Use when user asks YouTube video extraction, get, fetch, transcripts, subtitles, or captions, or channel browsing. Writes video details and transcription into structured markdown file.

YouTube to Markdown

Multiple videos: Process one video at a time, sequentially. Do not run parallel extractions. Do not create your own scripts.

Step -1: Detect input type

If input is a channel URL (contains /@, /channel/, /c/, /user/) or a bare channel ID (starts with UC, 24 chars), but NOT watch?v=: Read and follow ./subskills/channel_browse.md.

Otherwise: Continue to Step 0.

Step 0: Check if extracted before

python3 ./scripts/20_check_existing.py "<YOUTUBE_URL>" "<output_directory>"

Output JSON contains video_id. Set BASE_NAME = youtube_{video_id} for all subsequent steps.

Write "# Processing {video_id}\n" to <output_directory>/${BASE_NAME}_warmup.tmp. This ensures Write tool is approved before subagents need it.

If exists: false: Continue to Step 1.

If exists: true: Read and follow ./subskills/update_flow.md.

Step 1: Choose output

AskUserQuestion:

  • question: "What do you want to extract from the video?"
  • header: "Output"
  • multiSelect: false
  • options: A. "Summary + Comments (Recommended)" - Summary cross-analyzed with comments. Transcript stored if it should be processed. B. "Summary + Comments + Formatted Transcript" - Option A + cleaned and formatted full transcript → double tokens C. "Summary Only" - Summary of video content D. "Formatted Transcript Only" - Cleaned and formatted full transcript

Step 2: Execute modules

Based on user's choice, read and follow each subskill instruction in ./subskills/{file}. "|" marks possibility to run concurrently.

  • A: transcript_extract.md → (transcript_summarize.md | comment_extract.md) → comment_summarize.md
  • B: transcript_extract.md → (transcript_summarize.md | transcript_polish.md | comment_extract.md) → comment_summarize.md
  • C: transcript_extract.md → transcript_summarize.md
  • D: transcript_extract.md → transcript_polish.md

Step 3: Finalize

python3 ./scripts/50_assemble.py [flag] "${BASE_NAME}" "<output_directory>"

Flags: A=--summary-comments, B=(none), C=--summary-only, D=--transcript-only

Use --debug to keep intermediate files.
