Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. 'Delete' implies a destructive mutation, but the description doesn't disclose critical behavioral traits like whether deletion is permanent, what permissions are required, what happens to associated resources (memberships, rooms), or error conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
