Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true, and the description reinforces permanence ('permanently delete') and the cascading effect ('and its saved entries'). It adds context about authentication requirement, which is not in annotations. No contradictions found.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
