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

With no annotations, the description carries the burden of explaining behavior. It states the returned content and the exhaustive scope ('Every field'), but does not explicitly disclose that this is a read-only, side-effect-free lookup or describe the response shape. This is adequate for a simple metadata tool but leaves some traits implicit.

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 short sentences convey the purpose, content, and downstream use with no redundancy. The main information is front-loaded and every clause earns its place.

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 parameterless metadata tool with no output schema and no annotations, the description is nearly sufficient: it tells the agent what fields are returned and how to use them. It lacks only an explicit statement of the response container or a direct relationship to enquiry_describe, but neither is essential for invoking the 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 has zero parameters, so there is no parameter-level documentation burden. The description usefully explains how the returned field keys relate to submit_enquiry, which is the only semantic guidance an agent needs.

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 clearly identifies the resource as 'Every field of the Machinery Transport Quotes enquiry' and enumerates the attributes returned (key, label, type, required, help text, options). It lacks an explicit verb such as 'list' or 'retrieve', and it does not directly contrast itself with enquiry_describe, though the field-specific scope is clear.

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 description gives a clear workflow: obtain fields from this tool, then pass answers to submit_enquiry using the field keys. It does not explicitly state when not to use this tool or how it differs from enquiry_describe, so it falls short of a 5.

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