Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states 'Get details' without explicitly confirming the read-only nature, auth requirements, error behavior (e.g., if the event is not found), or what constitutes 'details'. This is a minimal but not fully transparent disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
