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 behavioral context: nothing is bought/ordered/paid, no quote is guaranteed, it is free, and it returns who receives the details plus the consent wording. It does not, however, describe response format (e.g., structured vs prose) or note that the tool itself 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 'Read first' instruction is front-loaded and the remaining content is packed into one dense but information-carrying sentence. Wording is slightly self-referential ('States plainly what submit_enquiry does'), which costs a little clarity but not much length.

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?

Because there is no output schema, the description must explain return content, and it does ('who receives the details, the consent wording, and how the person confirms'). Combined with the disclaimers about cost and guarantee, an agent has enough to know what this tool yields, though the exact return shape remains unspecified.

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 the schema baseline is 4. There is nothing parametric for the description to add 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 title and description make clear this is an informational/read tool that explains what submit_enquiry yields ('starts an enquiry with human providers who quote directly'), distinguishing it from submit_enquiry itself. However, the description frames its purpose largely in terms of a sibling tool rather than stating directly 'this returns a description of the enquiry process,' leaving the tool's own identity slightly indirect.

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 a usable ordering hint, implying it precedes submit_enquiry. Beyond that ordering cue, there is no explicit statement of when to call it versus enquiry_fields or submit_enquiry, and no exclusions — usage is only implied.

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