release_task

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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered. The description adds genuinely new context beyond those hints: the lock is exclusive, it is acquired via checkout_task, and it self-releases on expiry (meaning the call is not always required). It stops short of describing behavior when no lock is held.

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 with the core action front-loaded, followed by the trigger condition and then the auto-expiry caveat. Every sentence earns its place with no repetition of the schema or annotations.

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 single-parameter lock-release tool whose annotations already cover destructiveness and idempotency, and with no output schema to explain, the description supplies everything an agent needs: what it does, when to call it, and the fact that the lock may already be gone via expiry.

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% for the single task_id parameter, so the schema already carries the parameter documentation. The description only implies that task_id refers to a task previously checked out, adding no syntax, format, or constraint detail beyond the schema — the baseline 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 specific verb and resource — releasing the exclusive lock on a task — and ties it directly to the acquiring sibling checkout_task. An agent can immediately distinguish this from the many other task-mutating siblings in the 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?

Explicitly gives the triggering conditions: 'when done with the task or if you need to hand it off,' and names checkout_task as the counterpart that acquired the lock. It does not spell out failure modes (e.g., calling it without holding the lock), but the when-to-use context is clear and actionable.

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