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 substance: nothing is bought, ordered or paid, no quote is guaranteed, it is free, and it describes who receives the details and the consent wording. It does not clarify whether this descriptor tool itself has any side effects or auth requirements.

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?

Front-loaded with the imperative "Read first" and reasonably compact, but the middle sentences are run-on and spend most of their budget explaining the sibling tool rather than this one.

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 cover the return value, and it does list recipients, consent wording, and confirmation mechanics. Given the trivial empty input schema and read-only nature, this is largely adequate, though it could more clearly separate its own output from submit_enquiry's behavior.

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 there is nothing for the description to disambiguate; baseline for a no-parameter tool is 4.

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?

It signals a read-only descriptor ("Read first") and explains that it documents what submit_enquiry does, plus returns consent/recipient/confirmation details. The framing leans heavily on describing the sibling submit_enquiry rather than this tool itself, which slightly blurs what enquiry_describe returns versus what it explains.

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 an explicit ordering instruction implying it should be consulted before submit_enquiry, and the title clarifies this is not a purchase or guaranteed quote. It stops short of naming alternatives or listing when-not-to-use conditions.

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