Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false. The description adds 'permanently', emphasizing irreversibility, which is useful beyond the generic destructive hint. However, it doesn't mention potential side effects on related data, but the low complexity and existing annotations make this acceptable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
