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 does not say whether this is a read-only operation, whether access requires calendar permissions, or what happens for missing/invalid ids — gaps that matter for a fetch tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
