-# EasyFlow Chat Protocol Specification v1.1
-
-* **Protocol Name:** `easyflow-chat`
-* **Version:** `1.1`
-* **Status:** Draft / Recommended
-* **Transport:** Server-Sent Events (SSE)
-* **Encoding:** UTF-8
-
-
-
-## 1. 设计背景与目标
-
-本协议用于描述 **EasyFlow 对话系统中的服务端事件流通信规范**，支持：
-
-* AI 对话的 **流式输出**
-* 模型 **思考过程（Thinking）**
-* **工具调用（Tool Calling）**
-* **系统 / 业务错误**
-* **工作流 / Agent 状态**
-* **对话中的用户交互（表单、确认等）**
-* **中断与恢复（Suspend / Resume）**
-
-设计目标：
-
-* 前后端解耦
-* 协议长期可扩展
-* 不绑定具体模型厂商
-* 易于与 Workflow / Agent / Chain 架构集成
-
-
-
-## 2. 传输层规范（Transport）
-
-* 使用 HTTP + SSE（支持未来扩展为其他协议，比如 WebSocket 等）
-* Response Header：
-
-  ```http
-  Content-Type: text/event-stream
-  Cache-Control: no-cache
-  Connection: keep-alive
-  ```
-* 通信方向：**Server → Client**
-* 所有业务数据通过 `data` 字段传输，格式为 **JSON 字符串**
-
-
-
-## 3. SSE Event 级别规范
-
-### 3.1 Event Name（固定）
-
-| event   | 含义    |
-| - |-------|
-| message | 正常业务事件 |
-| error   | 错误事件  |
-| done    | 流结束事件 |
-
-> ⚠️ **禁止在 event name 中承载业务语义**
-
-
-
-## 4. 统一 Envelope 结构（核心）
-
-### 4.1 基本结构
-
-```json
-{
-  "protocol": "easyflow-chat",
-  "version": "1.1",
-  "domain": "llm | tool | system | business | workflow | interaction | debug",
-  "type": "string",
-  "conversation_id": "string",
-  "message_id": "string",
-  "index": 0,
-  "payload": {},
-  "meta": {}
-}
-```
-
-
-
-### 4.2 字段说明
-
-| 字段              | 类型      | 必填 | 说明                     |
-| -- |---------| -- |------------------------|
-| protocol        | string  | ✔  | 固定值 `easyflow-chat` |
-| version         | string  | ✔  | 协议版本                   |
-| domain          | string  | ✔  | 事件所属领域                 |
-| type            | string  | ✔  | 领域内事件类型                |
-| conversation_id | string  | ✔  | 会话唯一标识                 |
-| message_id      | string  | ✖  | assistant 消息 ID        |
-| index           | number  | ✖  | 流式输出序号                 |
-| payload         | object  | ✔  | 事件数据                   |
-| meta            | object  | ✖  | 元信息（token、耗时等）         |
-
-
-
-## 5. Domain 定义
-
-| Domain      | 说明             |
-| -- | -- |
-| llm         | 模型语义输出         |
-| tool        | 工具调用与结果        |
-| system      | 系统级事件          |
-| business    | 业务规则           |
-| workflow    | 工作流 / Agent 状态 |
-| interaction | 用户交互（表单等）      |
-| debug       | 调试信息           |
-
-
-
-## 6. llm Domain
-
-### 6.1 thinking
-
-表示模型的思考过程。
-
-#### 流式输出（delta）
-
-```json
-{
-  "domain": "llm",
-  "type": "thinking",
-  "payload": {
-    "delta": "分析用户需求"
-  }
-}
-```
-
-#### 完整输出（可选）
-
-```json
-{
-  "domain": "llm",
-  "type": "message",

-    "tool_call_id": "call_1",
-    "name": "search",
-    "arguments": {
-      "query": "SSE 协议设计"
-    }
-  }
-}
-```
-
-
-
-### 7.2 tool_result

-    "result": {}
-  }
-}
-```
-
-

-}
-```
-
-
-
-### 8.2 status
-
-```json
-{
-  "domain": "system",
-  "type": "status",
-  "payload": {
-    "state": "initializing | running | suspended | resumed"
-  }
-}
-```
-
-
-
-## 9. business Domain
-
-```json
-{
-  "domain": "business",
-  "type": "error",

-    "code": "QUOTA_EXCEEDED",
-    "message": "配额不足"
-  }
-}
-```
-
-
-
-## 10. workflow Domain
-
-```json
-{
-  "domain": "workflow",
-  "type": "status",
-  "payload": {
-    "node_id": "node_1",
-    "state": "start | suspend | resume | end",
-    "reason": "interaction"
-  }
-}
-```
-
-
-
-## 11. interaction Domain（对话内交互）
-
-### 11.1 form_request
-
-表示请求用户填写表单，对话进入挂起状态。
-
-```json
-{
-  "domain": "interaction",
-  "type": "form_request",
-  "payload": {
-    "form_id": "user_info_form",
-    "title": "补充信息",
-    "description": "请填写以下信息以继续",
-    "schema": {
-      "type": "object",
-      "required": ["age", "email"],
-      "properties": {
-        "age": {
-          "type": "number",
-          "title": "年龄"
-        },
-        "email": {
-          "type": "string",
-          "title": "邮箱",
-          "format": "email"
-        }
-      }
-    },
-    "ui": {
-      "submit_text": "继续",
-      "cancel_text": "取消"
-    }
-  }
-}
-```
-
-> 表单 schema **符合 JSON Schema 标准**
-
-
-
-### 11.2 form_cancel
-
-```json
-{
-  "domain": "interaction",
-  "type": "form_cancel",
-  "payload": {
-    "form_id": "user_info_form"
-  }
-}
-```
-
-
-
-## 12. 表单提交与恢复（非 SSE）
-
-表单提交通过 **普通 HTTP / WebSocket 请求**：
-
-```json
-{
-  "conversation_id": "conv_1",
-  "form_id": "user_info_form",
-  "values": {
-    "age": 30,
-    "email": "a@b.com"
-  }
-}
-```
-
-成功后服务端恢复 SSE 流。
-
-
-
-## 13. done 事件（流结束）
-
-```json
-{
-  "domain": "system",
-  "type": "done",
-  "meta": {
-    "prompt_tokens": 1234,
-    "completion_tokens": 456,
-    "latency_ms": 2300
-  }
-}
-```
-
-
-
-## 14. 错误处理规则
-
-* 收到 `event: error` 后客户端应终止流
-* 错误语义由：
-
-  ```
-  domain + type + payload.code
-  ```
-
-  共同决定
-
-
-
-## 15. 状态机视角（推荐）
-
-```text
-RUNNING
-  ↓
-LLM_OUTPUT
-  ↓
-INTERACTION_REQUESTED
-  ↓
-SUSPENDED
-  ↓
-FORM_SUBMITTED
-  ↓
-RESUMED
-  ↓
-RUNNING
-  ↓
-DONE
-```
-
-
-
-## 16. 扩展与兼容规则
-
-1. 可新增 domain
-2. 可新增 type
-3. 不允许删除已有字段
-4. payload 可自由扩展
-5. 1.x 版本保持向后兼容
-
-
-
-## 17. 设计原则
-
-> * SSE 只负责事件流
-> * domain 定义责任边界
-> * type 定义语义动作
-> * payload 定义数据结构
-> * 前端不依赖 event name 判断业务，不依赖协议本身，支持其他协议的扩展
