YouTube Summary

Overview

Create structured, educational summaries of YouTube videos following a comprehensive analysis format. This skill combines video metadata and transcript extraction to generate learning-focused summaries with key topics, insights, numerical analysis, and exploratory questions designed for educational use.

When to Use This Skill

Use this skill when:

• User requests a summary or analysis of a YouTube video
• User wants to understand the main points of a video without watching
• User needs educational content breakdown for learning purposes
• User asks for key insights, data points, or critical analysis of video content
• User wants a structured breakdown with timestamps and direct links

Summary Workflow

Step 1: Gather Video Information

First, use the youtube-video-info skill to fetch video metadata:

python /Users/dante/.claude/skills/youtube-video-info/scripts/get_youtube_info.py "<youtube_url>"

Extract:

• video_id - For generating timestamp links
• title - Video title
• duration - Total playback time

Step 2: Extract Video Transcript

Next, use the youtube-transcript skill to get the full transcript:

python /Users/dante/.claude/skills/youtube-transcript/scripts/get_youtube_transcript.py "<youtube_url>"

Extract:

• transcript - Full transcript with timestamps
• formatted_transcript - Human-readable version

Step 3: Analyze and Summarize

Follow the summary guidelines from references/summary_guide.md to create a comprehensive educational summary.

Key Analysis Components:

1. 핵심 주제 (Core Topics)

   • Identify the main themes and ideas
   • Summarize the central message

2. 핵심 내용 (Key Content)

   • Extract important claims, concepts, examples, and cases
   • Highlight significant arguments and supporting evidence

3. 논리 전개 (Logical Flow)

   • Trace how the video reaches its conclusions
   • Identify reasoning patterns and evidence used

4. 맥락 연결 (Context Connection)

   • Link to related background, citations, or conceptual extensions
   • Connect to broader themes or disciplines

5. 데이터 기반 인사이트 (Data-Based Insights)

   • Extract numerical data, statistics, percentages, years mentioned
   • Interpret what these numbers signify
   • Example: "60% of users → indicates a trend inflection point"

6. 탐구형 질문 (Exploratory Questions) Generate 3 types of questions:

   • Questions that encourage critical thinking about core claims
   • Questions that extend the topic to other contexts or fields
   • Questions that explore practical applications or limitations

Step 4: Format Output

Structure the summary according to the template in references/summary_guide.md:

1. 제목: {title}

2. 전체 재생시간: {total_playback_time}

3. 전체요약

4. 구간별 요약
 - 구간1: {interval_title} (⏱️{time_interval})

Formatting Guidelines

Time Formatting:

• Total playback time: [mm:ss] format
• Time intervals: [mm:ss–mm:ss] format
• Timestamp links: &t={seconds}s format (e.g., &t=11s)

Direct Links: Generate clickable links to specific video timestamps:

https://www.youtube.com/watch?v={video_id}&t={timestamp_in_seconds}s

Use transcript timestamps to calculate exact second values for each section.

Content Guidelines

DO:

• Interpret and restructure content from the transcript
• Extract and explain numerical data with context
• Generate insightful critical questions
• Connect concepts to broader themes
• Maintain educational focus

DON'T:

• Copy transcript text verbatim - always interpret and summarize
• Add information not present in the video
• Process unethical or copyright-restricted content
• Use generic summaries - provide specific, substantive analysis
