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

With no annotations, the description must carry behavioral disclosure. It does disclose authentication requirements (API key and specific env vars) and directs users to a guide for full details. However, it does not disclose the operation's side effects, input expectations beyond 'body,' response format, or any rate limits, leaving significant opacity.

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 very short and gets to the point, but the 'Prices' label is redundant filler. The auth and guide pointer are useful, but the mixed-language structure and lack of a clear purpose statement reduce readability.

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 POST endpoint requiring a body with no output schema and rich sibling context, the description is insufficient. It points to an external guide for full detail, but an agent would need to dereference that resource to understand the request payload, expected behavior, and response, making it incomplete for standalone selection and 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?

Although schema coverage is marked 100%, the property descriptions are generic; the 'body' is described merely as a mandatory request body with no content details. The description adds nothing beyond restating the requirement for body and API key, and does not help an agent construct the body or query parameters.

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 states the HTTP method and path, and labels the resource as 'Prices,' but does not explain what prices are returned, for which games, or how the endpoint behaves. This is tautological with the tool name and does not differentiate from sibling price-related 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?

There is no guidance about when to use this tool vs alternatives such as games_info_v2 or games_history_v2. The only usage-related note is that body is required and an API key is needed, which is not a usage scenario.

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