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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so safety is covered. The description adds useful behavior beyond that — newest-first ordering, the contents returned, and the decision-authority boundary — but says nothing about result volume, pagination, or what happens when no requests exist, which matters for a list tool with no 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?

Three short sentences, front-loaded with what is returned and its ordering, then the steward workflow and the decision boundary. There is no filler; the only slight looseness is 'ask questions, then recommend', which is terse enough to be mildly ambiguous about which tools implement it.

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 carries the burden of describing returns and does so (reason, thread, recommendation, newest first). Combined with 100% schema coverage on both optional parameters and full annotation coverage, an agent has enough to call it correctly; only pagination and empty-result behavior are unaddressed.

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 the status enum and the requestId pattern are fully documented in the schema. The description adds no parameter-level meaning (it never mentions the status filter or single-request lookup), so the baseline of 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?

The description gives a specific verb and resource: it lists access requests that people sent to *your owner*, ordered newest first, and names the payload (reason, thread, recommendation). That scope wording implicitly separates it from the 'mine' variant without naming the sibling explicitly, which is the only thing keeping it from a 5.

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 supplies real workflow context: the agent acts as steward, should ask questions and then recommend, and is told explicitly that 'Only your owner decides' — a clear boundary on what the caller must not do. It stops short of naming which sibling to use for commenting versus recommending, so routing is inferred rather than stated.

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