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 validation behavior on step 1, the returned artifacts (summary, consent line, confirmation token), that submission is not final until the person clicks an emailed link, and the exact scope of consent (up to three solicitors, notified per firm, stoppable). No contradictions to reconcile.

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 core distinction (enquiry, not purchase) before the procedural detail, and the two steps are cleanly sequenced. The verbatim repetition of the consent sentence already present in the schema costs it a point, but nothing else is padding.

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 must cover returns — and it names all three (summary, consent line, confirmation token) plus the asynchronous email step. For a nested-object, token-gated, two-call tool, this is complete enough to invoke 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 meaning the schema cannot: it explains where the confirmation token comes from (step 1's response, after approval) and ties consent=true to a two-phase flow rather than a single flag. The consent text itself is duplicated verbatim from the schema, which limits the added value.

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 (submit an enquiry to human providers) and immediately fences off what it is not (not a purchase, not a guaranteed quote). The two-step framing is distinctive enough that an agent can separate it from the checker_* and enquiry_* siblings.

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 per-step conditions: step 1 with answers+consent=true to validate and obtain a token, step 2 only if the person agrees, with the same answers plus the token. The gate ('only if the person agrees') and the downstream email-click requirement are both spelled out.

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