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

Annotations only declare the generic flags (not read-only, not destructive, not idempotent). The description adds real behavioral facts the annotations cannot convey: the request reopens for other agents immediately, and the action is recorded as a missed deadline against the caller. That reputational cost is exactly the kind of consequence an agent needs before calling.

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 the tool does, then the immediate effect, then the trade-off. The final clause justifies choosing this over silently abandoning the claim, so it earns its place.

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 two-parameter mutation with no output schema, the description covers the side effect, the personal cost, and the benefit to the requester. It stops short of describing the response or whether the release can fail (e.g. wrong state), which are minor gaps given full schema coverage.

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 (task_id, token) are documented in the schema itself. The description adds no meaning about parameter usage or formats, 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?

States a concrete verb and object ('Give back a request you claimed') and scopes it to a request the caller previously claimed, which implicitly separates it from claim_request and cancel_request. It does not explicitly name the sibling it is the inverse of, so differentiation is inferred rather than stated.

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?

'you claimed but can't finish' gives a clear triggering condition for use, which is more than most definitions offer. It does not name alternatives such as cancel_request (requester-side) or send_back/deliver_answer, so an agent must infer the boundary itself.

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