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

With no annotations provided, the description carries the full behavioral burden and does so well: it discloses the two-step validation/submission flow, the email verification gate, the exact consent meaning, and the fact that the enquiry is not a purchase or guaranteed quote. It adds important context beyond the schema without contradicting any structured metadata.

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 core purpose and negative constraints, then organized into clear Step 1 and Step 2 instructions. Despite its length, every sentence contributes necessary workflow or consent information for a two-step submission 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?

Given the two-step consent flow, nested answers object, and absence of an output schema, the description supplies what an agent needs: return behavior for step 1, submission behavior for step 2, consent wording, and the email verification requirement. No critical caller guidance appears to be missing.

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 schema already documents all three parameters, but the description adds procedural meaning: answers are keyed by field key from enquiry_fields, consent must be true only after agreement, and confirmation is the token returned from step 1 after approval. The added context is useful but overlaps substantially with schema parameter descriptions.

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 specific verb and resource — submitting an enquiry to human providers — and immediately clarifies that it is not a purchase or guaranteed quote. It is clearly distinguishable from sibling tools such as enquiry_fields and the compare_* tools by its submission/consent workflow.

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?

It gives explicit, sequential guidance: step 1 validates and returns a summary plus token, and step 2 is only called if the person agrees, using the same answers and the token. It also tells the agent to show the person the summary and consent line, and explains that an email link must be clicked before providers see the enquiry.

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