Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the description does not need to restate safety. It adds useful output context ('open or resolved state') but does not disclose other behavioral traits such as pagination, ordering, or whether all conflicts are returned. With annotations carrying the safety profile, this is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
