Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of explaining behavior. It discloses what the tool returns (every field's metadata) and implies a read-only, informational operation. The downstream instruction about submit_enquiry makes clear that this tool itself does not submit answers, though it does not explicitly state 'read-only'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
