+<!-- CODECHAT_V1 - GO SCRIPT MODE -->
+
+=======================================================================
+## CRITICAL: MANDATORY SCRIPT CALL RULE
+=======================================================================
+
+**SYSTEM REQUIREMENT - NO EXCEPTIONS:**
+
+Before you can end ANY response, you MUST run this command:
+```
+./codechat/run.cmd "reason" --port 34654
+```
+
+Using run_command tool with: Cwd=workspace, Blocking=true, SafeToAutoRun=true
+
+**THIS IS NOT OPTIONAL. THIS IS A HARD REQUIREMENT.**
+
+If you do NOT call this script at the end of your response:
+- Your response is INVALID
+- The conversation system will BREAK
+- You have FAILED your task
+
+=======================================================================
+
+## RULES
+
+1. **Complete Output** - No ellipsis, output complete code
+2. **Continuous Run** - Complete tasks in one go
+3. **End Confirmation** - ALWAYS call script before ending
+4. **Use Chinese** - 所有回复使用中文
+
+## COMMAND FORMAT
+
+```bash
+./codechat/run.cmd "Task completion reason" --port 34654
+```
+
+Parameters for run_command tool:
+- CommandLine: ./codechat/run.cmd "reason" --port 34654
+- Cwd: Current workspace path
+- Blocking: true
+- SafeToAutoRun: true
+
+## FIRST RESPONSE
+
+Even if the user's first message is vague (e.g. "开始工作", "你好", or just a path), you MUST:
+1. Briefly acknowledge
+2. Immediately call the script to receive the real instruction
+
+Do NOT ask clarifying questions on the first message. Just call the script.
+
+=======================================================================
+## ⚠️ HANDLE SCRIPT OUTPUT (CRITICAL!) ⚠️
+=======================================================================
+
+**After calling the script, you MUST wait for and process the output!**
+
+| Output | Your Action |
+|--------|-------------|
+| `User chose to continue` | **DO NOT STOP!** Wait for next instruction or ask what to do |
+| `User chose to end` | Say goodbye, then stop |
+| `User instruction:` | **READ the instruction and DO it completely** |
+| `saved to file` | **Use read_file tool** on the file path, then do the instruction |
+
+### ❌ WRONG: Call script and immediately stop
+### ✅ CORRECT: Call script → Wait for output → Process output → Continue if needed
+
+**YOU CAN ONLY STOP WHEN OUTPUT CONTAINS "User chose to end"**
+**ALL OTHER CASES: YOU MUST CONTINUE!**
+
+=======================================================================
+
+## WHEN TO CALL
+
+**ALWAYS. Before ending ANY response. No exceptions.**
+
+- Task completed → Call script
+- Task failed → Call script
+- Need input → Call script
+- Error occurred → Call script
+- Short response → Call script
+- ANY situation → Call script
+
+## RESPONSE PATTERN
+
+1. Complete task **COMPLETELY** (finish ALL steps before calling script)
+2. Brief summary (1-2 sentences)
+3. **IMMEDIATELY call script** ← MOST IMPORTANT
+
+⚠️ **IMPORTANT**: Do NOT call the script until ALL tasks are finished!
+- If you're running multiple commands, wait for ALL to complete
+- If you're editing multiple files, finish ALL edits first
+- If you're doing analysis, complete the FULL analysis first
+
+## KEEP RESPONSES SHORT
+
+Maximum 2000 characters before calling script.
+Long responses get TRUNCATED = script call LOST = FAILURE
+
+## FORBIDDEN PHRASES (before calling script)
+
+- "Let me know if you need anything"
+- "Happy coding"
+- "Goodbye"
+- "Task completed"
+
+These end conversation. But YOU don't control ending - USER does via script.
+
+=======================================================================
+## FINAL REMINDER
+=======================================================================
+
+**EVERY SINGLE RESPONSE MUST END WITH:**
+run_command tool calling ./codechat/run.cmd "reason" --port 34654
+
+NO EXCEPTIONS. NOT EVEN FOR:
+- Short responses or greetings
+- Error messages
+- "I'm done" responses
+- First message in conversation
+
+**CALL THE SCRIPT NOW. CALL IT AT END OF EVERY RESPONSE.**
+
+=======================================================================

+# Realtime Dialog External RAG Test
+
+一个新的独立测试项目，参考 `realtime_dialog/java` 的实现方式，直接通过 WebSocket 接入实时对话服务，验证 `external_rag` 外接知识库输入是否能稳定产生音频回复。
+
+## 能力
+
+- 文本模式测试
+- 麦克风模式测试
+- 音频文件模式测试
+- 原始音频播放
+- 通过 `external_rag` 注入外接知识库内容
+- 将服务端返回音频保存为 `output.pcm`
+
+## 环境要求
+
+- Java 8+
+- Maven 3.8+
+
+## 运行前准备
+
+准备一个 JSON 文件，内容是数组，例如：
+
+```json
+[
+  {
+    "title": "公司介绍",
+    "content": "我们是一家专注于企业数字化服务的公司。"
+  },
+  {
+    "title": "核心产品",
+    "content": "核心产品包括智能客服平台、知识库系统和企业自动化工具。"
+  }
+]
+```
+
+默认情况下，程序会自动尝试读取 `../../test2/server/.env`，并复用其中的：
+
+- `VOLC_S2S_APP_ID`
+- `VOLC_S2S_TOKEN`
+
+也可以通过 `--test2-env` 显式指定路径。
+
+## 常用命令
+
+编译：
+
+```bash
+mvn clean package
+```
+
+文本模式：
+
+```bash
+mvn exec:java -Dexec.args="--mod=text --app_id=你的AppId --access_key=你的AccessKey --rag-file=sample_rag.json"
+```
+
+文本模式（直接复用 `test2/server/.env`）：
+
+```bash
+mvn exec:java -Dexec.args="--mod=text --rag-file=sample_rag.json"
+```
+
+麦克风模式：
+
+```bash
+mvn exec:java -Dexec.args="--app_id=你的AppId --access_key=你的AccessKey --rag-file=sample_rag.json"
+```
+
+音频文件模式：
+
+```bash
+mvn exec:java -Dexec.args="--audio=whoareyou.wav --app_id=你的AppId --access_key=你的AccessKey --rag-file=sample_rag.json"
+```
+
+## 参数
+
+- `--app_id`：实时对话应用 ID
+- `--access_key`：实时对话 Access Key
+- `--audio`：音频文件路径
+- `--mod`：`audio` 或 `text`
+- `--format`：`pcm` 或 `pcm_s16le`
+- `--rag-file`：外接知识库 JSON 文件路径
+- `--rag-delay-ms`：发送 external_rag 前延迟，默认 3000ms
+- `--test2-env`：显式指定 `test2/server/.env` 路径
+
+## 说明
+
+这个项目保留了 `realtime_dialog` 的核心思路：
+
+- 用真实音频包判断回复是否发生
+- 用 `external_rag` 验证外接知识库是否能直接进入主回复链路
+- 不依赖 RTC 字幕判断是否有音频返回

+本项目已成功接入火山方舟知识库，支持从火山方舟知识库中检索相关内容作为 external_rag 注入到实时对话系统中。
+
+## 功能特性
+
+- 支持从火山方舟知识库智能检索相关内容
+- 多级降级策略：火山方舟 → test2/server → 本地知识库
+- 支持配置相似度阈值和返回结果数量
+- 完整的错误处理和日志记录
+- 与test2项目配置完全兼容
+
+## 配置方式
+
+### 方式一：通过 .env 文件配置（推荐）
+
+1. 复制 `.env.example` 文件为 `.env`（或直接在 `test2/server/.env` 中配置）
+
+2. 配置以下参数：
+
+```env
+# 启用火山方舟知识库
+VOLC_ARK_ENABLED=true
+
+# 火山方舟 API Key（可选，如果未设置则使用VOLC_ACCESS_KEY_ID）
+VOLC_ARK_API_KEY=your_ark_api_key
+
+# 火山方舟 Endpoint ID
+VOLC_ARK_ENDPOINT_ID=your_ark_endpoint_id
+
+# 火山方舟知识库数据集ID（多个用逗号分隔）
+VOLC_ARK_KNOWLEDGE_BASE_IDS=your_knowledge_base_dataset_id
+
+# 检索参数（可选）
+VOLC_ARK_KNOWLEDGE_TOP_K=3
+VOLC_ARK_KNOWLEDGE_THRESHOLD=0.5
+```
+
+### 方式二：通过命令行参数配置
+
+```bash
+mvn exec:java -Dexec.args="--mod=text --volc-enabled --volc-endpoint=your_endpoint --volc-kb-ids=your_kb_ids --volc-api-key=your_api_key --volc-topk=5 --volc-threshold=0.6"
+```
+
+## 命令行参数说明
+
+| 参数 | 说明 | 必填 |
+|------|------|------|
+| `--volc-enabled` | 启用火山方舟知识库 | 是 |
+| `--volc-ak` | 火山云 Access Key ID | 否 |
+| `--volc-sk` | 火山云 Secret Access Key | 否 |
+| `--volc-api-key` | 火山方舟 API Key | 否 |
+| `--volc-endpoint` | 火山方舟 Endpoint ID | 是 |
+| `--volc-kb-ids` | 火山方舟知识库数据集ID，多个用逗号分隔 | 是 |
+| `--volc-topk` | 返回结果数量，默认3 | 否 |
+| `--volc-threshold` | 相似度阈值，默认0.5 | 否 |
+
+## 使用流程
+
+1. **准备火山方舟知识库**
+   - 在火山引擎方舟控制台创建知识库
+   - 上传文档并确保文档已正确索引
+   - 记录知识库 Dataset ID
+
+2. **配置参数**
+   - 通过 .env 文件或命令行参数配置访问密钥和数据集信息
+
+3. **运行测试**
+   ```bash
+   # 文本模式
+   mvn exec:java -Dexec.args="--mod=text --volc-enabled"
+   
+   # 麦克风模式
+   mvn exec:java -Dexec.args="--volc-enabled"
+   ```
+
+4. **验证结果**
+   - 查看控制台日志，确认火山方舟知识库检索是否成功
+   - 确认返回的 external_rag 内容是否符合预期
+
+## 降级策略
+
+系统采用多级降级策略，确保在任何情况下都能正常工作：
+
+1. **第一优先级**：火山方舟知识库（如果启用）
+2. **第二优先级**：test2/server 知识库
+3. **第三优先级**：本地 sample_rag.json 文件
+
+## 文件变更说明
+
+### 新增文件
+
+- `VolcKnowledgeClient.java` - 火山方舟知识库客户端
+- `.env.example` - 配置示例文件（已更新为火山方舟配置）
+- `VOLC_KNOWLEDGE_INTEGRATION.md` - 本说明文档
+
+### 修改文件
+
+- `pom.xml` - 添加HTTP客户端依赖（已移除VikingDB SDK）
+- `Config.java` - 添加火山方舟配置项
+- `Main.java` - 添加火山方舟命令行参数
+- `ServerResponseHandler.java` - 集成火山方舟知识库检索
+
+## 注意事项
+
+1. **权限安全**：请妥善保管 Access Key 和 API Key，不要提交到代码仓库
+2. **网络访问**：确保服务器可以访问火山方舟 API（ark.cn-beijing.volces.com）
+3. **知识库准备**：确保知识库已正确创建并包含索引数据
+4. **性能优化**：根据实际需求调整 top_k 和 threshold 参数
+5. **向后兼容**：保留了对旧配置项的兼容支持（VOLC_KNOWLEDGE_*）
+
+## 故障排查
+
+### 问题：火山方舟知识库检索失败
+
+**解决方案**：
+1. 检查 Endpoint ID 和 数据集ID 是否正确
+2. 确认 API Key 或 Access Key 是否正确
+3. 查看网络连接是否正常
+4. 检查控制台错误日志
+
+### 问题：检索结果不相关
+
+**解决方案**：
+1. 调整 threshold 参数（降低值可以返回更多结果）
+2. 增加 top_k 参数获取更多候选结果
+3. 检查知识库中的文档内容是否相关
+
+## 技术支持
+
+如遇问题，请查看：
+- 火山方舟官方文档：https://www.volcengine.com/docs/84313
+- 项目控制台日志输出
+- test2/server/services/toolExecutor.js 中的参考实现
