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

With no annotations, the description carries the full burden and does well: it clarifies the tool is informational, that nothing is bought or paid, that no quote is guaranteed, and that it is free. It also discloses return content: who receives details, consent wording, and how confirmation happens.

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 description is tight and front-loaded with the imperative 'Read first.' Every sentence adds distinct value: the subject scope, the non-transactional nature, and the return contents. No filler or redundant restatement.

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 describing tool with no output schema, the description fully covers what it does, what it does not do, and what it returns. An agent has enough information to invoke it correctly and interpret its result.

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 has zero parameters, so the baseline for this dimension is 4. There are no parameter semantics to document, and the empty schema is consistent with a purely descriptive, no-input tool.

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 clear verb ('states plainly') and resource ('what submit_enquiry does on Gearbox Repair Quotes'), and the title reinforces the non-purchase nature. It differentiates from the sibling submit_enquiry, but does not explicitly distinguish itself from enquiry_fields.

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?

The opening 'Read first' gives clear context that this tool should be consulted before submit_enquiry. It does not explicitly discuss when to prefer it over enquiry_fields or when not to use it, so it stops short of full alternative routing.

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