+# YouTube Transcript Analysis
+
+Extract, clean, and analyze YouTube video transcripts to understand content without watching.
+
+## Overview
+
+This skill enables rapid analysis of YouTube videos by extracting transcripts and providing comprehensive summaries. Perfect for research, content review, or understanding video material without time investment.
+
+## Quick Workflow
+
+1. **Extract**: Use `scripts/extract_transcript.sh` to get clean text from YouTube URL
+2. **Read**: Load the extracted transcript file 
+3. **Analyze**: Provide structured summary based on content type
+4. **Format**: Present findings in scannable, organized format
+
+## Extraction Process
+
+Use the bundled script for any YouTube video:
+
+```bash
+scripts/extract_transcript.sh "https://www.youtube.com/watch?v=VIDEO_ID" output.txt
+```
+
+The script automatically:
+- Downloads yt-dlp if not present
+- Extracts captions (auto-generated or manual)
+- Cleans VTT formatting to plain text
+- Provides character count and preview
+
+## Analysis Approach
+
+### Content Type Recognition
+
+Identify video type first, then tailor analysis:
+
+**Educational/Tutorial**: Step-by-step breakdown, key concepts, prerequisites
+**Product Review**: Comparisons, pros/cons, recommendations, specifications  
+**News/Commentary**: Main topics, key arguments, sources cited
+**Entertainment**: Highlights, key moments, recurring themes
+
+### Structure Your Analysis
+
+**For any video type:**
+- **Title/Topic**: Clear description of video content
+- **Duration insight**: Brief/detailed based on transcript length
+- **Key points**: 3-7 main takeaways in bullet format
+- **Notable quotes**: Important statements (if applicable)
+- **Action items**: Next steps or recommendations (if present)
+
+**For technical content:**
+- Include specific terminology, version numbers, tools mentioned
+- Note any code examples or configurations discussed
+- Identify prerequisites or dependencies
+
+### Quality Considerations
+
+**Auto-generated transcripts may have:**
+- Repetitive phrases
+- Transcription errors for technical terms
+- Missing punctuation
+- Filler words ("um", "uh", "you know")
+
+Filter and interpret accordingly - focus on clear, coherent content.
+
+## Advanced Analysis
+
+For detailed analysis patterns and content-specific approaches, see [analysis-patterns.md](references/analysis-patterns.md).
+
+## Error Handling
+
+**If extraction fails:**
+- Video may lack captions
+- May be private/restricted  
+- Network connectivity issues
+- Age-restricted content
+
+**Fallback approach:** Use web_fetch on the YouTube URL to get basic video information, then inform user about transcript limitations.

+
+### Educational Content
+- **Extract**: Core concepts, steps in processes, key facts
+- **Format**: Bullet points for easy scanning
+- **Highlight**: Definitions, formulas, examples
+
+### Product Reviews/Comparisons

+- **Structure**: Step-by-step instructions
+- **Include**: Prerequisites, tools needed, common mistakes
+- **Format**: Numbered steps with key details
+
+## Text Cleaning Notes
+
+### Common Transcript Issues
+- **Repetition**: Auto-generated transcripts often repeat phrases

+- **Filler words**: "uh", "um", "you know" are common
+- **Missing punctuation**: Transcripts lack proper sentence structure
+
+### Quality Indicators
+- **Good quality**: Clear sentences, proper nouns correctly transcribed
+- **Medium quality**: Some repetition, occasional word errors
+- **Poor quality**: Heavy repetition, many transcription errors, missing words
+
+## Analysis Tips
+
+### For Technical Content
+- Look for specific terminology, model names, version numbers
+- Note any code examples or configuration details
+- Identify prerequisites and dependencies mentioned
+
+### For Opinion/Commentary
+- Distinguish between facts and opinions
+- Note sources cited or referenced
