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

Annotations already declare readOnlyHint=false, destructiveHint=false and idempotentHint=false. The description adds one genuinely useful behavioral fact beyond them — done=true closes the task, a terminal state change despite the non-destructive hint. It leaves open what happens to the task after a plain release (returned to the queue?), whether the operation is reversible, and whether ownership of the claim is required.

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 sentence that front-loads the primary action and appends the completion variant with its consequence in parentheses. There is no filler, and the parenthetical earns its place by flagging a state transition.

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 five parameters, one required and all schema-documented, plus no output schema, the description is just barely sufficient. It does not explain what the returned result looks like, whether note is expected when closing, or what allowTerms does, which matters for an agent deciding how to fill a five-field call.

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 coverage is 100%, so every parameter is already documented and the baseline is 3. The description restates the meaning of done ('closes the task') without adding anything the schema does not already say, and it says nothing about note, git, or allowTerms — notably not clarifying that allowTerms exists to clear a privacy filter on outbound 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 gives a concrete verb phrase ('Give up a claim') against a specific resource and pairs it with the completion branch ('finish it with done=true'). It clearly distinguishes the release action from claiming without needing to open the schema, though it never names claim_task as the counterpart operation.

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?

Usage is implied through the two-mode framing: abandon a claim, or complete the task via done=true. There is no explicit statement of prerequisites (e.g. that the caller must currently hold the claim) and no reference to a sibling tool such as claim_task or work_queue as the alternative path, so the guidance stays implicit rather than instructive.

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