Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish the operation is destructive and idempotent. The description adds no behavioral context beyond this, failing to disclose what happens to dependent entities (e.g., planned courses using this location), whether deletion is permanent, or permission requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
