Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations (destructiveHint=true, idempotentHint=true), the description discloses the specific effect (sets deleted_at, hidden from .live scope) and confirms re-deleting is a no-op success. This adds meaningful behavioral context, though it does not mention potential side effects or permissions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
