Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false and idempotentHint=false, so the safety profile is covered. The description goes meaningfully beyond that by enumerating exactly what is wiped (status, blocks, trust level, metrics, action history) and by explaining that the author is recreated with a clean record on the next moderation — a non-obvious consequence that materially affects the decision to call it.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
