Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark this as destructive and not read-only; the description adds the key detail that deletion is 'permanent', signaling irreversibility. This goes beyond the annotations and sets correct expectations, though it does not mention cascading effects or required permissions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
