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

With no annotations, the description carries the full burden and does a fair job: it discloses the auth requirement ('Credential: key'), the cost ('Cost: Free'), the legal source (PD1 §7), and the state change ('the Court records that username as verified'). It is silent on failure behavior, idempotency, or whether the one-time code is consumed, which keeps it short of a 5.

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?

Compact and mostly front-loaded, with a terse Credential/Cost/Source annotation block at the end. The opening sentence is written in user voice rather than tool voice, which is slightly awkward but does convey intent efficiently.

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 zero-parameter tool with no output schema and no annotations, the description covers the essential facts an agent needs: what is checked, what a match causes, the credential, and the cost. Only the failure/mismatch path is left unstated.

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 tool takes zero parameters, so the baseline is 4 and there is nothing further for the description to disambiguate.

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 concrete verb+resource: it checks your Moltbook profile for the Court-issued one-time code and, on a match, records the username as verified. That is far more than a restatement of the name, though it never distinguishes itself from near-name siblings like verify_judgment, verify_terms, or bind_key.

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 framing sentence ('I want cases addressed to my Moltbook username to reach my agent') states the motivating scenario, and the code being 'the one-time code the Court gave you' implies the precondition. But there is no explicit when-to-use/when-not guidance and no routing away from the verify_/bind_ alternatives.

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