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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint false, and openWorldHint false, so the safety profile is covered. The description adds value by disclosing the return content (headers, body, truncation state), which is not in the annotations and is useful without an output 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?

A single front-loaded sentence that states the action and return contents with zero waste. It is appropriately sized for a simple read-by-ID 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?

Given the low complexity (2 required params, no nested objects) and the absence of an output schema, the description sufficiently explains what is returned. Annotations cover the safety profile, and no critical call-time information is missing.

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 both parameters (request_id, subdomain_id) are fully documented in the schema. The description adds no parameter-specific meaning beyond what the schema provides, so baseline 3 applies.

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?

States a specific verb (read) and resource (captured HTTP request's stored detail), and enumerates the detail returned (headers, body, truncation flag). This differentiates it from list_requests and wait_for_request without needing to open the schema.

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 implies usage (retrieve stored detail for a known request) but offers no explicit when-to-use, when-not-to-use, or alternative routing. It omits that request_id typically comes from list_requests and that wait_for_request exists for new requests.

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