Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds nothing beyond that: it does not say what the log contains, whether it is paginated, how far back it goes, or how it differs from get_notifications. With annotations carrying the bar, this is a bare restatement with no added behavioral context, and it does not contradict the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
