messaging-service (7004)
- Sends to Matrix
- Publishes NATS: messaging.message.created
↓
NATS (4222)
↓
agent-filter (7005)
- Applies rules (no loops, quiet hours, mapping)
- Publishes NATS: agent.filter.decision

NATS (4222)
↓
agent-runtime (7006)
- Loads agent blueprint (mock: Sofia-Prime)
- Reads channel history (50 messages)

## 🚀 How to Use
### Quick Start:
```bash
# 1. Start services
./scripts/start-phase2.sh
# 2. Run tests
./scripts/test-phase2-e2e.sh
# 3. Test in UI
# Open http://localhost:8899/messenger
# Type "Hello Sofia!"
# Wait 3-5 seconds
# See agent reply!
```
### Manual Start:
```bash
docker-compose -f docker-compose.agents.yml up -d --build
```
### Check Status:
```bash
# Services
docker ps | grep -E '(agent-filter|router|agent-runtime)'
# Logs
docker logs -f agent-filter
docker logs -f router
docker logs -f agent-runtime
# Health
curl http://localhost:7005/health
curl http://localhost:8000/health
curl http://localhost:7006/health
```

## 🐛 Known Limitations (Phase 2)
### Expected (By Design):
- ✅ Mock LLM responses (will be real in Phase 3)
- ✅ Mock agent blueprints (will be from agents-service in Phase 3)
- ✅ Memory service optional (will be required in Phase 3)
- ✅ Simple filtering rules (will be enhanced in Phase 2.5)
### Not Limitations:
- ✅ NATS integration works
- ✅ End-to-end flow works
- ✅ All services healthy
- ✅ Agent replies appear
---
## 💡 Key Learnings
### What Worked Well:
1. **Event-driven architecture** — Clean separation of concerns
2. **NATS pub/sub** — Reliable message delivery
3. **Graceful fallbacks** — Services work even if dependencies unavailable
4. **Mock implementations** — Allow testing without full stack
5. **Docker Compose** — Easy orchestration
### What to Improve:
1. Add metrics/monitoring
2. Add rate limiting
3. Improve error handling
4. Add retry logic
5. Add dead letter queue
