+```
+
+### Key Components
+
+**消息流程**: Webview -> `onDidReceiveMessage` -> `messageHandler.ts` -> 后端处理 -> `panel.webview.postMessage` -> Webview
+
+**消息类型** (`src/types/chatHistory.ts`):
+- `MessageType.SYSTEM` / `USER` / `AI` / `TOOL_EXECUTION_RESULT`
+- 兼容 LangChain4j 格式
+
+**iverilog 集成** (`tools/iverilog/`):
+- 内置 Windows x64 版本的 iverilog/vvp
+- 通过 `IVERILOG_ROOT` 环境变量配置库路径
+- 支持命令: "生成 VCD"、"运行仿真"、"生成波形"
+
+## VS Code Extension Points
+
+- 命令: `ic-coder.openPanel`, `ic-coder.openChat`, `ic-coder.openVCDViewer`
+- 侧边栏视图: `ic-coder.mainView`
+- 激活事件: `onLanguage:verilog`, `onLanguage:vhdl`, `onStartupFinished`
+
+## Dependencies
+
+- `vcdrom`, `vcd-stream`, `waveql` - VCD 波形处理
+- `@wavedrom/doppler`, `onml` - 波形渲染
+- `iconv-lite` - 编码转换
+
+## Notes
+
+- `webviewContent.ts` 和 `messageHandler.ts` 文件较大，建议使用搜索而非完整读取
+- 当前仅支持 Windows 平台的 iverilog，其他平台需用户自行安装

+# IC Coder 认证系统实现文档
+
+## 概述
+
+本文档详细说明了 IC Coder 插件如何集成 VSCode Authentication API，实现用户登录功能，并在 VSCode 左下角账户区域显示登录状态。
+
+## 架构设计
+
+### 核心组件
+
+1. **ICCoderAuthenticationProvider** - 认证提供者
+2. **VSCode Authentication API** - VSCode 官方认证接口
+3. **本地 HTTP 服务器** - 处理登录回调
+4. **ICViewProvider** - 侧边栏视图（根据登录状态显示不同按钮）
+
+### 工作流程
+
+```
+用户点击登录
+    ↓
+调用 vscode.authentication.getSession()
+    ↓
+ICCoderAuthenticationProvider.createSession()
+    ↓
+启动本地 HTTP 服务器（动态端口）
+    ↓
+打开浏览器访问登录页面
+    ↓
+用户在网站完成登录
+    ↓
+网站重定向到 http://localhost:{port}/callback?token=xxx
+    ↓
+本地服务器接收 token
+    ↓
+创建 AuthenticationSession
+    ↓
+VSCode 左下角显示账户信息
+```
+
+## 详细实现
+
+### 1. Authentication Provider 实现
+
+文件：`src/services/icCoderAuthProvider.ts`
+
+#### 1.1 类定义
+
+```typescript
+export class ICCoderAuthenticationProvider
+  implements vscode.AuthenticationProvider
+{
+  private _onDidChangeSessions =
+    new vscode.EventEmitter<vscode.AuthenticationProviderAuthenticationSessionsChangeEvent>();
+  public readonly onDidChangeSessions = this._onDidChangeSessions.event;
+
+  private _sessions: vscode.AuthenticationSession[] = [];
+}
+```
+
+**关键点：**
+
+- 实现 `vscode.AuthenticationProvider` 接口
+- 使用 `EventEmitter` 通知会话变化
+- 在内存中维护会话列表
+
+#### 1.2 核心方法
+
+##### getSessions() - 获取会话列表
+
+```typescript
+async getSessions(scopes?: readonly string[]): Promise<readonly vscode.AuthenticationSession[]> {
+  return this._sessions;
+}
+```
+
+##### createSession() - 创建会话（登录）
+
+```typescript
+async createSession(scopes: readonly string[]): Promise<vscode.AuthenticationSession> {
+  const token = await this.login();
+
+  const session: vscode.AuthenticationSession = {
+    id: this.generateSessionId(),
+    accessToken: token,
+    account: {
+      id: "iccoder-user",
+      label: "IC Coder 用户",
+    },
+    scopes: [...scopes],
+  };
+
+  this._sessions.push(session);
+  await this.saveSessions();
+
+  this._onDidChangeSessions.fire({
+    added: [session],
+    removed: [],
+    changed: [],
+  });
+
+  return session;
+}
+```
+
+**关键点：**
+
+- 调用 `login()` 方法获取 token
+- 创建 `AuthenticationSession` 对象
+- 保存到 `globalState`
+- 触发 `onDidChangeSessions` 事件通知 VSCode
+
+##### removeSession() - 删除会话（登出）
+
+```typescript
+async removeSession(sessionId: string): Promise<void> {
+  const sessionIndex = this._sessions.findIndex((s) => s.id === sessionId);
+  if (sessionIndex > -1) {
+    const session = this._sessions[sessionIndex];
+    this._sessions.splice(sessionIndex, 1);
+    await this.saveSessions();
+
+    this._onDidChangeSessions.fire({
+      added: [],
+      removed: [session],
+      changed: [],
+    });
+  }
+}
+```
+
+### 2. 本地 HTTP 服务器实现
+
+#### 2.1 动态端口分配
+
+```typescript
+server.listen(0, () => {
+  const address = server.address();
+  const port = typeof address === "object" && address ? address.port : 3000;
+  resolve({ server, port });
+});
+```
+
+**关键点：**
+
+- 使用端口 `0` 让系统自动分配可用端口
+- 避免端口冲突问题
+- 支持多个用户同时使用
+
+#### 2.2 回调处理
+
+```typescript
+if (url.pathname === "/callback") {
+  const token = url.searchParams.get("token");
+
+  if (token) {
+    // 返回成功页面
+    res.writeHead(200, { "Content-Type": "text/html; charset=utf-8" });
+    res.end(this.getSuccessPage(iconBase64));
+
+    // 关闭服务器
+    server.close();
+
+    // 返回 token
+    if ((server as any)._loginResolve) {
+      (server as any)._loginResolve(token);
+    }
+  }
+}
+```
+
+### 3. package.json 配置
+
+#### 3.1 注册 Authentication Provider
+
+```json
+{
+  "contributes": {
+    "authentication": [
+      {
+        "id": "iccoder",
+        "label": "IC Coder"
+      }
+    ]
+  }
+}
+```
+
+**关键点：**
+
+- `id` 必须与代码中使用的 ID 一致
+- `label` 会显示在 VSCode 账户菜单中
+
+#### 3.2 注册命令
+
+```json
+{
+  "contributes": {
+    "commands": [
+      {
+        "command": "ic-coder.login",
+        "title": "IC Coder: 登录账户",
+        "category": "IC Coder"
+      },
+      {
+        "command": "ic-coder.logout",
+        "title": "IC Coder: 退出登录",
+        "category": "IC Coder"
+      }
+    ]
+  }
+}
+```
+
+### 4. extension.ts 注册
+
+#### 4.1 注册 Authentication Provider
+
+```typescript
+export function activate(context: vscode.ExtensionContext) {
+  // 注册 Authentication Provider
+  const authProvider = new ICCoderAuthenticationProvider(context);
+  context.subscriptions.push(
+    vscode.authentication.registerAuthenticationProvider(
+      "iccoder",
+      "IC Coder",
+      authProvider
+    )
+  );
+}
+```
+
+#### 4.2 登录命令
+
+```typescript
+const loginCommand = vscode.commands.registerCommand(
+  "ic-coder.login",
+  async () => {
+    try {
+      await vscode.authentication.getSession("iccoder", [], {
+        createIfNone: true,
+      });
+    } catch (error) {
+      vscode.window.showErrorMessage(`登录失败: ${error}`);
+    }
+  }
+);
+```
+
+**关键点：**
+
+- `createIfNone: true` 会在没有会话时自动调用 `createSession()`
+- VSCode 会自动处理 UI 交互
+
+#### 4.3 登出命令
+
+```typescript
+const logoutCommand = vscode.commands.registerCommand(
+  "ic-coder.logout",
+  async () => {
+    try {
+      const session = await vscode.authentication.getSession("iccoder", [], {
+        createIfNone: false,
+      });
+      if (session) {
+        await vscode.authentication.getSession("iccoder", [], {
+          clearSessionPreference: true,
+          forceNewSession: true,
+        });
+        vscode.window.showInformationMessage("已退出登录");
+      }
+    } catch (error) {
+      vscode.window.showInformationMessage("当前未登录");
+    }
+  }
+);
+```
+
+### 5. ICViewProvider 集成
+
+#### 5.1 检查登录状态
+
+```typescript
+private async checkLoginStatus(): Promise<boolean> {
+  try {
+    const session = await vscode.authentication.getSession("iccoder", [], { createIfNone: false });
+    return !!session;
+  } catch (error) {
+    return false;
+  }
+}
+```
+
+#### 5.2 根据登录状态显示不同按钮
+
+```typescript
+resolveWebviewView(webviewView: vscode.WebviewView) {
+  this.checkLoginStatus().then((isLoggedIn) => {
+    webviewView.webview.html = this.getWebviewContent(
+      webviewView.webview,
+      isLoggedIn
+    );
+  });
+}
+```
+
+```typescript
+${isLoggedIn
+  ? '<button class="btn" onclick="openChat()">开始创作</button>'
+  : '<button class="btn" onclick="login()">登录账户</button>'
+}
+```
+
+### 6. 网站前端配置
+
+#### 6.1 检测插件登录请求
+
+```javascript
+// 在登录页面检测 redirect_uri 参数
+const urlParams = new URLSearchParams(window.location.search);
+const redirectUri = urlParams.get("redirect_uri");
+
+if (redirectUri) {
+  // 保存回调地址
+  localStorage.setItem("plugin_redirect_uri", redirectUri);
+}
+```
+
+#### 6.2 登录成功后重定向
+
+```javascript
+// 用户登录成功，拿到 token
+const token = response.data.token;
+
+// 检查是否需要重定向回插件
+const redirectUri = localStorage.getItem("plugin_redirect_uri");
+
+if (redirectUri) {
+  // 重定向回插件，带上 token
+  window.location.href = `${redirectUri}?token=${token}`;
+  localStorage.removeItem("plugin_redirect_uri");
+} else {
+  // 正常登录流程
+  router.push("/dashboard");
+}
+```
+
+## 关键技术点
+
+### 1. 动态端口分配
+
+**问题：** 固定端口可能被占用，导致登录失败
+
+**解决方案：** 使用端口 `0` 让系统自动分配可用端口
+
+```typescript
+server.listen(0, () => {
+  const address = server.address();
+  const port = typeof address === "object" && address ? address.port : 3000;
+});
+```
+
+### 2. Promise 异步等待
+
+**问题：** 需要等待浏览器登录完成后才能继续
+
+**解决方案：** 使用 Promise 包装回调逻辑
+
+```typescript
+return new Promise((resolve, reject) => {
+  (server as any)._loginResolve = resolve;
+  (server as any)._loginReject = reject;
+});
+```
+
+### 3. 会话持久化
+
+**问题：** 重启 VSCode 后需要重新登录
+
+**解决方案：** 使用 `globalState` 保存会话
+
+```typescript
+await this.context.globalState.update("icCoderSessions", this._sessions);
+```
+
+### 4. 事件通知机制
+
+**问题：** VSCode 需要知道会话状态变化
+
+**解决方案：** 使用 `EventEmitter` 触发事件
+
+```typescript
+this._onDidChangeSessions.fire({
+  added: [session],
+  removed: [],
+  changed: [],
+});
+```
+
+## 用户体验
+
+### 登录流程
+
+1. 用户点击侧边栏"登录账户"按钮
+2. 浏览器自动打开登录页面
+3. 用户在网站完成登录
+4. 浏览器自动跳转到成功页面
+5. VSCode 左下角显示"IC Coder 用户"
+6. 侧边栏按钮变为"开始创作"
+
+### 登出流程
+
+1. 点击 VSCode 左下角账户图标
+2. 选择"IC Coder"账户
+3. 点击"退出"按钮
+4. 或使用命令 `IC Coder: 退出登录`
+
+## 常见问题
+
+### Q1: 为什么不直接使用 globalState 存储 token？
+
+**A:** 使用 VSCode Authentication API 的优势：
+
+- ✅ 统一的用户体验（左下角账户区域）
+- ✅ VSCode 自动管理会话生命周期
+- ✅ 支持多账户切换
+- ✅ 更好的安全性（VSCode 负责加密存储）
+
+### Q2: 如何处理 token 过期？
+
+**A:** 可以在 API 请求失败时：
+
+1. 检测 401 错误
+2. 调用 `removeSession()` 清除过期会话
+3. 提示用户重新登录
+
+### Q3: 如何支持多个账户？
+
+**A:** 修改 `account` 对象：
+
+```typescript
+account: {
+  id: userInfo.id,
+  label: userInfo.username,
+}
+```
+
+### Q4: 登录页面如何获取用户信息？
+
+**A:** 可以在登录成功后，通过 API 获取用户信息：
+
+```typescript
+const userInfo = await fetch("https://api.iccoder.com/user/info", {
+  headers: { Authorization: `Bearer ${token}` },
+});
+
+const session: vscode.AuthenticationSession = {
+  account: {
+    id: userInfo.id,
+    label: userInfo.username,
+  },
+  // ...
+};
+```
+
+## 安全考虑
+
+### 1. Token 存储
+
+- ✅ 使用 VSCode `globalState` 加密存储
+- ✅ 不在代码中硬编码敏感信息
+- ✅ Token 仅在内存和加密存储中传递
+
+### 2. 本地服务器
+
+- ✅ 仅监听 `localhost`，不暴露到外网
+- ✅ 使用动态端口，避免固定端口被劫持
+- ✅ 接收到 token 后立即关闭服务器
+- ✅ 设置 5 分钟超时，防止服务器长期运行
+
+### 3. HTTPS 考虑
+
+**当前实现：** 使用 HTTP 本地回调
+
+**生产环境建议：**
+
+- 网站使用 HTTPS
+- 本地回调使用 HTTP（localhost 不受浏览器限制）
+- 或使用 `vscode://` 协议（需要网站支持）
+
+## 测试指南
+
+### 1. 本地测试
+
+```bash
+# 启动调试模式
+按 F5
+
+# 测试登录
+1. 打开侧边栏
+2. 点击"登录账户"
+3. 在浏览器完成登录
+4. 检查左下角是否显示账户
+
+# 测试登出
+1. 点击左下角账户
+2. 选择"IC Coder"
+3. 点击"退出"
+```
+
+### 2. 调试技巧
+
+```typescript
+// 在 ICCoderAuthenticationProvider 中添加日志
+console.log("🔐 创建会话:", session);
+console.log("🔑 Token:", token);
+
+// 在 ICViewProvider 中添加日志
+console.log("🔍 登录状态:", isLoggedIn);
+```
+
+### 3. 常见错误排查
+
+| 错误                            | 原因            | 解决方案                           |
+| ------------------------------- | --------------- | ---------------------------------- |
+| `getSessions is not a function` | VSCode 版本过低 | 升级到 1.63.0+                     |
+| 端口被占用                      | 固定端口冲突    | 使用动态端口（已实现）             |
+| 登录后未显示账户                | 未触发事件      | 检查 `_onDidChangeSessions.fire()` |
+| 重启后需要重新登录              | 未保存会话      | 检查 `saveSessions()` 调用         |

+# IC Coder 会话存储技术文档
+
+## 1. 概述
+
+IC Coder 的会话存储系统负责持久化保存用户与 AI 的对话历史，支持多项目、多任务的会话管理。系统采用文件系统存储方案，将会话数据按项目和任务组织，便于管理和检索。
+
+### 1.1 核心特性
+
+- **多项目支持**：不同项目的会话数据独立存储
+- **任务级管理**：每个会话作为独立任务进行管理
+- **分页加载**：支持历史会话的分页查询，提升性能
+- **实时更新**：会话数据实时保存，防止数据丢失
+- **统计信息**：记录 Token 使用量、对话轮次等统计数据
+
+### 1.2 技术栈
+
+- **存储方式**：文件系统（JSON/JSONL 格式）
+- **存储位置**：`~/.iccoder/projects/{项目路径编码}/{taskId}/`
+- **数据格式**：
+  - `meta.json`：任务元数据
+  - `conversation.json`：完整对话历史
+  - `conversation_meta.jsonl`：对话轮次元数据（JSONL 格式）
+
+---
+
+## 2. 架构设计
+
+### 2.1 目录结构
+
+```
+~/.iccoder/
+└── projects/
+    └── {项目路径编码}/
+        └── {taskId}/
+            ├── meta.json              # 任务元数据
+            ├── conversation.json      # 对话历史
+            └── conversation_meta.jsonl # 对话元数据
+```
+
+**项目路径编码规则**：
+- 移除冒号 `:`
+- 将斜杠 `/` 和反斜杠 `\` 替换为 `--`
+- 示例：`C:\Users\admin\Documents\Project` → `C--Users--admin--Documents--Project`
+
+**任务 ID 格式**：
+- 格式：`task_{date}_{sequence}`
+- 示例：`task_20231226_a3f9k2`
+- `date`：8 位日期（YYYYMMDD）
+- `sequence`：6 位随机字符串
+
+### 2.2 核心类：ChatHistoryManager
+
+`ChatHistoryManager` 是会话存储的核心管理类，采用单例模式设计。
+
+**主要职责**：
+1. 管理会话存储目录
+2. 创建和切换任务
+3. 保存和加载对话历史
+4. 记录统计信息
+5. 提供会话历史查询接口
+
+**关键属性**：
+```typescript
+private static instance: ChatHistoryManager;
+private baseDir: string;                    // ~/.iccoder
+private currentTaskId: string | null;       // 当前任务 ID
+private currentProjectPath: string | null;  // 当前项目路径
+```
+
+---
+
+## 3. 数据模型
+
+### 3.1 TaskMeta（任务元数据）
+
+存储在 `meta.json` 文件中，记录任务的基本信息和统计数据。
+
+```typescript
+interface TaskMeta {
+  taskId: string;           // 任务 ID
+  taskName: string;         // 任务名称
+  projectPath: string;      // 项目路径
+  createdAt: string;        // 创建时间（ISO 8601）
+  updatedAt: string;        // 更新时间（ISO 8601）
+  stats: {
+    credits: number;        // 消耗的积分
+    totalTokens: number;    // 总 Token 数
+    inputTokens: number;    // 输入 Token 数
+    outputTokens: number;   // 输出 Token 数
+  };
+}
+```
+
+**示例**：
+```json
+{
+  "taskId": "task_20231226_a3f9k2",
+  "taskName": "实现计数器功能",
+  "projectPath": "C:\\Users\\admin\\Documents\\Project",
+  "createdAt": "2023-12-26T10:30:00.000Z",
+  "updatedAt": "2023-12-26T11:45:00.000Z",
+  "stats": {
+    "credits": 0,
+    "totalTokens": 15420,
+    "inputTokens": 8200,
+    "outputTokens": 7220
+  }
+}
+```
+
+### 3.2 ChatMessage（对话消息）
+
+存储在 `conversation.json` 文件中，记录完整的对话历史。
+
+**消息类型枚举**：
+```typescript
+enum MessageType {
+  USER = "USER",                           // 用户消息
+  AI = "AI",                               // AI 消息
+  SYSTEM = "SYSTEM",                       // 系统消息
+  TOOL_EXECUTION_RESULT = "TOOL_EXECUTION_RESULT"  // 工具执行结果
+}
+```
+
+**用户消息**：
+```typescript
+interface UserMessage {
+  type: MessageType.USER;
+  contents: Array<{
+    type: "TEXT";
+    text: string;
+  }>;
+}
+```
+
+**AI 消息**：
+```typescript
+interface AiMessage {
+  type: MessageType.AI;
+  text: string;
+  toolExecutionRequests?: Array<{
+    id: string;
+    toolName: string;
+    parameters: any;
+  }>;
+}
+```
+
+**系统消息**：
+```typescript
+interface SystemMessage {
+  type: MessageType.SYSTEM;
+  text: string;
+}
+```
+
+**工具执行结果消息**：
+```typescript
+interface ToolExecutionResultMessage {
+  type: MessageType.TOOL_EXECUTION_RESULT;
+  id: string;
+  toolName: string;
+  text: string;
+}
+```
+
+### 3.3 ConversationMeta（对话轮次元数据）
+
+存储在 `conversation_meta.jsonl` 文件中，每行一条记录（JSONL 格式）。
+
+```typescript
+interface ConversationMeta {
+  turnId: number;           // 对话轮次 ID
+  timestamp: string;        // 时间戳（ISO 8601）
+  usage?: {
+    inputTokens?: number;
+    outputTokens?: number;
+    totalTokens?: number;
+  };
+  model?: string;           // 使用的模型
+  duration?: number;        // 耗时（毫秒）
+}
+```
+
+**示例**：
+```jsonl
+{"turnId":1,"timestamp":"2023-12-26T10:30:15.000Z","usage":{"inputTokens":120,"outputTokens":350,"totalTokens":470},"model":"gpt-4","duration":2500}
+{"turnId":2,"timestamp":"2023-12-26T10:32:30.000Z","usage":{"inputTokens":200,"outputTokens":450,"totalTokens":650},"model":"gpt-4","duration":3200}
+```
+
+---
+
+## 4. 核心功能实现
+
+### 4.1 任务创建
+
+**方法**：`createTask(projectPath: string, taskName: string): Promise<TaskMeta>`
+
+**流程**：
+1. 生成唯一的任务 ID
+2. 创建任务元数据对象
+3. 创建任务目录
+4. 保存 `meta.json`
+5. 初始化空的 `conversation.json`
+6. 设置为当前任务
+
+**代码位置**：`chatHistoryManager.ts:114-146`
+
+```typescript
+public async createTask(projectPath: string, taskName: string): Promise<TaskMeta> {
+  const taskId = this.generateTaskId();
+  const now = new Date().toISOString();
+
+  const meta: TaskMeta = {
+    taskId,
+    taskName,
+    projectPath,
+    createdAt: now,
+    updatedAt: now,
+    stats: {
+      credits: 0,
+      totalTokens: 0,
+      inputTokens: 0,
+      outputTokens: 0
+    }
+  };
+
+  this.currentTaskId = taskId;
+  this.currentProjectPath = projectPath;
+
+  // 创建任务目录
+  const taskDir = this.getTaskDir(projectPath, taskId);
+  await this.ensureTaskDir(taskDir);
+
+  // 保存 meta.json
+  await this.saveTaskMeta(meta);
+
+  // 初始化空的 conversation.json
+  await this.saveConversation([]);
+
+  return meta;
+}
+```
+
+### 4.2 消息保存
+
+系统提供了四种消息保存方法：
+
+#### 4.2.1 添加用户消息
+
+**方法**：`addUserMessage(text: string): Promise<void>`
+
+**代码位置**：`chatHistoryManager.ts:285-299`
+
+```typescript
+public async addUserMessage(text: string): Promise<void> {
+  await this.ensureCurrentTask();
+  const messages = await this.loadConversation();
+
+  const userMessage: UserMessage = {
+    type: MessageType.USER,
+    contents: [{ type: "TEXT", text }]
+  };
+
+  messages.push(userMessage);
+  await this.saveConversation(messages);
+
+  // 更新任务元数据
+  await this.updateTaskTimestamp();
+}
+```
+
+#### 4.2.2 添加 AI 消息
+
+**方法**：`addAiMessage(text: string, toolRequests?: any[]): Promise<void>`
+
+**代码位置**：`chatHistoryManager.ts:304-319`
+
+#### 4.2.3 添加系统消息
+
+**方法**：`addSystemMessage(text: string): Promise<void>`
+
+**代码位置**：`chatHistoryManager.ts:324-335`
+
+#### 4.2.4 添加工具执行结果
+
+**方法**：`addToolExecutionResult(id: string, toolName: string, result: string): Promise<void>`
+
+**代码位置**：`chatHistoryManager.ts:340-353`
+
+### 4.3 对话元数据记录
+
+**方法**：`recordTurnMeta(turnId, usage?, model?, duration?): Promise<void>`
+
+**功能**：记录每轮对话的元数据，包括 Token 使用量、模型信息、耗时等。
+
+**代码位置**：`chatHistoryManager.ts:358-378`
+
+```typescript
+public async recordTurnMeta(
+  turnId: number,
+  usage?: { inputTokens?: number; outputTokens?: number; totalTokens?: number },
+  model?: string,
+  duration?: number
+): Promise<void> {
+  const meta: ConversationMeta = {
+    turnId,
+    timestamp: new Date().toISOString(),
+    usage,
+    model,
+    duration
+  };
+
+  await this.appendConversationMeta(meta);
+
+  // 更新任务统计
+  if (usage) {
+    await this.updateTaskStats(usage);
+  }
+}
+```
+
+### 4.4 会话历史查询
+
+**方法**：`getConversationHistoryList(projectPath, offset, limit): Promise<{items, total, hasMore}>`
+
+**功能**：分页查询项目的会话历史列表。
+
+**参数**：
+- `projectPath`：项目路径
+- `offset`：偏移量（从第几条开始，默认 0）
+- `limit`：每页数量（默认 10）
+
+**返回值**：
+```typescript
+{
+  items: Array<{
+    id: string;        // 任务 ID
+    title: string;     // 会话标题（第一句用户消息）
+    timestamp: string; // 创建时间
+  }>;
+  total: number;       // 总数
+  hasMore: boolean;    // 是否还有更多
+}
+```
+
+**代码位置**：`chatHistoryManager.ts:525-590`
+
+**实现逻辑**：
+1. 获取项目的所有任务列表（按更新时间倒序）
+2. 根据 offset 和 limit 进行分页
+3. 读取每个任务的 `conversation.json`
+4. 提取第一条用户消息作为标题（截取前 50 个字符）
+5. 返回分页结果
+
+---
+
+## 5. 前端集成
+
+### 5.1 会话历史栏组件
+
+**文件**：`conversationHistoryBar.ts`
+
+**组件结构**：
+- 下拉按钮：显示 "Past Conversations"
+- 下拉菜单：显示会话历史列表
+- 新建按钮：创建新会话
+
+**关键功能**：
+
+#### 5.1.1 加载会话历史
+
+```javascript
+function loadMoreHistory() {
+  if (isLoadingHistory || (currentOffset > 0 && !hasMoreHistory)) {
+    return;
+  }
+
+  // 检查是否已达到最大数量（100 条）
+  if (currentOffset >= MAX_HISTORY_ITEMS) {
+    return;
+  }
+
+  isLoadingHistory = true;
+  vscode.postMessage({
+    command: 'loadConversationHistory',
+    offset: currentOffset,
+    limit: HISTORY_PAGE_SIZE
+  });
+}
+```
+
+#### 5.1.2 渲染会话列表
+
+```javascript
+function renderConversationHistory(data) {
+  isLoadingHistory = false;
+
+  // 追加新数据
+  conversationHistory = conversationHistory.concat(data.items);
+  totalHistory = data.total;
+  hasMoreHistory = data.hasMore;
+  currentOffset += data.items.length;
+
+  // 渲染所有历史记录
+  historyList.innerHTML = conversationHistory.map(item => `
+    <div class="history-item" onclick="selectConversation('${item.id}')">
+      <div class="history-item-title">${item.title || '未命名会话'}</div>
+      <div class="history-item-time">${formatTime(item.timestamp)}</div>
+    </div>
+  `).join('');
+
+  // 如果还有更多数据，添加"加载更多"提示
+  if (hasMoreHistory && currentOffset < MAX_HISTORY_ITEMS) {
+    historyList.innerHTML += `
+      <div class="history-load-more">
+        <span>滚动加载更多...</span>
+      </div>
+    `;
+  }
+}
+```
+
+#### 5.1.3 滚动加载
+
+```javascript
+historyDropdownMenu.addEventListener('scroll', () => {
+  const menu = historyDropdownMenu;
+  const scrollTop = menu.scrollTop;
+  const scrollHeight = menu.scrollHeight;
+  const clientHeight = menu.clientHeight;
+
+  // 当滚动到距离底部 50px 时，加载更多
+  if (scrollHeight - scrollTop - clientHeight < 50) {
+    loadMoreHistory();
+  }
+});
+```
+
+#### 5.1.4 时间格式化
+
+```javascript
+function formatTime(timestamp) {
+  const date = new Date(timestamp);
+  const now = new Date();
+  const diff = now - date;
+
+  if (diff < 60000) return '刚刚';
+  if (diff < 3600000) return Math.floor(diff / 60000) + '分钟前';
+  if (diff < 86400000) return Math.floor(diff / 3600000) + '小时前';
+  if (diff < 604800000) return Math.floor(diff / 86400000) + '天前';
+
+  // 超过7天显示具体日期
+  return date.toLocaleDateString('zh-CN', {
+    year: 'numeric',
+    month: '2-digit',
+    day: '2-digit'
+  });
+}
+```
+
+### 5.2 后端消息处理
+
+**文件**：`ICHelperPanel.ts`
+
+**消息处理流程**：
+
+```typescript
+case "loadConversationHistory":
+  // 加载会话历史（支持分页）
+  loadConversationHistory(panel, message.offset || 0, message.limit || 10);
+  break;
+
+case "selectConversation":
+  // 选择会话（暂未实现）
+  break;
+
+case "createNewConversation":
+  // 创建新会话 - 在当前编辑器组中打开新标签页
+  showICHelperPanel(context, panel.viewColumn);
+  break;
+```
+
+**加载会话历史实现**：
+
+```typescript
+async function loadConversationHistory(
+  panel: vscode.WebviewPanel,
+  offset: number = 0,
+  limit: number = 10
+) {

+    });
+  }
+}
+```
+
+---
+
+## 6. 使用示例
+
+### 6.1 创建新任务并保存对话
+
+```typescript
+const historyManager = ChatHistoryManager.getInstance();
+
+// 创建新任务
+const task = await historyManager.createTask(
+  'C:\\Users\\admin\\Documents\\Project',
+  '实现计数器功能'
+);
+
+// 添加用户消息
+await historyManager.addUserMessage('请帮我生成一个4位计数器');
+
+// 添加 AI 消息
+await historyManager.addAiMessage(
+  '好的，我来帮你生成一个4位计数器...',
+  [{ id: '1', toolName: 'generateCode', parameters: {} }]
+);
+
+// 添加工具执行结果
+await historyManager.addToolExecutionResult(
+  '1',
+  'generateCode',
+  '代码生成成功'
+);
+
+// 记录对话元数据
+await historyManager.recordTurnMeta(
+  1,
+  { inputTokens: 120, outputTokens: 350, totalTokens: 470 },
+  'gpt-4',
+  2500
+);
+```
+
+### 6.2 查询会话历史
+
+```typescript
+const historyManager = ChatHistoryManager.getInstance();
+
+// 获取第一页（前10条）
+const page1 = await historyManager.getConversationHistoryList(
+  'C:\\Users\\admin\\Documents\\Project',
+  0,
+  10
+);
+
+console.log('总数:', page1.total);
+console.log('是否还有更多:', page1.hasMore);
+console.log('会话列表:', page1.items);
+
+// 获取第二页（第11-20条）
+const page2 = await historyManager.getConversationHistoryList(
+  'C:\\Users\\admin\\Documents\\Project',
+  10,
+  10
+);
+```
+
+### 6.3 切换任务
+
+```typescript
+const historyManager = ChatHistoryManager.getInstance();
+
+// 切换到指定任务
+const success = await historyManager.switchTask(
+  'C:\\Users\\admin\\Documents\\Project',
+  'task_20231226_a3f9k2'
+);
+
+if (success) {
+  // 获取当前任务会话
+  const session = await historyManager.getCurrentTaskSession();
+  console.log('任务元数据:', session.meta);
+  console.log('对话历史:', session.messages);
+  console.log('对话元数据:', session.conversationMeta);
+}
+```
+
+---
+
+## 7. 性能优化
+
+### 7.1 分页加载
+
+- 前端默认每页加载 10 条记录
+- 最多显示 100 条历史记录
+- 滚动到底部时自动加载下一页
+
+### 7.2 懒加载
+
+- 只在打开下拉菜单时才加载会话历史
+- 避免不必要的文件读取操作
+
+### 7.3 缓存机制
+
+- 前端缓存已加载的会话列表
+- 避免重复请求相同数据
+
+### 7.4 文件格式优化
+
+- 使用 JSONL 格式存储对话元数据，支持追加写入
+- 避免频繁读写整个文件
+
+---
+
+## 8. 错误处理
+
+### 8.1 目录不存在
+
+系统会自动创建不存在的目录：
+
+```typescript
+private async ensureTaskDir(taskDir: string): Promise<void> {
+  try {
+    const uri = vscode.Uri.file(taskDir);
+    try {
+      await vscode.workspace.fs.stat(uri);
+    } catch {
+      // 目录不存在，创建它
+      await vscode.workspace.fs.createDirectory(uri);
+      console.log(`创建任务目录: ${taskDir}`);
+    }
+  } catch (error) {
+    console.error("创建任务目录失败:", error);
+    throw error;
+  }
+}
+```
+
+### 8.2 文件读取失败
+
+读取失败时返回默认值：
+
+```typescript
+private async loadConversation(): Promise<ChatMessage[]> {
+  try {
+    const uri = vscode.Uri.file(conversationPath);
+    const content = await vscode.workspace.fs.readFile(uri);
+    const data = Buffer.from(content).toString('utf-8');
+    return JSON.parse(data);
+  } catch (error) {
+    // 文件不存在或读取失败，返回空数组
+    return [];
+  }
+}
+```
+
+### 8.3 无工作区处理
+
+没有打开工作区时，自动创建默认任务：
+
+```typescript
+private async ensureCurrentTask(): Promise<void> {
+  if (!this.currentTaskId || !this.currentProjectPath) {
+    const workspacePath = vscode.workspace.workspaceFolders?.[0]?.uri.fsPath;
+    if (workspacePath) {
+      await this.createTask(workspacePath, "默认任务");
+    } else {
+      throw new Error("没有打开的工作区，无法创建任务");
+    }
+  }
+}
+```
+
+---
+
+## 9. 未来扩展
+
+### 9.1 会话切换功能
+
+目前 `selectConversation` 功能暂未实现，未来可以支持：
+- 点击历史会话，加载该会话的完整对话历史
+- 在新标签页中打开历史会话
+- 继续历史会话的对话
+
+### 9.2 会话搜索
+
+- 支持按关键词搜索会话
+- 支持按时间范围筛选
+- 支持按 Token 使用量排序
+
+### 9.3 会话导出
+
+- 导出为 Markdown 格式
+- 导出为 JSON 格式
+- 导出为 PDF 格式
+
+### 9.4 会话统计
+
+- 显示总对话轮次
+- 显示总 Token 使用量
+- 显示平均响应时间
+
+### 9.5 云端同步
+
+- 支持将会话数据同步到云端
+- 支持多设备访问
+- 支持团队协作
+
+---
+
+## 10. 总结
+
+IC Coder 的会话存储系统采用文件系统存储方案，具有以下优势：
+
+1. **简单可靠**：无需额外的数据库依赖
+2. **易于备份**：直接复制文件即可备份
+3. **跨平台**：支持 Windows、macOS、Linux
+4. **可扩展**：易于添加新的数据字段
+5. **高性能**：分页加载，避免一次性加载大量数据
+
+系统已经实现了核心的会话管理功能，包括任务创建、消息保存、历史查询等，为用户提供了完整的会话历史管理体验。
