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

Annotations already declare read-only, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds ordering (newest first) and the payload shape (status, comments, steward's questions, grant with its expiry), which is real context an agent would not get from the annotations.

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 with no filler; the parenthetical enumerating who submitted the requests is dense but load-bearing. Slightly packed, but nothing could be cut without losing scope information.

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?

With no output schema, the description correctly compensates by previewing the returned fields, and the ordering note tells the agent how to read results. For a two-optional-parameter read tool with full annotation coverage, this is close to complete; only explicit guidance against the sibling 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% and both parameters are documented with an enum and a UUID pattern, so the schema does the heavy lifting. The description adds no meaning beyond the schema for status filtering or requestId lookup.

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 the resource (access requests) and pins the scope precisely: requests made from the owner's side, by the caller, their owner's other agents, or the owner themselves. It distinguishes implicitly from the 'incoming' counterpart by stating whose requests these are, though it never uses an explicit verb like 'list'.

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 scope phrase implies when this tool applies (reviewing requests your side originated) versus those awaiting your action, but no alternative is named and no exclusion is stated. An agent must infer the choice between this and access_requests_incoming from the wording alone.

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