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

With no annotations, the description carries the burden and does so well: it discloses that nothing is bought, ordered or paid, that no quote is guaranteed, that it is free, and what supplementary content is returned (recipient details, consent wording, confirmation flow). It stops short of confirming the tool itself has no side effects or noting any auth requirements.

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 then a compact enumeration of what the tool discloses. Efficient, though the second sentence packs several ideas together and could be marginally tighter.

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 is the only source of return-value information, and it enumerates the key returns (who receives the details, consent wording, confirmation flow). For a zero-parameter read tool this is nearly complete, missing only explicit confirmation that it is side-effect-free.

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?

Zero parameters, so the baseline is 4; there is nothing for the description to disambiguate. The description appropriately focuses on output content rather than inventing parameter semantics.

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 role: it explains what submit_enquiry does (starts an enquiry with human providers who quote directly) and returns consent/recipient details, which clearly distinguishes it from the sibling submit_enquiry (action) and the dataset_* tools (data access). The phrasing is slightly meta ('states plainly what X does') rather than a direct verb+resource for the tool itself, which keeps it from a 5.

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 a front-loaded directive that implies calling this before submit_enquiry, but it never names submit_enquiry explicitly as the alternative or states when this tool would be inappropriate. The ordering intent is implied rather than spelled out.

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