🔄 Complete Flow

User types "Hello Sofia!" in Messenger
    ↓
messaging-service → Matrix → NATS: messaging.message.created
    ↓
agent-filter: Rules check
  - Block agent loops ✅
  - Check quiet hours ✅
  - Map to agent:sofia ✅
    ↓
NATS: agent.filter.decision (allow)
    ↓
router: Create AgentInvocation
    ↓
NATS: router.invoke.agent
    ↓
agent-runtime:
  1. Load blueprint (mock: Sofia-Prime)
  2. Read 50 messages from channel
  3. Query memory (graceful fallback)
  4. Build LLM prompt
  5. Generate response (mock LLM for Phase 2)

🚀 How to Start

Option 1: Quick Start (Recommended)

# Start Phase 2 services
./scripts/start-phase2.sh

# Wait 10 seconds for health checks

# Run E2E tests
./scripts/test-phase2-e2e.sh

# Check logs
docker logs -f agent-filter
docker logs -f router
docker logs -f agent-runtime

Option 2: Manual

# Create network if needed
docker network create daarion

# Build and start
docker-compose -f docker-compose.agents.yml up -d --build

# Check status
docker ps

# Test endpoints
curl http://localhost:7005/health
curl http://localhost:8000/health
curl http://localhost:7006/health

---

🧪 Testing

Automated E2E Test

./scripts/test-phase2-e2e.sh

Tests:

1. ✅ Health checks (all 4 services)
2. ✅ Agent filter decision logic
3. ✅ Router invocation creation
4. ✅ NATS connection status
5. ✅ Internal endpoints

Manual Testing

Test agent-filter:

curl -X POST http://localhost:7005/internal/agent-filter/test \
  -H "Content-Type: application/json" \
  -d '{
    "channel_id": "7c72d497-27aa-4e75-bb2f-4a4a21d4f91f",
    "matrix_event_id": "$test123",
    "sender_id": "user:93",
    "sender_type": "human",
    "microdao_id": "microdao:daarion",
    "created_at": "2025-11-24T12:00:00Z"
  }'

# Expected: {"decision": "allow", "target_agent_id": "agent:sofia"}

Test router:

curl -X POST http://localhost:8000/internal/router/test-messaging \
  -H "Content-Type: application/json" \
  -d '{
    "channel_id": "test",
    "matrix_event_id": "$test",
    "microdao_id": "microdao:daarion",
    "decision": "allow",
    "target_agent_id": "agent:sofia"
  }'

# Expected: {"agent_id": "agent:sofia", "entrypoint": "channel_message", ...}

Test agent-runtime:

curl -X POST http://localhost:7006/internal/agent-runtime/test-channel \
  -H "Content-Type: application/json" \
  -d '{
    "agent_id": "agent:sofia",
    "entrypoint": "channel_message",
    "payload": {
      "channel_id": "7c72d497-27aa-4e75-bb2f-4a4a21d4f91f",
      "microdao_id": "microdao:daarion"
    }
  }'

# Expected: {"status": "processed", "agent_id": "agent:sofia"}

Real E2E Test (UI):

1. Open Messenger: http://localhost:8899/messenger
2. Select "DAARION City General" channel
3. Type: "Hello Sofia!"
4. Wait 3-5 seconds
5. ✅ See agent reply: "Привіт! Я Sofia..."

docker ps | grep nats

# Check NATS logs
docker logs nats

# Restart services
./scripts/stop-phase2.sh
./scripts/start-phase2.sh

Agent not replying?

# Check filter decision
docker logs -f agent-filter | grep "Decision"

# Check routing
docker logs -f router | grep "invocation"

# Check runtime
docker logs -f agent-runtime | grep "Agent.*replied"

# Check messaging-service is publishing
docker logs messaging-service | grep "Published to NATS"
