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 only states the basic retrieval function but fails to mention any behavioral traits such as read-only nature, authentication requirements, rate limits, or error handling (e.g., what happens if event_id does not exist).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
