Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the behavioral burden. It discloses the key state transition (draft → live) and the consequence (attendee registrations become possible), but it does not mention prerequisites such as what happens if the event is already live, permission requirements, or whether the action is reversible via unpublish_event.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
