Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, non-destructive, and open-world behavior, so the safety profile is covered. The description adds that results are 'dated' and include 'published AI analyst takes', which is useful context, but it does not say anything about freshness, provenance, pagination, or completeness of the research set.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
