Pickleball3 Paddle Catalog

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

Description adds behavioral traits beyond annotations: it guarantees no fabricated measurements and no personalization, which aligns with readOnly and idempotent hints. This provides useful context about the tool's limitations, though it lacks details on output format.

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

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

The description is a single, front-loaded sentence with no wasted words. Every part contributes meaning: 'compare', 'two to four', 'exact public paddles', and the exclusion clause. It is highly concise 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 the absence of an output schema and only one parameter, the description adequately states the purpose but fails to describe the return value or provide parameter semantics. It is minimally complete for a simple read-only tool, but could be more informative.

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?

With 0% schema description coverage, the description does not explain the 'slugs' parameter (what it represents or how to obtain them). The name alone is insufficient for an agent to correctly use the parameter, leaving a significant gap in understanding.

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 compares two to four exact public paddles, with a specific verb 'compare' and resource 'paddles'. It distinguishes from siblings by explicitly excluding personalized recommendation or inventing measurements, setting it apart from search or recommendation 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 provides context by specifying 'exact public paddles' and ruling out personalized recommendations, which implies when to use this tool versus alternatives. However, it does not explicitly name sibling tools or state when not to use it, missing clear exclusion guidance.

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?

Annotations already indicate read-only, idempotent, non-destructive behavior. The description adds value by detailing the return content (scores, metrics, citations, link) and confirming it returns one exact record. No contradictions.

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

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

The description is a single, well-front-loaded sentence with no wasted words. It efficiently conveys the tool's purpose and return content.

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 lists return components but does not explain output structure (e.g., format, nesting), error cases, or what happens if slug is invalid. Partially complete given the tool's simplicity and missing output schema.

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?

With 0% schema description coverage, the description should explain the 'slug' parameter. It only implies it is the identifier for the paddle record, without specifying format or source. Minimal added meaning.

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 'Get', the resource 'one exact public paddle record', and includes specifics like scores, metrics, citations, and a sponsored link. It distinguishes from siblings such as 'search_paddles' and 'compare_paddles'.

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 does not explicitly state when to use this tool vs alternatives. It implies it is for retrieving a single record by slug but offers no guidance on when to prefer this over search or comparison tools.

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?

The annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is clear. The description adds the behavioral trait 'current snapshot', indicating a static point-in-time view, which is valuable context beyond the annotations.

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 a single, well-structured sentence that front-loads the verb 'list' and immediately states the resource. No extraneous words or repetitions.

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 simple listing tool with no parameters and no output schema, the description adequately covers what it returns (brand names and review counts) and that it's a snapshot. It could mention ordering or size limits, but is complete enough for most use cases.

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, and the schema coverage is 100% (trivially). Baseline for 0 parameters is 4. The description does not need to explain parameters, so the score 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 uses a specific verb 'list' and clearly identifies the resource as 'normalized brand names and public review counts'. It also specifies 'in the current snapshot', which adds temporal context. This clearly distinguishes it from sibling tools like 'search_paddles' (filtered) and 'get_paddle' (single item).

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 does not explicitly state when to use this tool versus alternatives. While the name and sibling names imply this is for browsing all brands, no when-not or alternative guidance is provided. It meets a minimum adequacy but lacks explicit 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?

Annotations already indicate read-only, idempotent, and non-destructive behavior. The description adds that results are deterministic and filtered, and clarifies purchase link conditions, providing extra context.

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, each adding value. No wasted 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?

Given 9 undocumented parameters and no output schema, the description fails to provide sufficient context for correct usage, such as pagination or filter semantics.

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 0%. The description does not explain any of the 9 parameters (sort, year, brand, limit, query, offset, max_score, min_score, has_purchase_link), leaving the agent to infer from names and constraints.

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 searches the Pickleball3 paddle catalog with deterministic bounded filters, distinguishing it from sibling tools like compare_paddles and get_paddle.

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 mentions purchase links appear only for exact-model verified sponsored URLs, but lacks explicit guidance on when to use this tool versus siblings.

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