Build a development environment where Claude 4 and Copilot work together with one command
Real Working Implementation Examples
Copy-and-paste ready code examples and script collections
:material-workflow: Workflow Automation Templates
Complete automation templates using GitHub Actions
Security Implementation Patterns

Prerequisites Check¶
Before practicing this guide, please verify the following:
Required Prerequisites
- Basic Git/GitHub operations
- Node.js/npm usage experience
- Command line basics
- GitHub Actions fundamentals
Section 1: Fully Automated Environment Setup¶
Claude Code CLI Setup¶
Install the latest Claude Code CLI and configure it for Claude 4 models.
#!/bin/bash
# claude-setup.sh - Claude Code CLI Complete Setup Script
set -e
echo "🚀 Starting Claude Code CLI setup..."
# 1. Node.js environment check
if ! command -v node &> /dev/null; then
echo "❌ Node.js not found. Please install Node.js first."
exit 1
fi
# 2. Claude Code CLI installation
echo "📦 Installing Claude Code CLI..."
npm install -g @anthropic-ai/claude-code@latest
# 3. Create configuration directory
mkdir -p ~/.claude/{commands,hooks,templates}
# 4. Project-specific configuration
cat > ./.claude/config.json << 'EOF'

"post-merge": ["claude 'Check dependencies and test status after merge'"]
},
"commands": {
"review": "Review this pull request and point out improvements",
"debug": "Analyze error logs and suggest fixes",
"optimize": "Identify performance bottlenecks and optimize"
}
}
EOF
# 5. Custom command configuration
cat > ~/.claude/commands/security-scan.md << 'EOF'
# Security Scan Command
This command performs:
1. Dependency vulnerability checks
2. Detection of potential code security issues
3. OWASP standard evaluation
4. Fix suggestion generation
Usage: `claude -c security-scan`
