# Lifecycle Management Guide
Universal lifecycle management for ggen projects using make.toml configuration.
## Overview
The ggen lifecycle system provides a universal project management approach that works across different programming languages and frameworks through declarative make.toml configuration files.
## Core Commands
```bash
# List available phases
ggen lifecycle list
# Run a specific phase
ggen lifecycle run init
ggen lifecycle run build
ggen lifecycle run test
# Run multiple phases in sequence
ggen lifecycle pipeline "init build test deploy"
# Show phase details
ggen lifecycle show build
```
## Production Readiness Integration
```bash
# Check production readiness status
ggen lifecycle readiness
# Update requirement status
ggen lifecycle readiness-update auth-basic complete
# Validate for deployment
ggen lifecycle validate --env production
# Show placeholders that need implementation
ggen lifecycle placeholders --category critical
```
## Available Phases
- **init** - Initialize project structure and dependencies
- **setup** - Set up development environment
- **build** - Build project artifacts
- **test** - Run comprehensive test suite
- **lint** - Code quality checks
- **docs** - Generate documentation
- **deploy** - Deploy to target environment
- **clean** - Clean build artifacts
## Hooks System
Lifecycle phases support before/after hooks for cross-cutting concerns:
```toml
[hooks]
before_all = ["pre-flight-checks"]
after_test = ["coverage-report"]
after_deploy = ["post-deploy-verification"]
```
## Configuration
See `make.toml` files in example projects for complete configuration examples.
