Video Fetcher to Markdown

Formerly YouTube Fetcher. The skill name stays youtube-fetcher so existing installs keep updating. An independent open-source tool, not affiliated with or endorsed by YouTube, Google, or any other video platform it reads.

Two scripts, one for each kind of source:

Source	Script	How
YouTube with captions	`scripts/fetch_transcript.py`	Reads YouTube's captions. Fast, downloads nothing, no API key.
Instagram, TikTok, X, Vimeo, Facebook and other sites; YouTube without captions; a local video or audio file	`scripts/fetch_media.py`	Downloads with `yt-dlp`, transcribes locally with Whisper, adds a contact sheet of frames.

Both export archival Markdown, plain text, JSON, SRT, or WebVTT and share the same output rules below. Optional yt-dlp adds creator descriptions, chapters, upload dates, and duration to YouTube notes.

Choose the result the user asked for

Bare link, archive, or save: create a Markdown note. Use the user's named directory or exact file when supplied, then report the absolute saved path.
Summary, question, or analysis: retrieve captions with --stdout --timestamps, read the result, and answer the request with timestamp links where useful. Saving an extra note is optional unless requested.
Transcript or subtitle export: choose the requested format. --format txt means plain text; text is the legacy name for Markdown.
Several explicit links: run once per video and report each outcome. A watch URL containing a playlist still means one video; do not expand a playlist.

Resolve scripts/fetch_transcript.py relative to this SKILL.md, using a Python interpreter with the dependencies installed. Do not assume a home-directory, agent, operating system, working directory, or skill-manager path. Quote URLs and paths; put options before -- so IDs beginning with - are accepted.

# SKILL_DIR is the directory containing this SKILL.md
python3 "$SKILL_DIR/scripts/fetch_transcript.py" -- "https://youtu.be/VIDEO_ID"

# Evidence for a summary or answer, with links to the relevant moments
python3 "$SKILL_DIR/scripts/fetch_transcript.py" --stdout --timestamps -- URL
