Download video or audio from supported sites (YouTube, Rumble, etc.).

Watch a video: download it with captions and extract key frames.

Returns a manifest describing a bundle on disk - the caption transcript plus scene-change key frames whose filenames carry their timestamp, so what was on screen can be lined up against what was said. Use this to analyse a tutorial, demo, talk, or screen recording rather than merely archive it.

Check status before trusting the bundle: partial means the captions or the frames are missing, and captions.fallback then names the audio-transcriber skill to recover a transcript.

Write a video-built skill, or append another video's findings to one.

You supply the body - reading the transcript and frames is your job, not this tool's. It owns the mechanics: frontmatter, the provenance table every claim stays traceable to, the version bump, and WORKFLOW.md.

Appending a video the skill already lists is refused rather than duplicated, so re-running a pipeline is safe. Call list_watch_skills first to see which skill a new video belongs to.

Default to append. Use replace when the new source contradicts the skill, changes a conclusion, supersedes rather than extends it, leaves the body no longer reading as one document, or outgrows the description. A create or replace without a "What would change this skill" section is refused.

List video-built skills under a root and the videos each already has.

Use it before building: it says whether a new video extends an existing skill and whether that skill already covers it.

Invoke the download_all operation.

Invoke the download_video operation.

Find a channel's video links; queue them on self.links and return them.

Invoke the open_file operation.

Invoke the progress_hook operation.

Invoke the set_progress_callback operation.

Download a video with its captions and extract scene-change key frames.

Returns the bundle manifest: the media, the transcript, the key frames, and whatever could not be obtained. status is success only when both captions and frames are present, so a caller can surface a partial result before reasoning over an incomplete bundle. A degraded run never raises.
