## 🚀 What Was Delivered

### 1. Complete API Implementation

#### Core Components

- ✅ **PromptAdapterSettings** - Configuration with Oneiric patterns
- ✅ **PromptBackend** - Abstract interface with lifecycle methods
- ✅ **PromptAdapter** - Wrapper class for direct instantiation
- ✅ **create_prompt_adapter()** - Factory function with auto-detection

#### Backends

- ✅ **PyObjC Backend** (macOS native dialogs)

  - NSAlert for dialog boxes
  - NSUserNotification for system notifications
  - NSOpenPanel for file selection
  - ThreadPoolExecutor management

- ✅ **Prompt-Toolkit Backend** (cross-platform terminal UI)

  - Rich terminal prompts
  - Async/await support
  - Keyboard shortcuts
  - Multiple file selection

### 2. Lifecycle Management

```python
# Method 1: Explicit lifecycle
adapter = create_prompt_adapter()
await adapter.initialize()
try:
    await adapter.notify("Hello!")
finally:
    await adapter.shutdown()

# Method 2: Context manager (recommended)
async with create_prompt_adapter() as adapter:
    await adapter.notify("Hello!")
```

### 3. Configuration Options

#### Environment Variables

```bash
export MCP_COMMON_PROMPT_BACKEND=pyobjc
export MCP_COMMON_PROMPT_TIMEOUT=60
export MCP_COMMON_PROMPT_TUI_THEME=dark
```

#### Python Configuration

```python
from mcp_common.prompting import PromptAdapterSettings

settings = PromptAdapterSettings(
    backend="pyobjc",
    timeout=60,
)
```

### 4. Comprehensive Documentation

#### README.md

- Quick start guide (3 methods)
- Complete API reference
- Backend comparison table
- Platform-specific notes
- Usage examples

#### MIGRATION.md

- Step-by-step migration guide
- Breaking changes analysis (none!)

______________________________________________________________________

## 🔄 Backward Compatibility

### Zero Breaking Changes

All old code continues to work:

```python
# Old code still works!
from mcp_common.prompting import create_prompt_adapter, PromptConfig

config = PromptConfig(backend="pyobjc")
adapter = create_prompt_adapter(config=config)
result = await adapter.confirm("Continue?")
```

### New Code (Recommended)

```python
# New patterns available
from mcp_common.prompting import create_prompt_adapter, PromptAdapterSettings

async with create_prompt_adapter() as adapter:
    result = await adapter.confirm("Continue?")
```
