Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It describes the return format (Markdown with title, metadata, description, content) but does not disclose edge cases like behavior when event is not found, case sensitivity, or read-only nature. Lacks error handling details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
