Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already disclose that the operation is destructive, idempotent, and not read-only. The description adds a meaningful nuance by saying "soft-delete," but it does not explain recoverability, data retention, or required permissions beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
