🚀 Quick Start

1. Create Your Repository

Click "Use this template" button above, then:

# Clone your new repository
git clone https://github.com/YOUR_USERNAME/YOUR_PLUGIN.git
cd YOUR_PLUGIN

# Run setup script
./scripts/setup.sh

The setup script will:

• Replace {{PLUGIN_NAME}} placeholders with your plugin name
• Configure git hooks
• Install validation dependencies
• Create your first plugin structure

2. Customize Your Plugin

# Edit plugin metadata
nano .claude-plugin/plugin.json

# Create your first skill
mkdir -p skills/your-skill-name
nano skills/your-skill-name/skill.md

# Validate your changes
./scripts/validate-all.sh

3. Develop and Test

# Run validation
./scripts/validate-all.sh

# Run tests (if you have tests)
# ./tests/test-all.sh

# Install locally to test
/plugin marketplace add /path/to/your-plugin
/plugin install {{PLUGIN_NAME}}@{{PLUGIN_NAME}}-marketplace

4. Push and Deploy

git add .
git commit -m "feat: Initial plugin implementation"
git push

# GitHub Actions will automatically:
# - Validate your plugin
# - Run ShellCheck
# - Check security
# - Run tests

🔧 Development Workflow

Daily Development

# 1. Make changes
nano skills/my-skill/skill.md

# 2. Validate locally (pre-commit hook does this automatically)
./scripts/validate-all.sh

# 3. Test
./tests/test-all.sh

# 4. Commit (hook validates automatically)
git add .
git commit -m "feat: Add new skill"

# 5. Push (GitHub Actions validates automatically)
git push

Creating a New Skill

# Use the provided script
./scripts/create-skill.sh my-new-skill

# Or manually:
mkdir -p skills/my-new-skill
cat > skills/my-new-skill/skill.md << 'EOF'
