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 adds the meaningful '(admin)' permission requirement, but says nothing about irreversibility, cascade effects, or whether the confirm flag is mandatory for this single (non-bulk) operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
