Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, covering the safety profile. The description adds that it returns 'supported count status' and 'separate verified-flow and relevance rankings,' but does not explain pagination, data freshness, or what 'supported count status' means. With annotations in place, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
