Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the behavioral disclosure. It does so by stating that it shows 'id, request and current phase', giving the agent an understanding of what the tool returns. It also implicitly signals a read-only operation ('Lists'). While it doesn't mention ordering or limits, the behavior is sufficiently disclosed for a zero-parameter listing tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
