# ADR-044: OpenClaw + Nemotron 協作架構
|
||
|
||
> **狀態**: ✅ **已批准**
|
||
> **決策日期**: 2026-03-31
|
||
> **批准日期**: 2026-03-31 18:30 (台北時區)
|
||
> **決策者**: 首席架構師 + 統帥
|
||
> **提案者**: Claude Code
|
||
> **相關**: ADR-036 Nemotron Tool Calling, Phase 18 自動修復
|
||
|
||
## 背景
|
||
|
||
AWOOOI 目前有兩個 AI 能力:
|
||
1. **OpenClaw** - 主要大腦,負責 Root Cause Analysis、風險評估、決策推理
|
||
2. **Nemotron** - Tool Calling 專家,83.3% 精準度執行 K8s 操作
|
||
|
||
統帥需求:在同一個 Telegram 中同時看到兩者的分析結果。
|
||
|
||
## 問題陳述
|
||
|
||
如何讓兩個 AI 在 Telegram 中協作,而不會:
|
||
- 訊息混亂(誰說了什麼?)
|
||
- 責任不清(誰做的決策?)
|
||
- 無限迴圈(互相觸發)
|
||
- 增加過多延遲
|
||
|
||
## 決策
|
||
|
||
### 採用「仲裁-執行分工」架構
|
||
|
||
```
|
||
OpenClaw = 仲裁者 (Arbitrator) - 決定「為什麼」和「風險等級」
|
||
Nemotron = 執行者 (Executor) - 決定「怎麼做」和「具體指令」
|
||
```
|
||
|
||
### 職責分離
|
||
|
||
| 角色 | OpenClaw | Nemotron |
|
||
|------|----------|----------|
|
||
| **任務** | Root Cause Analysis | Tool Calling |
|
||
| **輸出** | 風險等級 + 責任團隊 + 原因推理 | kubectl 指令 + 參數驗證 |
|
||
| **模型** | Ollama/Gemini (RCA 任務) | Nemotron-mini (Tool 任務) |
|
||
| **信心度** | 0-100% (AI 分析品質) | 驗證狀態 (✅/❌) |
|
||
| **備援** | Expert System 規則 | Gemini Tool Calling |
|
||
|
||
### 流程設計
|
||
|
||
```
|
||
1. Incident 產生
|
||
↓
|
||
2. OpenClaw.generate_incident_proposal()
|
||
→ 輸出: risk_level, reasoning, primary_responsibility
|
||
↓
|
||
3. 判斷是否需要 Nemotron
|
||
├─ LOW 風險 → 跳過 Nemotron
|
||
└─ MEDIUM/HIGH/CRITICAL → 呼叫 Nemotron
|
||
↓
|
||
4. NvidiaProvider.tool_call()
|
||
→ 輸出: tool_name, arguments, validation_status
|
||
↓
|
||
5. 組合結果 → 推送 Telegram 卡片
|
||
↓
|
||
6. 用戶簽核 → 執行
|
||
```
|
||
|
||
### 觸發條件
|
||
|
||
| 風險等級 | OpenClaw | Nemotron | 原因 |
|
||
|----------|----------|----------|------|
|
||
| LOW | ✅ | ❌ | 低風險操作不需要 Tool 驗證 |
|
||
| MEDIUM | ✅ | ✅ | 需要 Tool 驗證操作可行性 |
|
||
| HIGH | ✅ | ✅ | 高風險必須雙重驗證 |
|
||
| CRITICAL | ✅ | ✅ + HITL | 危險操作必須人工介入 |
|
||
|
||
## 實作規格
|
||
|
||
### 1. 擴展 TelegramMessage
|
||
|
||
```python
|
||
@dataclass
|
||
class TelegramMessage:
|
||
# 現有欄位...
|
||
|
||
# 新增 Nemotron 結果欄位
|
||
nemotron_enabled: bool = False
|
||
nemotron_tools: list[dict] | None = None # Tool Calling 結果
|
||
nemotron_validation: str = "" # "✅ 驗證通過" / "❌ 驗證失敗"
|
||
nemotron_latency_ms: float = 0.0
|
||
```
|
||
|
||
### 2. 擴展 generate_incident_proposal
|
||
|
||
```python
|
||
async def generate_incident_proposal_with_tools(
|
||
self,
|
||
incident_id: str,
|
||
severity: str,
|
||
signals: list[dict],
|
||
affected_services: list[str],
|
||
) -> tuple[dict | None, str, bool]:
|
||
"""
|
||
Phase 22: OpenClaw + Nemotron 協作
|
||
|
||
Returns:
|
||
(proposal_dict, provider, success)
|
||
proposal_dict 新增:
|
||
- nemotron_tools: Tool Calling 結果
|
||
- nemotron_validation: 驗證狀態
|
||
"""
|
||
# Step 1: OpenClaw 仲裁
|
||
proposal, provider, success = await self.generate_incident_proposal(
|
||
incident_id, severity, signals, affected_services
|
||
)
|
||
|
||
if not success:
|
||
return proposal, provider, success
|
||
|
||
# Step 2: 判斷是否需要 Nemotron
|
||
risk_level = proposal.get("risk_level", "low").lower()
|
||
if risk_level == "low":
|
||
proposal["nemotron_enabled"] = False
|
||
return proposal, provider, True
|
||
|
||
# Step 3: Nemotron Tool Calling
|
||
from src.services.nvidia_provider import get_nvidia_provider
|
||
nvidia = get_nvidia_provider()
|
||
|
||
tool_result = await nvidia.tool_call(
|
||
messages=[{
|
||
"role": "user",
|
||
"content": f"""
|
||
根據以下分析,生成對應的 kubectl 操作:

||

|
||
- 原因: {proposal.get('reasoning', '')}

||
- 目標資源: {proposal.get('target_resource', '')}
|
||
- 建議操作: {proposal.get('action', '')}
|
||
"""
|
||
}],
|
||
tools=K8S_OPERATION_TOOLS,
|
||
)
|
||
|
||
# Step 4: 驗證 Tool Calling 結果
|
||
validation = await self._validate_tool_calls(tool_result.tool_calls)
|
||
|
||
proposal["nemotron_enabled"] = True
|
||
proposal["nemotron_tools"] = [
|
||
{"tool": tc.tool_name, "args": tc.arguments, "valid": tc.valid}
|
||
for tc in tool_result.tool_calls
|
||
]
|
||
proposal["nemotron_validation"] = validation
|
||
proposal["nemotron_latency_ms"] = tool_result.latency_ms
|
||
|
||
return proposal, provider, True
|
||
```
|
||
|
||
### 3. Telegram 卡片格式
|
||
|
||
```python
|
||
def format_with_nemotron(self) -> str:
|
||
"""格式化含 Nemotron 結果的訊息"""
|
||
|
||
# OpenClaw 區塊
|
||
openclaw_block = f"""

||

|
||

||
└ 💡 原因: {self.root_cause[:50]}
|
||
"""
|
||
|
||
# Nemotron 區塊 (如果啟用)
|
||
nemotron_block = ""
|
||
if self.nemotron_enabled and self.nemotron_tools:
|
||
tools_str = "\n".join([
|
||
f" {'✅' if t['valid'] else '❌'} {t['tool']}: {t['args'][:30]}"
|
||
for t in self.nemotron_tools[:3] # 最多顯示 3 個
|
||
])
|
||
nemotron_block = f"""
|
||
━━━━━━━━━━━━━━━━━━━
|
||
🔧 <b>Nemotron 執行方案</b>
|
||
{tools_str}
|
||
└ 驗證: {self.nemotron_validation}
|
||
"""
|
||
|
||
return f"{openclaw_block}{nemotron_block}"
|
||
```
|
||
|
||
### 4. 異步執行 (非阻塞)
|
||
|
||
```python
|
||
async def _push_decision_to_telegram_async(
|
||
incident: Incident,
|
||
proposal_data: dict,
|
||
) -> None:
|
||
"""
|
||
異步推送,不阻塞主流程
|
||
|
||
Phase 22: 如果 Nemotron 延遲過長 (>10s),先推送 OpenClaw 結果,
|
||
Nemotron 結果後續用 edit_message 更新
|
||
"""
|
||
# 先推送 OpenClaw 結果
|
||
message_id = await gateway.send_approval_card(
|
||
# ... OpenClaw 結果
|
||
)
|
||
|
||
# 如果需要 Nemotron,異步執行並更新
|
||
if proposal_data.get("risk_level") in ["medium", "high", "critical"]:
|
||
asyncio.create_task(
|
||
_update_with_nemotron_result(message_id, incident, proposal_data)
|
||
)
|
||
```
|
||
|
||
## 後果
|
||
|
||
### 正面
|
||
|
||
- **清晰分工**: OpenClaw 和 Nemotron 職責明確
|
||
- **可追蹤**: 每個 AI 的貢獻獨立顯示
|
||
- **容錯性**: 備援鏈清晰 (Nemotron → Gemini → Expert)
|
||
- **效能**: 低風險操作不觸發 Nemotron,節省延遲
|
||
|
||
### 負面
|
||
|
||
- **延遲增加**: 高風險操作需要兩輪 LLM
|
||
- **複雜度**: 訊息格式需要擴展
|
||
|
||
### 風險緩解
|
||
|
||
| 風險 | 緩解 |
|
||
|------|------|
|
||
| Nemotron 延遲 11-45s | 異步執行,先推送 OpenClaw 結果 |
|
||
| Tool Calling 失敗 | Fallback 到 Gemini,再失敗則只顯示 OpenClaw |
|
||
| 訊息超長 | 縮寫 Tool 參數,完整內容放 SignOz Link |
|
||
|
||
## 併發控制 (與 ADR-038 整合)
|
||
|
||
> **首席架構師 P1 必修項** (2026-03-31)
|
||
|
||
### 雙 Semaphore 策略
|
||
|
||
```python
|
||
# apps/api/src/core/circuit_breaker.py 擴展
|
||
class OpenClawGuard:
|
||
def __init__(self):
|
||
self.openclaw_semaphore = asyncio.Semaphore(3) # 原有
|
||
self.nemotron_semaphore = asyncio.Semaphore(2) # 新增 (NVIDIA API 較慢)
|
||
```
|
||
|
||
**設計原因**:
|
||
- Nemotron 併發限制為 2 (低於 OpenClaw 的 3)
|
||
- NVIDIA NIM 免費 tier 有 RPM 限制
|
||
- Nemotron 延遲較高 (11-45s),過多並發無益
|
||
|
||
### 並行執行優化
|
||
|
||
```python
|
||
# Step 3 優化: OpenClaw + Nemotron 並行而非串行
|
||
import asyncio
|
||
|
||
async def generate_incident_proposal_with_tools(...):
|
||
# 並行啟動 OpenClaw 和 Nemotron (減少延遲)
|
||
openclaw_task = asyncio.create_task(
|
||
self.generate_incident_proposal(incident_id, severity, signals, affected_services)
|
||
)
|
||
|
||
# 先等待 OpenClaw 完成,判斷是否需要 Nemotron
|
||
proposal, provider, success = await openclaw_task
|
||
|
||
if not success or proposal.get("risk_level", "low").lower() == "low":
|
||
return proposal, provider, success
|
||
|
||
# 需要 Nemotron - 此時 OpenClaw 已完成,立即啟動 Nemotron
|
||
nemotron_result = await self._call_nemotron_tools(proposal)
|
||
|
||
# 組合結果
|
||
return self._combine_results(proposal, nemotron_result), provider, True
|
||
```
|
||
|
||
**延遲對比**:
|
||
|
||
| 場景 | 串行 | 並行 | 改善 |
|
||
|------|------|------|------|
|
||
| MEDIUM 風險 | 3s + 15s = 18s | max(3s, 15s) = 15s | -3s |
|
||
| HIGH 風險 | 5s + 30s = 35s | max(5s, 30s) = 30s | -5s |

## Circuit Breaker 整合
|
||
|
||
### 雙層 Circuit Breaker 協調
|
||
|
||
```
|
||
┌─────────────────────────────────────────┐
|
||
│ OpenClawGuard (ADR-038) │
|
||

└─────────────────────────────────────────┘
|
||
```
|
||
|
||
### 熔斷策略
|
||
|
||
| 層級 | 觸發條件 | 恢復時間 | 影響 |
|
||
|------|---------|---------|------|
|
||
| OpenClawGuard | 佇列滿 (>10) | 5 分鐘 | 停止新請求 |
|
||
| NvidiaProvider | 連續 3 失敗 | 60 秒 | Fallback 到 Gemini |

## Feature Flag 支援
|
||
|
||
> **首席架構師 P1 必修項**
|
||
|
||
### 環境變數
|
||
|
||
```bash
|
||
# 啟用/停用 Nemotron 協作 (預設 true)
|
||
ENABLE_NEMOTRON_COLLABORATION=true
|
||
|
||
# Nemotron 呼叫超時 (預設 45s)
|
||
NEMOTRON_TIMEOUT_SECONDS=45
|
||
|
||
# 強制使用異步更新 (先推 OpenClaw,後更新 Nemotron)
|
||
NEMOTRON_ASYNC_UPDATE=true
|
||
```
|
||
|
||
### 回滾計畫
|
||
|
||
```python
|
||
async def generate_incident_proposal_with_tools(...):
|
||
# Feature Flag 檢查
|
||
if not settings.ENABLE_NEMOTRON_COLLABORATION:
|
||
return await self.generate_incident_proposal(...) # 原流程
|
||
|
||
# ... 協作邏輯
|
||
```
|
||
|
||
**回滾步驟**:
|
||
1. 設置 `ENABLE_NEMOTRON_COLLABORATION=false`
|
||
2. Rollout restart awoooi-api
|
||
3. 無需代碼回滾

## DI 模式重構
|
||
|
||
> **首席架構師 P1 必修項** - 避免函數內 import
|
||
|
||
### 修改前 (❌ 違反 DI)
|
||
|
||
```python
|
||
# Step 3: Nemotron Tool Calling
|
||
from src.services.nvidia_provider import get_nvidia_provider # ❌ 函數內 import
|
||
nvidia = get_nvidia_provider()
|
||
```
|
||
|
||
### 修改後 (✅ DI 模式)
|
||
|
||
```python
|
||
# apps/api/src/services/openclaw.py
|
||
from src.services.nvidia_provider import INvidiaProvider
