urjuyaimon09 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
Workflow
- 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.
- 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(' ')
- Generate Summary
Create a structured summary using this template:
📹 Video: [title] 👤 Channel: [author] | 👁️ Views: [views] | 📅 Published: [date]

--caption "📄 YouTube Transcript: [title]"
If channel is other/webchat: Just reply with the summary (no file attachment).

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
