Quick Start

When user sends a YouTube URL:

1. Spawn sub-agent with the full pipeline task immediately
2. Reply: "🎬 TubeScribe is processing — I'll let you know when it's ready!"
3. Continue conversation (don't wait!)
4. Sub-agent notification will announce completion with title and details

DO NOT BLOCK — spawn and move on instantly.

First-Time Setup

Run setup to check dependencies and configure defaults:

python skills/tubescribe/scripts/setup.py

This checks: summarize CLI, pandoc/python-docx, ffmpeg, Kokoro TTS

Full Workflow (Single Sub-Agent)

Spawn ONE sub-agent that does the entire pipeline:

sessions_spawn(
    task=f"""
## TubeScribe: Process {youtube_url}

Run the COMPLETE pipeline — do not stop until all steps are done.

### Step 1: Extract
```bash
python3 /Users/matusvojtek/.openclaw/workspace/skills/tubescribe/scripts/tubescribe.py "{youtube_url}"

Note the video_id from the output (e.g., "Source: /tmp/tubescribe_ABC123_source.json" → video_id is ABC123).

Step 2: Read source JSON

Read /tmp/tubescribe_<video_id>_source.json and note:

• metadata.title (for filename)
• metadata.video_id
• metadata.channel, upload_date, duration_string

Step 3: Create formatted markdown

Write to /tmp/tubescribe_<video_id>_output.md:

1. # **<title>**

2. Video info block (Channel, Date, Duration, clickable URL)

3. ## **Participants** — table with bold headers:

   | **Name** | **Role** | **Description** |
   |----------|----------|-----------------|
   

4. ## **Summary** — 3-5 paragraphs

5. ## **Key Quotes** — 5 best with clickable YouTube timestamps

6. ## **Viewer Sentiment** (if comments exist)

7. ## **Best Comments** (if comments exist) — Top 5, NO lines between them:

   Comment text here.
   
   <p align="right">▲ 123 @AuthorName</p>
   
   Next comment text here.
   
   <p align="right">▲ 45 @AnotherAuthor</p>
   

   Just blank line between comments, NO --- separators.

8. ## **Full Transcript** — merge segments, speaker labels, clickable timestamps

Step 4: Create DOCX

Clean the title for filename (remove special chars), then:

pandoc /tmp/tubescribe_<video_id>_output.md -o ~/Documents/TubeScribe/<safe_title>.docx

Step 5: Generate audio

cd ~/.openclaw/tools/kokoro && source .venv/bin/activate

Then Python: read Summary from markdown, generate with Kokoro (voice=0.6af_heart+0.4af_sky), save as MP3 to ~/Documents/TubeScribe/_summary.mp3

Step 6: Cleanup

python3 /Users/matusvojtek/.openclaw/workspace/skills/tubescribe/scripts/tubescribe.py --cleanup <video_id>

Step 7: Open folder

open ~/Documents/TubeScribe/

Report

Tell what was created: DOCX name, MP3 name + duration, video stats. """, label="tubescribe", runTimeoutSeconds=900, cleanup="delete" )

**After spawning, reply immediately:**
> 🎬 Processing "[video title if known, or just the URL]" — I'll let you know when it's ready!

Then continue the conversation. The sub-agent notification announces completion.

Output Structure

~/Documents/TubeScribe/
├── {Video Title}.html         # Formatted document (or .docx / .md)
└── {Video Title}_summary.mp3  # Audio summary (or .wav)

After generation, opens the folder (not individual files) so you can access everything.

Dependencies

Required:

• summarize CLI — brew install steipete/tap/summarize
• Python 3.8+

Optional (better quality):

• pandoc — DOCX output: brew install pandoc
• ffmpeg — MP3 audio: brew install ffmpeg
• yt-dlp — YouTube comments: brew install yt-dlp
• Kokoro TTS — High-quality voices: see https://github.com/hexgrad/kokoro

yt-dlp Search Paths

TubeScribe checks these locations (in order):

If not found, setup downloads a standalone binary to the tools directory. The tools directory version doesn't conflict with system installations.

Queue Handling

When user sends multiple YouTube URLs while one is processing:

Check Before Starting

python skills/tubescribe/scripts/tubescribe.py --queue-status

If Already Processing

# Add to queue instead of starting parallel processing
python skills/tubescribe/scripts/tubescribe.py --queue-add "NEW_URL"
# → Replies: "📋 Added to queue (position 2)"

After Completion

# Check if more in queue
python skills/tubescribe/scripts/tubescribe.py --queue-next
# → Automatically pops and processes next URL

Queue Commands

Batch Processing (multiple URLs at once)

python skills/tubescribe/scripts/tubescribe.py url1 url2 url3

Processes all URLs sequentially with a summary at the end.

Error Handling

The script detects and reports these errors with clear messages:

When an error occurs, report it to the user and don't proceed with that video.

Tips

• For long videos (>30 min), increase sub-agent timeout to 900s
• Speaker detection works best with clear interview/podcast formats
• Single-speaker videos (tutorials, lectures) skip speaker labels automatically
• Timestamps link directly to YouTube at that moment
• Use batch mode for multiple videos: tubescribe url1 url2 url3
