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

With no annotations, the description carries the full burden and does so: it discloses that step 1 only validates and returns a summary/consent line/token, that step 2 actually submits, that an email confirmation link must be clicked before any provider sees the enquiry, and the exact scope of consent (up to three providers, emailed per firm, can stop). That is unusually rich behavioral disclosure for a mutation 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?

The description is front-loaded with the key constraint ('NOT a purchase, NOT a guaranteed quote') and proceeds through the two steps in order with no filler. It loses a point for reproducing the full consent sentence verbatim, which already appears in the consent parameter's schema description.

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, and the description compensates by naming what step 1 returns (summary, consent line, confirmation token) and what step 2 triggers (submission plus a confirmation email). For a nested-object, two-phase tool, nothing an agent needs in order to call it correctly is 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 baseline is 3, but the description adds real meaning beyond the schema: 'answers' is keyed by field key from enquiry_fields, 'consent' must be true only on agreement, and 'confirmation' is the step-1 token used only after approval. The two-step role of the confirmation parameter is workflow semantics the schema cannot express.

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 ('Submits an enquiry to Gearbox Reconditioning Cost') and immediately bounds the scope with 'NOT a purchase, NOT a guaranteed quote'. It also cross-references the sibling tool enquiry_fields for the answer keys, so an agent can place it relative to its siblings without opening a 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?

It gives an explicit two-step procedure with the exact condition gating each call: step 1 with answers+consent=true, step 2 only after the person agrees and with the confirmation token. The when-not (not a purchase, not a guaranteed quote) and the human-approval gate are stated outright.

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