Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses what content the tool exposes and how the result relates to submit_enquiry, which is valuable context. It does not explicitly state that the operation is read-only or describe the exact response shape, but for a parameterless metadata-listing tool these are minor gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
