get_golf_club_stats

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

Annotations only supply readOnlyHint/openWorldHint, and the description adds genuinely useful behavior: the default limit of 1000, positive-value validation, and the verified fact that the response is a JSON array of 17 club objects with named fields rather than a single object. That live-verified array disclosure is exactly the kind of trait annotations cannot convey. It loses a point for implementation trivia (raw URL path) and for referencing per-page/include-stats query params that are not exposed in the schema.

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

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

The array-shape warning is bolded and front-loadable, which is good, but the sentence is a semicolon-chained block mixing relevant caller-facing facts (default, return type) with low-value implementation detail (the raw endpoint path). The endpoint URL in particular does not help an agent decide or call the tool.

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 output schema, the description does the right thing by documenting the returned array's field set, and it covers the lone parameter. What is missing is any framing of what these club stats represent, when the data is meaningful, or how this differs from get_golf_user_stats/get_golf_summary, so the agent has return structure but no context for selecting or interpreting the call.

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 single parameter has zero schema description coverage, so the description carries the burden, and it does state the default (limit=1000) and that it is validated positive. It is docked for also describing per-page and include-stats query parameters that do not exist in the input schema, which muddies rather than clarifies what can actually be passed.

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 implies the tool fetches golf club entries by documenting the endpoint path and the array of club objects returned, but it never states a plain verb+resource purpose like 'retrieve golf club statistics'. It also does nothing to distinguish itself from close siblings get_golf_user_stats, get_golf_summary, and get_golf_scorecard, leaving the agent to guess from the name alone.

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?

There is no when-to-use guidance, no prerequisites, and no named alternatives. The agent learns the wire format but not the circumstances that should make it pick this tool over the other four golf tools in the sibling list.

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