Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description's capitalized 'ALL' usefully emphasizes the unbounded scope of the delete, but it says nothing about irreversibility, cascade effects on subscriptions/traffic history, or permissions required.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
