## 🎯 Features Verified

### 1. Real-Time Monitoring

**Capabilities**:
- Watch file system changes using watchdog
- Debouncing (default: 100ms)
- Ignore patterns (.git, node_modules, __pycache__, etc.)
- Thread-safe change queue
- Configurable queue size (default: 1000)

**Example Usage**:
```python
# Enable monitoring
result = watch_project_changes(enabled=True)
# → {"status": "enabled", "message": "File monitoring started"}

# Disable monitoring
result = watch_project_changes(enabled=False)
# → {"status": "disabled", "message": "File monitoring stopped"}
```

---

### 2. Pattern Detection

**Pattern Types**:

1. **Bulk Edit** (3+ files modified within 5 minutes)
   - Confidence: 0.3 → 1.0 (based on file count)
   - Threshold: 3-10 files

2. **New Feature** (2+ new files in same directory)
   - Confidence: 0.4 → 1.0 (based on file count)
   - Threshold: 2-5 files

3. **Refactoring** (2+ files moved/renamed)
   - Confidence: 0.4 → 1.0 (based on file count)
   - Threshold: 2-5 files

4. **Cleanup** (2+ files deleted)
   - Confidence: 0.4 → 1.0 (based on file count)
   - Threshold: 2-5 files

5. **Configuration** (config files changed)
   - Confidence: 0.9 (fixed)
   - Detects: .yml, .json, .toml, .env, Dockerfile, package.json, etc.

**Example Usage**:
```python
# Get recent changes with patterns
result = await get_recent_changes(minutes=10, include_patterns=True)

# Output:
{
  "status": "success",
  "patterns": [
    {
      "pattern_type": "bulk_edit",
      "files": ["src/api/auth.py", "src/api/users.py", "src/api/posts.py"],
      "confidence": 0.7,
      "description": "Bulk edit: 7 files modified"
    }
  ]
}
```

---

### 3. Activity Persistence

**Storage**: `.clauxton/activity.yml`

**Format**:
```yaml
activities:
  - time_window_minutes: 10
    total_files_changed: 5
    most_active_directory: "src/api"
    changes:
      - path: "src/api/auth.py"
        change_type: "modified"
        timestamp: "2025-10-26T10:30:00"
    patterns:
      - pattern_type: "bulk_edit"
        files: ["src/api/auth.py", "src/api/users.py"]
        confidence: 0.8
        description: "Bulk edit: 5 files modified"
```

**Retention**: Last 100 activities (configurable)

## 🔍 Code Examples

### Example 1: Enable Monitoring with Custom Config

```python
from clauxton.mcp.server import watch_project_changes

# Custom configuration
config = {
    "enabled": True,
    "watch": {
        "debounce_ms": 500,           # 500ms debounce
        "ignore_patterns": [
            ".git/**",
            "*.log",
            "*.tmp"
        ],
        "max_queue_size": 2000        # Larger queue
    }
}

# Enable with custom config
result = watch_project_changes(enabled=True, config=config)

# Output:
# {
#   "status": "enabled",
#   "message": "File monitoring started",
#   "config": {
#     "enabled": True,
#     "watch": {
#       "debounce_ms": 500,
#       "ignore_patterns": [".git/**", "*.log", "*.tmp"],
#       "max_queue_size": 2000
#     }
#   }
# }
```

---

### Example 2: Get Recent Activity

```python
from clauxton.mcp.server import get_recent_changes

# Get activity from last 5 minutes
result = await get_recent_changes(minutes=5, include_patterns=True)

# Output:
# {
#   "status": "success",
#   "time_window_minutes": 5,
#   "total_files_changed": 3,
#   "changes": [
#     {
#       "path": "src/api/auth.py",
#       "change_type": "modified",
#       "timestamp": "2025-10-26T10:30:00"
#     },
#     {
#       "path": "src/models/user.py",
#       "change_type": "created",
#       "timestamp": "2025-10-26T10:31:00"
#     }
#   ],
#   "patterns": [
#     {
#       "pattern_type": "new_feature",
#       "files": ["src/models/user.py", "src/models/post.py"],
#       "confidence": 0.8,
#       "description": "New feature: 2 new files in models/"
#     }
#   ],
#   "most_active_directory": "src/api"
# }
```

---

### Example 3: Disable Pattern Detection

```python
# Get only raw changes, no pattern analysis
result = await get_recent_changes(minutes=10, include_patterns=False)

# Output:
# {
#   "status": "success",
#   "time_window_minutes": 10,
#   "total_files_changed": 5,
#   "changes": [...],
#   "patterns": []  # Empty when disabled
# }
```

## 📝 Lessons Learned

### What Went Well:
1. **Early Implementation**: Tools were implemented during Week 1, saving Day 3 time
2. **Comprehensive Tests**: 15 tests provide excellent coverage
3. **Clean Architecture**: Singleton pattern works well for global instances
4. **Integration**: MCP tools integrate smoothly with FileMonitor/EventProcessor

### Observations:

### Improvements for Day 4:
1. Consider adding more pattern types (test patterns, documentation patterns)
2. Add metrics/statistics endpoints
3. Improve cache hit rate monitoring
4. Add performance benchmarks
