Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish destructiveHint=true and non-idempotency, but the description adds value beyond them: the archive-based mechanism, bounded batch edits, one result per item, and the instruction to report partial failures rather than claiming whole-batch success. The mild internal tension between 'archiving' and 'permanently deletes a root record' is a wording wrinkle, not a contradiction of the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
