Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It only states the group is retrieved and returns a Group object, but does not disclose any behavioral traits such as required permissions, error handling (e.g., if group not found), or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
