Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully disclose behavior. It mentions returning child issues and comments, but omits details such as pagination, sorting, limits, error handling, or whether the result is a flat list or nested. This is insufficient for a retrieval tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
