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

No annotations are supplied, so 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 triggers an email requiring a click before any provider sees it, and spells out exactly what consent attests to. This 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 critical constraints (not a purchase, not a quote) are front-loaded and the two steps are clearly sequenced. It is dense and slightly repeats the consent wording already present in the schema, which is minor redundancy rather than filler.

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?

With no output schema, the description compensates by describing what each step returns (summary, consent line, token; then submission plus a confirmation email). For a nested-object, two-phase tool, an agent has everything needed to call it 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 structured fields already define the three parameters; the description goes further by explaining that answers are keyed by field key from enquiry_fields and that confirmation is the token returned from step 1 after approval. That sequencing context is genuine added meaning beyond the schema.

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 (submits) and resource (an enquiry to Local SEO for law firm), and immediately bounds scope with 'NOT a purchase, NOT a guaranteed quote.' It also cross-references the sibling enquiry_fields as the source of answer keys, so an agent can place it in the tool family.

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 with answers + consent, step 2 only after the person approves, passing the same answers plus the confirmation token. It also names exclusions (not a purchase, not a quote), leaving nothing to inference.

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