🛠️ Automation Scripts

Core Scripts:

• scripts/setup_monitoring.sh: Setup performance monitoring infrastructure
• scripts/apply_tdd_workspace.sh: Apply TDD to all workspace packages
• monitoring/start_monitoring.sh: Start performance monitoring service
• monitoring/stop_monitoring.sh: Stop monitoring service
• monitoring/health_check.sh: Check monitoring system health

Usage Examples:

# Setup complete monitoring infrastructure
./scripts/setup_monitoring.sh

# Apply TDD to all packages
./scripts/apply_tdd_workspace.sh
