Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, and the description adds meaningful behavioral context beyond that: this is a soft delete, the whole listing is discarded, and the slug is freed for reuse. It also repeats and enforces the owner-only constraint. It stops short of describing recoverability or audit effects, but the provided details substantially exceed annotation-only guidance.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
