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/paid, no quote is guaranteed, and it is free. It also enumerates what is returned (recipients, consent wording, confirmation), giving strong non-transactional context, though it does not explicitly state the call is side-effect free.

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 lead directive 'Read first.' is well front-loaded and the passage is short, but the disclaimers ('not a purchase, not a guaranteed quote' vs 'Nothing is bought, ordered or paid; no quote is guaranteed') largely repeat the title, adding length without new information.

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 must explain what the tool returns, and it does: recipients of the details, the consent wording, and the confirmation step. Combined with the non-transactional framing, this is nearly complete for a zero-parameter describe tool.

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 there is nothing for the description to disambiguate and the baseline is 4. The empty schema means no parameter semantics are needed.

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 what the tool returns (a plain explanation of what an enquiry is, plus who receives details, consent wording, and confirmation) and distinguishes it from the write-oriented submit_enquiry. It is clear but the framing ('States plainly what submit_enquiry does') describes the content indirectly rather than naming its own action upfront.

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' is an explicit directive that positions this tool ahead of submit_enquiry in the workflow. It conveys the ordering clearly, though it does not name the sibling alternative or state an explicit when-not-to-use condition.

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