Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It only states that it returns stories from an RSS feed, without mentioning whether it's read-only, pagination, rate limits, or the exact structure of the response. The description is minimal and does not add context beyond the basic function.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
