Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool retrieves active sessions but doesn't describe what constitutes an 'active session', whether the data is real-time or cached, any rate limits, authentication requirements, or error handling. This is inadequate for a tool that likely involves sensitive session data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
