Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. 'Delete' implies a destructive mutation, but the description never states whether deletion is permanent, whether replies are orphaned or removed, what permissions are required, or how failures behave. The output schema only covers return values, not action-side behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
