Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The phrase 'permanently delete' conveys irreversibility, which aligns with and reinforces the destructiveHint=true annotation. However, beyond that, it does not disclose additional behavioral details like cascading effects, idempotency behavior, or permission requirements. Annotations already cover the destructive and idempotent nature, so the description adds minimal new context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
