Server Quality Checklist

58%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v0.2.0

  • Disambiguation4/5

    Most tools have clear distinct purposes, but 'ask_question' and 'ask_simple' are very similar in functionality and arguments, potentially causing confusion for an agent. Other tools like CRUD operations are well-separated.

    Naming Consistency5/5

    All tool names follow a consistent verb_noun pattern with lowercase and underscores (e.g., create_notebook, delete_source). No mixing of conventions or irregular names.

    Tool Count4/5

    With 33 tools, the server is on the higher side but still reasonable given the multiple resources (notebooks, notes, sources, chat sessions, models, settings) and additional utility tools. It's slightly over the typical well-scoped range but not excessive.

    Completeness4/5

    The tool surface covers CRUD operations for all major resources and includes question-asking and search features. Minor gaps like import/export or bulk operations are missing, but core workflows are well-supported.

  • Average 3.2/5 across 33 of 33 tools scored. Lowest: 2.4/5.

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

How to sync the server with GitHub?

Servers are automatically synced at least once per day, but you can also sync manually at any time to instantly update the server profile.

To manually sync the server, click the "Sync Server" button in the MCP server admin interface.

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

  • 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 mentions 'Returns: Built context data' but does not disclose side effects, authentication needs, or what 'context' entails.

    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 and uses an Args/Returns structure, which is clean. However, it is under-specified rather than concise, lacking substance in the Returns section.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence 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 high number of sibling tools and the presence of an output schema, the description should clarify how build_context relates to other chat operations and what 'built context data' contains. It currently falls short.

    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 merely repeats the parameter names ('notebook_id', 'context_config') without adding any meaning about their format, constraints, or purpose 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 'Build context for a chat conversation' which is a clear verb+resource combination. However, it does not differentiate from sibling tools like 'get_chat_session' or 'ask_question', so it's not maximally 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. 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?

    No annotations are provided. The description only states the function is 'simplified' but reveals no behavioral traits such as side effects, authentication needs, rate limits, or constraints. It offers little 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.

    Conciseness3/5

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

    The description is short but not optimally structured. It includes an Args list but no front-loaded summary of the most critical information. It is not verbose, but could be more concise while retaining 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 the complexity (5 parameters, no annotations, output schema exists but not described), the description is incomplete. It lacks explanations of the 'simplified' aspect, error handling, return value details beyond 'Simple answer', and any contextual usage hints.

    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 merely lists parameter names (e.g., 'strategy_model') without any explanation of their meaning, acceptable values, or how they affect the tool's behavior. The agent must infer from 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 'Ask a question about your content with simplified interface,' which identifies the verb (ask) and resource (questions on content). It hints at a simplified version compared to siblings like ask_question, but does not explicitly name or differentiate from it.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select 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., ask_question). The phrase 'simplified interface' implicitly suggests use when a simpler endpoint is desired, but there is no explicit 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 should disclose side effects (e.g., permanent deletion, impact on associated data) but only states 'Delete a chat session,' lacking 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, but conciseness comes at the cost of essential details; the structure is logical but 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?

    For a simple delete tool with one parameter, the description lacks completeness: no return value details (beyond 'Success message'), no error conditions, no idempotency info.

    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 merely restates 'session_id: Session ID,' adding no semantic value beyond the input 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 chat session') with a specific verb and resource, distinguishing it from sibling tools like delete_model or delete_note.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select 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., update_chat_session), 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?

    No annotations provided and the description does not disclose any behavioral traits such as irreversibility, dependencies, or side effects of deletion. The minimal description fails to inform the agent of important properties.

    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 and to the point, with no unnecessary information. However, it sacrifices completeness for 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?

    For a simple deletion tool with one parameter, the description is adequate but missing details like error handling or whether the operation is destructive. It provides basic completeness but 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 only repeats 'model_id: Model ID' without adding format, validation, or examples. This 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.

    Purpose4/5

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

    The description clearly states 'Delete a model configuration' using a specific verb and resource. While it doesn't explicitly differentiate from sibling delete tools, the purpose 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?

    No guidance on when to use this tool or when not to. No prerequisites or alternatives mentioned, leaving the agent without 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 provided, so description must disclose behavior. It only says 'Delete a note' and 'Returns: Success message', without explaining permanence, cascading effects, permissions, 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 very short and front-loaded but lacks critical details. It is concise but under-specified for a delete operation.

    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 is a delete operation with no annotations and a simple schema, the description is inadequate. It fails to address behavioral traits, usage context, or parameter details, making 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?

    Parameter 'note_id' is described as 'Note ID', which adds minimal value beyond the schema title. No format, source, or constraints are explained.

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

    Purpose5/5

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

    The description clearly states 'Delete a note' with a specific verb and resource. It distinguishes from siblings like create_note, update_note, get_note.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select 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 delete_notebook or update_note. Lacks prerequisites, side effects, 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?

    With no annotations, the description must disclose behavioral traits. It only states 'Update a note' and 'Returns updated note details', missing information on side effects, permissions, 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.

    Conciseness4/5

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

    The description is well-structured with Args and Returns sections, and it is concise. No unnecessary information, but could be slightly more compact.

    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 presence of an output schema, return values are covered. However, the description does not address error cases (e.g., missing note_id) or the nature of partial updates. Adequate but not comprehensive.

    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%, yet the description merely restates the parameters (e.g., 'Optional new title') without adding meaningful constraints or usage context. It 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.

    Purpose4/5

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

    The description clearly states 'Update a note', which is a specific verb and resource. However, it does not differentiate from other update tools like update_notebook or update_source, but the purpose is still 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 like create_note or delete_note. The description lacks context for proper 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 bears the full burden of disclosing behavioral traits. It merely states 'Update a source' without detailing side effects, idempotency, permission requirements, or whether updates are partial or full replacements. This is 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 short (three lines), but it is not efficiently informative. It repeats schema information without adding critical behavioral or usage context. A more structured approach with front-loaded key details 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 complexity of an update operation (partial vs full, optional fields), the description is inadequate. It does not clarify the update semantics, return behavior, or error conditions. With no annotations and an output schema present, the description should provide more context 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?

    The description adds some semantic value over the schema by labeling title as 'Optional new title' and topics as 'Optional list of topics', but it does not explain whether topics replaces or appends to existing topics. Since schema description coverage is 0%, the description partially compensates but remains incomplete.

    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 'Update a source' clearly states the verb and resource, distinguishing it from sibling tools like create_source, delete_source, and list_sources. However, it could be more specific about what aspects of the source can be updated (e.g., 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 create_source or other update tools. There is no mention 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.

  • Behavior3/5

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

    With no annotations, the description must carry the full burden. It mentions the multi-stage process (strategy, answer, final) and return type, but does not disclose side effects, authentication needs, 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?

    Concise with clear Args/Returns structure. The purpose is front-loaded. Every sentence is relevant, though formatting could be more formal.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence 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 5 parameters and a multi-step process, the description is incomplete. It lacks elaboration on the model parameters and does not fully explain the returned 'sources and reasoning'.

    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 is crucial. It lists parameter names but only explains 'question' briefly. The three model parameters are not differentiated, and 'notebook_id' gets minimal 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 clearly states the verb 'ask' and resource 'question about your content'. It hints at 'detailed control' but does not explicitly differentiate from the sibling tool 'ask_simple'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select 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 'ask_simple' or 'search'. Lacks context about prerequisites or exclusionary 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?

    No annotations are present, so the description must fully disclose behavioral traits. It only states it creates a session and lists parameters. It does not mention whether the operation is destructive, if it requires specific permissions, or if there are limits on session creation.

    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 short and to the point, with a clear one-line purpose followed by structured args and returns. It is front-loaded and efficient, though 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.

    Completeness3/5

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

    The tool is simple with two required parameters and an output schema (not shown). The description mentions a return value but is vague. It provides enough for a basic understanding but lacks completeness in usage context and behavioral 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?

    Schema coverage is 0%, so the description must add meaning. The Args section provides brief explanations: 'Notebook ID for the session' and 'Session title'. This adds some context beyond the schema's type and title, but lacks details on constraints or 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 'Create a new chat session.' which is a specific verb+resource combination. It distinguishes from sibling tools like create_note or create_model. However, it could elaborate on what a chat session is in this 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 create versus update or delete a chat session. Sibling tools include update_chat_session and delete_chat_session, but the description does not clarify scenarios where creating is appropriate.

    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 behavioral disclosure. It fails to mention side effects (e.g., overwriting existing models), required permissions, error handling, or whether the operation is asynchronous. Only states 'Create a new AI model configuration.' without any safety or 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 efficiently structured using a docstring format with Args and Returns sections. Every sentence provides necessary information with no wasted 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?

    Although the tool has an output schema, the description only vaguely mentions 'Created model details,' leaving out specifics like what fields are returned. Missing behavioral details (error states, uniqueness constraints) and lack of usage guidance make it incomplete for a 3-parameter creation tool with no annotations.

    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 0%, so the description provides the only documentation for the three parameters. It adds concrete examples (e.g., 'gpt-4', 'openai', 'language') that clarify expected values beyond the schema's empty descriptions. However, it does not specify constraints like allowed providers or types beyond 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 creates a new AI model configuration, using a specific verb ('Create') and resource ('AI model configuration'). It is distinct from sibling tools like delete_model or list_models, but does not differentiate from other 'create_*' tools beyond the 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?

    No usage guidance is provided. The description does not specify when to use this tool versus alternatives (e.g., update_model, which does not exist but could be inferred), nor does it mention prerequisites, when-not-to-use, or potential duplicates.

    Agents often have multiple tools that could apply. Explicit usage guidance like "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 merely states the action without mentioning permissions, idempotency, side effects, or return value details beyond a vague 'Created notebook 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 short and includes Args/Returns sections, but the Returns section is vague. It is efficient but lacks specificity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence 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 an output schema (implied), the description fails to provide context about notebook creation, such as expected behavior, relationship to other entities, or error conditions. For a tool among many siblings, it is insufficient.

    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 repeats parameter names ('name', 'description') without adding constraints, defaults, or format details. 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 clearly states the action ('Create a new notebook') and the resource ('notebook'). It distinguishes from sibling tools like delete_notebook, update_notebook, and list_notebooks.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select 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 create_note or create_source. Prerequisites or contextual usage 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 provided, the description fails to disclose behavioral traits like side effects, permissions, or whether embeddings are generated automatically. It only mentions the embed parameter but not the implications.

    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 clear 'Args:' section and a 'Returns:' line. It avoids unnecessary words while covering the main points.

    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 output schema exists and 5 parameters, the description covers the basics but lacks completeness on usage contexts, prerequisites, or validation. 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?

    Schema coverage is 0%, so the description must add value. It gives brief explanations for each parameter (e.g., 'URL for link type sources'), which helps but lacks further detail on constraints or 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 'Create a new source (link, upload, or text)' which specifies the action and the types of sources. It distinguishes from sibling tools like update_source or delete_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?

    The description does not provide any guidance on when to use this tool versus alternatives. There is no mention of when not to use it or references to 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 provided. The description does not disclose behavioral traits such as permanence, cascading effects, required permissions, or whether deletion is reversible.

    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 and to the point, with no wasted words. 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 no annotations and a single parameter, the description provides minimal context. It does not explain the output beyond 'Success message' or describe any constraints or side effects.

    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 restates the parameter name 'notebook_id: Notebook ID' which adds no meaning beyond the schema property 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 'Delete a notebook' which is a specific verb+resource. It easily distinguishes from sibling tools like create, update, get, list notebooks.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps 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.

    Completeness3/5

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

    Adequate for a simple tool with 3 parameters and an output schema (not shown). However, it lacks contextual completeness: it does not mention that a chat session must exist, or how the tool behaves if the session is invalid. The return value is described generically as 'Chat response with AI message' but no details about the response 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?

    Schema description coverage is 0%. The description adds one-line explanations for parameters (e.g., 'Session ID', 'Optional context data'), but these add only marginal meaning beyond the parameter names. Context parameter gets a slightly more detailed description, but overall the parameter semantics are minimal.

    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 'Send a message in a chat session'. However, it does not explicitly differentiate from sibling tools like ask_question or ask_simple, which might also involve sending messages in a session.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select 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 ask_question or ask_simple. The description only states what the tool does without providing decision criteria.

    Conciseness4/5

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

    The description is concise and front-loaded, using a clear list for arguments. Every sentence serves a purpose, though it could be 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?

    For a simple update tool with two parameters and an output schema, the description covers basic context but lacks usage guidelines and behavioral details, leaving some 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 0%, so the description must add meaning. It explains that 'title' is optional and a new value, but does not elaborate on constraints or the 'session_id' format. This is adequate but minimal.

    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 'Update' and resource 'chat session', making the purpose obvious. However, it does not differentiate from siblings like create_chat_session or delete_chat_session, which could be improved.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select 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., create_chat_session or execute_chat). The description lacks context for appropriate usage.

  • Behavior2/5

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

    No annotations provided. Description implies modification but lacks details on side effects, permissions, or whether updates are additive or destructive. The return type is mentioned but not elaborated.

    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 extremely short and front-loaded. However, it sacrifices necessary detail for brevity, 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?

    Despite simple structure and one parameter, the description omits critical details about the 'settings' object structure and expected behavior. Output schema exists but is not shown; description only says 'Updated settings' without specifics.

    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 restates 'Settings dictionary to update' with no explanation of valid keys, format, or constraints. Fails to compensate for the schema's lack of descriptive 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?

    Description clearly states 'Update application settings.' The verb 'update' and resource 'application settings' are specific. It distinguishes from sibling tools like get_settings (read) and other update tools for different resources.

    Completeness3/5

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

    Given the tool's complexity (4 params, no annotations), the description covers basic inputs and outputs but misses context like prerequisites (e.g., notebook existence), error handling, or idempotency. The output schema exists but is not leveraged in 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?

    Schema description coverage is 0%, requiring the description to explain parameters. However, it only restates parameter names (e.g., 'Notebook ID to add note to') without adding format, constraints, or validation details. The topics parameter is noted as optional but still lacks depth.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid 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 creates a new note, using specific verb 'Create' and resource 'note'. It lists relevant parameters (notebook_id, title, content, topics) that distinguish it from sibling tools like create_notebook or create_model.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps 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?

    Despite the tool's simplicity, the description lacks completeness. It omits details about return value format (only 'Success message'), error conditions, and required permissions. The absence of annotations and output schema leaves gaps for the agent to understand the 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 restates the parameter name and type ('source_id: Source ID') without adding meaningful context beyond the input schema. It does not explain what a source ID is, how to obtain it, or any constraints. The schema description coverage is 0%, and 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 action 'Delete' and the resource 'source', leaving no ambiguity about the tool's purpose. It is specific and directly corresponds to the tool name, distinguishing it from sibling tools that operate on other resources.

    Completeness3/5

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

    Given the presence of an output schema, the description does not need to detail return values. However, it lacks context about what 'application settings' entails, which may be necessary for differentiation from sibling tools like get_default_models. The description is minimally 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?

    The tool has no parameters, so the description does not need to add parameter semantics. With 100% schema coverage (trivially empty), the baseline is 4, and the description adds no further 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 'Get application settings,' which indicates the verb and resource. It is simple and unambiguous, but it does not elaborate on what settings are included, which could help distinguish it from related tools like get_default_models.

    Completeness3/5

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

    Given the 4 parameters and lack of annotations, the description is adequate but not rich. It explains each parameter simply but omits details like search behavior, ranking, or pagination. The output schema likely covers return structure, so missing return explanation is 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?

    Schema description coverage is 0%, so the description must compensate. It provides brief but meaningful explanations for each parameter (e.g., enum values for 'type', default for 'limit'), adding value beyond the bare 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 content using vector or text search. It specifies the main action and resource, but does not explicitly differentiate from sibling tools like 'ask_question' or 'search_capabilities', which might be related.

  • Behavior2/5

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

    No annotations are provided, so the description is the sole source of behavioral information. It only says 'Returns Model details' without disclosing error behavior (e.g., if ID is invalid), permission requirements, or whether the operation is safe. The description adds minimal behavioral context beyond the obvious 'get' intent.

    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?

    Completeness3/5

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

    Given the tool has a single parameter, is read-only, and an output schema exists to define return values, the description covers the basics. However, it lacks detail on error handling, permissions, or the structure of the returned model details, which would be helpful 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 description coverage is 0%, so the description's docstring adds value by providing an example format ('model:abc123') for model_id. However, it does not explain constraints like allowed characters or length. It partially compensates 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 'Get a specific model by ID.' The verb 'Get' and resource 'model' are specific. It distinguishes from sibling tools like list_models (which returns all models) and other get tools by its 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 versus alternatives like list_models or search. It does not mention prerequisites (e.g., having a valid ID) or when not to use it. The description lacks any contextual usage advice.

    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 presence of an output schema, the description provides adequate high-level information. However, it lacks usage context and behavioral details that would help an agent decide when to call this 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?

    The input schema has 0% description coverage, so the description adds value by providing an example format ('note:abc123') for the single parameter 'note_id'. This helps the agent understand the expected value syntax beyond the schema's type declaration.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid 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 'specific note by ID', making the tool's purpose immediately obvious. It distinguishes itself from siblings like 'list_notes' by focusing on retrieval of a single note by ID.

    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 search or list_notebooks. Among many sibling get tools, explicit context on when to choose this one 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?

    With no annotations provided, the description bears full responsibility for behavioral disclosure. It states 'Get all' but includes a limit parameter, which is contradictory. It does not mention read-only nature, pagination, or ordering behavior, leaving important behavioral traits unclear.

    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 concise and front-loaded with the main purpose. It uses structured sections (Args, Returns) which aid readability. However, the sections add redundancy since the schema already defines the parameter and output.

    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 with one parameter and an output schema, so the description is mostly adequate. However, it lacks context on what 'configured' means, potential prerequisites, or how it relates to user-specific models. The output schema likely covers return values, but missing broader usage context.

    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 description adds value by specifying 'limit: Maximum number of results (1-100)', which clarifies the range beyond the schema's default. Schema coverage is 0%, so this manual description compensates well for the only 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 explicitly states 'Get all configured AI models' with a clear verb and resource. It distinguishes itself from siblings like 'get_model' (singular) and 'get_default_models' (specific subset).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select 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 'list_models' versus alternatives like 'get_default_models' or 'get_model'. The description does not mention contexts or exclusions, leaving the agent to 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.

  • Behavior3/5

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

    No annotations provided, so description carries burden. 'Get' implies read-only, but does not explicitly state safety or lack of side effects. Mentions return includes message history, which adds context, but misses authentication or rate limit info.

    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: one-line purpose, then args and return sections. Front-loaded with main action. No unnecessary words, but could be slightly more structured with headers.

    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, parameter example, and return value with 'message history'. Output schema exists, so return details are covered. Lacks mention that session_id is required (though schema indicates required), and no prerequisites or error handling hints.

    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 0%, so description compensates well: explains parameter 'session_id' and provides an example format 'session:abc123'. Adds meaning beyond the bare schema definition.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious 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 specific chat session by ID.' The verb 'get' and resource 'chat session' are explicit. Distinguishes from sibling tools like list_chat_sessions (list all) and create_chat_session (create).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select 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 fetching a single session by ID, while list_chat_sessions is for retrieving all sessions. 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 provided. The description only states the action (get) and return value, without disclosing behavioral traits like idempotency, caching, or permission requirements. Minimal information for a tool with zero 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?

    Extremely concise: two lines, no fluff. Every word is necessary and front-loaded with the 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?

    Given the tool has an output schema and no parameters, the description is minimally adequate. However, it lacks context about what 'default' means or how this configuration is used, which could help an agent decide when to call it.

    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 in the schema, so schema coverage is 100% trivially. The description adds no parameter info, but with zero parameters, baseline 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 clearly states the tool retrieves default model configurations. It uses specific verb 'Get' and resource 'default model configurations', distinguishing it from siblings like get_model or 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?

    No explicit guidance on when to use this tool vs alternatives. While it's implied for retrieving defaults, the description does not mention when-not or provide context for selection among similar read-only 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, the description bears full responsibility for transparency. It mentions the return type (dictionary with notebooks list and metadata) but omits details like whether it is read-only, pagination behavior, or performance implications. It is adequate 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 concise and well-structured using a standard Args/Returns format. Every sentence adds value, with no redundancy or fluff. It is 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.

    Completeness4/5

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

    Given the presence of an output schema, the description need not detail the return structure fully. It covers the arguments well and explains the return type. Minor gaps (e.g., no explicit mention of pagination beyond limit) prevent a perfect score, but it is nearly complete.

    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 description coverage is 0%, so the description must fully explain parameters. It does so excellently, providing clear semantics for 'archived' (filtering options), 'order_by' (format with example), and 'limit' (range). This adds significant value beyond the schema's type-only definitions.

    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 notebooks with optional filtering and ordering (specific verb+resource). However, it does not explicitly distinguish this tool from sibling list tools like list_notes or list_sources, relying on the resource name to 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 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., search, get_notebook). It does not mention when-not to use it or any prerequisites. The usage context is implied only by the tool's 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?

    With no annotations, the description carries the full burden of behavioral disclosure. It only states the input parameters and return type, but lacks information about side effects, required permissions, error handling, or atomicity. For a mutation 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.

    Conciseness5/5

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

    The description is extremely concise, listing only essential information in a structured format (Args and Returns). Every sentence is necessary, and it avoids 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?

    Given the tool's complexity (4 parameters, output schema exists) and no annotations, the description is minimally adequate. It covers the basics but omits context like error scenarios, idempotency, or whether partial updates are supported. An average score is fair.

    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 description adds meaning beyond the schema by labeling each parameter (e.g., 'Notebook ID', 'Optional new name'). Although the schema has 0% description coverage, the description compensates reasonably well, but still lacks detailed syntax 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 'Update a notebook,' using a specific verb and resource. This distinguishes it from siblings like create_notebook, delete_notebook, and get_notebook, 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 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. While the name and context imply it's for modifying existing notebooks, there is no mention of prerequisites or when not to use it. A minimal viable score is appropriate.

    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 describes a read operation ('Get'), which implies no destructive side effects, but does not explicitly state permissions, error conditions, or safety guarantees. Minimal but 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 brief (5 lines), front-loaded with the key summary, and contains no unnecessary words. The Args/Returns sections are clearly structured and immediately useful.

    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 is simple (1 param, read-only), an output schema exists (so return values are documented), and sibling tools are present, the description covers the essential retrieval purpose. It could mention error behavior (e.g., not found), but is otherwise 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 schema provides no description for 'source_id' (0% coverage), but the description adds a format example ('e.g., source:abc123'), which clarifies the expected input beyond the schema's bare type 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 its verb ('Get') and resource ('a specific source by ID'), distinguishing it from siblings like 'list_sources' (which retrieves all) and 'create_source' (which creates new 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 does not explicitly state when to use this tool versus alternatives (e.g., 'use this when you have a known source ID'). It is implied by the name and parameter, but no direct guidance 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.

  • Behavior4/5

    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 pagination behavior via limit and offset parameters, and optional filtering, which is good. However, it does not mention read-only nature 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.

    Conciseness4/5

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

    The description is concise with a front-loaded main sentence and structured argument list. It could be slightly more streamlined, but it is effective.

    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 existence of an output schema, the description covers parameter behavior and return type adequately. It lacks details on sorting or error handling, but these are secondary for a list 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 description coverage is 0%, but the description adds meaning beyond the schema by specifying the range for limit (1-100) and explaining offset for pagination. It also clarifies that notebook_id is an optional filter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid 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 all sources with optional filtering', which specifies the verb 'get' and resource 'sources', and distinguishes from sibling tools like get_source (single) and create_source.

    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 sources with optional notebook_id filtering and pagination, but does not provide explicit guidance on when to use this tool versus alternatives like search or get_source.

    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?

    The description explains the behavior: returns a dictionary with notes list and metadata, with pagination via limit and offset. Since no annotations exist, it sufficiently conveys the read-only nature, though could explicitly state 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.

    Conciseness4/5

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

    The description is concise (around 80 words) and structured as a docstring with Args/Returns sections. Some rephrasing could improve clarity, but it is largely effective and front-loaded.

    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 simple list tool with pagination and no output schema, the description covers all necessary aspects: filtering, pagination, return structure. It is complete given the tool's complexity and sibling context.

    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?

    With 0% schema coverage, the description fully compensates by explaining all three parameters: notebook_id filter, limit (1-100), and offset for pagination. This adds crucial meaning beyond the schema's type and default.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid 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 all notes with optional filtering', providing a specific verb and resource that distinguishes it from siblings like get_note (single note) and search (full-text search across sources).

    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 notes with optional filters but does not explicitly state when to use this tool over alternatives such as search or get_note. No exclusions or 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.

  • 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 does not disclose behavioral traits beyond the description (e.g., auth needs, rate limits). The return dictionary is mentioned, but for a search tool this is 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 concise with a single sentence for purpose, followed by clear Args and Returns sections. Every sentence adds value, and the structure is front-loaded.

    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 low complexity (3 optional parameters, output schema exists), the description covers purpose, parameters, and return format completely. No missing details 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.

    Parameters5/5

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

    Schema description coverage is 0%, but the description thoroughly explains all three parameters: query (search query), detail (enum levels), and limit (range 1-50). This adds significant meaning 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 tool searches for tools exposed by the server with progressive detail levels. It uses specific verb 'search' and resource 'tools/capabilities', and distinguishes from sibling 'search' which likely targets other content.

    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 an Args section explaining the parameters and their defaults, providing clear context for usage. However, it does not explicitly mention when not to use this tool versus alternatives like 'search'.

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