+## 📋 Phase 2 Specification (Agent Integration)
+
+### Components to Build
+
+#### 1. agent_filter Service
+**Location:** `services/agent-filter/`
+
+**Purpose:** Security and routing layer for agent messages
+
+**Endpoints:**
+- `POST /internal/filter/message` — Filter incoming message
+- `GET /internal/filter/rules/{microdao_id}` — Get rules
+
+**Logic:**
+```python
+def filter_message(event: MessageCreatedEvent) -> FilterDecision:
+    # Check permissions
+    if not is_agent_member(event.channel_id, "agent:sofia"):
+        return deny("not_member")
+    
+    # Check content
+    if contains_spam(event.content):
+        return deny("spam")
+    
+    # Check rate limit
+    if too_frequent(event.channel_id):
+        return deny("rate_limit")
+    
+    # Select agent
+    agent = select_best_agent(event)
+    return allow(agent.id)
+```
+
+**NATS:**
+- Subscribe: `messaging.message.created`
+- Publish: `agent.filter.decision`
+
+---
+
+#### 2. DAGI Router Extension
+**Location:** `services/dagi-router/`
+
+**Add routing rules:**
+```yaml
+rules:
+  - name: messaging.inbound
+    trigger: agent.filter.decision
+    condition: decision == 'allow'
+    action:
+      type: invoke_agent
+      agent_id: "{{ target_agent_id }}"
+      entrypoint: channel_message
+```
+
+**Actions:**
+- Parse `agent.filter.decision` events
+- Create `AgentInvocation`
+- Send to Agent Runtime
+
+---
+
+#### 3. Agent Runtime Channel Integration
+**Location:** `services/agent-runtime/`
+
+**Add channel context reader:**
+```python
+async def read_channel_context(channel_id: str, limit: int = 50):
+    # Call messaging-service internal API
+    messages = await http.get(
+        f"/internal/messaging/channels/{channel_id}/messages?limit={limit}"
+    )
+    return messages
+
+async def post_agent_reply(agent_id: str, channel_id: str, text: str):
+    # Call messaging-service internal API
+    await http.post(
+        f"/internal/agents/{agent_id}/post-to-channel",
+        json={"channel_id": channel_id, "text": text}
+    )
+```
+
+**Agent Execution Flow:**
+1. Receive invocation from DAGI Router
+2. Read channel context (last 50 messages)
+3. Query Agent Memory (RAG)
+4. Build prompt (system + context + memory)
+5. Call LLM Proxy
+6. Execute tools (if needed)
+7. Post reply via messaging-service
+
+---
+
+#### 4. messaging-service Extensions
+
+**Add internal endpoints:**
+
+**GET /internal/messaging/channels/{channel_id}/messages**
+```python
+@app.get("/internal/messaging/channels/{channel_id}/messages")
+async def get_channel_messages_internal(
+    channel_id: UUID,
+    limit: int = 50,
+    conn = Depends(get_db)
+):
+    # No auth (internal only)
+    messages = await conn.fetch(
+        "SELECT * FROM messages WHERE channel_id = $1 LIMIT $2",
+        channel_id, limit
+    )
+    return [dict(m) for m in messages]
+```
+
+**Already implemented:**
+```python
+@app.post("/internal/agents/{agent_id}/post-to-channel")
+async def agent_post_to_channel(...):
+    # Implemented in Phase 1 ✅
+```
+
+---
+
+#### 5. NATS Event Publishing
+
+**Update messaging-service:**
+```python
+import nats
+
+nats_client = await nats.connect(NATS_URL)
+
+# After indexing message:
+await nats_client.publish(
+    "messaging.message.created",
+    json.dumps({
+        "channel_id": str(channel_id),
+        "matrix_event_id": matrix_event_id,
+        "sender_id": sender_id,
+        "sender_type": sender_type,
+        "microdao_id": microdao_id,
+        "created_at": created_at.isoformat()
+    }).encode()
+)
+```
+
+**Update matrix-gateway:**
+```python
+# After receiving Matrix event:
+await nats_client.publish(
+    "integration.matrix.message",
+    json.dumps({
+        "room_id": room_id,
+        "event_id": event_id,
+        "sender_matrix_id": sender,
+        "type": event_type,
+        "content": content
+    }).encode()
+)
+```
