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 implies a read-only lookup but discloses nothing about permissions, whether only upcoming meetings are returned, ordering, or pagination; it also fails to say what happens for an unknown employee_id.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
