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 well: it discloses that step 1 only validates, that a confirmation token is required for the actual write, that the person must click an email link before any provider sees the data, and that details go to up to three firms. It stops short of stating idempotency, rate limits, or token expiry, so a 4 rather than 5.

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 negative scope, then the two steps in order, each sentence earning its place. Slightly long because the full consent sentence is reproduced verbatim (already present in the schema's consent description), which is mild redundancy.

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?

For a nested-object, two-step submission tool with no output schema and no annotations, the description supplies everything needed: what is returned (summary, consent line, token), what to show the user, when to make the second call, and what happens after submission.

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 already 100%, so the baseline is 3, but the description adds real cross-parameter semantics: answers must be keyed by the field keys from enquiry_fields, consent must be true, and confirmation is only supplied on the second call after approval. That sequencing meaning is not derivable from the schema alone.

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 Private Label Manufacturers') and immediately scopes it negatively with 'NOT a purchase, NOT a guaranteed quote.' This distinguishes it from the describe/fields siblings, which merely supply input data rather than submitting anything.

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 an explicit two-step protocol: Step 1 call with answers+consent=true to validate and get a token, Step 2 only after the person agrees, with the token. It also names the dependency on enquiry_fields for the answer keys and states the precondition (person must have read and agreed to the consent text).

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