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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states an authorization prerequisite but does not explain mutation side effects, authentication requirements, idempotency, what happens if the checkpoint is already claimed, or error behavior for a claim operation.

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?

The description is a single front-loaded sentence with no wasted text. The prerequisite clause follows immediately after the action, making it easy to parse.

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 claim operation with no annotations, no output schema, and zero schema description coverage across four parameters, the description is too sparse. It covers the core action and one authorization condition but leaves key parameter meanings and behavioral details unspecified.

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 for all four parameters. It only indirectly hints at provider_authorization_confirmed and contributor legitimacy, while task_id and note remain completely unexplained.

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 states a specific verb and resource: 'Claim a KYC checkpoint'. It is clear what the tool does, but it does not explicitly distinguish this tool from siblings such as human_kyc_complete or human_kyc_reconcile.

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 provides an implied usage condition: claim after confirming provider rules permit the contributor to be the legitimate claimant/payee/contractor. However, it gives no explicit guidance on when to use this tool versus sibling KYC tools or what conditions should prevent use.

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