Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false, and the description's action 'Delete' aligns with these. The note about clearing sensitive data adds a use case but not a new behavioral trait. No contradiction, but the description adds minimal context beyond what annotations already convey.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
