stats_most_collected_v1

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

With no annotations, the description carries the full burden of disclosing behavior. It only mentions the HTTP method (GET) and API key requirement, but does not describe return format, pagination, error behavior, or confirm that it is read-only. The behavioral traits are largely undisclosed.

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 concise and front-loaded with the endpoint and method. It efficiently lists auth requirements and guide availability. The only minor redundancy is 'Most Collected' repeating the name, but overall it is well-structured and without 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?

The tool lacks an output schema and annotations, and the description does not explain what the response contains or how to interpret the stats. It fails to differentiate among sibling stats tools, though it does point to a guide for full instructions. This is insufficient for confident invocation.

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 'no additional required parameters,' but this is already evident from the schema's all-optional properties. It does not provide endpoint-specific parameter documentation, leaving the generic query/pathParams ambiguous.

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 only states 'Most Collected' which is essentially a restatement of the endpoint name. It lacks a specific verb like 'retrieve' or 'list' and does not clarify that it returns the most-collected games, making it vague and indistinguishable from sibling stats endpoints.

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 authentication requirements and a pointer to a guide resource, but gives no guidance on when to use this tool versus the sibling stats tools (e.g., stats_most_popular_v1, stats_most_waitlisted_v1). No exclusions or alternative recommendations are mentioned.

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