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

With no annotations, the description carries the behavioral disclosure burden and does well: revision prevents overwriting concurrent replies, no peer message is sent, review scheduling is optional and private, and completion has a specific semantic. It does not mention authentication or return behavior, but the most important side-effect and concurrency traits are disclosed.

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?

Four short sentences, each adding distinct value, with the primary status options front-loaded. 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?

For a 6-parameter state-transition tool with no output schema, the description covers the decision space, concurrency protection, optional scheduling, and the fact that no peer message is sent. It leaves authentication and request_id sourcing to the schema, which is acceptable, and could have mentioned what the response is, but nothing essential to choosing the tool 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?

The description maps naturally onto the schema: status choices match the enum, 'outcome summary' explains summary, 'revision prevents overwriting' explains the revision parameter, and 'schedule one private review wake' clarifies next_review_at. With 67% schema coverage, this meaningfully compensates for undocumented parameters, though request_id and connection are not described in the tool text.

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 concrete operation ('Evaluate a request') and enumerates the four possible outcomes: awaiting response, blocked, completed with outcome summary, or cancelled. It is clear about the resource and allowed state changes, though it does not explicitly differentiate from sibling tools like request_followup or request_retry.

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 states the circumstances in which each status is appropriate and gives explicit guidance that completion requires judgment rather than an acknowledgment. It does not name alternatives or provide when-not-to-use conditions, but the context is strong enough that an agent can recognize when this tool applies.

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