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 reveals the action type but not behavioral consequences: whether the trigger is synchronous, whether the device must be armed, or any side effects on pending measurements. This is thin for a state-changing operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
