Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds that the search is based on public sources, which is useful context, but it does not disclose other behavioral details such as result ordering, filtering behavior, pagination, or any limitations. It is consistent with the annotations, so no contradiction exists.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
