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

No annotations are provided, but the description discloses the return content in detail, indicating a read-only lookup with no side effects. It does not mention error behavior or rate limits, but for a straightforward retrieval of an OpenAPI object, the transparency is adequate.

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: the first states what is returned, the second specifies when to use it. No wasted words; the most important information is front-loaded.

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 the components of the returned OpenAPI object and provides usage context relative to search_endpoints. The schema covers parameters. Since there is no output schema, the description's enumeration of return contents helps complete the picture, though it could mention error 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?

Schema coverage is 100%, with both path and method having descriptive comments including an example path and default method. The description adds no parameter details beyond the schema, so the baseline score of 3 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 tool returns the full OpenAPI operation object for a given path, listing specific contents (parameters, request body, response schemas, examples, tags). This specific verb+resource phrasing distinguishes it from siblings like search_endpoints and list_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?

It explicitly instructs to use this tool after search_endpoints to drill into a specific endpoint, providing clear contextual usage and implying an alternative tool for the search step. This is strong guidance.

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