Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and idempotentHint=false, and the description adds substantial context beyond them: stops in-flight machines, frees a cap slot, purges review artifacts permanently while retaining the audit row, re-import restores the row in place, and a replay changes no row. It also discloses owner-scoping and 404 behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
