Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden; it does disclose the critical trait — irreversibility — which is exactly the risk signal an agent needs for a destructive tool. However, it says nothing about required permissions, whether related comments/attachments are cascaded or orphaned, or failure behavior on a nonexistent ID.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
