain the parameters. While 'set_num' is likely the set number and 'api_key' an authentication key, the description adds no meaning beyond the schema. For a minimal description, this is insufficient to compensate for the lack of parameter documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('get') and the resource ('parts list for a LEGO set'), which is specific. It distinguishes from sibling tools like 'lego_get_set' (set details) and 'lego_search_parts' (search parts) by focusing on a specific set's parts list.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like 'lego_search_parts' or 'lego_get_set'. Agents have to infer from the description alone, which lacks any when-to-use or when-not-to-use information.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behavioral traits like authentication requirements, token validity, or message limits, but only states the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no redundancy, front-loaded with the core action and context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Lacks context about prerequisites (where to get reply token, channel access token), error handling, and comparative guidance with sibling tools, leaving gaps for a 4-parameter tool with no output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description does not explain parameters beyond the schema; it mentions 'reply token' but does not clarify channel_access_token or message constraints, adding minimal value over the 50% schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool replies to a LINE message using a specific token from a webhook event, distinguishing it from other LINE tools like broadcast or send message.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like line_broadcast or line_send_message; the context of webhook token is implied but not explicitly contrasted with siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must convey behavioral traits. It only states the action without disclosing whether the operation is read-only, requires authentication (though workspace_gid implies it), or any side effects. This is insufficient for a mutation-prone API.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, clear sentence with no wasted words. However, it lacks structure (e.g., bullet points or separation of concerns) that could improve scannability.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description should provide more context, such as authentication requirements, behavior with no results, or pagination details. It falls short for a tool interacting with a complex API.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers 75% of parameters with descriptions (workspace_gid, archived, limit). The description adds no extra meaning beyond the schema, so it meets the baseline for high coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List projects in an Asana workspace' uses a specific verb ('List') and resource ('projects in an Asana workspace'), clearly distinguishing it from sibling tools like 'list_asana_tasks' and 'list_asana_workspaces'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as 'list_asana_tasks' or 'get_asana_task'. The description lacks explicit context for usage or exclusion.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description provides only basic behavior. Does not disclose pagination behavior, rate limits, or data format. Minimal addition beyond the tool name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Very concise at one sentence, but effectively conveys the core purpose. Could benefit from more detail without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations, no output schema, and 4 parameters, the description is too minimal. Does not cover pagination, authentication context, or expected return structure.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 75%, so baseline is 3. Description adds no parameter information beyond what the schema provides, but schema already covers most parameters adequately.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the verb 'list' and resource 'Pinterest boards', specifically for the authenticated user. Distinguishes from sibling tools like 'list_pinterest_pins'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like 'search_pinterest_pins' or 'get_pinterest_board'. No mention of prerequisites or limitations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behavioral traits like pagination (limit parameter), result ordering, or that only tenant-specific todos are returned. The description only states 'returns todos' without these details, leaving the agent unaware of important runtime behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three short sentences: purpose, use cases, requirement. No redundant information, every sentence adds value. Highly efficient and front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and 4 parameters, the description is adequate but minimal. It lacks details on pagination, filtering by assignee, and return format. For a common list tool, more context would improve agent understanding, but it provides the essentials.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (2/4 parameters lack descriptions). The description adds context for 'agent_id' (required) and 'status' (optional filter) but ignores 'assigned_to_agent_id' and 'limit'. It does not fully compensate for the schema gaps.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states that the tool returns todos for a tenant, optionally filtered by status. It provides use cases like rendering a kanban view or finding assignments, which distinguishes it from creation or update tools. However, it does not differentiate from the sibling 'list_actionable_todos', so not a perfect 5.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description suggests usage scenarios (kanban view, assignments, next work) but lacks explicit when-to-use or when-not-to-use guidance. No comparison with alternatives like 'list_actionable_todos' is provided, and prerequisites beyond 'agent_id required' are missing.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. It only states the operation without disclosing behavioral traits such as rate limits, data freshness, or whether it is a safe read operation. This is insufficient for a tool with zero annotation coverage.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    One sentence with no fluff, efficiently conveys purpose. However, it is slightly under-specified and could include more value without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a zero-parameter tool, the description covers the basic purpose. But it lacks details about what 'current' means, whether it returns multiple jackpots, and the output format. Given the absence of an output schema, more context would help.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    No parameters exist, so baseline score 4 applies. Description does not need to add parameter info, but could mention that no input is required.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states it gets current Australian lottery jackpots from The Lott, specifying verb, resource, and source. However, it does not differentiate from sibling tool 'lott_results', which may overlap in purpose.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like 'lott_results', nor any prerequisites or exclusions. The description is too minimal to inform decision-making.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description must carry behavioral context. It lacks details on authentication needs, rate limits, error handling, or response structure. Only states the conversion function.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, 10 words, efficient for core purpose. Could add optional usage note without bloat.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 5 parameters (2 optional) and no output schema, more context is needed. No mention of return format, limitations, or how to interpret results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers 100% of parameters with descriptions. The tool description adds no additional meaning beyond converting coordinates; language and types parameters are not elaborated.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Convert coordinates') and the target resource ('place name or address'), using Mapbox reverse geocoding. It distinguishes from sibling 'mapbox_geocode_forward'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like forward geocoding, directions, or static maps. No context for prerequisites or scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description only states basic action without detailing side effects, return format, rate limits, or behavior beyond generating a URL. Does not disclose that it returns a URL (not an image).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence is concise and front-loaded, but slightly under-specified for the number of parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 8 parameters, no output schema, and no annotations, the description is too minimal. Does not explain the output type (URL string) or key features like styling and size constraints.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all 8 parameters. Description adds no extra meaning beyond schema, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states verb 'Generate', resource 'static map image URL', and scope 'for a given location using Mapbox'. Distinct from sibling tools like geocoding or directions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use vs alternatives, no prerequisites or limitations mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but only states what it does. It does not disclose behavioral traits like error handling, rate limits, read-only nature, or response format, which are left to the agent to infer.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence with no unnecessary words. It is efficient but may be too minimal; still, it earns its place by being clear.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (1 parameter, simple retrieval), the description is minimally adequate. It covers the basic purpose and key parameter but lacks details on error scenarios or output, which are not provided by output schema either.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate. It adds no extra meaning beyond the schema; the parameter 'mbid' is self-explanatory from the tool name, but the description does not elaborate on its format or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'MusicBrainz release', and the identifier 'MBID'. It effectively distinguishes from sibling tools like mb_search_releases (search) and mb_get_artist (get artist).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description does not disclose behavioral traits such as rate limits, authentication requirements, error handling, or what happens if the edition is not found. The description carries the full burden but provides minimal additional context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence of 8 words, very concise. However, it could benefit from additional details without becoming overly verbose. Structure is appropriate for the simplicity of the tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (1 parameter, no output schema, no annotations), the description is minimally adequate. However, it does not explain return values, pagination, or error states, which would be helpful for completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate. It mentions ISBN but does not specify format (10/13 digit, hyphens, etc.) or provide any validation details. The parameter is minimally described.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'get', resource 'book edition', source 'Open Library', and identifier 'ISBN'. It is specific and distinguishes from sibling tools like openlibrary_get_book and openlibrary_search.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description does not disclose behavioral traits (e.g., state changes, required permissions, idempotency, side effects). It only states 'resolve' which implies mutation, but no further details.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no waste. It is concise, though lacks structured front-loading. It earns its place but could be slightly improved with brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity of the operation (resolve by ID), the description is too minimal. It does not explain what resolving entails, return values, or any prerequisites. With no output schema or annotations, more context is needed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema already documents both parameters. The description adds no extra meaning beyond the schema (e.g., no clarification on API key scope or incident ID format). Baseline is 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (resolve), the resource (PagerDuty incident), and the identifier (by ID). It effectively differentiates from sibling tools like acknowledge, create, get, and list.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., acknowledge_incident) or any prerequisites. The description lacks any usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full responsibility for behavioral disclosure. It omits any details about idempotency, side effects, rate limits, error behavior, or authorization requirements beyond requiring an api_key. The description only names the actions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence that efficiently conveys the tool's purpose. There is no extraneous text, though it could be slightly improved by grouping actions or adding structure.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and a multi-action tool, the description lacks details about return values or how results differ per action. It is too minimal to be fully informative for an agent selecting and invoking the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the baseline is 3. The description does not add any meaning beyond the schema; it restates the action options in natural language but provides no additional context on how to use parameters like collection_id or workspace_id.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool interacts with the Postman API and lists the specific actions: list and retrieve collections, list environments, and list monitors, which exactly match the action enum. Since no sibling tools share the Postman domain, differentiation is inherent.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, no conditions for selecting specific actions, and no prerequisite information (e.g., obtaining an API key). It merely states capabilities without contextual usage advice.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behavioral details like rate limits, error handling (e.g., what if template ID does not exist), or authentication requirements beyond the parameter schema. It provides only the basic operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with minimal words. It is front-loaded and to the point, though it could benefit from slightly more context without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity of the tool (2 params, no output schema), the description is incomplete. It should hint at the response structure or typical usage context (e.g., 'Returns name, subject, etc.').

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description does not add any meaning beyond the schema; it only mentions 'by ID' which is already captured by the template_id parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it retrieves a single Postmark email template by ID. The verb 'get' combined with 'by ID' differentiates it from sibling tools like 'postmark_list_templates' which retrieves multiple templates.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as 'postmark_list_templates' for listing all templates. The agent may not know which tool to choose for retrieving a specific template.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; the description simply restates the action without detailing behavioral traits like authentication requirements, rate limits, or side effects (state change). Insufficient for a write operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise: one sentence with no wasted words. Front-loaded and efficiently communicates the core purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema and no annotations; description lacks information about return values, success/failure indicators, or the effect on user's subscriptions. Incomplete for a tool with no output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is only 33% (action param described). Description does not clarify 'access_token' or 'sr' (subreddit name) beyond the parameter names. No added value over schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the tool subscribes or unsubscribes to a Reddit subreddit, using a specific verb and resource, and is distinct from sibling tools like reddit_comment, reddit_post, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., browsing or posting). No when-not or exclusions provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description bears full responsibility for behavioral disclosure. It only states the purpose but does not mention that it reads data, requires an API key (listed in schema), supports pagination via limit and cursor, or that results may be filtered by type. These omissions reduce transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence that immediately communicates the tool's primary action and scope. No extraneous words or information, achieving high conciseness with strong front-loading.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite having 4 parameters and no output schema or annotations, the description omits details about pagination, filtering, authentication, and return format. Given the complexity, it fails to provide sufficient guidance for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 75% (3 of 4 params described). The tool description adds no additional meaning for any parameter, and the undocumented 'cursor' parameter is not clarified. The description does not compensate for the missing schema detail.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List' and the resource 'Render services', with examples of service types like 'web services, static sites, cron jobs, etc.'. This distinguishes it from sibling tools like render_get_service (single service) and render_list_deploys (deploys), making purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as render_get_service for specific services. There is no mention of use cases, prerequisites, or exclusions, leaving the agent to infer context from other tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the full burden. It only states the action (list) but omits behavioral details such as pagination, rate limits, authentication method, or whether the API key is user-specific. The read-only nature is implied but not explicit.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence (7 words) with no redundant information. It is front-loaded and efficiently conveys the tool's purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list operation with well-documented parameters, the description is minimally viable. However, it lacks information about the output format, error handling, or prerequisites (e.g., source_id existence), which would be helpful given no output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, with both parameters ('api_key', 'source_id') already described in the schema. The description adds no extra meaning beyond the parameter names, so it meets the baseline of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (List), resource (destinations), and scope (connected to a Segment source). It is specific and unambiguous, but does not explicitly differentiate it from sibling tools like segment_list_sources or segment_get_source, preventing a top score.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, nor any prerequisites or context. For example, it does not mention that this tool requires a source_id obtained from segment_list_sources first.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description needs to disclose behavioral traits. It only says 'Add or update,' but does not explain that it is an upsert operation, what happens to existing fields, potential side effects (e.g., list membership changes), or any mutation details. The minimal description leaves the agent uninformed about important behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, direct sentence with no extraneous words. It is efficient, but could be slightly improved by clarifying the upsert nature without adding length.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 6 parameters (2 required, 4 optional) and no output schema, the description is insufficiently complete. It does not explain the upsert semantics, the optional parameters (like list_ids, phone_number), or what the tool returns. More context is needed for an agent to use it effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, with each parameter described in the input schema. The description adds no extra meaning beyond what is already in the schema. Therefore, it merely meets the baseline expectation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Add or update a marketing contact in SendGrid.' It uses specific verbs ('add or update') and identifies the resource ('marketing contact'), distinguishing it from sibling tools like sendgrid_list_contacts (for listing) and sendgrid_send_email (for sending).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention that it performs an upsert (create or update), nor does it suggest when to use sendgrid_list_contacts for reading contacts or sendgrid_send_email for sending. No context about prerequisites or exclusions is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description provides minimal behavioral information beyond listing contacts; does not address pagination, rate limits, or handling of API keys. Annotations are absent, leaving the description responsible for such details.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence that efficiently conveys the core functionality. Could be slightly expanded without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of annotations and output schema, the description does not provide enough context about expected behavior (e.g., pagination, filtering, response format) for an agent to fully understand the tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% for the api_key parameter, and the description adds no additional meaning beyond what the schema already provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the verb 'List' and the resource 'all marketing contacts' in SendGrid, clearly distinguishing it from sibling tools like sendgrid_add_contact.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus other SendGrid tools (e.g., sendgrid_add_contact, sendgrid_search_contacts).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description bears full responsibility for disclosing behavioral traits. It only states 'Get,' implying a read operation, but provides no details on side effects, authentication requirements, or output characteristics. It is minimally adequate but not transparent.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that front-loads the core action. It is efficient and avoids verbosity, though it could benefit from slightly more detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity and lack of an output schema, the description should at least hint at what information is returned. It does not, leaving a gap in completeness. However, for a straightforward get operation, it is borderline adequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema includes three parameters with 0% description coverage, and the description adds no meaning beyond the schema. Parameter names (shop_domain, api_key, access_token) are somewhat self-explanatory, but the description fails to clarify their roles, requiredness, or relationships.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get Shopify store information' clearly states the action (Get) and the resource (Shopify store information). It is specific enough to distinguish from sibling tools like shopify_products or shopify_orders, which target different entities.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description lacks any guidance on when to use this tool versus alternatives. It does not mention context, prerequisites, or exclusions, leaving the agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description fails to disclose behavioral traits such as read-only nature, rate limits, or return format. The description only states the purpose without additional transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence. It is concise and front-loaded, though it could briefly mention what 'state' includes (e.g., week, season type).

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a parameterless tool, the description is adequate but lacks detail about the return value. The agent may need to experiment to understand the output structure, given no output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With zero parameters, the baseline is 4. The description adds no parameter info, but no further explanation is needed as the input schema is already complete.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool returns the current NFL state from Sleeper, using a specific verb and resource. It distinguishes from sibling tools like sleeper_league or sleeper_players by focusing on 'state' rather than leagues or player data.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., sleeper_league for league details). The agent must infer the context from the name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description does not disclose any behavioral aspects beyond basic counting. Does not mention case sensitivity default or edge cases like overlapping matches.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple, but without output schema or additional details, the description should explain return values (e.g., returns list of strings). It does not, leaving the agent uncertain about the output format. Edge cases are not addressed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, requiring the description to add meaning. However, the description adds no detail about the 'text' parameter beyond its name in the schema. It does not specify expected format, encoding, or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (extract) and resource (all URLs from a text). It effectively distinguishes from sibling tools like text_extract_emails and text_extract_phone_numbers which operate on different patterns.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    While the purpose implies usage for URL extraction, no explicit guidance is provided on when to use this tool versus alternatives. There is no mention of when not to use it or of related tools like text_extract_emails.

    The description provides no guidance on when to use this tool versus alternatives such as tmdb_search_movies or tmdb_now_playing. It lacks context on prerequisites or scenarios where this tool is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must fully disclose behavioral traits, but it only states the basic function. It does not mention authentication requirements beyond the api_key parameter, rate limits, output format, or any potential side effects. For a tool that makes API calls, this is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence with no wasted words. It is front-loaded with the core action and resource. However, it could benefit from additional detail without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 8 parameters and no output schema, the description should provide more context about usage and expected return values. It fails to clarify what the completion output looks like or how to handle the response. The description is too brief for a tool of this complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description adds no additional meaning beyond what is already in the input schema. It does not explain the role of required parameters like api_key or prompt, but the schema already provides those details.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (run), the resource (text completion), and the scope (any Together AI model). It effectively distinguishes itself from sibling tools like togetherai_chat_completion by specifying 'text completion' rather than 'chat completion'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like togetherai_chat_completion, togetherai_create_embedding, or togetherai_list_models. The description lacks context for selecting the appropriate tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits, but it only states the basic action. There is no mention of permissions, rate limits, input size limits, or whether the operation is read-only or creates side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence of 10 words, efficient and front-loaded with the purpose. However, it could be slightly more detailed without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and annotations, the description should compensate with context about return values, input constraints, or batch support. It does not, leaving significant gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with parameter descriptions. The tool description adds no extra meaning beyond what the schema already provides, so baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Create'), resource ('text embeddings'), and provider ('Together AI embedding model'). It is specific and distinguishes from sibling embedding tools like openai_create_embedding.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., other embedding models), nor are there any exclusions or use-case recommendations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description omits behavioral details such as whether the call is synchronous, what is returned, or any cost or rate limit implications. The word 'Initiate' hints at asynchronous behavior but is not explicit.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, concise sentence that is front-loaded and contains no extraneous words. Could include more detail without becoming verbose, but current form is efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema is provided, and the description fails to explain the return value or how the call progresses after initiation. For a tool that makes a phone call, this is insufficient context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 67%, with descriptions for 4 of 6 parameters. The description adds no additional meaning beyond the schema, so it meets the baseline but does not enhance understanding.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Initiate an outbound phone call') and the service ('via Twilio'), effectively distinguishing it from sibling tools like twilio_send_sms or twilio_list_calls.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. The agent is left to infer context solely from the name and schema.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It only indicates mutation (edit) and lists editable fields/statuses, but omits permissions, side effects, or whether it returns the updated idea.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    One sentence with inline status values is concise, though slightly longer due to listing all enum values. No front-loading issues.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Missing intent: does not mention idea_id requirement (in schema), whether multiple fields can be updated simultaneously, or the return value. For a 5-parameter update tool with no output schema, the description is incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%, so description partially compensates by listing editable fields and status enum values. However, it does not explain parameter purposes beyond their names, and redundant 'agent_id required'.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it edits an idea's title, description, or status, distinguishing it from siblings like create_idea, list_ideas, and vote_on_idea.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like create_idea or promote_idea_to_todo. Does not specify conditions or prerequisites beyond requiring agent_id.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and description lacks disclosure of read-only nature, authentication requirements, rate limits, pagination, or result limits. The vague 'matching a pattern' does not specify return behavior or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with no redundancy. Efficiently conveys the core action and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema and description does not mention return value format (e.g., list of key names, count, pagination). Lacks information about authentication parameters. Insufficient for an agent to fully understand tool behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 25% (pattern parameter has description). Description adds no explanation for api_key, email, or db_id, leaving the agent to infer their roles. Does not compensate for the sparse schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the verb 'list' and resource 'keys in an Upstash Redis database' with optional pattern matching. It effectively distinguishes from sibling Upstash Redis tools like get, set, del which handle individual keys.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus other Upstash Redis tools or alternatives. Does not mention when not to use it or provide context for pattern selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but only says 'Get the HTML report'. It omits important behavioral details like whether the report is generated synchronously, if it requires a successful run, or the format of the output (text, file, etc.).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence that is concise and directly states the tool's purpose without extraneous information. However, it could be slightly more informative without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of multiple report format siblings and no annotations, this description is too minimal. It does not explain output format, prerequisites, or error conditions, leaving gaps for an agent to infer.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with run_id described as 'The run id returned by uxpass_run'. The description adds no further meaning beyond what the schema already provides, earning the baseline score.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the specific resource 'HTML report for a UXPass run'. It effectively distinguishes from sibling tools like uxpass_report_json and uxpass_report_md by specifying the output format.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., HTML vs JSON vs Markdown reports). No context about prerequisites such as needing a completed run.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description does not disclose any behavioral traits beyond basic listing. No annotations are provided. Important details like pagination, order, filtering, rate limits, or authentication requirements are omitted.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with no output schema and no annotations, the description is too minimal. It does not explain return format, pagination, or error scenarios, leaving the agent under-informed for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has three parameters (projectId, limit, api_key) with 0% schema description coverage. The description only implies the projectId role ('for a project'). No explanations of limit or api_key are provided.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states 'List Vercel deployments for a project.' It uses a clear verb-resource pair and distinguishes from sibling tools like vercel_create_deployment, vercel_get_deployment, and vercel_list_projects.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as vercel_get_deployment for a single deployment or vercel_create_deployment for creating one. The description lacks context about the tool's role in the workflow.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 3 parameters, no output schema, and no annotations, the description is too sparse. It omits details like the expected range for 'days', where to obtain 'api_key', and what the response structure looks like. The phrase 'Australian location' is ambiguous.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 33% (only 'location_id' has a description). The description does not add meaning for 'days' or 'api_key' parameters, failing to compensate for the low coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly specifies the verb ('Get'), resource ('weather forecast'), source ('WillyWeather'), and geographic scope ('Australian location'). This distinguishes it from generic weather forecast tools and other WillyWeather tools like willyweather_surf and willyweather_tide.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite having 4 parameters and no output schema, the description omits details about the returned data structure (e.g., playlist titles, IDs), leaving the agent underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description adds no meaning to the parameters (api_key, channel_id, max_results, page_token) beyond what is in the schema, failing to compensate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List' and the resource 'playlists' with a scope 'belonging to a YouTube channel', effectively distinguishing it from sibling tools like youtube_get_video or youtube_search.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must fully disclose behavior. It omits important details such as side effects (none expected), authentication requirements (api_key needed but not highlighted), rate limits, error handling, or response format. This lack of transparency could lead to unexpected agent behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise with two sentences. The first sentence directly states the core functionality, and the second adds context. No unnecessary words or repetition, making it efficient for agents to parse.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 10 parameters and no output schema or annotations, the description is insufficient. It fails to explain how parameters interact, required fields beyond api_key, expected output, or error conditions. An agent would need additional context to use this tool reliably.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema already describes 60% of parameters (e.g., model, prompt, messages, system, max_tokens). The description adds no extra semantic value beyond what the schema provides, so it meets the baseline for moderate coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Send a message') and the target resource ('Anthropic Messages API (Claude models)'). It identifies the tool as a means to call Claude programmatically, which differentiates it from sibling LLM tools like OpenAI or Groq, though not explicitly naming alternatives.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description gives a use case ('agents that need to call Claude programmatically or compare model outputs'), implying when to use it. However, it does not mention when not to use it or explicitly compare to sibling LLM tools, leaving room for ambiguous selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full responsibility. It fails to disclose behavioral traits such as pagination, ordering, what 'recent' means, or whether results are truncated. The schema hints at cursors but the description does not integrate or clarify this.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 5 parameters, no output schema, and no annotations, the description is too sparse. It lacks details on response format, pagination behavior, and what constitutes 'recent', leaving the agent with insufficient context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema already documents parameters. The description adds no extra meaning beyond the schema; the term 'recent' is ambiguous and not reflected in parameters. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'list' and the resource 'recent AssemblyAI transcripts for the account', which is specific and distinguishes it from sibling tools like assemblyai_get_transcript (single) and assemblyai_transcribe (create).

    The description implies usage for tracking a parcel but provides no explicit guidance on when to use this tool versus alternatives or any exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full responsibility for behavioral traits. However, it only states the basic function and does not disclose important behaviors like whether the results are paginated, if it is read-only, or any potential side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that directly states the tool's purpose. While it could be slightly more informative without becoming verbose, it currently has no wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple nature of the tool (listing jobs) and no output schema, the description is minimally adequate but lacks details about the return format, prerequisites like the workflow must be valid, or any ordering/filtering of jobs.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% coverage, with descriptions for both parameters (api_key and workflow_id). The description adds no additional semantic information beyond the schema, but since schema coverage is high, the baseline of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List jobs in a CircleCI workflow' clearly states the verb (list), resource (jobs), and context (CircleCI workflow), distinguishing it from sibling tools like circleci_list_pipelines, circleci_list_workflows, and circleci_trigger_pipeline.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as when to use circleci_get_workflow for workflow details or circleci_list_pipelines for pipeline overview. No prerequisites or context for usage are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. The description does not disclose pagination, rate limits, or that the operation is read-only. It only states the basic function, leaving behavioral traits unspecified.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Very concise single sentence, but front-loaded and to the point. No wasted words, though could be slightly more structured.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 5 parameters and no output schema or annotations, the description is adequate but lacks context on pagination, return format, or authentication requirements. It covers the basics.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with detailed parameter descriptions. The description adds minimal extra meaning beyond restating the branch filter, so baseline of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('list') and resource ('CircleCI pipelines'), and distinguishes from sibling tools by mentioning optional branch filtering. It tells exactly what the tool does.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like circleci_get_pipeline or circleci_list_workflows. It does not specify prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations. The description does not disclose supported units, rounding behavior, or error handling. Users are left to guess valid inputs for 'from' and 'to', which is a significant gap for a conversion tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence, very concise. However, it could include a list of supported units without losing conciseness. Still appropriate for a simple tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with no output schema and 0% parameter descriptions, the description is insufficient. It does not specify what speed units are accepted, making it incomplete for reliable agent invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage. The description adds only the concept of speed but does not specify valid unit strings or expected formats. It fails to compensate for the schema gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Convert between speed units' clearly states the tool's function with a specific verb and resource. It distinguishes itself from sibling convert tools (e.g., convert_weight, convert_length) by specifying speed.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. While the name implies it's for speed, explicit context or exclusions (e.g., not for other units) is missing. Adequate but lacks proactive differentiation.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It only states the source and sorting order, leaving out details like return format, pagination behavior, or any rate limits. This is insufficient for a tool with multiple parameters.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. It is concise but lacks structured details that would improve usability.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 3 parameters and no output schema or annotations, the description is too brief. It does not cover output expectations, pagination, or default behavior, leaving significant gaps for the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description does not explain the meaning of vs_currency, per_page, or page. Users must infer parameter purposes, which is inadequate for a tool with three optional parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it retrieves top cryptocurrencies by market cap from CoinGecko. It uses a specific verb and resource, distinguishing it from sibling tools like crypto_search (search) and crypto_price (price).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for listing top coins by market cap but provides no explicit guidance on when to use this over other crypto tools, nor does it mention any prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, description should disclose behavioral traits; it only states basic purpose, missing details on pagination, auth needs (beyond schema), or output format.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description only vaguely hints at the timezone parameter ('optionally in a specific timezone') without any details on the format parameter or acceptable values.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses the specific verb 'Get' and resource 'current date and time', clearly distinguishing it from sibling tools like datetime_convert_timezone or datetime_format_date.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. For example, it doesn't mention that for converting a specific date/time to another timezone, one should use datetime_convert_timezone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description bears full responsibility for behavioral disclosure. It only states 'neural translation engine' without mentioning rate limits, authentication requirements (auth_key is required but not highlighted), or the array input limit of 50 texts. The tool's safe/mutating behavior is not indicated.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% (access_token documented), so baseline is 3. The description adds no further meaning to the parameter beyond what the schema provides. It does not explain how the token is used or alternative ways to provide it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'authenticated TikTok user profile', and enumerates sample return fields (follower count, video count). This distinguishes it from sibling tools like get_tiktok_video and list_tiktok_videos, which focus on videos.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, nor are prerequisites like needing an access_token mentioned. The description does not address when not to use it or suggest other tools for related tasks.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. Only mentions speed; lacks details on streaming, context length, rate limits, or authorization requirements beyond the schema.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences, front-loaded with action verb and resource. Every word adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema; description fails to mention return format (e.g., text completion). For a complex tool with 9 parameters, more context (like non-streaming behavior) is needed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers all 9 parameters with descriptions. Description adds no extra meaning beyond listing model names, which the schema already does via default and examples.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clear verb+resource: 'Run a fast LLM inference with Groq'. Lists supported models (Llama 3, Mixtral, Gemma), distinguishing it from other LLM tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this vs. other chat completion tools (e.g., openai_chat_completion, anthropic_create_message). Mentions speed but no explicit comparison or exclusion criteria.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description does not disclose any behavioral traits such as authentication requirements (beyond the schema), rate limits, or output format. The description is too sparse to inform the agent of potential side effects or constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that efficiently conveys the tool's purpose with no unnecessary words or repetition.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite the tool's simplicity, the description fails to mention what the output contains (e.g., model IDs, names) or any limitations. Without an output schema, the agent lacks essential context for interpreting results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers 100% of parameters and describes api_key fully. The description adds no additional meaning to the parameters, so it meets the baseline but does not exceed it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (list) and the resource (all models available on Groq), which distinguishes it from similar tools for other providers like OpenAI or Anthropic.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus other list_models tools (e.g., anthropic_list_models, openai_list_models). The description does not help an agent choose between them.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden. It only says 'get details' without disclosing read-only nature, authentication requirements (though api_key param exists), rate limits, or error responses. Minimal behavioral information.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence of 8 words that is front-loaded and efficient. Every word earns its place with no repetition or fluff.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema exists, but the description fails to hint at what 'details' are returned. Combined with missing behavioral transparency and usage guidance, the tool is inadequately documented for a new user.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and each parameter has a description ('Gumroad access token', 'Product ID (permalink)'). The description adds no additional meaning beyond the schema, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'get details' for the resource 'a single Gumroad product' identified 'by ID'. This distinguishes it from sibling tools like gumroad_list_products (list) and gumroad_get_sale (sale details).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. The description does not mention prerequisites, limitations, or comparison with other Gumroad tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. It does not disclose output format, pagination, error states, or any side effects. Merely states 'Get details' with no behavioral specifics.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no wasted words. Purpose is front-loaded. Efficiently communicates core action.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite clear purpose, the description lacks output format, constraints, or any additional context needed for a complete understanding. With no output schema and no annotations, the agent is left guessing what 'details' means.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers 100% of parameters with descriptions. The tool description adds no new meaning beyond what the schema already provides. Baseline of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get details'), the resource ('a single Gumroad sale'), and the identifier ('by ID'). It distinguishes from siblings like gumroad_list_sales which lists multiple sales.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use vs alternatives. No mention of prerequisites, exclusions, or comparison to gumroad_list_sales. Agent must infer use case from description alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Without annotations, the description should fully disclose behavioral traits. It mentions returns video_id for polling and that test parameter avoids quota, but omits details like processing time, cost, or typical success rates.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences cover the core action and return value. No unnecessary information, well front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 10 parameters and no output schema, the description is somewhat complete but lacks details on post-creation behavior, default value implications, and error states.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with well-described parameters. The description adds minimal value beyond the schema, not providing additional nuance or usage tips.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the tool creates an AI avatar video with HeyGen, clearly distinguishing it from sibling tools like heygen_get_video_status. However, it does not explicitly contrast with other tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like heygen_list_avatars or heygen_get_video_status. The description implies polling for completion but lacks explicit when-to-use or when-not-to-use instructions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It only states the basic action without disclosing how the check works (e.g., hashing, API details, rate limits).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that front-loads the action, but it sacrifices necessary detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description does not explain what the tool returns (e.g., boolean, breach details), leaving the agent uninformed about the response.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning beyond the parameter name 'password', omitting format or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'check' and resource 'password', clearly distinguishing from siblings like hibp_all_breaches and hibp_check_account which check different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for checking a single password but does not provide explicit guidance on when to use this tool versus alternatives like hibp_check_account for email checks.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description must carry full burden. Fails to disclose return format, permissions needed, or any side effects. Simply states it lists styles without elaboration.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence that is direct and to the point. No wasted words, easily scannable.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Missing details about what the output looks like (list of strings or objects) and how to use the fetched styles. Incomplete for a tool with no output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and description adds no extra meaning beyond the schema's own description of 'api_key'. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clear verb ('List') and resource ('available Soul Styles'). Distinguishes from sibling tools like higgsfield_generate_image by focusing on retrieval of styles rather than generation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus other Higgsfield tools. Misses opportunity to mention that this should be called before generation to select a style.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description gives no behavioral context beyond the bare action. It does not disclose authentication requirements (though parameters imply them), rate limits, pagination, or what happens if no results are found. The description carries the full burden but fails to deliver.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no wasted words. It immediately conveys the purpose. Every word earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters and no output schema or annotations, the description is too brief. It lacks information about return format, result structure, and usage constraints (e.g., authentication). For a search tool, this is inadequate for an agent to use effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema already documents all parameters. The description adds no extra meaning beyond stating that it searches by name. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches the IGDB games database by name. The verb 'search' and resource 'IGDB games database' are specific and distinct from siblings like igdb_get_game or igdb_list_genres.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. For example, it doesn't mention that igdb_get_game should be used for fetching details of a specific game, or that this tool is for name-based search only.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description bears full burden. It states the action (remove) and scoping (caller's API key), but does not disclose whether the operation is irreversible, if it has side effects, or what happens on failure.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two efficient sentences: first states purpose, second adds scoping. No wasted words; front-loaded with key information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Missing information about error handling, success/failure response, and what happens when platform or credential is not found. Since no output schema exists, the description should compensate but fails to do so.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the description adds no extra parameter meaning beyond what the schema already provides. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'Remove a platform credential from the UnClick Keychain', using a specific verb and resource. It distinguishes from sibling tools like keychain_connect (adding) and keychain_list_platforms (listing).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., keychain_secure_connect for secure removal). No mention of prerequisites or scenarios where disconnection is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It mentions 'exposes LegalPass guardrails and the safe run envelope', suggesting safety but not detailing side effects, return value, or whether it mutates state. The behavioral disclosure is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, no fluff. The first sentence states action and targets, the second clarifies scope and mentions guardrails. Every word earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite lacking an output schema, the description does not describe what a 'plan' looks like or how it relates to other LegalPass tools (e.g., legalpass_verdict). The mention of 'guardrails and safe run envelope' is too vague. Context is incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 75%, so baseline is 3. The description adds little beyond what the schema already provides: it lists target types but does not enrich the meaning of profile or jurisdictions. No extra semantic value is added.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool plans a LegalPass issue-spotting run against three target types (URL, contract upload, repo). It distinguishes from full execution by noting it is scaffold-only. However, it does not explain what LegalPass or issue-spotting is, assuming familiarity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description says 'scaffold-only' and contrasts with full 12-hat execution in a later engine chip, implying this is for planning. But it does not explicitly state when not to use it or name alternatives like legalpass_verdict. The guidance is implied rather than explicit.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for disclosing behavior. It implies read-only but does not mention safety, authentication requirements, rate limits, or response structure.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no extraneous words. It efficiently conveys the tool's purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is minimally adequate for a simple lookup tool with one parameter. However, since there is no output schema, it would benefit from mentioning what details are returned (e.g., name, status, rounds).

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single required parameter 'tournament_id' has no description in the input schema (0% coverage). The description adds no additional meaning, leaving the agent to infer its format from the name alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get details for a Lichess tournament.' clearly states the action (get) and resource (tournament details), distinguishing it from sibling tools like lichess_user or lichess_puzzle_daily.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, or any prerequisites. The description is purely a statement of purpose without usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description should disclose side effects or constraints. It only states a send action, without noting that a message is posted to a user's line chat, that it may be subject to rate limits, or what happens on failure. The description does not convey that this is a destructive action (sending a message).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single 10-word sentence that instantly conveys the tool's core function. It uses active voice and places the verb first, making it efficient and easy to scan.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has 4 required parameters and no output schema, yet the description provides only a one-line summary. It omits important context such as return behavior, error states, prerequisites for the Flex Message format, and any limitations. Given the lack of annotations, this is insufficient for an agent to reliably invoke the tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has descriptions for alt_text and contents only. The description does not add meaning for channel_access_token or to, which remain unannotated in schema. It does not specify that 'to' should be a user or group ID. The description adds the general context of 'user or group', but does not map to specific parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the action 'Send', the resource 'rich Flex Message', and the recipient scope 'to a LINE user or group'. This clearly distinguishes the tool from its similar sibling 'line_send_message' which likely sends plain text.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus the sibling tool 'line_send_message'. It does not mention prerequisites, such as having a valid Flex Message structure, or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and description fails to disclose behavioral traits like pagination, rate limits, or authentication details beyond what's in the schema. Just 'list boards' – insufficient for a tool with no annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no wasted words. Efficiently conveys the core purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description should provide more context about behavior, usage boundaries, and results. It is too minimal for a listing tool with many siblings.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers parameters 100% with descriptions, so description adds minimal value. Baseline 3 is appropriate as it doesn't elaborate further on parameter usage or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'List boards in a Monday.com account' – specific verb (list), resource (boards), and scope (in an account). Distinguishes from sibling tools like get_monday_board or search_monday_items.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives (e.g., get_monday_board for a specific board). Lacks context for agent to make informed choices among many Monday.com sibling tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description bears full responsibility for behavioral disclosure. It does not mention pagination, rate limits, error handling, or idempotency. The description is minimal and omits important behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence (10 words), very concise and front-loaded. It efficiently conveys the core purpose, though slightly more detail could be added without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool that lists campaigns with filters, the description provides a minimal but functional overview. However, it lacks details on pagination, output format, or error handling, which are important for a complete understanding. No output schema exists, so these gaps are notable.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema already documents all parameters. The description adds that filtering is optional, which aligns with the status and list_id parameters. This adds marginal value beyond the schema, meeting the baseline of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (List) and resource (Mailchimp email campaigns), and mentions optional filtering by status or audience. This differentiates it from sibling tools like mailchimp_create_campaign or mailchimp_get_campaign.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool vs alternatives, no prerequisites, and no exclusions. It only implies that filtering is optional, but lacks explicit context.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description partially defines the output by mentioning 'categories and levels,' but misses other likely fields (e.g., description, release date). It does not differentiate from sibling tools like speedrun_search_games. Moderately complete for a simple retrieval tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, and the description adds only the phrase 'including categories and levels,' which hints at response content but does not add new meaning to the parameter beyond what the schema already provides. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get details of a game on Speedrun.com including categories and levels.' It uses a specific verb and resource, and the purpose is distinct from sibling tools like speedrun_search_games or speedrun_get_leaderboard.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden. It lacks key behavioral details: the need for an API key (api_key is required but not mentioned), potential input/output format constraints, rate limits, or whether the tool is destructive (it's likely read-only, but not stated). The description is insufficient for an agent to understand side effects or requirements.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence that immediately conveys the tool's purpose. It is appropriately concise, though it could include a bit more detail without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters, no output schema, and no annotations, the description is far too minimal. It does not explain the return value, required authentication, or any constraints on input images. An agent would need additional context to use the tool reliably.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 75% (3 of 4 parameters have descriptions), but the tool description adds no extra meaning. The api_key parameter lacks a schema description and the description does not explain it. The width and engine_id parameters are partially documented in schema, but the description provides no clarification on valid ranges or available engines.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly specifies the action ('Upscale'), the resource ('an image'), and the technology ('Stability AI ESRGAN'). It effectively distinguishes from sibling tools like stability_text_to_image (text-to-image) and stability_image_to_image (image-to-image), which serve different purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies when to use (when you want to enlarge an image), but it does not provide explicit guidance on when not to use it, nor does it mention alternatives among the stability tools. No prerequisites or limitations are stated.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits but only states 'Override', lacking details on permissions, idempotency, side effects, or response behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that directly conveys the core action with no extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 4 parameters, no output schema, and no annotations, the description lacks important context such as expected states, return values, or operational requirements.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, and the description adds minimal value beyond the schema by noting 'optional notes' and the override action, but does not enhance understanding of run_id or item_id.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Override' and specific resources 'verdict and optional notes for a single check item in a TestPass run', distinguishing it from sibling tools like testpass_run or testpass_status.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool vs alternatives, such as prerequisites (e.g., run must exist) or context for using it over other testpass actions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description only says 'Get the JSON report.' It does not disclose behavioral traits such as whether the operation is read-only, error handling, or requirements like run must exist. With no annotations, the description carries full burden but adds minimal context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no wasted words. It is appropriately sized for a simple retrieval tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given low complexity (1 param, no output schema), the description is minimal. It does not specify that the run must exist or mention any prerequisites. With no annotations, the agent lacks complete context for correct usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a single parameter 'run_id' described. The description does not add meaning beyond the schema (e.g., source or format of run_id). Baseline 3 is appropriate for full schema documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get the JSON report for a TestPass run,' specifying the verb, resource, and format. It distinguishes from sibling tools like testpass_report_html and testpass_report_md by explicitly mentioning 'JSON'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. Siblings exist for HTML and Markdown reports, but the description does not mention them or provide selection criteria.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden but only states the basic action. It fails to disclose key behavioral traits such as whether the report requires a completed run, error handling, or read-only nature.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no waste. While it is concise, it could add more context without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple report retrieval with one parameter and no output schema, the description is minimally adequate. It specifies the output format (Markdown) but lacks details on prerequisites, error conditions, or behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers 100% of the single parameter (run_id) with a clear description. The tool description adds no additional meaning beyond what the schema provides, meeting the baseline.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Get' and the specific resource 'Markdown report for a TestPass run', distinguishing it from sibling tools like testpass_report_html and testpass_report_json.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description offers no guidance on when to use this tool versus alternatives (e.g., HTML or JSON reports), nor does it mention prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits like pagination, rate limits, authentication needs beyond the schema, or what happens on invalid org. The agent is left guessing about response structure and errors.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no wasted words. It is front-loaded with the key action and scope.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple listing tool, the description lacks context about the response format (e.g., database names, IDs, or details). No output schema is provided, so the description should hint at return values. It does not.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for api_key and org. The description adds no additional meaning beyond the schema, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'List all databases in a Turso organization,' specifying verb (List), resource (databases), and scope (organization). It distinguishes from siblings like turso_create_database (creates) and turso_get_database (single database).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as when to use turso_get_database for a specific database or turso_list_groups for groups. No when-not or contextual advice is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden for behavioral transparency. It only states 'get' without revealing any behavioral traits such as authentication requirements (though account_sid and auth_token appear in schema), rate limits, or error cases. This is insufficient for a tool with no annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with no fluff. However, it could be slightly expanded to include brief param context without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description does not mention the output structure, error handling, or any prerequisites beyond the required params. Since there is no output schema, the agent lacks understanding of what the tool returns, making it incomplete for a read operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds minimal value beyond schema field names, only clarifying that message_sid is the identifier. It does not explain account_sid or auth_token, which are critical for authentication. With schema description coverage at 0%, the description fails to compensate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'a single Twilio message', and the method 'by SID'. This effectively distinguishes it from sibling tools like twilio_list_messages which list multiple messages.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit when-to-use or when-not-to-use guidance is provided. The agent can infer that this tool is for retrieving a specific message by SID, but no alternatives or exclusions are mentioned, leaving the decision implicit.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description does not disclose that this is a write operation that initiates a one-time password send, requiring user confirmation via a separate verification tool. With no annotations, it should mention side effects, authentication requirements, or that it does not finalize verification itself.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence of 12 words that front-loads the core purpose. It is efficient with no redundant or unnecessary information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description lacks information about what the tool returns (e.g., a verification status or success indicator) since there is no output schema. It also does not mention that the tool creates a verification attempt or that the user must check the code using twilio_check_verify.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 60% (3 of 5 parameters have descriptions). The description adds no additional meaning for account_sid and auth_token, which are left undocumented in both schema and description. For the other parameters, the schema already provides sufficient description.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it sends a verification code via Twilio Verify and lists supported channels (SMS, call, email, WhatsApp). This distinguishes it from sibling tools like twilio_send_sms which sends an SMS directly, and twilio_check_verify for checking verification codes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like twilio_send_sms or twilio_check_verify. It does not mention prerequisites such as having a Twilio Verify Service SID, nor does it specify that a subsequent verification step is needed.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the burden. It does not disclose authentication requirements (client_id and client_secret in schema but unexplained), what happens if the stream is offline, or any rate limits. Only the basic action is stated.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is one short sentence with no redundant words. However, it is too brief given the parameter count and missing annotations. Conciseness alone does not compensate for insufficient detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has 3 parameters, no output schema, and no annotations. The description does not explain authentication, response format, or error cases. It is incomplete for an agent to reliably invoke this tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%. The description only implicitly covers user_login by mentioning 'by user login'. It does not explain the purpose or format of client_id and client_secret, leaving the agent to guess their importance.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (Get), resource (specific Twitch stream), and qualifier (by user login). It distinguishes itself from sibling tools like twitch_search_streams (which returns multiple streams) and twitch_get_clips (which returns clips).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when you have a user login, but it does not explicitly state when to use this tool over alternatives (e.g., twitch_search_streams for search). No exclusions or context are provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It fails to disclose key behaviors like whether it returns nil for missing keys, idempotency, or error conditions. Only the basic operation is stated.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no fluff. It efficiently communicates the core action, though more context about parameters could be included without sacrificing brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers the basic purpose but omits important behavioral details like missing key handling and authentication context (though parameters handle the latter). It is minimally complete for a simple get operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, and the description does not add any meaning beyond the parameter names and types already documented in the schema. The baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get'), the resource ('the value of a key'), and the scope ('from an Upstash Redis database'). It distinguishes from siblings like upstash_redis_set and upstash_redis_del by focusing on retrieval.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, such as upstash_redis_list_keys for enumeration or other Redis operations. No context on prerequisites or excluded scenarios provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It only states the function without disclosing authentication needs (api_key parameter implies this but not stated), error states (e.g., if transcript not completed), or any side effects. Minimal behavioral transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no wasted words. However, it is almost too brief; a bit more detail could improve without harming conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description inadequately covers the tool's behavior. It doesn't describe the return format (list of paragraphs?), prerequisites (transcript must be completed), or error handling. Incomplete for a 2-parameter tool without structured support.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description adds no additional meaning beyond the schema: it does not explain that api_key is a authentication token or what transcript_id represents (though this is clear from context). No extra value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves paragraphs from a completed transcript. It uses a specific verb 'Get' and resource 'completed transcript split into paragraphs', distinguishing it from sibling tools like assemblyai_get_sentences (sentences) and assemblyai_get_transcript (full transcript).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when paragraphs are needed but does not explicitly state when to use this tool over alternatives like assemblyai_get_sentences. No prerequisites are mentioned, such as the transcript being in 'completed' status, which is critical for correct invocation.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. Description does not disclose any behavioral aspects such as rate limits, data source freshness, or error handling, leaving the agent uninformed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no filler. Efficient for a simple tool, though could benefit from a brief note on code format.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with one parameter and no output schema, the description is adequate but misses the code format detail, which is critical for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%. Description mentions 'by code' but does not clarify the expected format (e.g., ISO alpha-2 or alpha-3). The parameter type is just 'string' with no further guidance.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'Get', resource 'country', and criterion 'by code'. Distinguishes from sibling tools like country_by_name or country_by_region.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit when-to-use or alternatives mentioned. Usage is implied from the name and description but lacks guidance on when to prefer this over other country lookup tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavior but only states 'list' and optional filters. It omits key details: pagination (despite page/page_size in schema), authentication requirements (api_key/app_key), or read-only nature. This is insufficient for a listing tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words, but it may be too sparse. Adding pagination or output hints could improve without sacrificing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema exists, yet the description does not explain return values or pagination behavior. For a listing tool with page/page_size parameters, this is a significant gap in completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with clear parameter descriptions. The description adds 'optional name or tag filters' which mirrors the schema but does not provide additional context. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the verb 'List', the resource 'Datadog monitors (alerts)', and optional filters by name or tags. This clearly differentiates it from sibling tools like get_monitor or create_monitor.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for listing monitors with optional filters but does not explicitly guide the agent on when to use this tool vs. alternatives like datadog_get_monitor for a single monitor or datadog_list_dashboards for other resources.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description does not disclose key behaviors like asynchronous submission, result retrieval, or auth/authz details.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, concise, and front-loaded with key action and supported formats, but lacks structure for additional context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema and sibling tools for text translation, the description misses critical info about asynchronous nature and result handling.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers all parameters with descriptions (100% coverage). The tool description adds minimal semantic value beyond listing document types.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the tool submits a document for translation via DeepL, lists supported formats (PDF, Word, PowerPoint), and implicitly distinguishes from deepl_translate_text.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Usage is implied: use for document translation, but no explicit comparison to sibling deepl_translate_text or guidance on when not to use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavioral traits. It only states that the tool gets details, without mentioning any potential side effects, authentication requirements, rate limits, or response characteristics.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that is well-structured and front-loaded, with no wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With three parameters, no output schema, and no annotations, the description is too brief. It does not explain what 'details' entails, the return structure, or any prerequisites for successful invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Only one of three parameters (includes) has a description in the schema, and the tool description adds no additional meaning beyond what the schema provides. The api_key and listing_id parameters are not explained, leaving ambiguity about their purpose and format.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get details'), the resource ('a single Etsy listing'), and the identifier ('by listing ID'), which is specific and distinguishes it from sibling tools like etsy_search_listings.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no explicit guidance on when to use this tool versus alternatives. While the purpose implies usage when a listing ID is known, it does not mention exclusions or provide context relative to siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the full behavioral burden. It implies a read-only operation but does not disclose authentication requirements beyond the token, rate limits, or potential side effects. The basic nature of 'get' is assumed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that directly states the tool's purpose without extraneous words. Every word adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given that no output schema is provided, the description partially covers return details (pages, frames, component count) but does not mention the full structure or potential additional metadata. For a moderately complex tool, more completeness would be beneficial.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 67% (2 of 3 parameters have descriptions in schema). The description does not add any parameter-specific meaning beyond the schema; it only lists output fields. With moderate coverage, a baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves a Figma file's structure and metadata, listing specific elements like pages, frames, and component count. This specificity distinguishes it from siblings such as figma_get_comments or figma_get_node.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives like figma_get_node or figma_get_images. The description lacks context on prerequisites, exclusions, or preferred scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must carry the full behavioral burden. It only states the function without disclosing any behavioral traits like authentication requirements, pagination, ordering, or possible side effects. It implies a read operation but lacks detail.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that immediately communicates the core function. It is concise with no extraneous information, making it easy to parse.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (2 optional params, no output schema), the description is adequate but incomplete. It does not mention what the output list contains (e.g., app names, IDs) or handle edge cases like no apps found. It meets the minimum but leaves gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% description coverage for both parameters (api_key and org_slug). The description does not add meaning beyond what the schema already provides, so the baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List', the resource 'Fly.io apps', and the scope 'in your organization'. It effectively distinguishes from sibling tools like fly_list_machines and fly_list_volumes, which list different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no usage guidance, such as when to use this tool versus alternatives like fly_get_app for a single app or fly_list_machines for machines within an app. No exclusions or context are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. It only states 'Get...' implying read-only, but fails to disclose pagination (page parameter), rate limits, or any other behavioral traits beyond what's obvious. Minimal value added.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence of 7 words, perfectly concise with no fluff. Efficiently communicates core purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Missing parameter explanations, no output schema, no return value description, and no differentiation from siblings. For a tool with 2 parameters and no annotations, this is inadequate for an agent to use correctly without additional context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage; description does not mention parameters at all. It does not explain valid categories or the page parameter's role, leaving the agent to infer from the name alone. Insufficient compensation for schema gaps.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly identifies the tool's purpose: retrieving food products by category from Open Food Facts. It uses specific verb 'Get', resource 'food products', and method 'by category', distinguishing it from siblings like food_search and food_get_product.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the tool is for category-based product retrieval but does not explicitly state when to use it versus alternatives like food_search. With multiple sibling tools, lacking guidance on trade-offs reduces the score.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description does not disclose behavioral traits such as read-only nature, rate limits, authentication requirements, or data size. The brief description provides minimal behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that is front-loaded with the action and resource. It is not verbose, though it could benefit from slightly more detail without sacrificing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no parameters, no output schema, and no annotations, the description is very incomplete. It fails to explain what 'bootstrap data' entails (e.g., the full static data from the FPL API) or provide any contextual hints for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The tool has zero parameters, and schema coverage is 100%. Per guidelines, a baseline of 4 is appropriate since there is no need to explain parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'Fantasy Premier League bootstrap data' with an explicit listing of data types (players, teams, etc.). It differentiates from sibling tools like fpl_fixtures or fpl_player by indicating it returns a broad static dataset.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. With many sibling tools focusing on specific FPL aspects, a note on using this for initial data loading or as a base for other calls is missing.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. It only mentions 'Interact with the GitHub REST API' and lists actions. No disclosure of rate limits, authentication requirements (though schema hints), idempotency, or side effects (create issue is write but not flagged). Significant gap for a multi-action tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, 20 words, front-loaded with service name and action list. Efficient but could be clearer with bullet points. No waste, appropriately sized.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Tool has 12 parameters and no output schema or annotations. Description lacks return format, pagination info, parameter interactions, or action-specific details beyond names. Incomplete for an AI to fully understand usage without referencing schema heavily.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% (all 12 parameters described). Description adds no parameter meaning beyond the schema; it only lists high-level actions. Baseline 3 applies as schema already covers parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly lists specific GitHub API actions (search repos, get repo details, list/create issues, list PRs, get user profiles, list gists, search code) and distinguishes from sibling gitlab_action (GitLab). Verb 'Interact with the GitHub REST API' plus action enumeration provides specific verb+resource.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit when-to-use or when-not-to-use guidance. The action list implies usage for GitHub operations, but lacks exclusions or alternatives. Sibling tools are for other services, so the context is somewhat clear, but no explicit guidelines are provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description lacks behavioral details such as pagination behavior, rate limits, or the format of returned posts. It only states a high-level action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, highly concise and front-loaded. It communicates the core purpose without filler, but omits parameter details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one optional parameter and no output schema, the description is moderately complete. It specifies the source and type of content but lacks structure details about the returned posts.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has one optional parameter (limit) with no description coverage. The tool description does not explain the parameter's purpose or effect, leaving the agent to infer from the schema alone.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's function: retrieving Ask HN posts from Hacker News. It distinguishes itself from sibling tools like hn_show_hn and hn_top_stories by specifying the post type.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives like hn_show_hn or hn_top_stories. The usage is implied but not clarified.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description is the sole source of behavioral insight. It fails to disclose any behavioral traits such as whether the tool is read-only, how results are ordered (e.g., by rating), or any limits on the returned list. The minimal description does not compensate for the missing annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence that efficiently conveys the tool's core purpose without any extraneous words. It is as concise as possible for a simple retrieval tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple schema (2 parameters, no output schema) and absence of annotations, the description is adequate for a straightforward top players list. However, it lacks critical details such as what fields the response contains (e.g., username, rating) and whether the 'nb' parameter is required or has a default. This leaves the agent needing to infer from the schema alone.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds meaning for the perfType parameter by referring to 'game mode', but it does not explain the 'nb' parameter, which is undocumented in the schema. Since schema coverage is 50%, the description could have clarified 'nb' but did not, resulting in marginal added value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves top Lichess players filtered by a specific game mode (perfType). It uses a specific verb ('Get') and resource ('top Lichess players'), and implicitly distinguishes from sibling tools like lichess_user (single user) or chess_leaderboards (different platform).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as chess_leaderboards or lichess_user. There is no mention of context, prerequisites, or exclusions, leaving the agent without decision support.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description must carry the burden. It only says 'list all audiences' but does not disclose pagination, rate limits, or any side effects. For a read operation, it is vague.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no redundant information. It directly communicates the tool's purpose efficiently.

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple search tool with three parameters and no output schema, the description is too minimal. It omits essential contextual details like parameter descriptions, result expectations, and behavioral constraints, leaving the agent underinformed for proper invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning beyond parameter names. 'query', 'artist', and 'limit' are not explained; their use and format are left entirely to inference. The description fails to compensate for the lack of schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches for recordings/tracks on MusicBrainz, specifying both the action (search) and the resource (recordings/tracks). This distinguishes it from sibling tools like mb_search_artists and mb_search_releases.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implicitly guides the agent to use this tool for recordings/tracks, but it lacks explicit when-to-use, when-not-to-use, or alternative tool recommendations. The agent must infer from the resource name, which may not be sufficient for nuanced decisions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description should disclose behavioral traits. It only states the core action but omits important details such as cost, rate limits, model selection implications, and that an API key (required) is needed.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity (multiple parameters, no output schema), the description is too brief. It does not explain what embeddings are, how to use the tool effectively, or what the output format looks like.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 60% with some parameters having descriptions. The description adds no additional meaning beyond the schema; it does not mention the undocumented api_key or org_id parameters or provide any usage context.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Create' and the resource 'vector embeddings for text using an OpenAI embedding model.' It distinguishes well from sibling embedding tools from other providers and other OpenAI tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for creating embeddings but provides no explicit when-to-use, when-not-to-use, or alternatives. No guidance on prerequisites or selection among similar embedding tools.

    Adequate for a simple list tool, but lacks details on return format and when to use. Could be more complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description adds minimal value, merely repeating that filters are available.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists who is currently on-call in PagerDuty, with optional filters. This distinguishes it from sibling tools that deal with incidents and services.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. No mention of prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must cover behavioral traits. It only states it lists all services with optional name filter. It omits details like pagination, rate limits, authentication requirements beyond api_key, and what happens on empty results, leaving significant gaps.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence covering the main purpose. It is front-loaded and efficient, though could include more context without being verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with no output schema, the description lacks details on response format, pagination, and prerequisites. The calibration example for a similar tool scored higher due to more complete context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description only repeats the name filter capability already in the schema ('Filter services by name'), adding no new meaning for the other parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List', resource 'services', and scope 'in a PagerDuty account', with an optional name filter. This distinguishes it from sibling tools like incident or oncalls, which are different entities.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for listing services, but does not explicitly state when to use this tool versus alternatives. There are no sibling service tools, so it's not misleading, but guidance on when to choose this over other PagerDuty tools is absent.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so the description carries full burden; it lacks behavioral details such as authentication (api_key not mentioned as required), error handling, rate limits, or idempotency, providing minimal context beyond the core functionality.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences front-load the purpose and key outcome, with no wasted words, making it efficient and easy to parse.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 11 parameters and no output schema or annotations, the description is too brief to cover authentication, message formatting, or error scenarios, leaving significant gaps for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds no parameter-specific guidance, despite 36% of parameters lacking schema descriptions. The agent must rely solely on the schema, which is insufficient for undocumented params like system_prompt.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly identifies the tool as a search-augmented chat completion that returns grounded answers with citations, distinguishing it from other plain chat completion siblings like openai_chat_completion.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for search-augmented queries with citations but does not explicitly state when to use this over alternatives or when not to use it, leaving it to inference.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Discloses the core behavior (generation, optional image animation, returned generation_id) but omits details on asynchronous nature, rate limits, failure modes, or required permissions beyond the api_key parameter. No annotations force full burden on description.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences that efficiently convey the main action, optional feature, and return value. Front-loaded with the core purpose. No extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Adequate for a simple generation tool with many parameters, but lacks context on parameter usage (e.g., how duration or style affect output) and does not mention the related polling tool (pika_get_generation).

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with good parameter descriptions. The description adds value by clarifying the return value (generation_id) which is not in the schema, but does not further explain parameters beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it generates an AI video from text, with optional image animation, and notes the return of a generation_id. However, it does not differentiate from sibling tools like kling_generate_video or runway_generate_video.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool vs alternatives or prerequisites. The description implies usage by mentioning optional animation and polling, but lacks when-not or alternative references.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral disclosure. It does not mention that this is a read-only operation, nor does it describe the return structure, rate limits, or any side effects. The minimal description leaves significant gaps in transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at six words, front-loading the core purpose. Every word is necessary, and there is no wasted content.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity of the tool and the thorough input schema, the description adequately conveys the main action. However, the lack of output schema or mention of return values slightly reduces completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% coverage with descriptions for all parameters, so the schema already provides sufficient meaning. The tool description adds no additional parameter information, resulting in a baseline score of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and the resource ('accounts for a Plaid-linked item'). It is distinct from sibling tools like plaid_balances and plaid_transactions, effectively specifying its unique purpose.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. Given the presence of multiple Plaid-related siblings, the lack of usage context makes it harder for an agent to choose appropriately.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden for behavioral disclosure, but it only states the action. It does not mention pagination (though implied by count/offset), rate limits, response format, or what happens when no templates exist. This is inadequate for a list operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, compact sentence with no wasted words. It is front-loaded with the essential action and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and simple parameters, the description is minimally adequate. However, it lacks information about the response (e.g., returned template fields like name and ID), which would be helpful for an agent to interpret results. A more complete description would mention that it returns a list of available templates.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema provides descriptions for all parameters (100% coverage), so the description adds no additional meaning. The baseline of 3 is appropriate since the schema does the heavy lifting.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('List') and resource ('email templates') with scope ('stored in Postmark'), making it clear what the tool does and distinguishing it from siblings like 'postmark_get_template' (which retrieves a single template) or 'postmark_send_email'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No usage guidance is provided. The description does not indicate when to list templates versus when to use 'postmark_get_template' for a specific template, nor does it mention pagination behavior or prerequisites beyond the required API key.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description must fully disclose behavioral traits. It only states the action (listing) without mentioning side effects, permissions, or output format. While listing is inherently non-destructive, the lack of details like 'returns a list of model IDs' reduces transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no extraneous words, perfectly sized for a simple list tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one parameter, no output schema), the description is adequate but lacks details about the return format (e.g., model IDs, names) or any pagination behavior, which could be useful for the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% coverage with a description for the api_key parameter. The description adds no additional meaning beyond 'list available models', so it meets the baseline but does not exceed expectations.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's action ('List') and context ('available Runway ML video generation models'), which is specific and distinguishes it from sibling tools like runway_generate_video and runway_get_task.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, typical use cases, or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the behavioral disclosure burden. It indicates a write operation (creating/updating identity) but does not disclose idempotency, error handling, permissions, or rate limits. This is minimal disclosure for a mutation tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that is clear and concise with no redundancy. It is appropriately sized for a simple tool, though it could benefit from additional structured information without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema and moderate parameter count (5), the description lacks details about return values, error conditions, and parameter optionality. It does not explain that 'user_id' and 'anonymous_id' are optional or the effect of omitting them. This leaves gaps for the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all 5 parameters. The description adds context about linking anonymous ID to user ID and traits, but does not provide significant additional meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool identifies a user in Segment by linking an anonymous ID to a known user ID, with traits. This verb+resource specification distinguishes it from siblings like 'segment_track_event'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for user identification in Segment but does not provide explicit when-to-use or when-not-to-use guidance. No alternatives are mentioned, though the context of sibling tools suggests differentiation.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as idempotency, rate limits, or whether the event is created or updated. The minimal description fails to compensate for the lack of annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with two sentences, front-loading the main action and providing examples without extraneous words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has 6 parameters with nested objects and no output schema. The description is adequate for a simple tracking tool but lacks guidance on optional parameters like user_id vs anonymous_id and what the response looks like.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% (all parameters have descriptions), so the baseline is 3. The description does not add any additional parameter meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool tracks a custom event in Segment and provides concrete examples like 'Signed Up'. However, it does not differentiate from sibling tool mixpanel_track_event which serves a similar purpose.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for recording user actions but lacks explicit guidance on when to use this tool versus alternatives, or any prerequisites.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description should disclose behavioral traits like return format, authorization requirements, rate limits, or side effects. It only states 'Track', omitting all such details.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 7 words, extremely concise and front-loaded with the action. Every word earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no annotations, no output schema, and no parameter descriptions, the description is inadequate. It does not explain what the tool returns or any behavioral context needed for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning beyond parameter names. It mentions 'tracking number' for tracking_id but ignores api_key entirely. The description fails to compensate for the lack of schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses the specific verb 'track' and clearly identifies the resource as 'Sendle parcel' with the required input 'tracking number'. It is unambiguous and distinct from other tools in the list, though siblings like 'auspost_track_parcel' exist for other carriers.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when you have a Sendle tracking number but does not explicitly state when not to use it or provide alternatives such as 'auspost_track_parcel' for other carriers. The context is clear but lacks exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It only states 'creates or updates' without disclosing side effects, authentication requirements, or error conditions. Lacks details on behavior when pack_id already exists.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences front-loaded with the action. No unnecessary words; every sentence adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with two string parameters and no output schema, the description covers core purpose but lacks usage context and behavioral details. Adequate but not comprehensive.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with clear descriptions for pack_id and yaml. The description adds 'for the caller' but does not significantly enhance understanding beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool saves a TestPass pack YAML definition, with create/update semantics. It distinguishes from sibling tools like testpass_run or testpass_status by focusing on saving the pack definition.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like testpass_edit_item or other testpass tools. Missing context on prerequisites or scenarios where saving a pack is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is adequate for a low-complexity tool with one parameter and no output schema. However, it omits output format details and edge cases, so the agent may need to infer return structure.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has one parameter 'text' with 0% description coverage. The description adds value by listing output metrics but does not explain parameter constraints (e.g., length, language). Baseline 3 is appropriate given the simple parameter and partial compensation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Analyse' and the resource 'text', and lists specific metrics: word count, sentences, readability. This distinguishes it from sibling tools like text_count_occurrences or text_extract_emails.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it lists all available models on Together AI and explicitly enumerates the categories (chat, completion, embedding, image), which is specific and distinguishes the tool from similar list_models tools for other providers.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternative list_models tools for other AI providers or other Together AI tools like togetherai_chat_completion. The description does not mention prerequisites or context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. It only mentions pagination (cursor-based), but doesn't disclose read-only nature, auth expectations, rate limits, or handling of large datasets. For a browse operation, more behavioral context is needed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single front-loaded sentence with verb, resource, and key feature (pagination). No redundant words, efficient and to the point.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite 7 parameters and no output schema, the description is minimal. It doesn't explain cursor-based pagination fully, nor does it mention performance implications, error handling, or result format. More context would aid agent decision-making.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with parameter descriptions. The description adds no additional meaning beyond what's in the schema. Baseline 3 is appropriate as schema does the heavy lifting.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Browse', the resource 'all records in an Algolia index', and notes pagination style 'paginated cursor-based'. This distinguishes it from siblings like algolia_search (search) and algolia_get_object (single object).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit when-to-use or when-not-to-use guidance. It implies use when you need all records, but doesn't compare to alternatives like algolia_search for filtered browsing. The context is clear but lacks exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It only states the action without disclosing behavioral traits such as read-only nature, rate limits, or authentication requirements beyond the api_key parameter.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no extraneous information, appropriate for a simple list operation.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple nature of the tool and lack of output schema, the description is minimally adequate but does not specify return format or content, leaving the agent without details on what to expect.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage, and the tool description does not mention or explain the 'api_key' parameter. For a single required parameter, the agent receives no additional context from the description.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'list', the resource 'Claude models', and the scope 'available via the Anthropic API'. It distinguishes from sibling tools like 'anthropic_create_message' and other AI provider list models tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit when-to-use or when-not-to-use guidance is provided. Usage is implied as a prerequisite for other Anthropic actions, but no comparison to alternatives like 'cohere_list_models' is made.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided. The description states it gets comments and ratings (a read operation) but adds no behavioral details beyond what the schema already provides (pagination via page parameter). For a simple read tool, this is minimally adequate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 9 words, concise and front-loaded. It efficiently communicates the purpose without extraneous information. However, it could be slightly expanded to include key details like pagination without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's low complexity (2 parameters, no output schema, no annotations), the description is complete enough to understand its function. However, it does not mention what the response contains or any usage constraints. For a tool of this simplicity, it is adequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with both parameters described (gameId and page). The description adds no additional meaning to the parameters beyond what is already in the schema, so a baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'user comments and ratings for a board game on BGG'. It distinguishes from siblings like bgg_game_details (game details), bgg_search (search), bgg_top_games (top games), and bgg_user_collection (user collection) by focusing specifically on comments and ratings.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., bgg_game_details for full game info, bgg_search for finding games). It does not include any 'when to use' or 'when not to use' information.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description bears full responsibility for behavioral disclosure. It only states the action of triggering a pipeline, omitting that this is a mutating operation, potential side effects (e.g., building, costing credits), authentication implications, or return behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that front-loads the action ('Trigger a new...') and presents optional parameters succinctly. No extraneous words or redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters, no output schema, and no annotations, the description is too sparse. It fails to explain what the tool returns (e.g., pipeline ID, status), error scenarios, or additional contextual constraints like rate limits or required permissions.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the input schema already documents all parameters. The description adds no semantic value beyond restating that branch, tag, or parameters are optional, which is already clear from the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool triggers a new CircleCI pipeline, with optional parameters for branch, tag, or parameters. It distinguishes from sibling tools like circleci_list_pipelines which are read-only, making the purpose specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage (triggering a pipeline) but provides no guidance on when to use this tool vs alternatives (e.g., circleci_get_pipeline for status checks). It lacks prerequisites like needing a valid API key and project slug beyond the schema, and no exclusions are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully disclose behavioral traits. It confirms the write operation but omits details on authentication, rate limits, error handling, or return values. The description only hints at required fields but does not explain consequences of invalid inputs.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is three sentences with no redundancy. It front-loads the primary purpose, then usage context, then key parameter info. It is efficient and well-structured.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of annotations and output schema, the description should cover more context, such as what the tool returns (e.g., comment ID, success status), error scenarios, and prerequisites. The current description is adequate only for basic purpose comprehension.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is low (25%). The description restates that target_kind is 'todo' or 'idea' and agent_id is required, but these are already evident from the schema. It adds no new meaning for agent_id or target_id, and the text parameter's max length is already in the schema. The description fails to compensate for the lack of schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Adds a comment to a Boardroom todo or idea') and distinguishes it from top-level messaging by specifying scope. The verb+resource combination is specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides explicit when-to-use guidance ('Use for discussion that belongs scoped to that item rather than as a top-level Boardroom message'). While it does not list alternatives or when-not-to-use, the context is sufficiently clear for an AI to decide.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden for behavioral disclosure. It only states basic functionality, omitting details on edge cases (e.g., unknown language), return format, or error behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no wasted words. It is appropriately sized for the tool's simplicity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple lookup with one parameter and no output schema, the description is adequate but lacks parameter format guidance and behavioral details, leaving the agent to infer missing information.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage, and the description merely mentions 'by language' without specifying the expected format (e.g., code vs. name). This fails to compensate for the schema's lack of detail.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get countries by language from REST Countries' uses a specific verb and resource, and implicitly distinguishes from sibling tools like country_by_code or country_by_name by specifying the filtering criterion 'by language'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage context (filtering by language) but provides no explicit guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and description gives no behavioral details (e.g., how trending is determined, limits, pagination). Without output schema, the description is insufficient for an agent to understand output behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise 7-word sentence that front-loads the core action and resource. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite simplicity, the description lacks completeness: no output schema, no behavioral details, no usage context. A tool with no parameters still needs guidance on what data it returns.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Tool has zero parameters, so baseline is 4. No additional parameter info needed; description is adequate as is.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'get', resource 'trending cryptocurrencies', and source 'CoinGecko'. Among sibling crypto tools (crypto_top_coins, crypto_search, etc.), it uniquely identifies itself as trending, making purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives like crypto_search or crypto_top_coins. Lacks context about what 'trending' means or typical use cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden for behavioral disclosure. It only states it's a query (read operation) but omits details like authentication requirements (implicit via schema), rate limits, or error handling. Adds minimal transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no wasted words. It effectively communicates the core purpose in minimal space.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 5 parameters and no output schema, the description is too minimal. It does not explain return values, pagination, or usage patterns. A tool of this complexity would benefit from more contextual information.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the description adds no additional meaning beyond what each parameter's schema description already provides. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses specific verb 'Query' and resource 'Datadog metrics time-series data', clearly distinguishing it from sibling tools like datadog_list_dashboards or datadog_create_monitor.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for querying metrics but provides no explicit guidance on when to use versus alternatives or any prerequisites. It does not mention other Datadog tools for comparison.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral disclosure. It states it returns 'details' but does not specify what those details include (e.g., venue, date, status), nor any side effects, prerequisites, or authorization requirements.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence that is appropriately sized for a simple tool. It is front-loaded with action and resource, but lacks any structure (e.g., bullet points) that could enhance readability for complex cases.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool lacks an output schema and has no description of return values. The description should inform the user what 'details' means, e.g., typical fields or structure, to be complete for an agent relying on the description alone.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 2 parameters (event_id required, api_key optional) with 0% description coverage. The description only explains event_id by mentioning 'by ID', but does not explain api_key or its necessity, failing to compensate for the schema's lack of descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get details for an Eventbrite event by ID' clearly specifies the verb (get), resource (Eventbrite event), and method (by ID), distinguishing it from siblings like eventbrite_search_events or eventbrite_get_attendees.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description clearly indicates when to use the tool: when you have an event ID and need its details. It implies the context of ID-based retrieval but does not explicitly exclude alternatives or mention when not to use, which slightly lowers the score.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It only mentions the action and pinning, omitting authentication requirements, error behavior, rate limits, or return format. The agent gets minimal behavioral insight.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that immediately conveys the tool's core purpose. It is front-loaded with the verb and resource, with the optional feature appended efficiently.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (5 params, no output schema, no annotations), the description covers the basic functionality but lacks details on authentication sources, error scenarios, and response shape. It is minimally adequate for a straightforward create operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 40% (x and y have descriptions). The description does not add meaning to the three required parameters (personal_access_token, file_key, message) beyond their names. It references pinning coordinates but does not compensate for the uncovered parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's action ('Add a comment'), the resource ('to a Figma file'), and an optional feature ('pinned to canvas coordinates'). It distinguishes this creation tool from sibling tools like figma_get_comments, which are for reading.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the tool is for posting comments but does not explicitly contrast with read operations (e.g., figma_get_comments) or provide context on when to use it over alternatives. No when-not-to-use guidance is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral traits. It only mentions the data source and lookup method, omitting details like error handling, rate limits, or response format.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single efficient sentence with no superfluous words, front-loading the key information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity (one param, no output schema), the description is barely adequate—it lacks coverage of error cases, return structure, and parameter constraints.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description adds basic semantics by stating 'by barcode', clarifying the parameter usage. However, with 0% schema description coverage, it does not fully compensate with expected format or examples.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get a food product from Open Food Facts by barcode', specifying the verb-resource pair and unique lookup method. This distinguishes it from siblings like food_by_category and food_search.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the burden of behavioral disclosure. It mentions lack of API key requirement but omits rate limits, error handling, or whether the operation is strictly read-only.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences with no wasted words. It front-loads the core purpose and immediately follows with return values and a key usage detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description is thin. It lists return fields but does not explain output format, pagination, or error states, leaving gaps for a tool with 6 parameters and no structural support.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema already documents all parameters well. The tool description adds no extra parameter details beyond what the schema provides, meeting the baseline with no additional value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Search global news via the GDELT Project' and lists the returned fields (article titles, URLs, sources, dates, countries, languages), distinguishing it from sibling tools like gdelt_geo_events or gdelt_tone_analysis.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavior. It only states 'Get' without detailing authentication requirements, rate limits, or whether the profile is of the authenticated user or another user.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 7 words, front-loaded with verb and resource, with no wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read operation with one parameter and no output schema, the description is sufficient. It could optionally mention return fields, but not required for completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a clear description for api_key. The tool description adds no additional parameter meaning beyond what the schema already provides, so baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'authenticated Calendly user profile', which distinguishes it from other Calendly tools that deal with events, event types, and invitees.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like get_calendly_event or list_calendly_events, nor does it mention prerequisites or context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It reveals no behavioral traits such as error handling (e.g., if the article is not found), authentication requirements for the optional api_key, or rate limits. The description is too minimal for a tool without annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 9 words, extremely concise and front-loaded. It is appropriately sized for a simple retrieval tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (no output schema, two parameters), the description is minimally adequate: it identifies the resource and identifier. However, it lacks any mention of return format or error conditions, leaving gaps for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description only mentions 'ID' which implies article_id. It does not add meaning about the optional api_key parameter, its format, or usage. The description fails to compensate for the lack of schema documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get a specific Guardian article by ID,' using a specific verb and resource, and the 'by ID' qualifier distinguishes it from sibling tools like guardian_search_articles or guardian_get_sections.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The purpose implies usage when you have an article ID, but there is no explicit guidance on when to use this tool versus alternatives, nor any prerequisites or when-not-to-use information.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavioral traits. The description only says 'Check the generation status', lacking details on authentication requirements (api_key), rate limits, or the nature of the status response. The tool is read-only, but this is not explicitly stated.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, short sentence with no wasted words. It is appropriately front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema, the description should hint at the return format (e.g., possible statuses). It does not. The tool is simple, but the description lacks sufficient completeness for an AI agent to fully understand the response.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description adds no additional meaning beyond the schema; it mentions 'by video ID' which is already documented.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the tool checks generation status of a HeyGen video by video ID. It uses a specific verb ('Check') and resource ('generation status of a HeyGen video'), and distinguishes from sibling tools like heygen_create_avatar_video.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not explicitly state when to use this tool vs alternatives, but the context from sibling tools and the parameter description ('Video ID returned by heygen_create_avatar_video') implies usage after video creation. No explicit alternatives or exclusions are provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden of behavioral disclosure, yet it only states the basic purpose. It does not mention important traits such as api key requirements, rate limits, async behavior, supported image formats, or error handling.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (one sentence) and front-loads the core action. Every word is used effectively with no redundancy or filler.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite having 7 parameters and no output schema, the description fails to explain what the output looks like (e.g., image URL), how to handle results, or any constraints like size limits. It lacks guidance for a generative tool with multiple optional parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All 7 parameters are fully described in the input schema (100% coverage), so the description does not need to add much. It adds value only by referencing higgsfield_get_styles for the style parameter, but otherwise does not enhance parameter understanding beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool generates an image from a text prompt using Higgsfield AI, distinguishing it from sibling tools like video generation and style listing. The verb 'Generate' and resource 'image from a text prompt' are specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for image generation but does not explicitly state when to use it over alternatives like higgsfield_generate_video. The style parameter references higgsfield_get_styles, hinting at a prerequisite, but no direct when-not-to-use guidance is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It reveals the tool emits a wake packet when verified, but lacks detail on side effects, idempotency, or dependencies. The statement about not editing code helps, but overall transparency is insufficient for a mutation-like tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise: two sentences, front-loaded with the primary purpose, followed by a clear exclusion list. Every sentence adds value with no wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite 100% schema coverage, the description does not explain the workflow or how this tool fits with siblings like nudgeonly_receipt_bridge. It also lacks guidance on the 13 optional parameters and expected output for a tool with no output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all 13 optional parameters. The tool description adds no additional meaning beyond what the schema already provides, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's specific action: consume a NudgeOnly receipt bridge result and emit a compact IgniteOnly worker wake packet when verified. It also explicitly lists actions it does NOT perform (edit code, merge, approve, close, mark done), distinguishing it from potential sibling tools that might do those.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides implied usage context by stating what it never does, but does not explicitly say when to use this tool versus alternatives like nudgeonly_receipt_bridge or igniteonly_api. No direct guidance on prerequisites or scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full behavioral transparency burden. It indicates asynchronous operation by mentioning a task_id for polling, but lacks details on auth requirements (beyond API key), error handling, rate limits, or failure modes. Some context provided, but insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, 23 words, front-loaded with the core purpose. Every sentence adds value with no redundancy. Excellent conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 9 parameters, 100% schema coverage, and no output schema, the description adequately covers the main functionality and async nature. However, missing details on error handling and expected completion times reduce completeness slightly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description adds minimal extra meaning—only referencing mode and the return of task_id (which is not a parameter). It does not enhance understanding of parameters beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool generates a high-quality video from text using Kling AI, with support for standard and professional modes. It identifies the provider but does not explicitly differentiate from similar video generation siblings like pika_generate_video or runway_generate_video.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool over alternatives. It mentions modes but does not explain when to choose standard vs professional or how this compares to other video generators.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description must fully convey behavioral traits. It only states it 'gets' the puzzle, but does not mention that it is a read-only operation, whether authentication is needed, rate limits, or the response format.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, efficient and front-loaded. However, it is extremely terse and lacks any explanatory context beyond the bare minimum.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has no parameters, no output schema, and no annotations, the description is minimally adequate. It does not explain what constitutes a 'daily puzzle' or the output structure, but for a simple retrieval tool this may be acceptable.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has zero parameters, so the description does not need to explain parameters. Baseline for 0 params is 4, and the description correctly implies no parameters are needed.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and the resource ('the Lichess daily puzzle'). It distinguishes from siblings like 'lichess_puzzle_random' by specifying 'daily'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives like 'chess_puzzles_random' or other puzzle tools. No context provided for usage scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description must carry the full burden. It discloses the core behavior (broadcast to all followers) and implies mutation. However, it does not mention irreversible nature, potential costs, rate limits, or required permissions, which are important for a broadcast operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no wasted words. Every word serves a purpose, making it highly concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple 2-parameter tool with no output schema, the description provides the basic purpose but lacks sufficient context about parameter usage, access token sourcing, or response behavior. It is adequate but not fully complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate. It fails to mention either parameter, leaving the agent to infer that 'channel_access_token' and 'message' are needed. No hints on format, validation, or constraints are provided.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool broadcasts a text message to all followers of a LINE Official Account. 'Broadcast' and 'all followers' distinguish it from other LINE tools like line_send_message, which targets specific users.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like line_send_message or line_reply_message. No mention of prerequisites, context, or situations where broadcasting is appropriate or inappropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden. It implies upsert behavior (add or update), which is a key behavioral trait. However, it does not disclose potential side effects (e.g., sending confirmation email if status changes) or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that conveys the essential purpose without any filler. It is efficiently front-loaded and earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 6 parameters and no output schema, the description fails to explain the success/error response format or what happens on duplicate email. It is too brief to be complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, and the description adds no additional meaning beyond the parameter names and types. The description does not explain how parameters interact (e.g., first_name/last_name only relevant for subscribed status).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Add or update') and the resource ('a subscriber in a Mailchimp audience'). It distinguishes from sibling tools like mailchimp_list_members or mailchimp_search_members by focusing on modifying a single subscriber.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., list_id must exist), nor does it suggest when not to use it (e.g., for bulk operations).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden of behavioral context. It does not disclose that the tool is read-only (search operation), any authentication needs beyond the api_key parameter, rate limits, pagination behavior, or what happens if the query returns no results.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that immediately conveys the primary action and scope. No unnecessary words or redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of annotations and output schema, the description is insufficiently complete. It does not explain return format, whether it supports partial matching, case sensitivity, or how results are ordered. A search tool requires more context for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description adds minimal value by clarifying that list_id is optional ('across all or a specific audience'), but it does not elaborate on parameter formats or constraints beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Search for subscribers' and specifies the scope 'across all or a specific Mailchimp audience'. This distinguishes it from sibling tools like mailchimp_list_members (which lists members of a specific audience) and mailchimp_add_member (which adds a member).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for searching subscribers but does not explicitly guide when to use this tool over siblings like mailchimp_list_members or mailchimp_add_member. No when-not-to-use conditions are provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description fails to disclose behavioral traits such as authentication requirements, pagination, rate limits, or side effects. The limit and type parameters hint at pagination/filtering but are not explained.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with verb and resource. No extraneous words, perfectly concise for a simple list operation.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, and description does not describe the response format, pagination, or error conditions. For a tool with 4 parameters (2 optional), more context is needed to fully inform an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description adds no additional meaning beyond the schema; e.g., the 'type' parameter is not mentioned. The description is minimal and does not enhance parameter understanding.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (List), resource (Mapbox tilesets), and ownership scope (owned by a user). It distinguishes this tool from sibling Mapbox tools like mapbox_geocode_forward, mapbox_get_directions, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use or alternatives, but the tool's purpose is straightforward and sibling tools cover different functionalities, so usage is implied.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully disclose behavioral traits. It only states 'Get' implying a read operation, but fails to mention requirements for valid MBID, error handling, rate limits, or authentication needs.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence that efficiently conveys the core functionality with no unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple lookup tool with one parameter and no output schema, the description is adequate but lacks information about the response format, error cases, or validation. It is minimally sufficient.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The parameter 'mbid' has no description in the schema (0% coverage), and the tool description adds no additional meaning beyond its name. It does not explain what an MBID is or its expected format.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'MusicBrainz artist', and the lookup method 'by MBID'. This distinguishes it from sibling tools like mb_search_artists which search by name.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide explicit guidance on when to use this tool versus alternatives like mb_search_artists. The purpose is clear from the name and description, but no when-to-use or when-not-to-use context is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. It only states the filtering action; no disclosure of error handling, return format, or behavior for invalid area inputs. Lacks critical behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise single sentence with no fluff. Every word is necessary for the core message.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple tool (one param, no output schema), the description is too sparse. It fails to explain what the tool returns, any assumed default behavior, or limitations. Incomplete for reliable invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage. The description adds 'cuisine/area' context, suggesting 'area' refers to cuisine regions, which adds meaning beyond the schema's parameter name alone. However, it does not specify format or valid values.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Filter meals') and the criterion ('by cuisine/area'), distinguishing it from sibling tools like meal_filter_by_category and meal_filter_by_ingredient.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives (e.g., meal_search or other filters). The description implies use when filtering by area/cuisine, but lacks exclusions or mention of sibling tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully describe behavior. It only states 'random' without clarifying the distribution, constraints, or whether it returns a meal name, full recipe, or just a dish.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise: four words in one sentence. Every word is necessary and there is no redundancy. It is front-loaded and efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and annotations, the description should provide more context about what kind of data is returned (e.g., meal name, ingredients, instructions). It is insufficient for an agent to understand the tool's output.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    There are zero parameters, and schema coverage is 100%. The description adds no parameter info but none is needed. Baseline of 4 is appropriate for tools with no parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and the resource ('a random meal/recipe'). It is specific and distinguishes itself from sibling tools like meal_search or meal_filter_by_*, which are for targeted queries.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    There is no guidance on when to use this tool versus alternatives. It does not mention that this is for random discovery or when the user does not have a specific meal in mind.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description only states 'List all projects' without disclosing behavioral traits such as pagination behavior (despite a cursor parameter), whether results are ordered, API key authentication requirements (though key is in schema), or rate limits. The description carries the full burden for transparency but reveals very little beyond the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence that is front-loaded with the core action and resource, with zero wasted words. Every word contributes to understanding.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema is provided, and the description does not explain what the response contains (e.g., list of project IDs, names, status). For a tool with three parameters including pagination, the description is too sparse; it does not specify the response structure or how to handle pagination to retrieve all projects.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% coverage with descriptions for all three parameters (api_key, limit, cursor). The description adds no additional meaning beyond the schema, so it meets the baseline of 3 for high schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'List all Neon Serverless Postgres projects in your account' – a specific verb ('List') and resource ('Neon Serverless Postgres projects') with account scope, distinguishing it from siblings like 'neon_get_project' (single project) and 'neon_list_branches' (branches inside a project).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for obtaining a list of all projects but provides no explicit guidance on when to use this tool versus alternatives like 'neon_get_project' or 'neon_list_databases'. There is no when-not-to-use or alternative naming, so the guidance is only implied.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It clearly states the tool is deterministic, read-only, and makes no ownership decisions or completion state changes. However, it does not disclose prerequisites (e.g., must receive output from nudgeonly_api) or error behavior for missing inputs, leaving some gaps.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is exceptionally concise: two sentences, approximately 25 words. Every word adds value, clearly stating the action and constraints. Front-loaded and efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite conciseness, the description lacks completeness given the tool's complexity (16 optional parameters, no output schema, no required fields). It does not explain how parameters influence the output path (receipt vs. escalation) or what the tool returns. The agent needs more context to use it effectively.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Input schema coverage is 100% with each parameter described. The description adds no additional meaning beyond what the schema provides; it only summarizes the tool's purpose. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's function: turning a verified NudgeOnly painpoint into a worker receipt request or WakePass escalation candidate. It specifies the resource and output types, and the phrase 'no writes, no ownership decision, no completion state' helps distinguish it from siblings, though it does not explicitly differentiate from all sibling tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides context on when to use the tool ('Deterministic bridge only') and what it does not do, but lacks explicit guidance on when to use this vs. alternatives like pushonly_wake_pusher or igniteonly_receipt_consumer. The agent must infer usage from the behavioral constraints.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully disclose behavioral traits. It mentions fetching a page and scanning visible text, but does not explain rendering behavior (e.g., JavaScript execution), limitations (e.g., page size, rate limits), or that it is read-only. This lack of detail could lead to misuse.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise: two sentences cover the action (fetch and scan), the target (em/en dashes and banned words), and the output (occurrences with context). No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema is provided, so the description should clearly specify the return format. 'Returns every occurrence with surrounding context' is vague—does it return a list of objects? What fields? Additionally, error handling for unreachable URLs is not mentioned. The description is incomplete for confident use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description adds value by explaining that the tool specifically checks for em/en dashes and banned words, and returns occurrences with context, clarifying the purpose of both parameters beyond their schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the tool fetches a page, scans visible text for specific dashes and a configurable list of banned words, and returns occurrences with context. This clearly distinguishes it from sibling tools which perform other quality checks (e.g., qc_run_checklist).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, nor does it mention any prerequisites or exclusions. Given the presence of sibling tools like qc_run_checklist, the absence of usage guidance is a notable gap.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden but is minimal. It does not disclose behavioral traits such as ordering, pagination, response format, or whether it includes country codes vs names. This is a significant gap for a list endpoint.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no wasted words. It is appropriately sized for a simple tool with no parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description should explain the return format (e.g., array of country names or objects). It omits this, making the tool's response unpredictable. Simple tool but incomplete for an agent to interpret results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has zero parameters with 100% coverage (empty). Per guidelines, baseline is 4, but the description adds no meaning beyond the schema. It does not clarify what 'countries' entails (e.g., names, codes, or full objects), reducing value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List all countries with radio stations' is a clear verb+resource statement. It distinguishes itself from siblings like radio_by_country, radio_search, and radio_by_tag by specifying that it lists all countries, not stations or filtered results.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives (e.g., radio_by_country for station details). Usage is implied as a high-level listing, but no when-not-to-use or alternative suggestions are provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description should disclose behavioral details (e.g., that it sends an email, requires authentication, potential side effects). The minimal phrase 'Send a transactional email' adds no transparency beyond the obvious.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words, efficiently conveying the tool's purpose without redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (10 parameters, no output schema), the description lacks crucial context such as what happens after sending (e.g., return value, error handling), rate limits, or dependency on a valid API key.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All 10 parameters have descriptions in the input schema, resulting in 100% coverage. The description adds no additional meaning beyond what the schema already provides, so it meets the baseline expectation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Send') and the specific resource ('transactional email via SendGrid'), differentiating it from other email-sending tools like email_send or postmark_send_email by specifying the provider and email type.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for transactional emails through SendGrid but provides no explicit guidance on when to use this tool versus alternatives, nor does it mention prerequisites like having a verified sender or API key.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as pagination, default ordering, result limits, or what happens when no filters are applied. This is a significant gap for a list tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that front-loads the action and key details. Every word is useful, with no redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite being a list tool with 7 parameters and no output schema, the description lacks details on result format, ordering, or pagination. It is incomplete for effective tool selection and invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 71%, and the description reiterates the filter parameters (game, category, user, status) without adding deeper semantics. The 'max' parameter is not mentioned, and the description does not compensate for the missing schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists speedruns and specifies the available filters (game, category, user, status). This distinguishes it from sibling tools like speedrun_get_game or speedrun_search_games, which have different purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description lists optional filters but does not provide explicit guidance on when to use this tool versus alternatives like speedrun_get_leaderboard. The usage context is implied but not directly compared to siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must cover behavioral traits. It mentions 'extract all phone numbers' but does not specify return format, handling of international formats, edge cases (e.g., no numbers), or what constitutes a phone number.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no wasted words. It is appropriately sized for a simple tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple extraction tool with one parameter, the description is adequate but has clear gaps. It does not mention the output structure, edge cases, or whether it handles punctuation or international formats.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 0% description coverage, so the description must add meaning. It only adds 'from a text' to clarify the 'text' parameter, which is minimal. No details on encoding, max length, or format expectations.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Extract all phone numbers from a text.' It uses a specific verb (extract) and resource (phone numbers), distinguishing it from sibling tools like text_extract_emails and text_extract_urls.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when phone numbers are needed, but provides no explicit when-to-use or when-not-to-use instructions. Sibling tools exist for other extraction tasks, but no guidance on alternatives is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description only says 'Delete'. For a destructive operation, more details about reversibility, required permissions, or side effects would be expected.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences, front-loaded with the action and resource, and contains no unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, the description is minimal but sufficient for a simple delete operation if the agent understands Vercel's API conventions. However, it lacks details on return values or error handling.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%. Only env_id is explained via the description (referencing vercel_get_env). project_id, team_id, and api_key are not described, leaving the agent to infer their purpose.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Delete'), resource ('Vercel environment variable'), and identifier ('env id'). It references a sibling tool for obtaining the id, making the purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description mentions getting ids from vercel_get_env, implying a prerequisite. However, it does not explicitly state when to use this tool over alternatives or provide guidance on required permissions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description discloses that votes are one per agent per idea and subsequent calls overwrite previous votes. Without annotations, this is the only behavioral insight; however, it lacks details on error handling, success response, or authorization requirements.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise, using one sentence plus a fragment. Every part adds value: the action, vote values, behavioral note, and required parameter. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers the core function and behavioral nuance (overwrite), but lacks information about idea_id, error cases, and any prerequisites. For a simple tool with no annotations or output schema, it is adequate but not fully complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description should explain each parameter. It only repeats 'agent_id required' (schema already marks it required) and mentions vote options as 'up' or 'down' (same as schema enum). It does not clarify idea_id or the role of agent_id.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses specific verb+resource: 'Cast or change your vote on an idea' and identifies the vote options ('up' or 'down'). It differentiates from sibling tools like create_idea, update_idea, and list_ideas by focusing solely on voting.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives (e.g., create_idea, update_idea). While the tool's purpose is clear, the description does not provide any exclusions or alternative tool comparisons.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as rate limits, error handling, or response format beyond stating the data source and lack of API key requirement.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that immediately conveys the purpose and key benefit, with no wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple, but without an output schema, the description should ideally mention what data is returned (e.g., temperature, conditions) to fully inform the agent; currently it provides only the bare minimum.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 0% description coverage, and the description does not explain the parameters (latitude, longitude, timezone) beyond their existence, though latitude/longitude are self-explanatory.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves current weather for a location from Open-Meteo and distinguishes it from sibling tools like weather_forecast and weather_hourly by specifying 'current' and noting 'no API key required'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description mentions 'no API key required' as a benefit, but does not provide explicit guidance on when to use this tool over sibling weather tools or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden for behavioral disclosure. It only states the basic action and does not mention side effects, idempotency, or potential failure modes. For a retrieval tool, the lack of any behavioral details beyond the core function is a gap.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that directly conveys the purpose without any extraneous words. It is front-loaded and every word contributes meaning.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the low complexity (2 simple parameters, no output schema, no annotations) and the context of sibling tools, the description is minimally adequate. It explains what the tool does and hints at prerequisites ('completed'), but does not specify the response format or error conditions. It is functional but could be more informative.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Both parameters already have clear descriptions in the input schema (api_key and transcript_id). The tool description adds no additional semantic information beyond what the schema provides. Schema coverage is 100%, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses the specific verb 'Get' and resource 'completed transcript', and adds 'split into individual sentences' which clearly distinguishes it from sibling tools like assemblyai_get_paragraphs. An agent can immediately understand what this tool does and how it differs from similar tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage by stating 'completed transcript', suggesting the transcript must already exist and be finished processing, but it does not explicitly refer to alternatives or provide when-to-use/when-not-to-use guidance. The contrast with assemblyai_get_paragraphs is implicit but not stated.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It states 'Get the status and results,' indicating a read-only operation. However, it does not disclose any behavioral traits such as potential polling, rate limits, or what happens if the job is not yet complete. The description is minimal and lacks depth for a non-annotated tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that is clear, direct, and front-loaded. Every word is necessary and there is no redundancy or filler.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has 2 required parameters and no output schema. The description does not explain what the response looks like (e.g., fields like status, text, confidence). While the schema covers parameters, the lack of output schema means the agent may not know what to expect. The description is adequate for a simple retrieval but could be more complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with both parameters (api_key, transcript_id) having descriptions in the schema. The description adds no additional meaning beyond what the schema already provides. With high schema coverage, the baseline score is 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Get the status and results of an AssemblyAI transcription job.' It uses a specific verb ('Get') and resource ('status and results of a transcription job'), distinguishing it from sibling tools like assemblyai_transcribe (which creates a job) and assemblyai_list_transcripts (which lists all jobs).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage after creating a transcription job via assemblyai_transcribe, as it requires a transcript_id. However, it does not explicitly state when to use this tool versus alternatives, nor does it provide exclusions or preconditions. The context is implied but not spelled out.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden of disclosing behavioral traits. It only lists return fields but does not mention any side effects, authentication needs, rate limits, or data freshness. For a read-only tool without annotations, more behavioral context is expected.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence (180 characters) that front-loads the purpose and efficiently lists the key fields. Every word adds value with no redundancy or waste.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has one required parameter, no output schema, and no annotations, the description adequately lists return fields but lacks behavioral context (error handling, ID format requirements, data availability). It is minimally complete for a simple lookup tool but could be improved.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with one parameter (gameId) described as 'BoardGameGeek game ID'. The description adds context by stating it retrieves details for a board game by its BGG ID and lists the returned fields, but does not add new semantics beyond the schema. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves full details for a board game using its BGG ID and lists the specific fields returned (name, year, rating, players, playtime, description, categories, mechanics). This distinguishes it from sibling tools like bgg_search (which searches) and bgg_game_reviews (which gets reviews).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies use when a BGG ID is known and full details are needed, but it does not explicitly state when to use this tool versus alternatives (e.g., bgg_search to find IDs first, or bgg_game_reviews for reviews). No when-not-to-use guidance is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full responsibility. It only states the basic function but does not disclose behavioral traits such as authentication requirements, rate limits, pagination, or whether it returns all games or just a subset. The minimal information leaves significant gaps for the agent.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with 14 words, front-loading the verb and resource. Every word is informative and there is no redundancy or unnecessary detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (2 parameters, one required) and no output schema, the description is minimally adequate. It lacks details about the return format or what data the collection contains, but it does cover the essential input semantics. A more complete description would mention the response structure (e.g., list of games with details).

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema provides 100% coverage with descriptions for both parameters. The description adds only minor contextual value by mentioning the three status options, which are already enumerated in the schema. With high schema coverage, the baseline is 3, and the description does not significantly augment the meaning.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get a BGG user's game collection filtered by status', specifying the verb, resource, and scope. It naturally distinguishes from sibling tools like bgg_search (search games) or bgg_game_details (details of a specific game).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the tool is for retrieving a user's game collection, but does not provide explicit guidance on when to use it versus alternatives, nor does it mention when not to use it. No comparison with other BGG tools is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must fully disclose behavioral traits. It mentions the scope (current billing period), but fails to describe whether the operation is read-only, what authentication is needed (beyond the param), or any rate limiting. For a tool with no annotations, this is insufficient.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 13 words, front-loading the action and scope. No filler or redundant information. Every word contributes to the purpose, making it highly efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one required parameter, no output schema, no nested objects), the description is adequately minimal. However, it lacks details about the response format or how to interpret the quota information, which would be helpful for an agent to use the result correctly. It meets the minimum viable standard but leaves gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% for the single parameter (auth_key). The description adds no extra meaning beyond the schema's 'DeepL Auth Key'. Baseline score of 3 is appropriate as the schema already documents the parameter, and the description does not provide additional context or format details.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action: 'Get DeepL API usage and quota information'. It specifies the scope 'for the current billing period', which distinguishes it from sibling tools like deepl_list_languages or deepl_translate_text. The verb 'Get' and resource 'usage and quota information' are specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Usage context is implied but not explicit. The description indicates when to use the tool (to retrieve usage/quota info), but does not specify when not to use it or mention alternative tools. No explicit guidance on prerequisites or common scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the burden. It describes a read-only operation ('Get metadata') with no mention of side effects, authentication requirements, rate limits, or response structure. The description is adequate for a simple get, but lacks depth.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, front-loaded with the core action and resource, and contains no unnecessary words. Every word earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the low complexity (single object retrieval), the description is mostly adequate. However, the absence of an output schema means the agent does not know what fields are included in 'metadata.' For a simple tool, this is acceptable but not comprehensive.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 33% (only 'with_settings' is described). The description does not add meaning beyond the parameter names; 'api_key' and 'voice_id' are not elaborated. Since parameter names are self-explanatory, the description adds minimal value, and baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Get metadata for a specific ElevenLabs voice by ID,' clearly identifying the action (get), resource (metadata for a voice), and identification method (by ID). It distinguishes from sibling tools like 'elevenlabs_list_voices' which likely returns all voices, but does not explicitly contrast them.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when a voice_id is available and metadata is needed, but it does not specify when to use this tool versus alternatives (e.g., 'elevenlabs_list_voices' for listing all voices) or provide prerequisites or exclusion criteria.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It only states 'Get current NFL scores' without explaining what 'current' means (e.g., live, today's games), the return format, or any rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single well-formed sentence with no wasted words. It is appropriately sized for a simple, zero-parameter tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is adequate for a tool with no parameters, but it could benefit from additional context such as the scope of scores (e.g., today's games only) or a note that no parameters are required.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has zero parameters, so schema coverage is trivially 100%. The description adds no parameter information, but none is needed. Baseline for 0 params is 4.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get current NFL scores from ESPN' clearly states the verb (Get), resource (current NFL scores), and source (ESPN). It distinguishes itself from sibling tools like espn_mlb_scores and espn_nba_scores by specifying the league.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. For example, it does not clarify that it returns only live or today's scores, nor does it mention that historical or team-specific data requires different tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It does not disclose what 'details' include, whether the operation is read-only, or any constraints (e.g., rate limits). The agent gets minimal behavioral insight.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence with no redundant information. Every word is necessary, achieving maximum conciseness while conveying the core purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has no output schema and only one parameter. The description is too minimal; it does not hint at the return value structure or provide any usage context beyond the basic purpose. Completeness is lacking.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0% (no parameter descriptions). The description mentions 'by ID' but does not explain the expected format or source of the toilet_id. For a single parameter, more detail would be valuable.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get details') and the resource ('specific public toilet') along with the key parameter ('by ID'). It distinguishes from siblings like 'find_nearest_toilets' which use location-based search.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when a specific toilet ID is known. It does not explicitly mention when not to use or name alternatives, but the sibling 'find_nearest_toilets' serves as a natural alternative for those without an ID.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. The description only says 'interact' and lists actions, all of which are read-only (search_projects, get_project, list_issues, list_mrs, get_user), but it does not explicitly state that the tool does not modify data. It also does not disclose authentication requirements beyond the schema. Behavioral traits like read-only nature are missing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences with no wasted words. It front-loads the main purpose and then adds the self-hosted support detail. Every part is informative and necessary.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has 10 parameters and no output schema. The description only covers the actions but does not describe the expected return format or pagination behavior. For a moderately complex tool, this leaves gaps in understanding what the agent will receive.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description does not add parameter-level information beyond what the schema already provides. It briefly lists actions but does not explain parameter relationships or provide examples beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool interacts with the GitLab REST API and lists specific actions (search projects, get project details, list issues, list merge requests, look up users). It also mentions support for self-hosted instances, which adds specificity and distinguishes it from other tools. The verb 'interact' is broad but the enumerated actions make the purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide explicit guidance on when to use this tool versus alternatives. Since it's the only GitLab tool among siblings, the need is lower, but there is no mention of when not to use it or comparison to other tools. The context is clear enough for a single-tool scenario.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, so the description bears the burden of behavioral disclosure. It implies a read operation by listing platforms and statuses, but does not explicitly state read-only behavior, potential side effects, or limitations such as rate limits or required authentication (though the API key context is given).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, well-structured sentence with no redundant information. It is efficiently front-loaded with the core purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers the basic functionality and context (current API key) but lacks details about the output format (e.g., structure of returned data, pagination). Given the absence of an output schema, more completeness would be helpful but is not critically lacking for a simple list operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% description coverage for the only parameter ('category'). The description does not add any extra meaning beyond the schema; it fails to mention the filtering capability. Baseline score of 3 is appropriate given high schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('list'), the resource ('all available platform connectors in the UnClick Keychain catalog'), and additional context ('with connection status for the current UNCLICK_API_KEY'). It distinguishes the tool from siblings like keychain_connect and keychain_disconnect by focusing on listing and status.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool over alternatives (e.g., keychain_status) or any prerequisites. The description lacks explicit when-to-use and when-not-to-use instructions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavioral traits. It does not state whether the tool is read-only (e.g., does not modify todos) or describe side effects. The agent is left unaware of potential changes to todo states or data, which is a significant gap for a list operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences, front-loading the core functionality and following with a requirement. Every word is useful, and there is no redundancy. It is perfectly concise for the information it conveys.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema and annotations, the description should provide more context, such as return format, pagination, or sorting details. It does not specify what fields are in each todo or how priority is determined. The agent cannot fully understand what to expect from the tool's response.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is only 33% (only 'include_description' has a description). The description only restates that 'agent_id' is required, adding no new meaning beyond the schema. The purposes of 'limit' and 'include_description' are not explained in the description, leaving the agent to infer from incomplete schema documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it returns 'highest-priority unassigned open todos, ranked', specifying the verb (returns), resource (todos), and scope (highest-priority, unassigned, open). This distinguishes it from sibling tools like 'list_todos' which likely provide all todos without prioritization or assignment filtering.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies this tool is for retrieving the next actionable todo for an agent without prose handoffs. However, it does not explicitly state when to avoid this tool or mention alternatives like 'list_todos' for a general list. The context is clear but lacks exclusionary guidance.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so description must carry the burden of behavioral disclosure. It mentions sorting by score and optional filtering, but does not disclose pagination, return format, or the existence of the limit parameter. The description is minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, front-loaded with purpose, then optional filter, then required param. No wasted words. Efficient and clear.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the low complexity (3 params, no output schema), the description is partially complete. It covers the main functionality but omits limit parameter and return format. With no output schema, more detail on return values would be expected.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 0%, so description must compensate. It explains agent_id (required) and status (filter), but does not mention limit parameter at all. For a 3-param tool, it covers 2 out of 3, adding some value beyond schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states what it does: returns ideas for the tenant, sorted by score (upvotes minus downvotes) descending, with optional status filter. It distinguishes from sibling tools like create_idea and update_idea by being the listing operation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Description provides context: agent_id is required, and status filter is optional. However, it does not explicitly state when to use this tool versus alternatives like list_actionable_todos or search_ideas (if exists).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. It only states 'Get details' – no mention of authorization needs, rate limits, side effects, or what 'details' entails. Minimal behavioral disclosure.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no wasted words. Front-loaded with verb and resource. Efficiently conveys core purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, so description should hint at return fields. It says 'details' which is vague. With sibling context, it's adequate for a simple retrieval but lacks specifics on what data is returned.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, baseline 3. Description adds 'by ID' which reinforces campaign_id's role, but schema already describes it as 'Campaign ID'. No additional semantic value beyond schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'Get details for a specific Mailchimp campaign by ID', using specific verb+resource+method of identification. This distinguishes it from siblings like 'mailchimp_list_campaigns' (list) and 'mailchimp_create_campaign' (create).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use vs alternatives. The implied usage is when you have a specific campaign ID, but it doesn't contrast with listing or searching. Sibling tools exist but no exclusion criteria provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden. It only states 'check the status' without detailing what statuses exist, whether the call is idempotent, rate limits, or what the response includes. This is insufficient for an agent to fully understand behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. It is front-loaded and to the point, making it easy for an agent to parse quickly.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple polling tool with no output schema, the description is minimally complete. However, it could mention the type of response (e.g., returns status string and optional video URL) to aid agent understanding. No key information is missing, but context is sparse.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema already provides clear descriptions for both api_key and generation_id (generation_id 'returned by pika_generate_video'). The description adds no extra meaning beyond the schema, so it meets the baseline but does not exceed it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('check the status') and the resource ('a Pika video generation by ID'). It distinguishes itself from sibling tools like pika_generate_video (creates) and pika_list_styles (lists styles), making the purpose specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage after generating a video (via generation_id from pika_generate_video), but does not explicitly state when to use this tool vs alternatives, nor provide guidance on polling frequency or fallback behavior. The guidance is implicit, not explicit.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must convey behavioral traits. It implies a read-only operation but doesn't explicitly state safety (non-destructive) or disclose side effects, rate limits, or what the response contains beyond 'nearest-neighbor vectors'. This is adequate but lacks depth.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that immediately conveys the purpose. Every word is necessary, and there is no redundancy or fluff.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 8 parameters and no output schema, the description should provide more context about expected behavior and return values. It only mentions 'nearest-neighbor vectors', which hints at the result but doesn't specify the structure (e.g., matches with scores, metadata). It is partially complete but leaves gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description adds no extra meaning beyond the schema; it does not explain parameter relationships, defaults, or usage nuances. It is acceptable but not helpful beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Query a Pinecone index for nearest-neighbor vectors' clearly states the verb 'query', the resource 'Pinecone index', and the specific action 'nearest-neighbor vectors'. It effectively distinguishes from sibling tools like pinecone_upsert_vectors (write) and pinecone_describe_index (metadata).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as pinecone_query_vectors or other vector search tools. There are no statements about prerequisites, context, or when not to use it, leaving the agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden. It discloses that the tool performs no execution or source-of-truth writes, which is valuable. However, it does not detail other aspects like idempotency, caching, or response format. The transparency is adequate but not comprehensive.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences long, front-loaded with the core purpose, and contains no redundant information. Every word earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a no-parameter, no-output-schema tool, the description covers what it returns, its role in the pipeline, and its limitations. It is sufficiently complete for an agent to understand the tool's function.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The tool has 0 parameters with 100% schema coverage, so the description does not need to add parameter details. Baseline 4 is appropriate as the description adds no param info but the schema already covers all.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states that the tool returns guardrails for the PushOnlyAPI, specifying that it turns IgniteOnly wake packets into push envelopes without execution or writes. The purpose is distinct from siblings like pushonly_api or pushonly_wake_pusher, though some jargon may reduce clarity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like igniteonly_policy or nudgeonly_policy. It does not mention prerequisites, context, or conditions for use, leaving the agent without explicit decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It only says it 'validates' and 'lists devices,' without indicating side effects, permissions, rate limits, or whether it is read-only. This leaves the agent uncertain about mutability.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is one sentence with 12 words, front-loading the main action ('Validate a Pushover user or group key') and adding a clear outcome. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers the core functionality but lacks details on return format, error handling, or how to obtain the app token. For a simple 3-param tool, it is adequate but not complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 33% (only 'device' has a description). The description adds context that the tool validates keys and lists devices, but does not explain 'app_token' or 'user_key' beyond what the name implies. It partially compensates for low coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: to validate a Pushover user or group key and list their registered devices. It uses a specific verb (validate) and resource (user/group key, devices), and the name and sibling tools (e.g., pushover_send_notification) make it distinct.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the tool is for validation, but it does not explicitly state when to use it vs. alternatives (like pushover_send_notification). No exclusions or prerequisites are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. Mentions async behavior (returns task_id to poll), but lacks details on rate limits, cost, or potential destruction.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, no fluff, front-loaded with action verb and resource. Every sentence adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a complex tool with 7 parameters and no output schema, description is functional but lacks details on output structure, model trade-offs, and polling mechanics.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline 3. Description adds context about modes (text-to-video vs image-to-video) but does not add meaning beyond schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states it generates video from text or image using Runway ML, and mentions two modes. Platform name helps differentiate from other video tools, but no explicit sibling differentiation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    States supports text-to-video and image-to-video, implying parameter usage. No explicit when-not-to-use, alternatives, or prerequisites beyond the schema.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must cover behavioral traits. It mentions return values but does not disclose important details such as polling frequency, error handling, rate limits, or the nature of the 'progress' field.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (two sentences) and front-loaded with the core purpose. Every sentence adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 2 parameters and no output schema, the description provides a basic understanding of return values. However, it lacks details on response structure (e.g., format of progress, potential error states) and is not fully complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers both parameters with descriptions. The description adds no extra meaning beyond stating the tool's purpose. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Check' and the resource 'status of a Runway ML generation task'. It mentions what is returned (status, progress, video URL). This distinguishes it from sibling tools like runway_generate_video and runway_list_models.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage after generating a video, but it does not explicitly state when to use this tool versus alternatives (e.g., when to poll) or provide guidance on when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden. It correctly implies a read operation and specifies the returned information (settings and enabled state), but it does not disclose authorization needs (api_key is in schema), potential errors, or rate limits. The description is adequate but not thorough.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single 12-word sentence that is front-loaded and precise. Every word is necessary, and there is no extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with no output schema, the description hints at the response content (settings, enabled state) but does not detail the structure or fields. While functional, it could provide more completeness given the absence of an output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema itself documents both parameters. The description adds no additional meaning beyond the schema, such as format or constraints. Baseline 3 is appropriate given high schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'single Segment source', specifying that it includes 'settings and enabled state'. It effectively distinguishes from sibling tools like segment_list_sources (which lists multiple sources) and segment_identify_user (which identifies users).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. For example, it doesn't mention that segment_list_sources should be used to list all sources first, nor does it indicate prerequisites or scenarios. This lack of context leaves the agent uncertain about appropriate usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavioral traits. It only states that no API key is required, but does not mention any other behaviors such as rate limits, default max value, return format, or error handling. This is insufficient for a tool with no annotation support.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 10 words, efficiently communicating the tool's purpose and a key trait (no API key). It is appropriately front-loaded with the action. Every word earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple search tool with two parameters and no output schema, the description covers the core purpose and a major usage constraint (no API key). However, it omits information about default max value, whether results are paginated, and what the response looks like. While the tool is simple, these details would improve completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema already has descriptions for both parameters (100% coverage). The tool description adds only the phrase 'by name', which reinforces the 'name' parameter but does not add new semantic information. For the 'max' parameter, no additional context like default or range is provided. So the description adds minimal value over the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'Search' and resource 'games on Speedrun.com', and specifies the search criterion 'by name'. This clearly differentiates from sibling tools like speedrun_get_game (which retrieves a specific game) and speedrun_list_runs (which lists runs).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description mentions 'No API key required', which is a useful note for selecting this tool over others that might require authentication. However, it does not explicitly state when to use this tool versus alternatives like speedrun_get_game or speedrun_get_user, missing guidance on when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden of behavioral disclosure. It describes the tool as a read operation, but does not explicitly state that it is non-destructive, has no side effects, or any rate limits or data freshness constraints. For a status check tool, this lack of safety disclosure is a notable gap.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 12 words, front-loaded with the verb 'Fetch' and the resource. Every word is necessary and contributes to clarity. No redundancy or filler.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description lists the data returned (status, verdict summary, fail count) but does not specify the format or structure of the response (e.g., JSON fields). Given the lack of an output schema and annotations, a brief description of the return structure would improve completeness. As is, it is adequate but has a clear gap.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%; the single parameter 'run_id' is well-described in the schema as 'The TestPass run id returned by testpass_run'. The tool description adds no additional meaning beyond what the schema already provides, so the baseline score of 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Fetch) and the resource (current status, verdict summary, fail count for a TestPass run). It distinguishes 'testpass_status' from siblings like 'testpass_run' (which initiates a run) and 'testpass_report_*' (which generate formal reports), making the tool's role unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage after a TestPass run (since it fetches status and results), but it does not explicitly state when to use this tool versus alternatives like 'testpass_report_html' or 'testpass_run'. No guidance on prerequisites or exclusions is provided, leaving the agent to infer context from the tool name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. Description does not disclose any behavioral traits such as rate limits, caching, or whether all categories are returned at once. As a read operation, it should at least indicate no side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence efficiently conveys purpose. Front-loaded with 'Get' and resource. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no parameters and no output schema, the description is minimally adequate. However, without output schema details, the agent cannot anticipate the structure of the returned categories (e.g., array of strings or objects). Adding a note about the return format would complete the picture.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    No parameters exist, and schema coverage is 100% (trivial). The description adds no parameter info but none is needed. Baseline for 0 parameters is 4.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the action 'Get' and resource 'available trivia categories' from a specific source 'Open Trivia DB'. It is distinct from sibling tool 'trivia_questions' which would handle questions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. Does not mention prerequisites or that it should be called before trivia_questions. For simple tools, some context like 'use this to list categories before fetching questions' would help.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must convey behavioral traits. It only states 'Get' which implies a read operation, but it does not disclose whether the tool has side effects, requires specific authentication, or what happens on invalid run_id. Minimal transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of seven words, concise and front-loaded with the key information: what it does and for what context. No redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers the basic purpose and required input, but it lacks context about the relationship to sibling tools (e.g., uxpass_run), error handling, or output format. Given no output schema, some guidance on the return structure would improve completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with an adequate description of run_id. The tool description adds no new meaning beyond the schema; it merely repeats the purpose. Baseline of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'JSON report', and the context 'for a UXPass run', distinguishing it from sibling report tools that output other formats like HTML or Markdown.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives (e.g., uxpass_report_html, uxpass_report_md). Usage is implied but not clarified, leaving the agent to infer from the description alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description offers no behavioral details such as whether the report is cached, requires authentication, or has any side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words, front-loading the purpose effectively.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one parameter and no output schema, the description is minimally adequate but could explain what the Markdown report contains or how to interpret it.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and the parameter description is adequate. The tool description adds no additional meaning beyond what the schema provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get the Markdown report') and the resource ('for a UXPass run'), with 'Markdown' differentiating it from sibling tools that return HTML or JSON reports.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies this tool is for retrieving the Markdown version of a UXPass report, but does not explicitly say when to choose Markdown over HTML or JSON reports.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the full burden. It does not state that the operation is read-only, idempotent, or that it has no side effects. Basic fetch behavior is implied but not explicitly disclosed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, front-loaded with the purpose, and contains no redundant information. Every word is necessary.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple status tool with one parameter and no output schema, the description is adequate but lacks context on what 'status' or 'summary' entails. It does not explain the format or range of the UX Score.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, and the description adds no new information beyond the schema's parameter description. Both say the run_id is returned by uxpass_run, which is sufficient but offers no extra detail.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool fetches the status, UX Score, and summary for a UXPass run, specifying the action (Fetch) and the resource (UXPass run). It distinguishes from siblings like uxpass_run (initiates) and uxpass_report_* (generates reports).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Usage is implied as checking the status after running uxpass_run, but no explicit when-to-use or when-not-to-use guidance is given. Alternatives like reports are mentioned in sibling list but not compared.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided. The description 'Get the ISO week number' implies a read-only operation with no side effects, but does not disclose any potential errors, permissions, or other behavioral details.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence that conveys the essential purpose without extraneous text.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one parameter, the description covers the basic purpose but fails to specify the return value format or param constraints, which are needed for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has no description for the 'date' parameter (0% coverage). The description does not specify the expected date format (e.g., YYYY-MM-DD), leaving the agent to infer from the parameter name.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the specific resource 'ISO week number for a date', which is distinct among sibling datetime tools like datetime_date_diff and datetime_business_days.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternative datetime tools. The purpose implies usage for week number calculations, but lacks differentiation from siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are present, and the description does not disclose behavioral traits such as whether results are live, cached, or require authentication, nor does it explain the response format or if it covers multiple games.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no redundancy. Though very brief, it conveys the core purpose efficiently for a simple tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a parameterless tool with no output schema, the description is minimally adequate but lacks details such as the scope (e.g., all games today, live scores) and whether it reflects real-time updates.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With zero parameters, the baseline is 4. The description adds no parameter-specific meaning, but none is needed as there are no inputs to describe.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets 'current NHL scores from ESPN.' It specifies the verb (Get), resource (current NHL scores), and source (ESPN), distinguishing it from sibling tools like espn_mlb_scores or espn_nba_scores.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit when-to-use or when-not-to-use guidance is provided. While the tool name implies NHL usage, the description lacks direction on alternatives or context compared to other ESPN sports tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden. It discloses that an API key is required, which is a critical behavioral trait. However, it does not mention other traits like rate limits, error handling for invalid dates, or that it is a read-only operation (though implied). The disclosure is adequate but not comprehensive.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (two sentences), front-loaded with the purpose first, and every sentence earns its place. No extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given that there is no output schema and no annotations, the description is insufficiently complete. It does not explain the returned data format, valid date ranges, or the role of the optional 'base' parameter (though the schema states default USD). For a tool with 5 parameters and no output schema, the description should provide more context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% coverage with descriptions for all 5 parameters. The description adds no additional meaning beyond what the schema already provides, so a baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Get historical exchange rates for a specific date.' This distinguishes it from sibling tools like exchangerate_latest (current rates) and exchangerate_convert (conversion). The verb 'get' and resource 'historical exchange rates' are specific.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies that the tool should be used when historical rates for a past date are needed, but it does not explicitly exclude other use cases or mention alternatives (e.g., 'use exchangerate_latest for current rates'). The context is clear but lacks explicit when-not guidance.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must disclose behavioral traits. It implies a read operation but does not confirm safety, authentication needs, error handling for invalid run_id, or rate limits. This is insufficient for safe agentic use.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences: first specifies when to use, second details return content. No wasted words, front-loaded purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple single-parameter tool without output schema, the description covers purpose and return content adequately. Missing details like error responses, but overall sufficient given tool complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with the run_id parameter fully described as 'The run_id returned by start_crew_run'. The description adds no extra meaning beyond this; baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves the status of a specific Crews run and lists what the response contains (stage progress, token usage, failure artifact). This differentiates it from siblings like start_crew_run (which initiates runs) and list_runs (which lists runs).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description tells when to call the tool but does not contrast it with alternatives like list_runs for retrieving status of multiple runs or start_crew_run for initiating. Without explicit guidance, an agent may misselect among related tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, rate limits, data freshness, or error handling. It only lists return content.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that conveys the core purpose without extraneous words. While concise, it could benefit from a structured list of return fields.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with no output schema, the description covers the basic purpose and return types. However, it lacks details on error behavior, data sources, and what happens for invalid app IDs.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with clear parameter descriptions. The tool description adds context by explaining the type of data returned (game info, price, platforms, Metacritic), which helps infer the role of optional parameters like cc and l.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'Steam app', and lists specific details like game info, price, platforms, and Metacritic score. It distinguishes itself from sibling tools like get_steam_achievements and search_steam_store.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not explicitly state when to use this tool versus alternatives like search_steam_store. It implies usage for known app IDs, but lacks explicit guidance or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It states it lists all available avatars but lacks details on pagination, rate limits, or authentication behaviors beyond the required API key. The description is minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that effectively communicates the tool's purpose without any unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with one parameter and no output schema, the description is adequate. It specifies what the tool returns (list of avatars), though it does not detail the response structure, which is acceptable given the tool's simplicity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema covers 100% of parameters with descriptions. The description does not add additional meaning beyond the schema, so it meets the baseline for a tool with complete schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (list) and the resource (all available AI avatars in your HeyGen account). It is specific and distinguishes itself from sibling tools like heygen_list_voices and heygen_create_avatar_video.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide explicit guidance on when to use this tool versus alternatives or any prerequisites. However, the simplicity of the tool and the context of sibling tools make the usage context clear enough.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It discloses the conditional output ('only when safety gates pass') but does not explain side effects, error handling, or authentication needs. Minimal behavioral detail.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two efficient sentences front-load the purpose and condition with no fluff. Every part earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 13 parameters with nested objects and no output schema, the description is insufficient. It lacks explanation of 'safety gates', what constitutes verified input, and output structure. Missing critical context for complex tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description adds little beyond the schema; it mentions 'verified NudgeOnly bridge result' which maps to some parameters, but does not explain parameter interactions or usage context.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool runs IgniteOnly on a verified NudgeOnly bridge result or deterministic evidence, and emits a wake packet only when safety gates pass. This distinguishes it from siblings like nudgeonly_api and pushonly_api.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage on verified evidence with safety gates, but lacks explicit guidance on when not to use it or alternative tools. The condition 'only when safety gates pass' provides some context but no exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It implies a read-only operation but does not explicitly state side effects, authentication requirements, rate limits, or behavior on failure. The context 'for the current UNCLICK_API_KEY' is helpful but incomplete.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, well-structured sentence that front-loads the action. Every word adds value with no redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one optional parameter and no output schema, the description covers the essential purpose and scope. It misses describing the return format or indicating read-only behavior explicitly, but is generally sufficient.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers the parameter description fully (100% coverage). The tool description adds no extra meaning beyond what the schema already provides, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Check the connection status'), the resource ('platform credentials'), and the scope ('one or all'). It distinguishes from sibling tools like keychain_connect and keychain_disconnect, which modify credentials, and keychain_list_platforms, which lists platforms without status.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or scenarios where other keychain tools would be more appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, and the description only mentions 'Check the status' without disclosing behavioral traits such as read-only nature, potential rate limits, or error handling behavior. The description does not add value beyond the basic operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence with no wasted words. It front-loads the purpose and is efficiently structured.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple status check tool with only two parameters and no output schema, the description is largely complete. It could be improved by mentioning the expected return value (e.g., task status), but it is sufficient for basic understanding.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% for both parameters (api_key, task_id), so the description does not need to add more meaning. The baseline of 3 is appropriate since the schema already documents the parameters adequately.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Check' and the resource 'status of a Kling AI video generation task'. It effectively distinguishes itself from the sibling tool 'kling_generate_video', which is the complementary creation tool.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage after submitting a video generation task via the sibling tool 'kling_generate_video', but does not explicitly state when to use this tool, nor does it provide any exclusions or alternative guidance.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries behavioral disclosure. It mentions the return format (ConversationalCard) and included data (run count, newest run IDs). However, it omits details like sorting order (recency is implied), default limit behavior, and filtering options beyond what the schema provides.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences, front-loaded with a usage cue, and contains no unnecessary information. Every sentence serves a clear purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with no output schema, the description adequately covers the return type and content. Minor gap: it does not explicitly mention filtering by crew_id or the limit parameter, though schema provides that. Nested objects and output schema not present, so completeness is reasonable.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with both parameters already well-described in the input schema (crew_id and limit with defaults and caps). The description adds no additional parameter semantics, making the baseline 3 appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the resource ('Crews runs') and action ('list recent history'). While it does not explicitly distinguish from siblings like 'get_run', the naming and context imply differentiation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description tells when to use ('when the user wants a recent history of Crews runs') but provides no guidance on when not to use or mention alternatives (e.g., 'get_run' for a specific run). Usage context is implied, not explicit.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; the description merely states 'Get an author' without disclosing return format, error behavior, or any side effects, leaving the agent underinformed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with no wasted words. Efficiently communicates the tool's core function.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Adequate for a simple retrieval tool with one parameter. However, could mention that it returns the author record to further differentiate from siblings like openlibrary_author_works.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The parameter author_id is described with an example 'e.g. OL23919A', adding value beyond the schema's description. Schema coverage is 100%, so baseline is 3, but the example earns a 4.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', resource 'author', and source 'Open Library', distinguishing it from sibling tools like openlibrary_author_works or openlibrary_get_book.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives (e.g., openlibrary_author_works). No exclusions or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided. The description only mentions the batch limit. It does not disclose error handling (e.g., partial failures), rate limits, required authentication beyond the API key, or what happens if a message fails. This is a significant gap for a batch operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence that front-loads the key purpose and constraints. No unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool sends batches of emails, the agent needs to know error behavior, rate limits, and how to handle failures. The description lacks these details. No output schema or annotations exist to compensate. The description is too minimal for the complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 100% description coverage. The description adds value by stating that the 'messages' array contains objects with 'same fields as send_email', which helps the agent understand the expected structure. However, no further details on the 'api_key' parameter are added beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Send') and resource ('multiple emails in a single Postmark API call') and explicitly states the maximum batch size (500 messages). This clearly distinguishes it from the sibling tool 'postmark_send_email' which sends a single email.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for sending multiple emails in one call, but does not explicitly state when to use this tool versus sending individual emails (e.g., for efficiency, or when you have more than 500 messages). No alternatives or exclusions are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It describes locking the idea and posting an event, but lacks details on error handling, return value, or additional behavioral traits like idempotency or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with four sentences, each adding value. It front-loads the core action and then provides conditions and effects without unnecessary fluff.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description lacks information about the return value (no output schema) and error scenarios. Given no output schema, it should at least hint at what is returned, making it incomplete for a mutation tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, so the description must compensate. It only explains agent_id, leaving idea_id, priority, and assigned_to_agent_id without any semantic context beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it converts an idea to a todo and locks the idea, with specific conditions and side effects. This distinguishes it from siblings like create_todo and create_idea.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    It mentions prerequisite conditions (net upvotes >= 1 or admin caller), providing context for when this tool is appropriate. However, it does not explicitly state when not to use it or compare with alternatives like vote_on_idea.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description provides a key behavioral trait: it never writes source-of-truth state or executes work. However, it does not cover error conditions, side effects, or auth requirements. The description is adequate but could be more comprehensive.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences, each providing distinct value: the first defines the action, the second adds a critical constraint. No superfluous words. Perfectly concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite having 16 optional parameters and no output schema, the description is minimal. It does not explain how to use the parameters, the overall workflow, or how this tool fits with siblings like pushonly_api or igniteonly_api. An agent would likely need more guidance.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All 16 parameters have descriptions in the input schema (100% coverage), so the baseline is 3. The description does not add additional meaning beyond the schema, but it is not required to since the schema is complete.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool consumes a verified IgniteOnly wake packet and emits a PushOnly worker envelope. It also explicitly distinguishes itself by stating it never writes state or executes work, setting it apart from sibling tools that may do so.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the tool should be used when a verified IgniteOnly wake packet is available, but it does not explicitly state when to use it versus alternatives like igniteonly_api or pushonly_api. There is no when-not guidance or mention of prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It discloses basic behavior (listing sources) but does not mention pagination, rate limits, permissions, or error handling. Adequate but minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with verb and resource, no wasted words. Efficient and to the point.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with 100% schema coverage, the description is complete enough. It could mention pagination or response format, but not required. The mention of 'all' provides necessary scope.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for both parameters. The description does not add additional meaning beyond the schema; it simply restates the tool's purpose. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'List all Segment sources in a workspace', providing a specific verb and resource. It distinguishes itself from sibling tools like segment_get_source or segment_list_destinations by focusing on listing all sources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. It does not mention when not to use it (e.g., if filtering is needed) or provide context about prerequisites beyond the required parameters.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries full burden. It clarifies that the tool only builds a plan and does not execute or persist, which is key behavior. However, it does not mention side effects, idempotency, or required permissions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description does not explain what the 'plan' output contains, how it connects to seopass_run, or what the agent receives back. Given no output schema, this omission leaves the tool's integration unclear.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% coverage for parameter descriptions. The tool description adds no additional meaning beyond what the schema already provides, so baseline score applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The name 'seopass_lighthouse_plan' clearly indicates it's a planning step. The description specifies it builds a Lighthouse execution plan for a SEOPass target URL, distinguishing it from sibling tools like seopass_run which handle execution.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies use before execution ('Execution and persistence land in a later chunk') but does not explicitly state when to use it versus alternatives, such as seopass_run.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the burden. It mentions the API but does not disclose authentication requirements (bearer_token), rate limits, or message size limits. The behavioral traits are minimally covered.

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description indicates a read-only operation ('Retrieve'), which is transparent. However, with no annotations provided, it does not disclose other behavioral traits such as rate limits, authentication requirements beyond schema, or any side effects. The schema already covers credential parameters.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence (12 words) that front-loads the purpose and method. No unnecessary words or repetitions.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read operation with all parameters required and no output schema, the description is nearly complete. It covers the what and how. A minor improvement would be mentioning the return format (object), but this is not essential.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with all four parameters described. The description does not add meaning beyond the schema; it only reiterates the 'objectID' parameter. Baseline of 3 is appropriate as the schema carries the full burden.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Retrieve' and the resource 'a single record from an Algolia index', and specifies the method 'by its objectID'. It distinguishes from sibling tools like algolia_search (multiple results) and algolia_browse_index (browse all records).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when a specific objectID is known, but does not explicitly state when to use or avoid this tool, nor does it mention alternative tools like algolia_search for non-objectID lookups or algolia_browse_index for multiple records.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It discloses the output (trend classification and volume data) but lacks details on data freshness, API rate limits, authentication needs, or algorithmic specifics. Basic transparency is present but could be improved.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences with no wasted words. It is front-loaded with the core purpose and output, making it easy to quickly understand.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description lists the trend classification values and mentions volume data. However, it could specify the structure of the volume data (e.g., time series format). Still, it provides sufficient context for an agent to understand what to expect.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and the description does not add meaningful extra context beyond the schema. The schema already documents the query, timespan, and sourcelang parameters adequately.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Check'), the resource ('whether a topic is trending in global news using GDELT article volume timelines'), and the output (trend classification and volume data). It distinguishes from sibling tools like gdelt_geo_events, gdelt_news_search, and gdelt_tone_analysis by focusing specifically on trending topic status.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for checking trending topics but does not explicitly state when to use this tool versus alternatives like gdelt_news_search or gdelt_tone_analysis. No when-not-to-use guidance or prerequisites are provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must cover behavioral traits. It indicates the tool lists all workspaces, but it does not specify authentication requirements (API key is optional in schema, but needed for access), pagination, or error behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with no redundant information. It is front-loaded and concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple and the description covers its purpose. However, since there is no output schema, the description does not specify the return format (e.g., workspace IDs, names). This is a minor gap.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% description coverage for its single parameter (api_key), so the description adds no additional meaning beyond what the schema already provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'list' and the resource 'Asana workspaces', with scope 'accessible by the authenticated user'. It implicitly distinguishes from sibling tools that list projects or tasks.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the tool is for listing workspaces, which is distinct from other Asana tools, but it does not provide explicit guidance on when to use it over alternatives or any conditions for use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description must carry the burden. It clarifies the tool's limitations and routing, but does not describe the return format, potential errors, or behavior beyond the scope restrictions. Basic scope is clear, but deeper behavioral traits are missing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, front-loaded with the core purpose and followed by limitations. No wasted words, all sentences earn their place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite high parameter count and no output schema, the description lacks details about what the tool returns, how the worker processes input, or error handling. The missing behavioral and output information makes it incomplete for a tool with 9 parameters and no output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so parameters are well-documented in the schema. The description does not add new semantic meaning beyond what the schema already provides for each parameter. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states the specific verb 'Run' and resource 'PinballWake NudgeOnlyAPI worker' and explicitly lists what it cannot do, distinguishing it clearly from siblings that might perform state mutations.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    It explicitly says 'Use only for painpoint hints and simple-English nudge summaries' and lists prohibited actions, providing clear context. However, it does not mention specific alternatives or when-not-to-use scenarios beyond the given list.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the burden of behavioral disclosure. It states read-only and safe operation ('no writes, no decisions'), which is helpful, but does not disclose authentication needs, rate limits, or response format. Additional context would improve transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences with no wasted words. It front-loads the core purpose and then adds constraint details efficiently.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite the absence of an output schema, the description does not explain what the returned guardrails look like, their structure, or any metadata. For a tool with no output schema, this omission leaves agents uncertain about the response format.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    No parameters exist, so the schema already fully defines the input. The description does not need to add parameter semantics, earning the baseline score of 4 for parameterless tools.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool returns the PinballWake NudgeOnlyAPI guardrails, specifying it is a red-lane, read-only policy. The verb 'Return' and resource 'guardrails' are specific. The mention of 'no writes, no decisions, no truth-setting' distinguishes it from write-capable policies like pushonly_policy.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not explicitly state when to use this tool versus other policy tools like pushonly_policy or igniteonly_policy. It implies read-only usage but lacks comparative guidance or prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the burden of behavioral disclosure. The description implies a read-only list operation, but does not mention rate limits, authentication requirements beyond the API key, or output format. It is minimally adequate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with zero wasted words. It is appropriately brief for a simple listing tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity and lack of output schema, the description adequately states the tool's purpose. However, it could mention the expected output (e.g., a list of index names) for completeness. Still, it is sufficient for a list operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 100% description coverage for the single parameter (api_key). The description does not add any new meaning beyond what is already in the schema, so baseline score of 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (List), the resource (Pinecone vector indexes), and the scope (in the project). It is specific and distinguishes from sibling Pinecone tools which handle individual index operations.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide guidance on when to use this tool versus alternatives like pinecone_describe_index or pinecone_query_vectors. While the purpose is straightforward, explicit context is missing.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description partially discloses behavior by listing included statistics. However, it omits important details like authentication requirements, rate limits, data freshness, or that it is a read-only operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one parameter, no output schema, no nested objects), the description provides sufficient context about what the tool returns. It could note time range or aggregation but is adequate for straightforward stats retrieval.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with one parameter (api_key) described as 'Postmark server token'. The description adds no additional parameter meaning, so baseline 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves delivery statistics from Postmark, listing specific examples like bounces, spam complaints, and open rates. It distinctly differs from sibling tools (e.g., postmark_send_email, postmark_search_messages) which handle other Postmark functions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when delivery stats are needed, but does not provide explicit when-to-use guidance, prerequisites, or comparisons to alternatives. Minimal guidance is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description must disclose behavioral traits. It only describes what to include, not whether saves overwrite, require permissions, or return values. No mention of side effects or safety considerations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Well-structured with front-loaded purpose, detailed usage triggers, and clear exclusions. Slightly verbose but each sentence adds value for the agent's decision-making.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema or annotations; the description should cover return values and error handling. It only covers usage context, missing behavioral details like return format or idempotency.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with good parameter descriptions. The description adds minimal extra meaning (e.g., suggesting content types) but does not provide examples or formats beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool saves a structured summary of the current session for resumption, with a specific verb ('saves') and resource ('structured summary of the current session'). It implicitly differentiates from sibling tools like 'save_conversation_turn' by focusing on session-level summaries.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Extensive when-to-use guidance is provided, including trigger phrases, mid-session checkpoints, and explicit exclusions for trivial exchanges. This tells the agent exactly when to invoke the tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden. It discloses that sending a template message is a write operation and adds the behavioral constraint about timing. However, it does not mention error cases (e.g., template not approved), rate limits, or authentication details beyond the required parameters.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 16 words, front-loading the purpose and the critical condition. Every word is essential, and there is no redundant information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 6 parameters and no output schema or annotations, the description adequately explains the core use case and when to invoke it. However, it lacks details on return values, error handling, and where to find template names, which would be needed for full autonomous invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 6 parameters with only 33% description coverage. The description adds no parameter-specific information beyond what is in the schema. For example, it does not explain 'bearer_token', 'phone_number_id', 'to', 'template_name', or 'components'. This low coverage combined with no added parameter meaning results in a score of 2.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Send), the resource (WhatsApp template message), and crucially adds the condition 'required for first contact or >24h since last message', which distinguishes it from other WhatsApp sending tools like whatsapp_send_text.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explicitly specifies when this tool is required (first contact or >24h since last message), providing clear context for the agent to decide when to use it over alternatives. It does not list exclusions or alternatives explicitly, but the condition implicitly covers when not to use other tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Without annotations, the description provides good behavioral details: sets status, stamps completed_at, posts event, and notes agent_id required. This covers the mutation and side effects adequately.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three sentences front-load the purpose with no wasted words. Efficient and clear.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema or annotations, the description covers the effect and required input adequately. Slight gap: what agent_id refers to is not explained, but the tool name and context make it reasonable.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0% and the description only mentions agent_id is required without explaining what the parameters represent or any format constraints. For a 2-param tool, this adds minimal value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action: 'marking a todo as done' with specific details on what it does (set status, stamp timestamp, post event). It distinguishes itself from sibling tools like create_todo, update_todo, delete_todo.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies it's a 'shortcut' but does not explicitly explain when to use this vs. alternatives like update_todo. No guidance on when-not or prerequisites beyond agent_id requirement.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden. It discloses key behavior: 'Soft state, not a delete.' However, it lacks details on side effects, reversibility, or impact on related data. Adequate but not rich.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three sentences, each essential: first defines action, second clarifies state, third provides usage context and required parameter. No fluff, well front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and only 2 required params, the description covers purpose, state nature, usage context, and a required param. It does not describe response or state change details, but given simplicity, it is mostly complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage for parameters. The description only mentions 'agent_id required', which is already in the schema. It adds no explanation for todo_id or what agent_id specifically means, providing minimal additional value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Marks a todo as dropped'), the resource ('todo'), and distinguishes it from deletion with 'Soft state, not a delete'. This differentiates it from the sibling tool 'delete_todo'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description gives contextual guidance: 'Use when a todo is obsolete but the history still matters.' It implies when to use but does not explicitly state when not to use or name an alternative tool, though the sibling 'delete_todo' is implied.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It discloses that it uses the free tier and works without an API key, but it does not discuss rate limits, authentication requirements, or any potential side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description consists of two concise sentences with no wasted words, effectively communicating the core functionality and key usage note.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of an output schema, the description could hint at the response structure (e.g., rates for all currencies or just a subset) or mention supported currencies. It covers the basics but leaves some ambiguity about what exactly is returned.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema already documents parameters. The description adds no additional meaning beyond 'works without API key' for the api_key parameter, which is already implied by the schema's optional nature.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get latest currency exchange rates for a base currency,' specifying the verb, resource, and scope. It is distinct from sibling tools like exchangerate_historical and exchangerate_convert.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    It mentions it works without an API key using the free tier, providing clear context for when to use it. However, it does not explicitly mention when not to use it or suggest alternatives for different needs (e.g., historical rates).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description must carry the full burden. It mentions returning status and video URL, but does not disclose potential behavior like polling, error handling, or rate limits. Adds basic context but lacks depth.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with two sentences, front-loading the purpose and return value. No extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    There is no output schema, so the description must explain return values. It minimally states returns status and video URL, but does not describe possible status values or that video URL is conditional. Adequate for a simple check but could be more complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with both parameters documented. The description adds no additional meaning beyond the schema, so baseline score of 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Check the status') and the resource ('a Higgsfield AI generation by ID'), and specifies what is returned ('status, video URL when complete'). It distinguishes from sibling tools like higgsfield_generate_video and higgsfield_generate_image.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage after a generation is initiated, but does not explicitly state when not to use it or mention alternatives. However, for a status check tool, the context is clear enough.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description effectively discloses key behaviors: encrypted storage, credential testing, and caller scoping. It adds value beyond the schema, though it could mention error handling on test failure or existing credential conflicts.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three concise sentences, no fluff, front-loaded with the main action. Every sentence adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description lacks information on return values or success/failure indicators. It also does not address idempotency or conflict when a credential already exists. Adequate but incomplete for a write operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description repeats schema details for platform, credential, and label without adding new semantic information beyond the schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool stores an encrypted credential and tests it before saving, specifying the resource ('platform credential') and action. It differentiates from sibling tools like keychain_secure_connect by mentioning testing and scoping.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies use when storing a platform credential but does not provide explicit guidance on when to use this tool versus alternatives like keychain_secure_connect, nor does it state when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, and the description does not disclose any behavioral traits such as authentication requirements, rate limits, or side effects. However, as a simple read operation, the lack of detail is minimally acceptable.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single concise sentence with no unnecessary words. Every element earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple single-parameter get operation, the description is adequate but lacks details about the returned profile structure, especially given the absence of an output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% for user_id, and the description restates the schema's description ('User ID or username') without adding new semantic meaning. Baseline score applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get'), the resource ('Speedrun.com user profile'), and the lookup mechanism ('by ID or username'). It distinguishes well from sibling tools like speedrun_get_game or speedrun_search_games.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies when to use this tool (when a user profile is needed), but provides no explicit guidance on alternatives or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations exist, so the description carries the full burden. It states the updatable fields and requires agent_id for attribution, but does not disclose behavior like idempotency, error handling, permissions, or return value. The mention of possible statuses adds some behavioral context, but significant gaps remain.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is three sentences, front-loaded with the core action, followed by usage guidance and a required parameter note. No redundancy or fluff; every sentence adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and 7 parameters, the description covers purpose and usage but omits return value format, prerequisites (e.g., existing todo?), and error conditions. The required agent_id is mentioned, but overall completeness is only adequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With only 43% schema description coverage, the description helps by listing the updatable fields and providing examples (kanban statuses, unassign). However, it does not describe each parameter individually beyond the schema, and the schema already covers agent_id, todo_id, and assigned_to_agent_id. Partial compensation for low coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Update' and the resource 'todo', and lists specific fields (title, description, priority, status, assignee). It distinguishes from siblings like create_todo or complete_todo by specifying what can be updated and when to use (scope changes, ownership shifts, kanban moves).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides explicit usage scenarios: scope changes, ownership shifts, moving between kanban columns. It also lists the valid status values. However, it does not explicitly contrast with alternative tools like complete_todo, leaving some ambiguity.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. It discloses mutation behavior, caching behavior (force_new), and conditions requiring cache skip. But it doesn't address authentication, rate limits, or side effects like overwriting existing deployments.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, zero waste. First sentence states purpose, second explains parameters and usage. Efficient and front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Covers core use cases (redeploy, fresh deploy, cache skip) but lacks explanation for less common parameters (name, team_id, api_key) and no output schema or prerequisites. Adequate but not exhaustive for a tool with 8 params and no annotations.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 63%; description adds meaning for key parameters (deployment_id, project_id, git_ref, force_new) by explaining their roles in redeploy vs fresh deploy. However, 3 params (name, team_id, api_key) have no description in either schema or description.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description explicitly states it's for creating a Vercel deployment, with two distinct modes (redeploy with deployment_id, fresh deploy with project_id+git_ref), clearly distinguishing from sibling Vercel tools which handle env vars, listing, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Provides clear context on when to use each mode and when to set force_new=true (e.g., after env var changes). However, it doesn't explicitly state when NOT to use this tool or suggest alternatives beyond the described modes.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It mentions 'upsert' behavior and target defaults, but does not disclose authentication requirements, rate limits, or side effects beyond the upsert.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences with no filler. The first sentence delivers the core purpose, and the second adds essential usage detail. Every sentence earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite 10 parameters, no annotations, and no output schema, the description covers the main action and two key parameters but omits guidance on authentication (api_key), team_id, git_branch, comment, or return value. Feels adequate but not comprehensive.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is low (30%). The description adds value by clarifying when to use 'plain' vs 'encrypted'/'sensitive' and stating default targets, partially compensating for the lack of schema descriptions. Other parameters remain undocumented in both schema and description.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Create (or upsert) an environment variable on a Vercel project', using a specific verb and resource. It distinguishes from sibling tools like vercel_delete_env and vercel_get_env by focusing on creation/upsert.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides useful guidance on default targets and type semantics (plain vs encrypted/sensitive). However, it does not explicitly contrast with alternatives (e.g., vercel_get_env for reading, vercel_delete_env for deletion).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. Discloses side effect ('Posts an 'idea-created' Boardroom event'). Does not mention permissions, rate limits, or destructive behavior. Adequate but minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences plus a clause, all front-loaded. No wasted words. Each sentence adds distinct value: action, usage, side effect, required parameter.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple creation tool with 3 parameters and no output schema, description covers purpose, usage, side effect, and required parameter. Does not explain return value or behavior on duplicates, but sufficient for typical use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 67% (agent_id missing description). Description adds that agent_id is required (already in schema) and notes description is optional with max 4000 chars. Does not explain agent_id's meaning beyond 'required'. Adds marginal value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states action ('Drops a new idea into the Boardroom Ideas board') and purpose ('so the pack can react and vote'). Distinguishes from todo tools by specifying 'Use when something is too speculative for a todo but worth capturing.' Differentiates from siblings like create_todo and promote_idea_to_todo.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Provides explicit when-to-use guidance ('too speculative for a todo'). Implies alternative (create_todo). States required parameter ('agent_id required'). Does not list exclusions or when not to use, but overall clear.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. It mentions posting a 'todo-created' Boardroom event, which is a useful behavioral side effect. However, it omits details on failure cases, authorization, or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three sentences, front-loaded with the core action, no redundant information. Each sentence adds value: purpose, usage guidance, and behavioral note.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a creation tool with 5 parameters (2 required) and no output schema, the description covers purpose, usage scenario, and a key side effect (event posting). It could mention return value, but not required without schema. Adequate overall.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 80% (4 out of 5 parameters have descriptions). The description restates parameter names ('agent_id, title, optional description, priority, assignee') without adding new meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Creates a new todo card on the Boardroom Todos kanban', specifying the verb and resource. It distinguishes from sibling tools like complete_todo and delete_todo by mentioning the kanban and cross-visibility for agent and human.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly states when to use: 'Use when you decide an action item needs tracking beyond a single message'. While it doesn't list exclusions or alternatives, the context is clear given sibling tool names.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It correctly implies a read-only query and describes the return content, but does not mention pagination, rate limits, or data freshness. The behavior is adequately transparent for a simple data fetch tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, front-loaded with the core action and followed by output details. Every sentence earns its place with no extraneous words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 3 parameters, no output schema, and no annotations, the description provides sufficient context about purpose and return fields. It could be more precise about data format (e.g., tone score range), but is adequate for tool selection.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, with clear descriptions for each parameter. The description adds meaning by specifying the output structure (clusters with location, article count, tone score) beyond the schema, which has no output schema defined.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get geographic distribution', the resource 'news events for a topic from the GDELT GEO API', and the return shape 'event clusters with location, article count, and tone score'. It distinguishes from sibling tools like gdelt_news_search and gdelt_tone_analysis.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for geographic mapping of events but does not provide explicit guidance on when to use it versus alternatives. It lacks when-not-to-use conditions or direct sibling references.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It discloses that the tool returns 'average tone scores (negative = negative coverage, positive = positive), trend summary, and timeline,' which describes the output behavior. However, it lacks details on data source, limitations, or whether it is read-only. This is adequate but minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences long, front-loaded with the core purpose and output, followed by a use case. Every sentence earns its place; there is no wasted text.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity and lack of output schema, the description adequately explains the return values (tone scores, trend summary, timeline). It could be improved by mentioning the output format (e.g., JSON) or data scope, but it is essentially complete for an agent to understand what the tool does.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema covers all four parameters with descriptions (100% coverage), so the baseline is 3. The tool description adds no extra meaning beyond suggesting the 'query' is a topic. It does not elaborate on the timespan, sourcelang, or sourcecountry parameters, so no additional value is provided.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Analyse the sentiment and tone of global news coverage for a topic over time.' It specifies the verb (analyse), resource (global news coverage), and output (average tone scores, trend summary, timeline). This distinguishes it from sibling GDELT tools like gdelt_geo_events and gdelt_news_search, which focus on different aspects.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides usage context: 'Great for brand monitoring or tracking public sentiment.' This implies when to use the tool. However, it does not explicitly mention alternative tools or state when not to use it, which would be helpful given the sibling GDELT tools. Still, the guidance is clear enough.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden. It discloses that the tool returns guardrails and specifies constraints (verified worker wake packets only, and disallows certain operations), but omits details on side effects, authentication requirements, or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise with two sentences, front-loading the action and resource, and wastes no words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given zero parameters and no output schema, the description adequately explains the return value (guardrails) and their nature. It could specify the output format (e.g., JSON), but this is not critical.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The tool has zero parameters, and schema coverage is 100% trivially. The description adds no parameter information, but for zero-parameter tools the baseline score is 4.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses the specific verb 'Return' and identifies the resource as 'PinballWake IgniteOnlyAPI guardrails'. It distinguishes itself from the sibling 'NudgeOnly' by specifying what is included (verified worker wake packets only) and excluded (no build, merge, approval, closure, or truth-setting).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage context by labeling this as the 'green ignite sibling' to NudgeOnly, but it does not explicitly state when to use this tool versus alternatives or provide any exclusions or prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the full burden. It states that the tool does not persist results and returns a plan (crawl and Lighthouse execution plan). This discloses key behavior, but lacks details on side effects, permissions, or rate limits. The description is adequate but not comprehensive.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with two sentences: the first states purpose, the second adds behavioral detail. It is front-loaded and every sentence adds value. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of output schema, the description provides adequate context: it returns a plan. It mentions 'Chunk 1' which implies a multi-step process but does not explain further. The description helps differentiate from other Pass tools by specifying SEOPass and crawl/Lighthouse. It is mostly complete for a planning tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the baseline is 3. The description does not add new meaning beyond what the schema already provides for 'url' and 'pack_name'. It effectively ties parameters to the planning context but adds no additional detail.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Plan a SEOPass run against a URL or registered pack.' It specifies the verb 'plan' and the resource 'SEOPass run', and distinguishes from siblings like seopass_status or seopass_register_pack by focusing on planning without persisting results.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies when to use this tool: for planning a run and previewing results without persistence. It mentions 'Chunk 1' which suggests a workflow, but does not explicitly state when not to use it or name alternatives. However, the context is clear enough for an AI to infer usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Discloses idempotency via task_id, duplicate detection (was_duplicate), and retry safety. With no annotations, this provides valuable behavioral context beyond the schema.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Concise three-sentence paragraph that efficiently conveys purpose, behavior, and key parameter details. No unnecessary words, though a structured bullet list might improve scanning.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Covers inputs, behavior, and output (run_id, verdict summary, was_duplicate) adequately. Without output schema or annotations, the description fills the gaps reasonably well.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters5/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Adds significant meaning beyond the input schema, especially for task_id: explains its purpose, recommended generation method, and consequences of omission. Other parameters are also well-contextualized.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool starts a TestPass run against an MCP server, seeds checks, and returns run ID and initial verdict. It distinguishes from sibling tools like testpass_status and testpass_edit_item.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., testpass_status, testpass_report_html) or when not to use it. Missing context for appropriate usage scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided; description conveys a simple read operation (getting a list). It adds enough context without needing extensive behavioral notes.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single concise sentence with no repetition, front-loading the key action and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description and schema together fully specify what the tool does and its parameters. No output schema needed; return list is implied.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a clear parameter description. The tool description adds no additional meaning beyond the schema, meeting baseline expectation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description uses specific verb 'Get' and resource 'BGG Hotness list', clearly distinguishing it from sibling tools like bgg_game_details, bgg_search, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for the hotness list but does not explicitly state when to use it vs alternatives, nor any exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries the burden. It accurately states it's a read operation without side effects, which is transparent. However, it does not disclose error behavior or permissions, which would increase completeness.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that concisely conveys the tool's purpose and key output fields without unnecessary words. It is front-loaded with the verb and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity, the description adequately explains that it returns dimension, metric, status, and host for an index. As there is no output schema, this listing of return fields provides sufficient completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% for both parameters (api_key and index_name). The description does not add additional meaning beyond what the schema already provides, so a baseline of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly specifies the verb 'Get' and the resource 'details (dimension, metric, status, host) for a Pinecone index'. It effectively distinguishes from siblings like list_indexes, which lists all indexes, by focusing on details of a single index.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies that the tool is for retrieving detailed index information but lacks explicit guidance on when to use it versus alternatives (e.g., list_indexes for getting index names). No when-not-to-use or prerequisites are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries full burden. It discloses key behaviors: emits a public push envelope, never builds/merges/assigns/closes/marks done. It lacks details on auth requirements, rate limits, or error states, but provides sufficient context for a pipeline step.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, well-structured sentence that front-loads the action. It uses an emoji for clarity and negation to clarify scope, with no wasted words or redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 16 optional parameters and no output schema, the description provides a high-level understanding of the tool's role in a multi-step process. However, it fails to describe what the tool returns (the 'public worker push envelope') or explain which parameters are essential for typical use, leaving ambiguity about invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so all 16 parameters are documented in the schema. The description does not add additional meaning beyond what the schema provides. It alludes to 'verified IgniteOnly wake packet' but does not elaborate on specific parameter usage, meeting the baseline expectation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's function: running PushOnly on a verified IgniteOnly wake packet and emitting a push envelope for a known worker route. It explicitly differentiates from sibling tools by negating actions it does NOT perform (build, merge, assign, close, mark done), making its purpose distinct.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage context (only on verified IgniteOnly wake packets, only for known worker routes) and excludes alternative actions via negation. However, it does not explicitly mention alternative sibling tools or specify when to choose this over pushonly_wake_pusher or pushonly_policy.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description must cover behavioral traits. It mentions sequential execution and pass/fail/warn results, but omits details like network impact, rate limits, or error handling. Adequate but not thorough.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, front-loaded with purpose, followed by list of checks and outcome description. No unnecessary words, well-organized.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, so description should detail return format. It says 'returns a pass/fail/warn result for each check' but lacks specifics (e.g., structure, error handling). Adequate for simple output but incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, but description adds meaning: explains checks like 'copy quality (em dashes, banned words)' and clarifies the optional 'checks' parameter allows subset selection. This enriches the schema info.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the tool runs a sequential QC checklist against a website URL, listing all checks performed. Distinguishes from siblings like qc_check_api and qc_copy_audit by its comprehensive, sequential nature.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly says when to use (for website QC) and implies comprehensive analysis. No explicit exclusions or alternatives, but sibling tools have different purposes (API check, copy audit) making the context clear.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. Mentions persistence across sessions and updates, but does not disclose overwrite behavior, error handling, or permissions. Adequate but missing key behavioral details for a mutation tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Description is appropriately sized, front-loads purpose, and each sentence is justified. The usage guidelines are well-structured with explicit examples and exclusions. Slightly verbose but still concise given the necessary detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and no annotations, description covers scope, usage boundaries, and distinction from sibling. It implicitly covers update behavior via 'saves or updates'. Leaves some gaps (e.g., what happens if key already exists) but sufficient for typical use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline 3. Description adds no extra meaning beyond schema; it provides example triggers but does not clarify parameter format or constraints. No value added over schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb ('saves or updates'), resource ('standing rule or identity entry'), and scope ('loads at start of every future session'). Distinguishes from sibling save_fact by noting session-scoped vs future session scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly lists when to use (user states/updates identity, preferences, rules) and when not to use (one-time facts, temporary info). Directly names alternative tool save_fact with clear delineation.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so the description carries the burden. It indicates a read-only operation by stating 'searches' and describes the data source. However, it does not explicitly state that it is read-only, mention permissions, or describe behavior on empty results. Adequate but not comprehensive.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three sentences, each efficient: purpose, usage context, sibling differentiation. No redundant or excessive information. Front-loaded with key action.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 2 parameters and no output schema, the description explains data source, typical connections, and when to use. However, it does not describe the return format, pagination, or error handling. Lacks some completeness for a search tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 50% (query has a minimal description, max_results has none). The description adds context for the query parameter by explaining the types of links, but does not address max_results format or constraints. Partially compensates for low coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches graph-style links from memory facts and conversation turns, specifies the types of connections (people, jobs, PRs, etc.), and distinguishes it from search_memory by noting it's for relationship lookups.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicit guidance: 'Use this when a worker needs to find connections...' and 'Prefer search_memory for broad recall and search_typed_links for relationship lookups.' Clearly states when to use and how it differs from the sibling tool search_memory.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the burden of behavioral disclosure. It clearly states prerequisites (transcript must be completed and summarization enabled), but does not specify error handling or response format.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single 17-word sentence that states the purpose first, then the prerequisite. No unnecessary words or repetition.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple retrieval tool with 2 parameters and no output schema, the description covers the essential purpose and prerequisite. It could mention the return format, but the context is largely sufficient.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema already documents the parameters. The description adds context about the transcript needing summarization but does not enhance parameter understanding beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets an AI-generated summary for a completed AssemblyAI transcript, distinguishing it from sibling tools like assemblyai_get_transcript or assemblyai_transcribe. The verb 'Get' and resource 'summary' are specific.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description includes a crucial prerequisite ('must have been submitted with summarization enabled'), guiding when the tool can be used. However, it does not explicitly mention alternatives or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description bears full burden. It discloses that the tool marks signals as read automatically and advises narrating important ones. However, it does not detail potential side effects of multiple calls, permissions, or rate limits, which would enhance transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two succinct sentences. Sentence 1 states the primary action and timing. Sentence 2 lists sources, expected output, and automatic behavior. Every word is necessary, and the structure is front-loaded with the most critical usage guidance.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one optional parameter and no output schema, the description adequately covers purpose, usage, behavior, and parameter meaning. It could be slightly improved by clarifying behavior if called multiple times, but it is largely complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single parameter 'agent_id' has 100% schema coverage, and the description adds meaningful context: it explains the parameter's purpose ('Stable Boardroom agent_id for read attribution') and provides an example value. This exceeds mere schema documentation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: call at session start to catch up on unread signals from specific sources (TestPass, Crews, Memory, every UnClick tool). It uses a specific verb 'call at the start' and defines the resource scope, distinguishing it from sibling tools which are unrelated utilities.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explicitly instructs to 'Call at the start of every session', providing clear timing. It implies not to call again mid-session by mentioning auto-mark-as-read to avoid re-narration. It lacks explicit when-not-to-use scenarios but is clear enough for an agent.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full burden. It states the tool 'returns' a playbook, implying a read operation, but does not disclose any behavioral traits like side effects, permissions, or output format. It is adequate but lacks depth.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence that is front-loaded with action and purpose. No redundant words, every part contributes to clarity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple, zero-parameter tool, the description covers when to call and what it returns. However, it omits details on the output format or how the playbook is structured, which could be useful for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    There are no parameters (0 params), and schema coverage is 100% trivially. Per guidelines, baseline for 0 params is 4. The description adds meaning by explaining the tool's purpose beyond the empty schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool returns the 'canonical CommonSensePass worker sanity-gate playbook' and lists specific claim types (healthy, no_work, etc.). This distinguishes it from sibling tools like heartbeat_protocol or copypass_run.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly says 'Call this when a worker needs to decide if a ... claim makes sense', providing clear context. However, it does not mention alternative tools or when not to use this tool.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the full schema, supportive sibling tools (get_styles, get_status), and no output schema, the description provides sufficient context for an agent to use the tool correctly, though it could mention the api_key requirement.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description adds value by explaining that Soul Styles give 'cinematic looks' and that the return value is a generation_id for polling, which complements the schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it generates a video from a text prompt using Higgsfield AI, mentions Soul Styles for cinematic looks, and indicates it returns a generation_id for polling. This distinguishes it from siblings like higgsfield_generate_image (image) and higgsfield_get_status (polling).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies when to use it (to generate a video) and hints at the workflow (polling with generation_id). However, it does not explicitly name alternatives or state when not to use it, though the sibling tools provide context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. It discloses the two-step flow, env var checking, and localhost page. Does not mention error handling or edge cases, but for a credential connection tool, it is fairly transparent.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three sentences, front-loaded with the main purpose. No wasted words; efficient and clear.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, description explains the two-step process and what to expect (URL from first call). Missing details on second call return value and edge cases (e.g., env var already set), but sufficiently complete for the agent to execute the flow.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% (all 3 parameters documented). Description adds minor context: 'setup_url is shown on the input page.' This slight addition justifies above baseline of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: securely connecting a platform credential without exposing the key. It distinguishes from siblings like keychain_connect by describing the two-step process involving env variables and a localhost page.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Provides explicit guidance on the two-call pattern: 'Call once to get the URL, then call again after the user submits to complete the connection.' Does not explicitly mention when not to use or alternatives, but the guidance is clear enough for typical use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden. It discloses the dry run feature and that live write creates documents, but does not mention potential side effects (e.g., whether it modifies source data), idempotency, or authentication requirements. This is adequate but could be more comprehensive.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences efficiently convey purpose and usage. The first sentence front-loads the core function, and the second adds critical dry run guidance. No redundant information, every sentence earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    While the description covers purpose and dry run, it lacks details about the output format (e.g., what a snapshot preview looks like in dry run, what 'source-linked' means) and how parameters like max_sources affect behavior. For a tool with no output schema, this leaves some ambiguity for the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All 4 parameters are described in the schema (100% coverage). The description adds semantic value by explaining the purpose of the dry_run parameter and when to set it false, which goes beyond the schema's 'preview snapshot output' phrasing. No extra semantics for other parameters, but the key parameter is enriched.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool builds source-linked Memory Library taxonomy snapshots from active facts and sessions, using specific verbs and resources. It also distinguishes itself from the large set of unrelated sibling tools by describing its unique function.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explicitly explains when to use dry run (default) and when to set dry_run=false, providing a clear workflow: inspect planned snapshots first, then write live if safe. This guides the agent on proper usage without needing to reference alternatives.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so the description carries the full burden. It discloses that it posts a short reply in the original thread via Boardroom post path and explicitly states what it does not do. This is adequate transparency for a simple mutation tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences plus usage guidance, all front-loaded with no extraneous information. Every sentence adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, but the description provides enough context that the ACK card includes the provided fields and is posted in the thread. It could mention response format or error cases, but for a simple tool it is largely complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with good parameter descriptions. The overall description adds context by explaining the purpose of the parameters in the ACK card (ownership, next action, ETA, blockers), which adds meaning beyond individual schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description specifies the verb 'Replies', the resource 'Boardroom handoff', and the outcome 'structured ACK card'. It clearly distinguishes from sibling communication tools by focusing on Boardroom handoff specifically.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description includes explicit when-to-use conditions (directly addressed, tagged handoff, asks to confirm receipt) and what it does not do (no todo claiming or code change). It does not mention when not to use it, but the positive guidance is strong.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description carries the full burden. It explains that default output is compact for strict MCP clients and warns that full_content may be rejected. It also implies a read-only load operation. However, it does not explicitly state if any state is modified or if there are side effects, but the reading is clear.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is lengthy but each sentence is purposeful, providing critical usage guidance. It is front-loaded with the core purpose. While it could be slightly more concise, the level of detail is justified given the complexity of when to use the tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the lack of an output schema, the description gives high-level components (identity, preferences, facts, session history) but does not detail the structure of the returned data. This leaves some ambiguity for the agent on how to parse the output, though the usage context is clear.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description adds meaning by explaining that lite=true produces compact output and full_content should be used sparingly due to client restrictions. It also ties the parameters to the use case of narrow vs. full payload, referencing search_memory for context.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it loads user identity, preferences, facts, and session history from persistent storage. It distinguishes itself from the sibling tool search_memory by specifying that search_memory is for narrow questions, while load_memory is for full context at session start.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides explicit when-to-use guidance: 'Use IMMEDIATELY at the start of every session -- before responding to the user's first message, before calling any other tool.' It also lists keywords that signal stored context, says when not to skip, and when not to trigger (pure factual lookups). Alternatives like search_memory are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description fully discloses key behaviors: LLM turn flow via MCP sampling, SAMPLING_NOT_SUPPORTED fallback, and was_duplicate on idempotent retry. This is comprehensive and beyond minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is front-loaded with purpose and return type, then provides behavioral details. It is informative but slightly long; could be tightened without losing substance.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 4 parameters (2 required), no output schema, and no annotations, the description is remarkably complete: it explains the action, return type, edge cases (sampling not supported, duplicate), and idempotency key usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description adds context about was_duplicate and retry safety (task_id) but does not elaborate on other parameters beyond schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's verb ('start a Crews Council run'), resource ('run row on UnClick API'), and return type ('ConversationalCard'). It distinguishes from siblings by being unique in the large list of tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly says 'Call this tool when the user wants to start a Crews Council run', providing clear context. It does not mention when not to use or alternatives, but the sibling list is vast and unrelated.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, but description discloses that agent_id must be stable for attribution and emphasizes the noticeboard nature. Lacks details on persistence or failure behavior, but sufficient for a basic post action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Well-structured with front-loaded purpose and clear guidelines. Concise for the amount of guidance given, though the list of canonical tags could be shortened or moved to schema examples.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Lacks explicit description of return value (e.g., message ID or success indicator) and does not mention idempotency or duplicate handling. For a complex tool with 5 parameters, these omissions are notable.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters5/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Adds significant value beyond schema: explains agent_id must match set_my_emoji, provides canonical tag list with usage notes, clarifies recipient options (emojis vs agent_ids) and their trade-offs, and explains thread_id usage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Title and description clearly state verb ('Posts') and resource ('the Boardroom'), and distinguish it as a coordination room for material work updates, which sets it apart from sibling communication tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly states when to use (material events like PR opened, blocker hit) and when not to use (stream-of-consciousness, trivial steps), and provides canonical tags for consistency.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Discloses validation, persistence, and return value. In absence of annotations, description is fairly transparent, though could mention overwrite behavior or error conditions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three sentences, front-loaded with action, each sentence adds essential information. No unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a single-parameter tool with no output schema, the description adequately explains input, validation, persistence, and return, making it complete for the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema already describes the parameter (pack_yaml) with 100% coverage. Description adds context about validation of required keys, which adds value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the action (register), resource (UXPass pack), input format (YAML string), validation (basic shape with required keys), and outcome (persists, returns pack_id). Distinguishes from siblings like uxpass_run and uxpass_status.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Implicitly indicates usage after which uxpass_run can be called, but lacks explicit when-to-use or when-not-to-use guidance compared to alternatives.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Given no annotations, the description carries the full burden. It discloses synchronous execution, deterministic nature, idempotency via 'was_duplicate' field, and explains the 'hats' parameter is ignored. This provides good behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single paragraph of 6 sentences, front-loading the main purpose. Every sentence adds useful information without redundancy, making it concise and well-structured.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Without an output schema, the description explains all key return fields (run id, status, UX Score, summary, was_duplicate). It covers parameter options, idempotency, and the scope of checks, leaving no significant gaps for a run tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All 4 parameters have descriptions in the schema (100% coverage). The description adds value by explaining that 'pack_name' resolves the pack's URL, 'hats' is for future use, and 'task_id' provides idempotency with retry behavior. This goes beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it runs a UI/UX quality check synchronously against a URL, listing specific check categories (HTTP, HTML, accessibility, etc.) and return fields (run id, status, UX Score, summary). It distinguishes between the 'url' and 'pack_name' parameters, avoiding ambiguity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explains when to use 'url' vs 'pack_name' (one-off vs registered pack) and notes that 'hats' is for forward compatibility but ignored. It does not explicitly compare to sibling tools like 'uxpass_status' or 'uxpass_register_pack', but the usage context is clear.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description carries full burden. Clearly discloses hard-deletion (destructive), cascading deletion of comments, and audit log requirement for agent_id.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences with no wasted words. Key information (action, side effects, guidance, param hint) is front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Covers effect, side effects, alternatives, and param context. Lacks return value description, but no output schema exists. Overall adequate for simple tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 0% description coverage, so description must compensate. It explains agent_id's role in audit log, but does not elaborate on todo_id beyond its obvious purpose. Partial compensation.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states it performs a hard delete of a todo and its comments. Distinguishes from sibling drop_todo by explicitly naming it and contrasting behavior.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly advises to use drop_todo instead for history preservation, and states to use this tool sparingly. Also declares agent_id requirement for audit logging.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description carries the full burden. It discloses that the fact is not deleted but marked invalid, preserving history. This adds useful behavioral context beyond the tool's basic purpose.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with four sentences; each sentence adds value. It is front-loaded with the purpose and immediately provides usage guidance and behavioral insight.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity and full schema coverage, the description adequately explains behavior and input sources. It could mention the return value or success indication, but overall it is sufficient.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, but the description adds context: fact_id must come from prior tools, reason is optional but recommended, session_id for audit log. This enhances understanding beyond schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool marks a stored fact as no longer valid, using a specific verb and resource. It distinguishes itself from save_fact by explicitly indicating when not to use it.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides explicit guidance on when to use (user corrects a fact, says something has changed, asks to forget) and when not to use (new information, use save_fact instead). It also specifies the prerequisite of having a fact_id from save_fact or search_memory.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description accurately reflects the tool's behavior without any hidden effects. No annotations are provided, but the tool is stateless and safe, so transparency is complete.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence of five words. It is perfectly concise with no wasted words. Front-loading is irrelevant due to extreme brevity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is sufficient for the tool's simplicity. It could mention the return type (e.g., UUID string), but the name and schema imply it. No output schema, so the description could be slightly more helpful.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    There are no parameters, so the schema coverage is 100%. The description adds no param-specific information, but none is needed. Baseline 4 for zero parameters is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Generate a random UUID.' clearly states the verb (generate) and resource (random UUID). It is unambiguous and leaves no room for confusion.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Although no alternatives exist, the description does not provide any context on when to use this tool. However, given the simplicity, the lack of guidance is not a major issue.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations are provided, so the description carries full responsibility. It discloses that the tool reads continuity and may fail, with a specific failure response. It does not detail side effects (though as a read, few are expected) or permissions. The description adequately signals the tool's role and failure mode, but could be more explicit about what 'continuity' entails.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences: first defines purpose, second provides usage guidelines and failure handling. No extraneous words. Every sentence earns its place. The structure is front-loaded with the primary action.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description does not specify the return format. However, it explains that the tool reads 'continuity' to help interpret a turn, which implies the output will contain context. The description is complete enough for the agent to understand the tool's place in the workflow and its behavior on failure. A brief mention of return structure would improve completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with 5 parameters all described. The description adds value beyond the schema by tying the 'q' parameter to the saved turn text and implying the 'limit' and 'compact' parameters are typical for reading. It does not elaborate on 'max_summaries' or 'include_raw', but the schema descriptions are sufficient. The description's workflow context enhances parameter understanding.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Reads current UnClick Orchestrator continuity so a seat can interpret a freshly saved turn before acting.' It specifies the action (read), the resource (orchestrator continuity), and the purpose (interpret a saved turn). It distinguishes itself from siblings by explicitly referencing the required workflow and the sibling tool save_conversation_turn.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides explicit when-to-use instructions: 'Use immediately after save_conversation_turn in the required Log -> Read -> Decide -> Reply -> Log reply gate.' It also gives clear fallback behavior on failure: 'If this read fails, say CONTEXT_UNREAD or UNTETHERED instead of guessing...' This guides the agent on proper sequencing and error handling.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, but description discloses the operation's purpose and warns against storing secrets. However, it lacks details on overwrite behavior, content size limits, or error responses, which would enhance transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Four sentences, all essential. Front-loaded with purpose, then usage guidelines, then parameters. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is adequate for a simple write tool with no output schema. It explains the context (Orchestrator continuity) and constraints. Missing details on success/error feedback, but given the tool's simplicity, it's nearly complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers all parameters with descriptions. The description adds context about using a stable session_id and ensuring content has secrets removed, which goes beyond schema. High schema coverage means baseline 3, so 4 reflects added value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool saves a turn from various roles into UnClick conversation history, with a specific verb and resource. It distinguishes itself from siblings by tying to Orchestrator continuity and being the primary receipt path.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly specifies when to use (after accepted human turn and assistant reply when client can call tools), and provides fallback instructions if unavailable. Also advises using stable session_id and avoiding secrets.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description fully bears the burden. It discloses persistence across sessions and proactive saving triggers. It does not describe side effects like overwriting or return values, but the core behavioral traits are well covered.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is lengthy but every sentence serves a purpose. It front-loads the core purpose and then provides rich usage guidance. Could be slightly tighter, but the depth justifies the length.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's importance for long-term memory and 7 parameters, the description covers proactive triggers, exclusions, formatting, and context. No output schema exists, but the purpose is straightforward save.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 86%, already good. Description adds value by specifying the 'troubleshooting' category format and explaining when to use 'preserve_as_blob'. It does not detail all parameters but complements the schema effectively.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it 'Saves a new persistent fact about the user that will be available in all future sessions across every AI tool.' This is a specific verb+resource combination and distinguishes it from all sibling tools (none of which are memory-related).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Provides explicit when-to-use examples (preferences, decisions, corrections, etc.), when-not-to-use (transient values, already confirmed facts), and alternatives not needed as it's the sole fact-saver. Also gives formatting instructions for troubleshooting.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Discloses response structure (two lanes: messages and mentions), the need for a stable agent_id, and that user posts may have specific emoji. Without annotations, description carries full burden; it is thorough but could explicitly state read-only nature and any rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Efficiently structured with front-loaded purpose, clear paragraphs, and bullet points. Every sentence adds value, no fluff.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and simple parameters, description covers purpose, usage, parameters, response format, and workflow loop. Sufficient for an agent to use correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Adds meaning beyond schema: explains agent_id must match other calls, since filters after known timestamps, limit caps at 20 default. Schema has 67% coverage; description fills gaps and provides usage context.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it reads messages from the Boardroom, a specific build coordination room, and distinguishes itself from sibling tools like load_memory and set_my_status by specifying its role in the start-of-session workflow.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly says when to use: right after load_memory at session start, when user asks for updates. Also says when not to use: do not poll repeatedly. References alternative tools like set_my_status and post_message.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations provided, the description fully discloses hybrid search method, content cap, full_content behavior, and include_card option. It sets clear expectations without contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Front-loaded with purpose and key details. Slightly long due to extensive usage guidance, but well-organized. Could trim redundant phrases.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Comprehensive for a search tool with 5 parameters and no output schema. Covers purpose, usage rules, parameter effects, and behavior. Missing some specifics about return format but adequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is high (80%), and the description adds context for full_content (use sparingly), as_of (point-in-time), and include_card (Phase 1 Wizard opt-in). However, query parameter could have more usage examples.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it searches stored facts and session history using hybrid retrieval. It distinguishes itself from sibling tools like load_memory by specifying search behavior.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Provides explicit triggering conditions (remember, recall, etc.) and non-triggering cases (one-shot math, translations). Also advises against triggering if load_memory was just called.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    With no annotations, the description fully discloses behavior: it registers agent, requires stable agent_id, picks emoji, and sets display name. It warns about reusing agent_id and not calling repeatedly. No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Well-structured: starts with purpose, then usage guidelines, then parameter details. No wasted sentences; all information is actionable.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Covers purpose, when, why, and parameters. Lacks information about return values or error handling, but for a registration tool with no output schema, this is adequate. Slight gap: no mention of side effects like overwriting.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters5/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Adds meaning beyond the schema: agent_id must be stable and reused, emoji should fit the model, display_name in plain English. Schema already describes all parameters, but description provides critical usage context.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool registers an AI agent in the user's Boardroom, using an emoji and display name. It specifies exactly what it does and differentiates from siblings by mentioning the unique registration action.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly states when to call ('ONCE on first connect'), provides trigger phrases, and warns against calling every session. Also includes negative guidance ('Do NOT call this on every session').

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    No annotations provided, so description fully carries the burden. It discloses required agent_id, the optional next_checkin_at behavior with detailed explanation of display and MIA status, and that status persists until changed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two efficient paragraphs: first covers core purpose and usage, second details the optional parameter. No fluff, every sentence adds necessary information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, description doesn't need to explain return values. It covers purpose, usage, parameters, and behavioral details comprehensively for a mutation tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters5/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, baseline 3. Description adds significant value: explains agent_id as stable identifier, status max 200 chars, and next_checkin_at thoroughly—ISO/duration formats, UI behavior, clearing with empty string.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool updates the human's Now Playing status, using specific verb 'Update' and resource 'status'. It distinguishes well from siblings as no other sibling tool appears to set the human's status.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly states when to call: 'Call when you start a task, change focus, or idle out.' Also explains persistence and the dead-man's-switch use case, providing clear context without needing alternative tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
