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

The annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint, so the safety profile is covered. The description adds useful behavioral detail beyond annotations: the result is 'terminal,' 'standalone,' and includes a 'short-lived download URL,' which signals expiration. It does not mention authentication or rate limits.

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 that communicates the action, the result type, and an important return characteristic without any wasted words.

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 one-parameter read-only tool with full schema coverage and annotations, the description is nearly complete. It states what is returned (receipt and short-lived download URL) even though there is no output schema, though it could better relate this tool to verification_status or verify_citations.

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 the single parameter verification_id is documented in the schema as 'A verification id returned by verify_citations.' The description adds no further parameter syntax or constraints, so the baseline 3 is appropriate when the schema carries the semantics.

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: 'Get a terminal standalone verification receipt.' The qualifiers 'terminal' and 'standalone' and the mention of a 'short-lived download URL' make the purpose clear, but it does not explicitly distinguish itself from the sibling tool verification_status.

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 word 'terminal' implies the tool should be used after a verification has reached a terminal state, and the mention of a receipt implies when a downloadable record is needed. However, there is no explicit guidance about when to use this versus verification_status or verify_citations, so usage is only implied.

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