Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and idempotentHint=true. The description aligns with these by stating 'Delete' and adds context about clearing sensitive data, without contradicting the annotations. It does not reveal additional behavioral details beyond annotations, but the simple nature of the tool makes this adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
