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

With no annotations, the description carries the full behavioral burden and does so well: it discloses validation behavior, what step 1 returns (summary, consent line, token), that the second call is irreversible submission, and that contact details go to up to three providers who may contact the person directly. The one gap is that it doesn't state what happens if step 2 is called without a valid token, or whether submission can be undone.

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?

Well front-loaded: the 'NOT a purchase' warning and the step split come first, so an agent gets the critical framing immediately. It is somewhat long, and the full consent sentence is duplicated verbatim from the schema's consent description, which is mild redundancy, but every other sentence carries operational information.

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?

No output schema exists, and the description compensates by describing what step 1 returns (summary, consent line, token) and what step 2 triggers (submission plus a verification email). Combined with a fully documented schema, an agent has everything needed to drive both calls correctly.

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%, so the baseline is 3. The description goes beyond it by explaining that answers are keyed by the field keys returned from enquiry_fields, that consent must be true at both steps, and that confirmation is the token issued by step 1 — usage semantics the schema alone doesn't convey.

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?

States a specific verb and resource (submits an enquiry to human providers) and immediately delimits scope with 'NOT a purchase, NOT a guaranteed quote'. The two-step framing and the reference to enquiry_fields answers distinguishes it cleanly from the sibling read tools enquiry_describe and enquiry_fields.

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?

Gives explicit staged conditions: Step 1 calls with answers + consent=true, Step 2 only if the person agrees and with the confirmation token. It also states prerequisites (person must have read and agreed to the consent text) and the downstream gate (recipient must click an emailed link before any provider sees the enquiry). Nothing about when to call vs. not call is left to inference.

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