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

The description is consistent with the readOnlyHint annotation and adds contextual scope: results are limited to pending requests and the caller's own grant versions. It does not add deeper behavioral detail like pagination, ordering, or permission requirements, but the annotation already covers the read-only safety profile.

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 a single, efficient sentence with no filler. The key action and scope are front-loaded, and every word adds meaning.

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 is simple, but the required 'id' parameter is completely undocumented in both the schema and the description. With no output schema and no parameter meaning, the agent cannot reliably construct a correct 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?

The schema has 0% description coverage for the single 'id' parameter, and the tool description does not mention 'id' at all. An agent cannot determine whether the id refers to a case, an access request, an evidence item, or something else.

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 uses a specific verb ('inspect') and names the exact resource: pending access requests and the caller's own grant versions. It clearly distinguishes this from sibling tools like grant_case_access and request_case_access.

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 identifies the intended actor ('Evidence owners') and the circumstance (inspecting pending access requests), which gives useful usage context. It does not explicitly state exclusions or name alternatives, but the audience and scope are clear enough for most selection decisions.

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