Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the behavioral disclosure burden. It does convey that this is a metadata/field-listing operation and that its keys feed into submit_enquiry, implying a read-only, non-mutating behavior. However, it does not explicitly state that it performs no submission, makes no changes, or describe how the field data is returned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
