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 behavior: nothing is bought, ordered or paid, no quote is guaranteed, it is free, and it returns recipient/consent/confirmation details. For a read-only descriptive tool this is solid disclosure, though it could note that calling it has no side effects on the enquiry itself.

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?

It opens with the useful 'Read first.' lead, but the second sentence is dense and meanders through disclaimers ('Nothing is bought, ordered or paid; no quote is guaranteed; it is free') that partially restate the title. The framing as 'what submit_enquiry does' adds words without adding information about this tool.

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?

For a zero-parameter tool with no annotations and no output schema, the description is reasonably complete: it describes what content comes back (recipients, consent wording, confirmation process) and the key behavioral facts. A little more on the exact shape of the returned text would close the remaining gap.

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. No parameter-level ambiguity exists and the description correctly implies a parameterless informational call.

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 does convey that this tool returns human-readable explanation content (recipients, consent wording, confirmation steps), but it frames the purpose as 'what submit_enquiry does' rather than what this tool itself does, which blurs the line between this describe tool and its sibling. The distinction from enquiry_fields is never made.

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 an explicit ordering cue that this should be consulted before the other enquiry tools, which is real usage guidance. However, there is no when-not condition and no differentiation from the sibling enquiry_fields, only a passing reference to submit_enquiry.

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