## Implementation Details

### OneiricShell Class

**Location**: `oneiric/shell/adapter.py`

**Key Features**:
- Extends `AdminShell` base class
- Component name: "oneiric"
- Component type: "foundation"
- No orchestration adapters (provides to others)

**Methods**:

```python
class OneiricShell(AdminShell):
    def __init__(self, app: OneiricSettings, config: ShellConfig | None = None)
    def _add_oneiric_namespace(self) -> None
    def _get_component_name(self) -> str | None
    def _get_component_version(self) -> str
    def _get_adapters_info(self) -> list[str]
    def _get_banner(self) -> str
    async def _reload_settings(self) -> None
    async def _show_config_layers(self) -> None
    async def _validate_config(self) -> None
    async def _emit_session_start(self) -> None
    async def _emit_session_end(self) -> None
    async def close(self) -> None
```

### Namespace Helpers

**Available in Shell**:

1. `reload_settings()` - Reload configuration from all layers
2. `show_layers()` - Display config layer precedence table
3. `validate_config()` - Validate current Pydantic model
4. `config` - Current OneiricSettings instance
5. `OneiricSettings` - Configuration class

### CLI Command

**Command**: `oneiric shell`

**Implementation**:
```python
@app.command("shell")
def shell_command() -> None:
    """Start the interactive admin shell for configuration and lifecycle management."""

    async def _shell():
        from oneiric.shell import OneiricShell
        config = load_settings()
        shell = OneiricShell(config)
        shell.start()

    asyncio.run(_shell())
```

### Session Tracking

**Event Emission**:

1. **Session Start**: Automatically emitted when shell starts
   - Component: "oneiric"
   - Shell type: "OneiricShell"
   - Metadata: version, adapters (empty), component_type (foundation)

2. **Session End**: Automatically emitted via atexit hook
   - References session_id from start event
   - Fire-and-forget (background thread)

**Integration**:
- Uses `SessionEventEmitter` from `oneiric.shell.session_tracker`
- MCP transport via stdio to Session-Buddy
- Circuit breaker for resilience
- Graceful degradation if Session-Buddy unavailable

### Banner

```
Oneiric Admin Shell v0.5.1
============================================================
Universal Component Resolution & Lifecycle Management

Session Tracking: Enabled
  Shell sessions tracked via Session-Buddy MCP
  Metadata: version, config layers, lifecycle state

Oneiric is the foundation component providing:
  - Layered configuration (defaults → yaml → local → env)
  - Component lifecycle management
  - Universal adapter system
  - Resolution and activation APIs

Convenience Functions:
  reload_settings()   - Reload configuration from all layers
  show_layers()       - Display config layer precedence
  validate_config()   - Validate current configuration

Available Objects:
  config              - Current OneiricSettings instance
  OneiricSettings     - Configuration class

Type 'help()' for Python help or %help_shell for shell commands
============================================================
```

## Architecture Pattern

### Inheritance Hierarchy

```
AdminShell (oneiric/shell/core.py)
├── Session tracking infrastructure
├── IPython integration
├── Base namespace (app, asyncio, logger, Rich)
└── Virtual methods for component customization
    ↓
OneiricShell (oneiric/shell/adapter.py)
├── Oneiric-specific namespace
├── Component metadata
├── Configuration helpers
└── Session event emission
```

### Session Tracking Flow

```
1. User runs: oneiric shell
   ↓
2. OneiricShell.__init__()
   ↓
3. shell.start() → IPython embed
   ↓
4. _notify_session_start_async()
   ↓
5. SessionEventEmitter.emit_session_start()
   ↓
6. Session-Buddy MCP: track_session_start tool
   ↓
7. Session ID returned and stored
   ↓
8. User interacts with shell
   ↓
9. Shell exits (atexit hook triggered)
   ↓
10. _sync_session_end() → _emit_session_end()
   ↓
11. SessionEventEmitter.emit_session_end()
   ↓
12. Session-Buddy MCP: track_session_end tool
```

## Comparison with Mahavishnu Shell

| Feature | Mahavishnu | Oneiric |
|---------|-----------|---------|
| **Purpose** | Workflow orchestration | Configuration management |
| **Component Type** | orchestrator | foundation |
| **Adapters** | LlamaIndex, Prefect, Agno | None (provides to others) |
| **Helpers** | ps(), top(), errors(), sync() | reload_settings(), show_layers(), validate_config() |
| **Magic Commands** | %repos, %workflow | Base magics only |
| **Namespace** | WorkflowStatus, MahavishnuApp | OneiricSettings, config |
| **CLI Command** | mahavishnu shell | oneiric shell |

## Key Design Decisions

### 1. Relative Imports

Used relative imports in `adapter.py` to avoid circular dependency:

```python
# CORRECT
from .core import AdminShell
from .config import ShellConfig
from .session_tracker import SessionEventEmitter

# WRONG (causes circular import)
from oneiric.shell import AdminShell, ShellConfig
```

### 2. Component Type: Foundation

Oneiric returns empty list for `_get_adapters_info()` because it's the foundation component that provides configuration and lifecycle management to all other components, rather than being an orchestrator itself.

### 3. Async Helpers

Namespace helpers are lambda wrappers around async functions:

```python
"reload_settings": lambda: asyncio.run(self._reload_settings()),
```

This allows synchronous invocation from IPython while maintaining async implementation.

### 4. Fire-and-Forget Session End

Session end emission runs in background daemon thread via atexit hook to avoid blocking shell exit:

```python
def _sync_session_end(self) -> None:
    def emit_in_thread():
        # Run in background thread
        thread = threading.Thread(target=emit_in_thread, daemon=True)
        thread.start()
        # Don't join - fire and forget
```

## Usage Examples

### Basic Usage

```bash
# Start shell
oneiric shell

# In shell:
Oneiric> config.server_name
'Oneiric Config Server'

Oneiric> show_layers()
# Displays configuration layer table

Oneiric> validate_config()
✓ Configuration is valid

Oneiric> reload_settings()
Settings reloaded
```

### Programmatic Usage

```python
import asyncio
from oneiric.shell import OneiricShell
from oneiric.core.config import load_settings

async def main():
    config = load_settings()
    shell = OneiricShell(config)
    shell.start()

asyncio.run(main())
```

## Dependencies

### Required

- `oneiric` (core package)
- `IPython` (interactive shell)
- `rich` (formatted output)
- `pydantic` (validation)
- `mcp` (Session-Buddy integration)

### Optional

- `session-buddy` (for session tracking)

 graceful degradation if unavailable)

## Future Enhancements

### Potential Additions

1. **Lifecycle Commands**
   - `show_lifecycle_state()` - Display component lifecycle
   - `show_active_resolvers()` - List active resolvers

2. **Configuration Commands**
   - `export_config()` - Export current config to YAML
   - `diff_layers()` - Show differences between layers

3. **Magic Commands**
   - `%config <path>` - Navigate config structure
   - `%validate <field>` - Validate specific field

4. **Tab Completion**
   - Config field paths
   - Layer names
   - Command history

## Status

✅ **Implementation Complete**

- OneiricShell class implemented
- CLI command added and tested
- Session tracking integrated
- Documentation complete
- All tests passing

## Verification Checklist

- ✅ OneiricShell class created
- ✅ Extends AdminShell base class
- ✅ Component metadata methods implemented
- ✅ Session tracking via SessionEventEmitter
- ✅ CLI command `oneiric shell` added
- ✅ Namespace helpers working
- ✅ Banner displays correctly
- ✅ No circular imports
- ✅ All tests passing
- ✅ Documentation complete
- ✅ Graceful degradation when Session-Buddy unavailable

## Notes

- Shell sessions are tracked even if user doesn't interact (startup creates session)
- Session tracking is fire-and-forget (doesn't block shell operations)
- If Session-Buddy MCP is unavailable, shell still functions normally
- Configuration reload affects entire shell namespace
- Rich tables require terminal with color support (falls back gracefully)
