Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden, and it discloses what the tool returns: field metadata including key, label, type, required status, help text, and allowed options. It also explains how the returned field keys relate to submit_enquiry. It is clearly a read-only metadata operation, though it does not explicitly state side-effect absence or response shape.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
