Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already flag destructiveHint=true, yet the description adds genuinely new context: the deletion is permanent, probe history is destroyed alongside the registration, admin request logs are retained for up to 30 days, and an omitted confirm performs no action. That is exactly the destructive/irreversibility detail the annotations cannot convey.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
