Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full behavioral burden. It says 'Delete' but never states whether the removal is permanent, whether undo can reverse it, what permissions are needed, or what happens to the surrounding timeline — all critical for a destructive mutation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
