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 explicitly discloses read-only behavior, no new analysis, no rate-limit cost, and the output shape matching roast_idea. This covers key behavioral aspects, though error handling or not-found behavior is not mentioned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
