Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden. It discloses that this is a metadata/field-listing operation, describes the shape of the returned data, and clarifies that actual submission happens through submit_enquiry. The absence of mutation language makes this a clearly passive lookup, though it doesn't explicitly state read-only or permission requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
