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

With no annotations, the description carries the full burden and does disclose meaningful traits: nothing is bought, ordered or paid, no quote is guaranteed, and it is free. It also states the tool returns consent wording and confirmation mechanics, which sets expectations. It does not explicitly label itself read-only or describe response format, so it is strong but not exhaustive.

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?

Two sentences, front-loaded with the imperative "Read first," and every clause adds substantive content (scope, cost/reassurance, return contents). It is somewhat dense but free of 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?

No output schema exists, so the description must explain returns, and it does — recipients of details, consent wording, and confirmation method. No parameters need documenting. Complete enough for an agent to call it correctly, though it could state the return format more concretely.

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?

The tool takes zero parameters, so per the rubric the baseline is 4. There is no parameter surface for the description to clarify or omit.

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 function: it explains what submit_enquiry does — starting an enquiry with human providers — and enumerates what it returns (recipient, consent wording, confirmation method). It clearly distinguishes itself from its sibling submit_enquiry by being the read-first explainer rather than the action. It is slightly meta (describing another tool's behavior), which keeps it from a top score.

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?

"Read first" gives explicit ordering guidance before invoking submit_enquiry, and the reference to submit_enquiry names the related alternative. It stops short of an explicit when-not-to-use clause or a direct routing sentence (e.g., 'call submit_enquiry to actually submit'), leaving that to inference.

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