## Dev Environment Overview

Core DevOps provides a sandboxed, immutable development environment based on LinuxKit with 100+ embedded tools.

## Quick Start

```bash
# First time setup
core dev install
core dev boot

# Open shell
core dev shell

# Or mount current project and serve
core dev serve
```

## dev install

Download the core-devops image for your platform.

```bash
core dev install [flags]
```

### Flags

| Flag | Description |
|------|-------------|
| `--source` | Image source: `github`, `registry`, `cdn` (default: auto) |
| `--force` | Force re-download even if exists |

### Examples

```bash
# Download image (auto-detects platform)
core dev install

# Force re-download
core dev install --force
```

## dev boot

Start the development environment.

```bash
core dev boot [flags]
```

### Flags

| Flag | Description |
|------|-------------|
| `--memory` | Memory allocation in MB (default: 4096) |
| `--cpus` | Number of CPUs (default: 4) |
| `--name` | Container name (default: core-dev) |

### Examples

```bash
# Start with defaults
core dev boot

# More resources
core dev boot --memory 8192 --cpus 8
```

## dev shell

Open a shell in the running environment.

```bash
core dev shell [flags]
```

### Flags

| Flag | Description |
|------|-------------|
| `--console` | Use serial console instead of SSH |

### Examples

```bash
# SSH into environment
core dev shell

# Serial console (for debugging)
core dev shell --console
```

## dev serve

Mount current directory and start the appropriate dev server.

```bash
core dev serve [flags]
```

### Flags

| Flag | Description |
|------|-------------|
| `--port` | Port to expose (default: 8000) |
| `--path` | Subdirectory to serve |

### Auto-Detection

| Project | Server Command |
|---------|---------------|
| Laravel (`artisan`) | `php artisan octane:start` |
| Node (`package.json` with `dev` script) | `npm run dev` |
| PHP (`composer.json`) | `frankenphp php-server` |
| Other | `python -m http.server` |

### Examples

```bash
# Auto-detect and serve
core dev serve

# Custom port
core dev serve --port 3000
```

## dev test

Run tests inside the environment.

```bash
core dev test [flags] [-- custom command]
```

### Flags

| Flag | Description |
|------|-------------|
| `--unit` | Run only unit tests |

### Test Detection

Core auto-detects the test framework:

1. `.core/test.yaml` - Custom config
2. `composer.json` → `composer test`
3. `package.json` → `npm test`
4. `go.mod` → `go test ./...`
5. `pytest.ini` → `pytest`
6. `Taskfile.yaml` → `task test`

### Examples

```bash
# Auto-detect and run tests
core dev test

# Custom command
core dev test -- go test -v ./pkg/...
```

### Test Configuration

Create `.core/test.yaml` for custom test setup:

```yaml
version: 1

commands:
  - name: unit
    run: vendor/bin/pest --parallel
  - name: types
    run: vendor/bin/phpstan analyse
  - name: lint
    run: vendor/bin/pint --test

env:
  APP_ENV: testing
  DB_CONNECTION: sqlite
```

## dev claude

Start a sandboxed Claude session with your project mounted.

```bash
core dev claude [flags]
```

### Flags

| Flag | Description |
|------|-------------|
| `--no-auth` | Clean session without host credentials |
| `--auth` | Selective auth forwarding (e.g., `gh,anthropic`) |

### What Gets Forwarded

By default, these are forwarded to the sandbox:
- `~/.anthropic/` or `ANTHROPIC_API_KEY`
- `~/.config/gh/` (GitHub CLI auth)
- SSH agent
- Git config (name, email)

### Examples

```bash
# Full auth forwarding (default)
core dev claude

# Clean sandbox
core dev claude --no-auth

# Only GitHub auth
core dev claude --auth=gh
```

### Why Use This?

- **Immutable base** - Reset anytime with `core dev boot --fresh`
- **Safe experimentation** - Claude can install packages, make mistakes
- **Host system untouched** - All changes stay in the sandbox
- **Real credentials** - Can still push code, create PRs
- **Full tooling** - 100+ tools available in the image

## dev status

Show the current state of the development environment.

```bash
core dev status
```

Output includes:
- Running/stopped state
- Resource usage (CPU, memory)
- Exposed ports
- Mounted directories

## dev update

Check for and download newer images.

```bash
core dev update [flags]
```

### Flags

| Flag | Description |
|------|-------------|
| `--force` | Force download even if up to date |
