Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so no safety contradiction exists. The description adds a 'public' scoping boundary, which helps set expectations about the search universe, but it does not disclose behavior like result ordering, pagination, or coverage limits beyond what annotations and schema show. It contributes only modest additional behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
