Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the destructive and irreversible nature via 'permanently purges', which is critical behavioral information. However, with no annotations available, it should have covered additional traits like error handling, side effects, or required authentication, but it does not.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
