+
+## 💡 核心功能
+
+### 1. 端到端自动化流程
+
+```
+用户需求 → PM 分析 → QA 设计测试 → Dev 编码 → 自动测试 → 验证输出
+```
+
+### 2. TDD（测试驱动开发）
+
+- QA Agent 先于代码生成测试用例
+- Dev Agent 编写代码确保测试通过
+- 测试失败时触发自动修复循环
+
+### 3. 自愈能力
+
+系统检测到测试失败时，自动：
+1. 分析错误日志
+2. 定位 bug 原因
+3. 生成修复代码
+4. 重新验证测试
+
+### 4. 人机协同
+
+关键节点支持人工确认：
+- SRS 文档审核
+- 测试用例评审
+- 最终代码验收
+
+### 5. 实时可视化
+
+Streamlit 前端提供：
+- 实时对话展示
+- Agent 状态监控
+- 工作流进度跟踪
+- 对话历史导出
+
+## 🔧 配置说明
+
+### 模型配置
+
+在 `config/llm_config.py` 中配置：
+
+```python
+DASHSCOPE_API_KEY = "your_api_key"
+DASHSCOPE_BASE_URL = "https://dashscope.aliyuncs.com/compatible-mode/v1"
+```
+
+### 支持的模型
+
+- `qwen3.5-flash` (推荐，速度快)
+- `qwen-max` (最强性能)
+- `qwen-plus` (平衡性能和成本)
+- `qwen-turbo` (最快速度)
+
+### Agent 系统提示词
+
+每个 Agent 都有专属的系统提示词，定义在 `config/llm_config.py` 中：
+
+- `PM_PROMPT` - 产品经理提示词
+- `QA_PROMPT` - 测试工程师提示词
+- `DEV_PROMPT` - 开发工程师提示词
+- `ORCH_PROMPT` - 协调器提示词
+
+## 📖 使用示例
+
+### 示例 1: 使用命令行
+
+```python
+from autogen_sdls_system import AutoGenSDLCSystem
+
+system = AutoGenSDLCSystem(api_key="your_key")
+
+requirement = "开发一个电池健康状态预测 API"
+result = system.run_workflow(requirement, max_round=15)
+
+print(result["summary"])
+```
+
+### 示例 2: 单独调用 Agent
+
+```python
+from agents import ProductManagerAgent
+
+pm = ProductManagerAgent(api_key="your_key")
+srs = pm.generate_srs("我需要一个车载蓝牙管理模块")
+print(srs)
+```
+
+### 示例 3: 自定义配置
+
+```python
+from config.llm_config import get_llm_config
+
+llm_config = get_llm_config(
+    model="qwen-max",
+    temperature=0.5,
+    max_tokens=4096
+)
+```
+
+## 🎬 Workshop 演示脚本
+
+### 场景：电池健康状态 (SOH) 预测 API
+
+1. **输入模糊需求**
+   ```
+   "我需要一个电池健康预测功能"
+   ```
+
+2. **PM Agent 输出** - 完整 SRS 文档
+   - 功能性需求
+   - 非功能性需求
+   - 验收标准
+
+3. **QA Agent 输出** - Pytest 测试脚本
+   - 测试函数
+   - BDD 场景描述
+
+4. **Dev Agent 输出** - 可运行的 API 代码
+   - 核心业务逻辑
+   - 错误处理
+
+5. **自动测试** - 展示测试执行和修复循环
+
+6. **最终输出** - 可部署的代码包 + 测试报告
+
+## ✅ 演示亮点
+
+- ✅ 实时展示 Agent 协作对话
+- ✅ 人机协同确认节点
+- ✅ 测试失败→自动修复→通过的闭环
+- ✅ 符合汽车行业标准（MISRA-C、ISO 26262）
+
+## 🐛 常见问题
+
+### Q1: API Key 无效
+
+**解决**: 检查环境变量是否正确设置
+
+```bash
+# 验证环境变量
+echo $DASHSCOPE_API_KEY  # Linux/Mac
+echo %DASHSCOPE_API_KEY% # Windows CMD
+```
+
+### Q2: 模型响应超时
+
+**解决**: 增加超时时间或降低 `max_tokens`
+
+```python
+llm_config = get_llm_config(timeout=180)
+```
+
+### Q3: 测试执行失败
+
+**解决**: 检查工作目录权限和 pytest 安装
+
+```bash
+pip install pytest
+chmod +x workspace/
+```
+
+## 📊 日志与导出
+
+### 对话日志
+
+所有对话自动保存在 `logs/` 目录：
+
+- JSONL 格式：`session_YYYYMMDD_HHMMSS.jsonl`
+- JSON 导出：`conversation_*.json`
+- Markdown 导出：`conversation_*.md`
+
+### 导出方法
+
+```python
+system.export_conversation("my_conversation.json")
+system.export_report("my_report.md")
+```
+
+## 🔐 安全建议
+
+1. **不要硬编码 API Key** - 使用环境变量
+2. **审查生成的代码** - AI 可能产生不安全代码
+3. **限制执行权限** - 禁用 Docker 或使用沙箱
+4. **定期清理 workspace** - 避免敏感数据积累

+1. ✅ **每个 Agent 当前在做什么** (任务标签实时显示)
+2. ✅ **Agent 之间的对话流** (类似微信/QQ 聊天界面)
+3. ✅ **当前发言的 Agent** (绿色高亮 + 脉冲动画)
+4. ✅ **对话传递关系** (箭头指示下一个 Agent)
+
+## 🚀 启动方法
+
+```bash
+streamlit run frontend/streamlit_app_v3.py
+```
+
+## 🎨 界面说明
+
+### 1. Agent 状态行 (顶部)
+```

+
+**特点**:
+- 💬 **彩色气泡** = 不同 Agent 有不同颜色
+- 📝 **任务徽章** = 每个消息都显示当前任务
+- ⬇️ **传递箭头** = 显示工作流转向下一个 Agent
+- 🕐 **时间戳** = 精确到秒的发言时间
+
+## 🎭 Agent 颜色方案
+
+| Agent | 颜色 | 气泡样式 |
+|-------|------|---------|
+| 📋 PM Agent | 🔵 蓝色 | 蓝色渐变 |
+| ✅ QA Agent | 🟢 绿色 | 绿色渐变 |
+| 💻 Dev Agent | 🟠 橙色 | 橙色渐变 |
+| 🎯 Orchestrator | 🟣 紫色 | 紫色渐变 |
+| 👤 User Proxy | 🟤 棕色 | 棕色渐变 |
+
+## 📊 实时任务标签
+
+每个 Agent 的任务会动态更新：
+
+### PM Agent 任务流
+1. `待命` → 初始状态
+2. `启动流程` → 收到 Orchestrator 指令
+3. `需求分析` → 分析用户需求
+4. `生成 SRS` → 编写需求文档
+5. `待命` → 完成任务
+
+### QA Agent 任务流
+1. `待命` → 初始状态
+2. `测试设计` → 阅读 SRS
+3. `编写测试` → 创建 test_*.py
+4. `TDD 实践` → 确保测试先行
+5. `待命` → 完成任务
+
+### Dev Agent 任务流
+1. `待命` → 初始状态
+2. `代码实现` → 阅读 SRS 和测试
+3. `编写代码` → 创建 src_*.py
+4. `修复 bug` → 测试失败时
+5. `待命` → 完成任务
+
+## 🔍 对话流示例
+
+完整的 SDLC 对话流会是这样：
+
+```
+👤 用户代理 [提出需求]
+  "我需要一个电池健康状态预测 API"
+        ⬇️ 传递给 协调器
+
+🎯 协调器 [启动流程]
+  "🚀 启动 SDLC 工作流！开始协作..."
+        ⬇️ 传递给 产品经理
+
+📋 产品经理 [需求分析]
+  "收到！分析需求中...
+   功能性需求：
+   1. 接收电压/电流/温度数据
+   2. 计算 SOH 百分比
+   3. 异常检测..."
+        ⬇️ 传递给 测试工程师
+
+✅ 测试工程师 [测试设计]
+  "基于 SRS 设计测试用例...
+   test_normal_operation()
+   test_zero_voltage()..."
+        ⬇️ 传递给 开发工程师
+
+💻 开发工程师 [代码实现]
+  "开始编写代码...
+  实现 calculate_soh() 函数...
+  符合 PEP8 规范..."
+        ⬇️ 传递给 用户代理
+
+👤 用户代理 [测试执行]
+  "执行测试...
+  ✅ test_normal_operation PASSED
+  ✅ test_zero_voltage PASSED..."
+        ⬇️ 传递给 协调器
+
+🎯 协调器 [总结完成]
+  "✅ SDLC 流程完成！
+  生成文件：SRS.md, test_battery_health.py..."
+```
+
+## 💡 使用技巧
+
+### 1. 实时追踪特定 Agent
+- 看**顶部状态行** → 哪个 Agent 绿色高亮就是在发言
+- 看**任务标签** → 了解该 Agent 具体在做什么
+- 看**消息数量** → 知道哪个 Agent 最活跃
+
+### 2. 理解对话流
+- 看**气泡颜色** → 快速识别是哪个 Agent
+- 看**传递箭头** → 理解工作流方向
+- 看**时间戳** → 了解执行顺序
+
+### 3. 调试问题
+- 如果某个 Agent **一直不说话** → 可能是模型配置问题
+- 如果**对话卡住** → 检查 API Key 和网络
+- 如果**任务标签不更新** → 刷新页面重试
+
+## 🆚 与 v2 的区别
+
+| 特性 | v2 | v3 (新版) |
+|------|----|-----------|
+| Agent 状态 | 静态卡片 | 动态高亮 + 任务标签 |
+| 对话展示 | 普通列表 | 聊天气泡流 |
+| 任务追踪 | ❌ 无 | ✅ 实时显示 |
+| 传递关系 | ❌ 无 | ✅ 箭头指示 |
+| 当前发言 | ⚪ 小圆点 | 🟢 绿色高亮 + 横幅 |
+
+## 🎬 演示场景
+
+### 场景 1: 电池健康预测 API
+1. 输入需求："我需要一个电池健康状态预测 API"
+2. 点击"启动对话流"
+3. 观察 5 个 Agent 的协作过程
+4. 查看每个 Agent 的任务变化
+5. 最终生成 3 个文件
+
+### 场景 2: 车牌识别系统
+1. 输入需求："开发一个车牌识别系统"
+2. 启动对话流
+3. 看 PM 如何分析需求
+4. 看 QA 如何设计测试
+5. 看 Dev 如何实现代码
+
+## 📥 导出功能
+
+点击侧边栏的"📥 导出对话"，可以保存完整的对话历史为 JSON 格式，包含：
+- 每个 Agent 的发言内容
+- 发言时间戳
+- 当时的任务状态
+- 对话顺序
+
+## 🐛 注意事项
+
+1. **确保安装依赖**: `pip install streamlit pyautogen dashscope`
+2. **设置 API Key**: `$env:DASHSCOPE_API_KEY="your_key"`
+3. **网络稳定**: 需要稳定的网络连接访问阿里云 API
+4. **耐心等待**: 大模型生成需要时间，每轮约 10-30 秒

+# AutoGen SDLC 系统 - 问题修复说明
+
+## 🔧 已修复的问题
+
+### 问题：Streamlit 运行时报错 `'TERMINAL'`
+
+**错误现象**:
+```
+错误：'TERMINAL'
+```
+
+**根本原因**:
+`UserProxyAgent` 的 `human_input_mode="TERMINAL"` 设置会在 Web 环境下尝试使用终端输入，导致 Streamlit 报错。
+
+**解决方案**:
+将所有文件中的 `human_input_mode="TERMINAL"` 改为 `human_input_mode="NEVER"`。
+
+### 修改的文件
+
+1. ✅ `frontend/streamlit_app_v2.py` (第 224 行)
+2. ✅ `frontend/streamlit_app.py` (第 104 行)
+3. ✅ `autogen_sdls_system.py` (第 115 行)
