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

With readOnlyHint already set true, the description adds valuable behavioral context beyond annotations: no token required, no auth required, the two access paths, the id-alone failure mode, the consistent found:false result for any invalid input, and the explicit non-return of stored answers or reviewer notes. No contradiction with annotations.

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 front-loaded with the most important fact: 'your own, never anybody else's', and the structural Arg/Return framing at the end helps parseability. It is verbose by strict standards, with a couple of repeated ideas ('No token required' and 'No auth required'; id-alone warnings appear twice), though the repetition is used to reinforce a critical security rule.

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?

Given there is no output schema, the description adequately explains the return shape and semantics: { ok, found, submission? }, what submission contains (status, dates, failed gates), and what it never contains. The security model and both invocation modes are fully spelled out for a security-sensitive tool.

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?

The schema has 100% description coverage, so baseline value is already met. The description adds meaningful semantic context beyond the schema: the relationship between claim_token and submission_id, the 'id alone never works' constraint, and the security rationale. This elevates it above a bare schema readout.

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 uses a specific verb and resource: it reads the status of one submission and 'never anybody else's'. It clearly distinguishes itself from general form/submission tools by emphasizing the own-submission-only behavior and the identity/token mechanisms.

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 gives explicit when-to-use conditions: signed-in identity resolves the record with no id, or submission_id plus claim_token opens the record. It also gives when-not guidance: an id alone never works, wrong tokens all return found:false, and the tool cannot be used to test which ids exist.

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