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

With no annotations provided, the description carries the burden and discloses important behavioral context: the enquiry is free, nothing is purchased or ordered, and no quote is guaranteed. It also says the tool returns who receives details, the consent wording, and confirmation behavior, though it stops short of explicitly declaring read-only status or auth needs.

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 concise and front-loads the key usage instruction with "Read first." It efficiently covers the main purpose and expectations without unnecessary filler.

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, no-output-schema describe tool with no annotations, the description provides enough context about what information is returned and what the enquiry does not involve. It could be slightly stronger by explicitly stating that it is purely informational/read-only, but it is largely complete for the tool's complexity.

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 semantics to document and the baseline is 4. The description's mentions of returned content are output-related rather than input parameter guidance.

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 that the tool plainly describes what submit_enquiry does and also returns consent-related details. It distinguishes the informational/read-first nature from the actual submission action, though it does not explicitly differentiate itself from other siblings such as 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?

"Read first" gives clear sequencing guidance: call this before submit_enquiry. It also clarifies expectations by stating that nothing is bought, ordered, paid, or guaranteed, but it does not name when not to use the tool or list alternative siblings.

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