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

No annotations are provided, so the description carries the full behavioral burden. It does this well by disclosing that the first call does not submit, that a confirmation token is required for the real submission, that an email with a click-link is sent, and that providers only see the enquiry after that click. It also discloses the exact consent wording and that this is not a purchase or quote.

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 long but every clause carries necessary operational information. It front-loads the core purpose and non-purchase disclaimer, then organizes the two steps explicitly. The length is justified by the tool's genuine procedural complexity.

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?

There is no output schema, so the description correctly explains the step-1 return values (summary, consent line, confirmation token) and the final outcome (submission, email, link click, provider visibility). It also references enquiry_fields for answer keys, completing the contextual picture for an agent using the 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?

Schema coverage is 100%, and the description goes further: it explains that answers must be keyed by field key from enquiry_fields, that consent is only true when the person agrees to the exact consent text, and that the confirmation token comes from step 1 and enables the final submission. This meaningfully enriches the schema definitions.

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?

Describes a specific action — submitting an enquiry — and clearly distinguishes it from a purchase or guaranteed quote. The title and description together make it obvious this is not one of the comparison tools or the enquiry_fields descriptive tool.

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?

Provides an explicit two-step invocation sequence: step 1 validates and returns a token, step 2 submits only after person agrees and the token is supplied. It also states the condition for proceeding ('only if the person agrees') and notes the email-link requirement, so the agent knows when and how to call the tool.

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