## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

## Documentation

### YouTube Summarizer Skill

Automatically fetch transcripts from YouTube videos, generate structured summaries, and deliver full transcripts to messaging platforms.

### When to Use

Activate this skill when:

User shares a YouTube URL (youtube.com/watch, youtu.be, youtube.com/shorts)
User asks to summarize or transcribe a YouTube video
User requests information about a YouTube video's content

### Dependencies

Required: MCP YouTube Transcript server must be installed at:
/root/clawd/mcp-server-youtube-transcript

If not present, install it:

cd /root/clawd
git clone https://github.com/kimtaeyoon83/mcp-server-youtube-transcript.git
cd mcp-server-youtube-transcript
npm install && npm run build

### 1. Detect YouTube URL

Extract video ID from these patterns:

https://www.youtube.com/watch?v=VIDEO_ID
https://youtu.be/VIDEO_ID
https://www.youtube.com/shorts/VIDEO_ID
Direct video ID: VIDEO_ID (11 characters)

### 2. Fetch Transcript

Run this command to get the transcript:

cd /root/clawd/mcp-server-youtube-transcript && node --input-type=module -e "
import { getSubtitles } from './dist/youtube-fetcher.js';
const result = await getSubtitles({ videoID: 'VIDEO_ID', lang: 'en' });
console.log(JSON.stringify(result, null, 2));
" > /tmp/yt-transcript.json

Replace VIDEO_ID with the extracted ID. Read the output from /tmp/yt-transcript.json.

### 3. Process the Data

Parse the JSON to extract:

result.metadata.title - Video title
result.metadata.author - Channel name
result.metadata.viewCount - Formatted view count
result.metadata.publishDate - Publication date
result.actualLang - Language used
result.lines - Array of transcript segments

Full text: result.lines.map(l => l.text).join(' ')

### 4. Generate Summary

Create a structured summary using this template:

📹 **Video:** [title]
👤 **Channel:** [author] | 👁️ **Views:** [views] | 📅 **Published:** [date]

**🎯 Main Thesis:**
[1-2 sentence core argument/message]

**💡 Key Insights:**
- [insight 1]
- [insight 2]
- [insight 3]
- [insight 4]
- [insight 5]

**📝 Notable Points:**
- [additional point 1]
- [additional point 2]

**🔑 Takeaway:**
[Practical application or conclusion]

Aim for:

Main thesis: 1-2 sentences maximum
Key insights: 3-5 bullets, each 1-2 sentences
Notable points: 2-4 supporting details
Takeaway: Actionable conclusion

### 5. Save Full Transcript

Save the complete transcript to a timestamped file:

/root/clawd/transcripts/YYYY-MM-DD_VIDEO_ID.txt

Include in the file:

Video metadata header
Full transcript text
URL reference

### 6. Platform-Specific Delivery

If channel is Telegram:

message --action send --channel telegram --target CHAT_ID \\
  --filePath /root/clawd/transcripts/YYYY-MM-DD_VIDEO_ID.txt \\
  --caption "📄 YouTube Transcript: [title]"

If channel is other/webchat:
Just reply with the summary (no file attachment).

### 7. Reply with Summary

Send the structured summary as your response to the user.

### Error Handling

If transcript fetch fails:

Check if video has captions enabled
Try with lang: 'en' fallback if requested language unavailable
Inform user that transcript is not available and suggest alternatives:

Manual YouTube transcript feature
Video may not have captions
Try a different video

If MCP server not installed:

Provide installation instructions
Offer to install it automatically if in appropriate context

If video ID extraction fails:

Ask user to provide the full YouTube URL or video ID

### Examples

See examples/ directory for sample outputs.

### Quality Guidelines

Be concise: Summary should be scannable in 30 seconds
Be accurate: Don't add information not in the transcript
Be structured: Use consistent formatting for easy reading
Be contextual: Adjust detail level based on video length

Short videos (<5 min): Brief summary
Long videos (>30 min): More detailed breakdown

### Notes

MCP server uses Android client emulation to bypass YouTube's cloud IP blocking
Works reliably from VPS/cloud environments where yt-dlp often fails
Supports multiple languages with automatic fallback to English
Transcript quality depends on YouTube's auto-generated captions or manual captions
