claim_release

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

Annotations already declare readOnlyHint=false (write operation) and destructiveHint=false (not destructive). The description adds the guard behavior of sessionId, which is beyond annotations. However, it does not disclose failure modes (e.g., releasing a non-existent claim, mismatched sessionId) or idempotency, so it only partially fulfills the burden.

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?

Two sentences with no extraneous words. The core purpose is front-loaded, and the security-relevant detail about sessionId follows naturally. Efficient and well-structured.

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 simple mutation tool with no output schema, the description is missing success/failure behavior (e.g., what happens on successful release or if the claim is not found). It also does not mention prerequisites like having acquired the claim, though this is implied by the sibling claim_acquire. These gaps reduce completeness.

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 0%, so the description must compensate. It explains the purpose of sessionId but not claimId beyond its name. Given the tool's context, claimId is reasonably self-explanatory, but the description does not fully define both parameters, leaving a partial gap.

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 clearly states the action ('Release a durable resource claim') with a specific verb and resource. It also adds a distinguishing nuance about sessionId preventing cross-agent release, which helps differentiate from claim_acquire and claim_list without naming them explicitly.

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?

The description implies when to use the tool (when releasing a claim) but does not explicitly contrast with claim_acquire or mention when not to use it. The sessionId guidance is useful for safe usage, but there is no explicit alternative routing or exclusion criteria.

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