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

With no annotations provided, the description carries the full behavioral burden, and it does disclose the return payload shape (key, label, type, required, help text, options) plus how the result feeds submit_enquiry. It does not state read-only semantics, ordering, or any pagination/authorization traits, but for a zero-parameter listing tool the disclosure is solid.

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 with zero filler; the return contents are front-loaded and the integration hint is placed last where it acts as a hand-off. 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?

There is no output schema, so the description must explain the return values and it does so enumeratively. It is nearly complete for a zero-param read tool, missing only ordering/empty-result behavior and a clearer distinction from enquiry_describe.

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 no parameters, so the baseline is 4 per the rubric. The description usefully clarifies the meaning of the field 'key' by noting answers should be keyed by it, which ties the output to the downstream 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 states exactly what is returned: every field of the retail enquiry with key, label, type, required flag, help text and allowed options. It is distinguishable from submit_enquiry by the final sentence, but it never clarifies its relationship to the sibling enquiry_describe, and the head noun phrase ('Every field of...') carries no explicit verb.

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?

Usage is only implied: 'Pass answers to submit_enquiry keyed by field key' signals this is a discovery step preceding submission, which is genuinely useful routing. However, there is no explicit when-to-use and no guidance on choosing this over the sibling enquiry_describe.

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