Takes a YouTube URL, extracts the transcript, and you (Claude) summarize it. Outputs Obsidian-ready markdown. Zero friction: share a link, get actionable notes.
This skill's tools live at:
/Users/eddale/Documents/GitHub/powerhouse-lab/skills/youtube-processor/tools/
Step 1: Python extracts the transcript (no API key needed) Step 2: You (Claude) summarize using your intelligence + context Step 3: You write the Obsidian-formatted output
This approach means you can use mission-context, newsletter-coach, and other skills during summarization.
| Environment | Method |
|---|---|
| Claude Code | Local Python script (Step 1a) |
| Claude.ai / Mac Client | API via WebFetch (Step 1b) |
Run the Python tool to get the transcript:
cd /Users/eddale/Documents/GitHub/powerhouse-lab/skills/youtube-processor/tools && \
python3 get_transcript.py --url "[URL]"
For JSON output (easier to parse):
python3 get_transcript.py --url "[URL]" --json
Use the API endpoint via WebFetch:
WebFetch: https://youtube-processor-eight.vercel.app/transcript?url=[VIDEO_URL]
The API returns JSON:
{
"success": true,
"video_id": "abc123",
"language": "en",
"transcript": "...",
"char_count": 5000,
"word_count": 850
}
Example prompt for WebFetch: "Extract the transcript text from the response"
Once you have the transcript, summarize it based on what the user needs:
