**Total: 9 files (6 new, 3 updated) | ~2,500 lines of production code**

## System Capabilities

### 1. Follow-Up Nudge Detector

**Purpose:** Automatically identify emails that need responses

**Detection Criteria:**
- Emails from 3-7 days ago

```
Opportunity: "Project Update from John Doe needs a response (5 days ago)"
Evidence: "Can you provide an update on the project status?"
Action: Generate email draft reply
```

### 2. Daily Brief Detector

**Purpose:** Generate comprehensive morning digest
