Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. It correctly discloses the instant/no-transition behavior, but says nothing about reversibility, how to restore program output, or whether this affects only the program bus versus preview — gaps for a state-mutating switcher command.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
