Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description must disclose behavior. It only says 'Stop a clip slot.' It does not mention whether it resets the clip position, if the slot needs to be playing, what happens if the slot is empty, or any side effects. This is insufficient for safe invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
