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

With no annotations, the description carries the full behavioral burden and does so: it discloses validation behavior, that step 1 returns a summary/consent line/token rather than submitting, that the person must approve before submission, and that an email link must be clicked before any provider sees the data. It also spells out the exact consent semantics, which is essential side-effect context.

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 text is long and runs on, but every sentence is load-bearing for a two-step consent-gated workflow, and the critical 'NOT a purchase' constraint is front-loaded. Slightly denser than ideal, but not padded.

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?

Despite having no output schema, the description explains what each call returns (summary, consent line, confirmation token) and the downstream consequences (email with a click-through link before providers see details). For a complex nested-object tool with a two-phase protocol, nothing an agent needs 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 coverage is 100%, so the schema already documents all three parameters, but the description still adds workflow meaning: answers are keyed by field key from enquiry_fields, consent must be true, and confirmation is the step-1 token passed in a second call after approval. That temporal/role guidance goes beyond the schema field text.

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 human providers) and immediately scopes what it is NOT (not a purchase, not a guaranteed quote), which cleanly separates it from the calculate/calculator_describe siblings. An agent can identify the operation without opening the 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?

Gives explicit two-step usage: step 1 call with answers + consent=true to validate and get a token, step 2 only if the person agrees, calling again with the same answers plus the confirmation token. It also names the source of answer keys (enquiry_fields), so the conditions selecting each call are unambiguous.

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