## 🛠️ Development

### Using KCL Schemas

```kcl
# Import main package
import provisioning.main as prov

# Define infrastructure
server: prov.ServerConfig = {
    name = "web-01"
    plan = "1xCPU-2GB"
    zone = "de-fra1"
    operating_system = "ubuntu-22.04"
}

# Define workflow
workflow: prov.BatchWorkflow = {
    name = "deploy_servers"
    operations = [
        {
            type = "server_create"
            servers = [server]
        }
    ]
}
```

### Validation

All configurations are validated at:
1. **Schema Level** - Type checking and constraint validation
2. **Semantic Level** - Cross-schema relationship validation
3. **Execution Level** - Runtime validation before execution
