## Features Implemented

### Quality Management Functions

All functions are accessible from the shell namespace:

- **`crack()`** - Runs comprehensive quality checks (lint → typecheck → scan → test)
- **`test()`** - Runs pytest with coverage
- **`lint()`** - Runs ruff check and format check
- **`scan()`** - Runs bandit security scan
- **`format_code()`** - Formats code with ruff
- **`typecheck()`** - Runs mypy type checking
- **`show_adapters()`** - Displays enabled QA adapters in a table
- **`show_hooks()`** - Shows configured pre-commit hooks

### Session Tracking

Full integration with Session-Buddy MCP:

- **Component Name**: `crackerjack`
- **Component Type**: `inspector` (validates other components)
- **Metadata Emitted**:
  - Version (from importlib.metadata)
  - Enabled adapters (pytest, ruff, mypy, bandit)
  - Component type (inspector)
  - Project root path

### Session Lifecycle

1. **Session Start** (async, fire-and-forget):

   ```python
   await session_tracker.emit_session_start(
       shell_type="CrackerjackShell",
       metadata={
           "version": "0.51.0",
           "adapters": ["pytest", "ruff", "mypy", "bandit"],
           "component_type": "inspector",
           "project_root": "/path/to/project",
       }
   )
   ```

1. **Session End** (via atexit hook):

   ```python
   await session_tracker.emit_session_end(
       session_id="session_abc123",
       metadata={}
   )
   ```

### Enhanced Banner

# Start the admin shell
crackerjack shell

# Example session
$ crackerjack shell
Crackerjack> crack()           # Run all quality checks
Crackerjack> test()            # Run test suite
Crackerjack> lint()            # Run linting
Crackerjack> scan()            # Security scan
Crackerjack> show_adapters()   # Show QA adapters
Crackerjack> exit()            # Exit (emits session end)
```

## Testing

### Unit Tests (10 tests, all passing)

```bash
cd /Users/les/Projects/crackerjack
pytest tests/unit/shell/test_adapter.py::TestCrackerjackShell -v
```

**Tests**:

1. `test_initialization` - Shell initialization
1. `test_component_name` - Component name is "crackerjack"
1. `test_component_version` - Version retrieval
1. `test_adapters_info` - Adapter information
1. `test_banner` - Banner generation
1. `test_namespace_helpers` - Helper functions in namespace
1. `test_show_adapters` - Adapters display
1. `test_session_start_emission` - Session start event
1. `test_session_end_emission` - Session end event
1. `test_close` - Shell cleanup

### Integration Tests (2 tests, optional)

```bash
# Run integration tests (requires actual tools)
pytest tests/unit/shell/test_adapter.py::TestCrackerjackShellIntegration -v
```

## Dependencies

### Added

- **`ipython>=8.0.0`** - Interactive Python shell
- **`oneiric>=0.3.2`** (already present) - AdminShell base class

### Required Tools

- **pytest** - Test runner
- **ruff** - Linter and formatter
- **mypy** - Type checker
- **bandit** - Security linter
- **rich** - Terminal formatting

## Architecture

```
oneiric.shell.AdminShell (base class)
    ├── Session tracking (SessionEventEmitter)
    ├── IPython shell management
    └── Banner and namespace management

crackerjack.shell.CrackerjackShell (extends AdminShell)
    ├── Quality management helpers
    ├── Crackerjack-specific metadata
    ├── Rich console integration
    └── Session tracking override
```

## Session Tracking Flow

1. **Shell Start** (`crackerjack shell`)

   - `CrackerjackShell.start()` called
   - IPython shell initialized
   - `_notify_session_start_async()` emits event to Session-Buddy MCP
   - Session ID stored

1. **Shell Usage**

   - User calls quality functions (crack, test, lint, etc.)
   - Functions execute subprocess commands (pytest, ruff, etc.)
   - Rich console displays formatted output

1. **Shell Exit** (Ctrl+D or `exit()`)

   - `atexit` handler triggers `_sync_session_end()`
   - Background thread emits session end event to Session-Buddy MCP
   - Session tracker cleanup

## Integration with Session-Buddy MCP

When Session-Buddy MCP is available (port 8678):

- **Session Start Events** tracked with metadata
- **Session End Events** tracked with duration calculated by Session-Buddy
- **Component Metadata**: version, adapters, project root
- **Session Type**: "CrackerjackShell"

If Session-Buddy is not available:

- Shell still functions normally
- Session tracking gracefully degrades
- Debug logging shows unavailability

## Usage Examples
