Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses substantial behavior beyond the annotations: soft-delete semantics, exact status/visibility transitions, preservation of the row and R2 artifact with a 90-day audit window, idempotency, and the sample-tier rejection. This goes far beyond what destructiveHint and idempotentHint already convey, with no contradiction.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
