Quick Start

1. Install the Plugin

Option A: Install from Marketplace (Recommended)

# Add the marketplace
/plugin marketplace add Jsnnmsc/claude-code-learning-marketplace

# Install the plugin
/plugin install codebase-learning@Jsnn-marketplace

Option B: Install from GitHub

# Clone the repository
git clone https://github.com/Jsnnmsc/claude-code-learning-marketplace.git

# Install via Claude Code
cd claude-code-learning-marketplace
claude-code plugin install .

Verify installation:

# In Claude Code
/plugin list
# Should show "codebase-learning"

2. First Learning Session

Start with the interactive learning command:

/learn

Claude will ask you:

1. What to learn? Choose "Architecture & Design Patterns"
2. Scope? Choose "Entire codebase overview"
3. Output format? Choose "Interactive Documentation"

The Architecture Analyzer agent will analyze your codebase and provide a comprehensive overview!

3. View Results

The analysis will be automatically saved to a markdown file in .codebase-analysis/ directory. You can open this file in your editor for better viewing with:

• Formatted markdown
• Rendered diagrams
• Clickable file references
• Easy navigation

4. Explore Different Aspects

# Trace how a feature works
/learn-flow authentication

# Discover design patterns
