Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the primary behavioral effect (playing all clips in the row) but omits potential side effects, prerequisites, or behavior when a scene is already playing. With no annotations, the description carries the full burden, and while it conveys the core action, it lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
