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

With no annotations, the description carries the full behavioral burden and does so well: it indicates a read-like list operation, defines ordering, declares the returned fields, states that codes are never included, discloses an auth failure mode, and notes the tool is free. This is strong added context beyond any structured metadata.

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 about 60 words and every sentence earns its place: scope/order/filter, output fields, exclusion of codes, and auth/pricing. Information is front-loaded and there is no filler or repetition.

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 output schema exists and the description already enumerates returned fields, the definition covers ordering, filtering, output contents, auth requirements, and cost. The only notable gap is the undocumented api_key parameter, which an agent may need clarified to call the tool correctly.

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 0%, so the description must compensate. It clearly defines the status parameter's allowed values (pending, approved, rejected) and optionality, which adds real meaning beyond the bare schema. However, the api_key parameter is never mentioned in the description, leaving its format, purpose, and relation to the admin requirement implicit.

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 names a specific verb and resource: listing every access request, with ordering (newest first) and an optional status filter. This clearly distinguishes it from sibling tools like list_access_codes or request_access, so an agent can select it without ambiguity.

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 gives explicit preconditions: owner only, admin scope required, and an admin account, including the resulting 403 error if unmet. It does not explicitly name alternative tools for related actions (e.g., approve_access_request), but the use context is clear enough for correct selection.

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