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 does disclose the behavioral trait of including threaded replies, which is helpful. However, it lacks other behavioral details such as ordering, pagination, or authentication requirements. For a read operation, this is minimal but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
