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

No annotations are provided, so the description carries the full burden and does so well: it discloses the two-pass validation, what Step 1 returns (summary, consent line, confirmation token), the requirement to show the person the summary, the double opt-in email link that must be clicked before any provider sees it, and the literal consent wording. This is exactly the behavioral context an agent needs for a mutating, consent-gated tool.

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?

Front-loaded with the two-step flow and the 'not a purchase' framing before details. It is dense — largely one long sentence with embedded clauses — and the full quoted consent line adds length, but each element (token handling, email double opt-in) earns its place for such a compliance-sensitive tool.

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?

With no annotations and no output schema, the description still conveys the full lifecycle: validation pass, returned summary/token, conditional second call, and recipient email confirmation before provider visibility. An agent has everything needed to invoke both steps 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 coverage is 100%, so the baseline is 3, but the description adds real meaning: it explains that 'answers' is keyed by field key from enquiry_fields, that 'consent' gates Step 1 and means specific agreed wording, and that 'confirmation' is the token returned from Step 1 and passed back only after approval. That is usage semantics beyond the schema text.

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 (submits) and resource (an enquiry to providers), and explicitly negates the likely misreadings: NOT a purchase, NOT a guaranteed quote. The title reinforces the two-step nature. An agent can distinguish this from enquiry_describe and enquiry_fields without opening any schema.

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 when-to-call sequencing: Step 1 with answers and consent=true to validate, Step 2 only if the person agrees, with the same answers plus the confirmation token. It also ties the answers to the enquiry_fields sibling (keyed by field key), so the agent knows the prerequisite tool.

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