Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true. The description adds 'Cannot be undone', explicitly stating irreversibility, which is not in the annotations. However, it does not disclose other behavioral aspects like authorization or effects on dependent objects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
