Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral disclosure burden. 'Jump to a specific frame in the timeline' clearly conveys that this is a non-destructive navigation action affecting the current frame. It does not mention whether playback is stopped or whether the change can be undone, but for such a simple operation the core behavior is transparent enough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
