Tutorial: Analyzing GitHub Repositories

Learn how to analyze GitHub repositories and generate comprehensive codebase documentation with C3.x analysis.

Time: 20 minutes | Level: Intermediate | Result: Complete codebase skill with patterns, examples, and architecture

What You’ll Learn

  • How to scrape GitHub repositories
  • How to use C3.x codebase analysis (patterns, test extraction, how-to guides)
  • How to combine GitHub + local codebase analysis
  • How to generate ARCHITECTURE.md

Step 1: Basic GitHub Scraping

skill-seekers github \
  --repository facebook/react \
  --output output/react-repo/

Step 2: Add Local Analysis (Unlimited!)

# Clone repo locally first
git clone https://github.com/facebook/react.git /tmp/react

# Analyze with C3.x features
skill-seekers github \
  --repository facebook/react \
  --local-repo-path /tmp/react \
  --output output/react-complete/

What you get:

  • Pattern detection (Singleton, Factory, Observer, etc.)
  • Test example extraction
  • How-to guide generation
  • Configuration analysis
  • Architectural overview (ARCHITECTURE.md)

Step 3: Review Generated Files
