## 🔧 Technical Implementation Details

### Email Agent Architecture
```
Gmail API → OAuth2 → Read emails
         → Parse (from, subject, body)
         → Claude classifier (5 categories)
         → Route → [Auto-reply | Escalate | Route | Log]
         → SendGrid API → Send response
         → SQLite → Log transaction
```

### Telefon Agent Architecture
```
Twilio → Flask webhook → Inbound call handler
      → IVR greeting + menu
      → DTMF input → Route handling
      → Voice input → Whisper STT
      → Claude → Intent + response generation
      → OpenAI TTS → Play response
      → SQLite → Log call + transcript
      → Optional: Outbound callback
```

### Database Schemas Implemented

**Email Agent Tables:**
- `email_log` (13 columns) — incoming emails + classification + action taken
- `email_templates` (6 columns) — configurable response templates
- `email_queue` (8 columns) — pending outgoing emails

**Telefon Agent Tables:**
- `call_log` (14 columns) — all call details + transcripts + resolutions
- `ivr_interactions` (3 columns) — DTMF digit presses tracking
- `call_stats` (5 columns) — daily statistics aggregation
