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

With no annotations, the description carries the full burden. It usefully discloses that the enrollment expires after 24 hours and that an enrollment must already exist, but it never states whether verification consumes or invalidates the proof/read_token, whether the call is idempotent, or what happens on an expired enrollment.

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 short sentences, zero filler, with the core action stated first and the expiry caveat second. Nothing needs trimming.

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 two-parameter tool with no annotations, no output schema, and 0% parameter description coverage, the description is too thin: it does not explain what a successful verification returns or means, how the token relates to the enrollment, or the failure modes. The 24-hour note is the only substantive addition.

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% — the schema only supplies a pattern and length bounds with no meaning. The description never mentions enrollment_id or read_token; only the phrase 'previously started enrollment' loosely implies where enrollment_id comes from. The read_token's purpose is entirely undocumented.

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 specific verb ('Verify') and resource ('the exact proof file for a previously started enrollment'), which ties it to enroll_target rather than the other siblings. It does not explicitly distinguish itself from verify_deployment, which also performs a verification, so it falls short of a 5.

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?

There is an implied prerequisite ('previously started enrollment') that tells the agent this must follow enroll_target, and the 24-hour expiry gives a timing constraint. However, there is no explicit when-to-use guidance, no statement of when not to use it, and no naming of the alternative verify_deployment.

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