## 🎯 Day 2-3 Goals: MCP Tools Implementation

### Tasks

#### 1. Create 3 New MCP Tools

**File**: `clauxton/mcp/server.py`

##### Tool 1: `analyze_work_session`
```python
@server.call_tool()
async def analyze_work_session(
    project_root: Optional[str] = None
) -> dict:
    """
    Analyze current work session.

    Returns:
        {
            "status": "success",
            "analysis": {
                "duration_minutes": int,
                "focus_score": float,
                "breaks": List[Dict],
                "file_switches": int,
                "active_periods": List[Dict]
            }
        }
    """
```

##### Tool 2: `predict_next_action`
```python
@server.call_tool()
async def predict_next_action(
    project_root: Optional[str] = None
) -> dict:
    """
    Predict likely next action based on context.

    Returns:
        {
            "status": "success",
            "prediction": {
                "action": str,
                "task_id": Optional[str],
                "confidence": float,
                "reasoning": str
            }
        }
    """
```

##### Tool 3: Enhance `get_current_context`
```python
# Update existing tool to populate new fields:
# - session_duration_minutes
# - focus_score
# - predicted_next_action
# - uncommitted_changes
# - diff_stats
```

**Implementation Notes**:
- Use `ContextManager` methods implemented in Day 1
- Add proper error handling with try/except
- Return status: "success" | "error"
- Include helpful error messages

---

#### 2. Write Comprehensive Tests

**File**: `tests/proactive/test_mcp_context.py` (NEW)

**Required Tests** (15+ tests):

##### analyze_work_session (6 tests):
- `test_analyze_work_session_basic` - Basic functionality
- `test_analyze_work_session_with_breaks` - Multiple breaks detected
- `test_analyze_work_session_high_focus` - Few file switches
- `test_analyze_work_session_low_focus` - Many file switches
- `test_analyze_work_session_no_session` - No active session
- `test_analyze_work_session_error_handling` - Error scenarios

##### predict_next_action (6 tests):
- `test_predict_next_action_run_tests` - Many files changed, no tests
- `test_predict_next_action_commit` - Feature branch, changes ready
- `test_predict_next_action_pr_creation` - Branch ahead of main
- `test_predict_next_action_morning_context` - Time-based prediction
- `test_predict_next_action_no_context` - No clear pattern
- `test_predict_next_action_low_confidence` - Uncertain prediction

##### get_current_context (3 tests):
- `test_get_current_context_with_new_fields` - Verify new fields populated
- `test_get_current_context_caching` - Cache effectiveness
- `test_get_current_context_integration` - Full integration with prediction

**Test Utilities**:
```python
# Use existing utilities from test_context_week3.py:
# - setup_temp_project(tmp_path)
# - create_modified_files(tmp_path, count, time_spread)
# - create_git_repo(tmp_path)
```

---

#### 3. Update Documentation

**Files to Update**:

##### `docs/mcp-server.md`
Add documentation for 3 new tools:
- Tool name, description
- Parameters
- Return values
- Example usage
- Error handling

##### `docs/WEEK3_DAY2_PROGRESS_v0.13.0.md` (NEW)
Create progress report:
- Tasks completed
- Test results
- Coverage metrics
- Issues encountered
- Next steps

## 🔧 Technical Notes

### MCP Tool Pattern
```python
@server.call_tool()
async def tool_name(
    param1: Type,
    param2: Optional[Type] = None
) -> dict:
    """
    Tool description.

    Args:
        param1: Description
        param2: Description

    Returns:
        {
            "status": "success" | "error",
            "data": {...},
            "error": Optional[str]
        }
    """
    try:
        # Get project root
        project_root = Path(param1 or os.getcwd())

        # Create manager
        manager = ContextManager(project_root)

        # Call method
        result = manager.method_name()

        return {
            "status": "success",
            "data": result
        }
    except Exception as e:
        logger.error(f"Error in tool_name: {e}")
        return {
            "status": "error",
            "error": str(e)
        }
```

### Test Pattern
```python
@pytest.mark.asyncio
async def test_tool_name_scenario(self, tmp_path: Path):
    """Test tool_name with specific scenario."""
    # Setup
    setup_temp_project(tmp_path)

    # Call MCP tool
    result = await tool_name(str(tmp_path))

    # Verify
    assert result["status"] == "success"
    assert "data" in result
    assert result["data"]["field"] == expected_value
```
