Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility for behavioral disclosure. While 'Delete' clearly implies a destructive mutation, it does not state whether the operation is permanent, whether confirmation or special permissions are required, or what side effects occur (e.g., removal from attendee calendars). The description is too thin to adequately characterize the risk.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
