Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions 'live feed' and 'Free,' which give some context, but it does not disclose limitations, data freshness, rate limits, or whether the operation is read-only. The behavioral traits are only minimally addressed, and no safety or side-effect information is provided.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
