Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false and destructiveHint=true, so the description's statement 'Delete' aligns with destructiveHint. It adds minor context about clearing sensitive data but does not disclose additional behavioral traits like idempotency (already hinted as true) or error handling.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
