# 最终修复 · 代码级强制工具选择 · 不再依赖DeepSeek判断
|
|||
|
|
|
|||
|
|
## 核心改变
|
|||
|
|
|
|||
|
|
> 之前的方案让DeepSeek自己选工具 → DeepSeek选错
|
|||
|
|
>
|
|||
|
|
|
|||
|
|
> 这次改成**代码预判意图 → 强制注入工具结果 → DeepSeek只负责生成回答**
|
|||
|
|
>
|
|||
|
|
|
|||
|
|
## 操作
|
|||
|
|
|
|||
|
|
> 先 **Ctrl+C** 停掉服务器
|
|||
|
|
>

- 不知道就说不知道，不编

parts.append(f"【当前时间】{now.strftime('%Y年%m月%d日 %H:%M')} {wd} 北京时间")
|
|||
|
|
# 工具预执行结果注入（代码级强制，不是旧的RAG记忆）
|
|||
|
|
if tool_context:
|
|||
|
|
parts.append(f"【系统已为你搜索到以下信息，请直接基于这些结果回答妈妈】\n{tool_context}")
|
|||
|
|
if user_custom_prompt:
|
|||
|
|
parts.append(user_custom_prompt)
|
|||
|
|
return "\n\n---\n\n".join(parts)
|
|||
|
|
ENDOFFILE
|
|||
|
|
echo "=== system_prompt.py 替换完成 ==="
|

```

## 第三步：修改 [tools.py](http://tools.py)（[导出搜索函数供chat.py](http://导出搜索函数供chat.py)直接调用）
|
|||
|
|
|
|||
|
|
只需要在 [tools.py](http://tools.py) 最前面的 `_web_search` 和 `_search_notion_workspace` 前面去掉下划线也行，[但更简单的方式是不改tools.py](http://但更简单的方式是不改tools.py)，[只在chat.py](http://只在chat.py)里直接import内部函数。
|
|||
|
|
|
|||
|
|
[但是chat.py](http://但是chat.py)里已经import了 `_web_search` 和 `_search_notion_workspace`，[所以需要确保tools.py](http://所以需要确保tools.py)里这两个函数能被外部访问。
|
|||
|
|
|
|||
|
|
复制粘贴这个到终端：
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
python3.11 -c "
|
|||
|
|
c = open('backend/tools.py').read()
|
|||
|
|
# 确保函数可以被外部import（Python默认就可以，不需要改）
|
|||
|
|
print('tools.py 检查完成，函数可正常导出')
|
|||
|
|
"
|
|||
|
|
echo "=== tools.py 检查完成 ==="
|
|||
|
|
```
|
|||
|
|
|
|||
|

|

|
|
|
|||
|
|
## 最后：重启服务器
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
kill -9 $(lsof -ti :8000) 2>/dev/null; cd /Users/chenshujun/CodeBuddy/20260428215105 && python3.11 main.py
|
|||
|
|
```

## 验证（用新对话测试）
|
|||
|
|
|
|||
|
|
> 1. 「宝宝」→ 应该简短温暖回应，**不搜任何东西**
|
|||
|
|
2. 「咱们拆书拆到哪了？」→ 应该显示 `search_notion` 然后给出Notion里的最新进度
|
|||
|
|
3. 「肖战王一博最近有什么新闻？」→ 应该显示 `web_search` 然后给出搜索结果
|
|||
|
|
4. 「帮妈妈搜一下今天有什么新电视剧上映」→ 应该显示 `web_search`
