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

With no annotations, description fully discloses return fields (valid flag, tier, creation time, slugs, grant) and explicitly states what is never returned (key, email, Stripe session).

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

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

Three sentences, front-loaded with purpose, no redundancy, every sentence adds value.

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

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

Complete for a simple tool with one parameter and no output schema; adequately explains return behavior and constraints.

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

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

Schema has 100% coverage with clear description of api_key parameter; description adds only minor usage context, meeting baseline.

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

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

Clearly states the tool verifies an access key and reports what it unlocks, distinguishing from sibling tools like get_access_info and get_corpus.

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

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

Explicitly recommends use for confirming a freshly-purchased key, implying when to use but not explicitly excluding alternatives.

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

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

No annotations provided, so the description bears full burden. It indicates a read operation ('Return') but offers no details on authentication, rate limits, or what fields are included. Lack of output schema further 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.

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

Single sentence, front-loaded with the verb and resource. Efficient but 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.

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 no parameters, the description is minimal. It lacks details on the format or structure of the returned information, which would help an agent interpret the tool's output.

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

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

No parameters exist, so schema coverage is 100%. The description adds no parameter info, but none is needed. Baseline 4 is appropriate.

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

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

The description clearly states the verb 'Return' and the resource 'access and pricing information for ChangeGamer resources', making the purpose specific. It distinguishes from siblings like check_access and get_pricing by indicating this tool combines both types of information.

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

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. Without explicit context or when-not-to-use instructions, an agent might not know whether to pick this over check_access or get_pricing for combined vs separate info.

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

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

With no annotations provided, the description clearly discloses the tool's behavior: it returns full content for free resources and stubs for premium resources, and notes the large response size. This sufficiently informs the agent of what to expect, though it could mention potential rate limits or timeout considerations.

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

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

The description is three sentences with no waste. The first sentence states the purpose and scope, the second clarifies premium behavior, and the third gives a usage recommendation. It is front-loaded and efficient.

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

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

Given no output schema and no parameters, the description adequately covers what the tool returns and important caveats (large size, premium stubs). It could be slightly more complete by mentioning format details (e.g., that content is in Markdown), but overall it is sufficient 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.

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

The tool has no parameters, and the schema coverage is 100% (vacuously). The description adds value by explaining what the single output contains and how the response is structured, which is beyond the schema's empty definition.

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

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

The description clearly states the tool returns the entire free corpus as one document, specifying exactly what is included (titles, descriptions, URLs, full Markdown bodies) and how premium resources are handled (stubs with purchase links). This distinguishes it from siblings like get_resource or list_resources, which have narrower scopes.

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

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

The description explicitly advises using this tool to 'ingest everything in a single call' and warns that 'the response is large', providing clear usage context. It does not explicitly state when not to use it, but the existence of siblings like get_resource implies alternatives for targeted access.

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

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

With no annotations, description fully discloses authentication requirements, potential upgrade object return, and that it's a single document. Includes key format (cg_...).

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

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

Three sentences, front-loaded with purpose, then conditions. No unnecessary words; every sentence earns its place.

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

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

Given only one parameter and no output schema, the description covers purpose, prerequisites, failure case, and alternative tool, making it complete for effective use.

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

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

Schema already describes api_key as 'Corpus/Enterprise license key (cg_...)', but description adds context about entitlement requirements, Starter key insufficiency, and failure mode. Adds value beyond schema.

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

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

Description clearly states it returns the entire corpus including premium resource bodies, identifies it as the key deliverable of the Corpus/Enterprise license, and distinguishes from sibling get_corpus (free, premium-stubbed version).

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

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

Explicitly specifies when to use (Corpus/Enterprise key required), what happens if not entitled (payment-required object returned), and mentions alternative get_corpus for free access.

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

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

With no annotations, the description fully carries the burden. It clearly indicates a read-only operation by stating it 'returns' data and references a JSON endpoint. No destructive or side effects are implied, and the mention of the retry loop adds transparency about potential HTTP behavior.

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

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

The description is two sentences, front-loading the core purpose in the first sentence and adding a reference for consistency in the second. Every word is informative with no redundancy.

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

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 self-contained. It covers all relevant aspects: payment methods, retry loop, free items, recommendations, and data source. Nothing essential is missing.

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

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

The tool has zero parameters, so schema coverage is 100% and no parameter documentation is needed. The description adds value by explaining what the output contains, which is beyond the schema's empty scope.

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

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

The description explicitly states the tool returns the agent payment manifest, detailing payment methods, retry loop, free items, and recommended paths. It distinguishes from siblings like 'get_pricing' by focusing on the full payment manifest and referencing a specific API endpoint.

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

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

The description implies use for exploring payment options and provides a recommended path per use case. However, it does not explicitly contrast with sibling tools like 'get_pricing' or 'check_access', missing some clarity on when to choose 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.

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

With no annotations provided, the description carries the full burden. It explicitly lists the return elements (tiers, price, currency, interval, etc.) and notes it's the same as /api/pricing.json. However, it does not disclose whether the data is cached or if it requires authentication, but for a read-only, zero-parameter tool, the behavioral detail is sufficient.

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

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

Two concise sentences that front-load the main purpose and provide a helpful reference to the equivalent API endpoint. No wasted words; every sentence adds value.

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

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

Given no output schema, the description compensates by enumerating the return fields (price, currency, interval, etc.). It could mention that the data is static or note any limitations, but for a simple catalog tool, it is largely complete. The sibling list is provided but not differentiated, which is acceptable.

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

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

There are no parameters in the input schema, so the description has no need to add parameter semantics. Baseline 4 applies since the schema coverage is 100% and no parameters exist. The description correctly omits parameter details.

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

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

The description clearly states the tool returns the full paid-offer catalog with specific details (price, currency, interval, etc.). It distinguishes itself from siblings by noting it provides the same data as /api/pricing.json, making the purpose unmistakable.

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

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

The description implies usage for obtaining the complete pricing catalog, similar to a specific API endpoint. While it doesn't explicitly state when not to use it or provide alternatives, the context of siblings like get_payment_info suggests this is for the full catalog rather than individual records. Clear but lacks explicit exclusions.

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

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

With no annotations, the description carries full burden. It discloses key behaviors: free resources return full metadata and Markdown body, premium resources require a valid api_key, and without it a payment-required object is returned. This adds value beyond the schema, though it omits error handling and response structure details.

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

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

Two sentences, no unnecessary words. The information is front-loaded and each sentence is essential.

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

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

Given the conditional behavior and no output schema, the description adequately explains the two cases (free/premium). It doesn't include error scenarios or explicitly reference sibling tools, but the provided information is sufficient for basic usage.

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

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 behavior context for the api_key parameter, explaining its role and consequences of omission, which is valuable beyond the schema's simple description.

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

Does the description clearly state what the 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.

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 you have a slug) and provides context for free vs premium resources. However, it does not explicitly mention alternatives or when not to use it, relying on the distinct slug parameter for differentiation.

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

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

With no annotations, the description carries the full burden. It describes the return data and references the /api/stats.json endpoint, implying it's a lightweight read operation. However, it does not disclose potential side effects, authentication requirements, rate limits, or any other behavioral traits beyond the data summary.

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

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

The description is two sentences, front-loaded with the return data, and a clear use case in the second sentence. No wasted words; every sentence earns its place.

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

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

For a zero-parameter stats tool without output schema, the description is quite complete: it lists all return fields, provides usage guidance, and gives a reference endpoint. Missing details like pagination or auth are minor given the simplicity.

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

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). Baseline is 4 per rubric. The description adds value by listing the specific metrics returned, going beyond the empty schema.

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

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

The description clearly states it returns corpus stats with a specific list of items (counts, dates, recent resources, feed URLs). The verb 'Return' is clear. However, it does not explicitly differentiate from sibling tools like get_corpus or get_full_corpus, though the stat focus is implicit.

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

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

The description explicitly says 'A small freshness/size signal to poll before deciding whether to re-ingest,' providing clear context for when to use this tool. It doesn't exclude alternatives but gives a specific use case.

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

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

Provides key behavioral trait: 'No body content' and lists returned fields, but lacks detail on pagination, sorting, auth requirements, or limits. No annotations provided 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.

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

Two concise sentences with front-loaded main action and efficient listing of returns; no redundant words.

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

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

Complete enough for a parameterless list tool with explicit field listing, but lacks optional details on ordering or error handling.

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

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

No parameters exist; description adds meaning by detailing what the tool returns (slug, title, URLs, etc.), compensating for absence of output schema.

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

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

Clearly states 'List all ChangeGamer resources', specifies the verb and resource scope, and distinguishes from siblings like get_resource (singular) and search_resources (filtered).

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

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

The description covers purpose, output, and usage guidance. With two parameters fully described in schema and no output schema needed, the description is fairly complete. It could mention that results are ranked by relevance, but that is implied by 'ranks resources by relevance'.

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

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 with example keywords for the query parameter, but limit's description is already covered by schema. The examples help an agent form effective queries.

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

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

The description uses the specific verb 'Search' and resource 'ChangeGamer corpus', and details that it ranks by relevance across multiple fields and returns metadata with URLs. This clearly distinguishes it from sibling tools like get_resource (fetches content) and list_resources (likely without keyword search).

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

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