Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare this is a non-read-only, non-destructive, open-world mutation, so the safety profile is covered structurally. The description adds only that the target is a revoked member; it says nothing about required admin privileges, whether prior sessions/2FA state are preserved, or what a partial failure looks like.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
