+# AskUserQuestion 多选支持 - API 设计文档
+
+## 问题描述
+
+当前 AI 询问用户问题时存在以下问题：
+1. 后端返回的选项不准确
+2. 多个问题只给几个选项
+3. 不支持多选方式
+
+## 需求
+
+实现一个问题对应多个选项，支持多选的方式。
+
+## 数据结构设计
+
+### 后端返回格式
+
+后端通过 SSE 的 `ask_user` 事件返回以下格式：
+
+```json
+{
+  "askId": "ask_1234567890",
+  "questions": [
+    {
+      "question": "请确认 SPI 控制器的配置需求：工作模式？",
+      "options": [
+        "Master/8位/模式0/固定分频/需要CS",
+        "Master/可配置位宽/可配置模式/需要CS",
+        "Slave模式"
+      ],
+      "multiSelect": false
+    },
+    {
+      "question": "数据位宽？",
+      "options": [
+        "8位 还是其他？"
+      ],
+      "multiSelect": false
+    },
+    {
+      "question": "时钟极性和相位？",
+      "options": [
+        "CPOL=0/CPHA=0 (模式0) 还是其他模式？"
+      ],
+      "multiSelect": false
+    },
+    {
+      "question": "时钟分频？",
+      "options": [
+        "需要可配置的分频比吗？"
+      ],
+      "multiSelect": false
+    },
+    {
+      "question": "是否需要芯片选信号 (CS) 控制？",
+      "options": [
+        "是",
+        "否"
+      ],
+      "multiSelect": false
+    }
+  ]
+}
+```
+
+### 前端数据结构
+
+#### 1. API 类型定义 (`src/types/api.ts`)
+
+```typescript
+/** ask_user 事件数据 */
+export interface AskUserEvent {
+  askId: string;
+  questions: QuestionItem[];
+}
+
+/** 单个问题项 */
+export interface QuestionItem {
+  question: string;
+  options: string[];
+  multiSelect?: boolean; // 是否支持多选，默认 false
+}
+```
+
+#### 2. MessageSegment 类型 (`src/services/dialogService.ts`)
+
+```typescript
+export interface MessageSegment {
+  type: "text" | "tool" | "question" | "agent" | "plan" | "progress";
+  // ... 其他字段
+  askId?: string;
+  questions?: QuestionItem[]; // 改为问题数组
+}
+```
+
+#### 3. 用户回答格式 (`src/types/api.ts`)
+
+```typescript
+export interface AnswerRequest {
+  taskId: string;
+  askId: string;
+  answers: {
+    [questionIndex: number]: string[]; // 每个问题的答案数组（支持多选）
+  };
+}
+```
+
+## 前端实现要点
+
+### 1. 显示多个问题
+
+```typescript
+// 遍历 questions 数组，为每个问题生成 UI
+segment.questions?.forEach((q, index) => {
+  // 显示问题标题
+  // 显示选项（单选或多选）
+  // 收集答案
+});
+```
+
+### 2. 多选支持
+
+```typescript
+if (q.multiSelect) {
+  // 渲染复选框
+  // 允许选择多个选项
+} else {
+  // 渲染单选按钮
+  // 只允许选择一个选项
+}
+```
+
+### 3. 提交答案
+
+```typescript
+const answers = {
+  0: ["Master/8位/模式0/固定分频/需要CS"], // 第1个问题的答案
+  1: ["8位 还是其他？"],                    // 第2个问题的答案
+  2: ["CPOL=0/CPHA=0 (模式0) 还是其他模式？"], // 第3个问题的答案
+  // ...
+};
+
+vscode.postMessage({
+  command: 'userAnswer',
+  askId: 'ask_1234567890',
+  answers: answers
+});
+```
+
+## 后端需要做的修改
+
+### 1. 修改 AskUserQuestion 工具的返回格式
+
+从：
+```json
+{
+  "askId": "xxx",
+  "question": "单个问题",
+  "options": ["选项1", "选项2"]
+}
+```
+
+改为：
+```json
+{
+  "askId": "xxx",
+  "questions": [
+    {
+      "question": "问题1",
+      "options": ["选项1", "选项2"],
+      "multiSelect": false
+    },
+    {
+      "question": "问题2",
+      "options": ["选项A", "选项B", "选项C"],
+      "multiSelect": true
+    }
+  ]
+}
+```
+
+### 2. 接收答案的格式
+
+从：
+```json
+{
+  "taskId": "xxx",
+  "askId": "xxx",
+  "selected": ["选项1"],
+  "customInput": "自定义输入"
+}
+```
+
+改为：
+```json
+{
+  "taskId": "xxx",
+  "askId": "xxx",
+  "answers": {
+    "0": ["选项1"],           // 第1个问题的答案
+    "1": ["选项A", "选项B"]   // 第2个问题的答案（多选）
+  }
+}
+```
+
+## 示例场景
+
+### 场景：SPI 控制器配置
+
+**后端发送：**
+```json
+{
+  "askId": "ask_spi_config",
+  "questions": [
+    {
+      "question": "工作模式？",
+      "options": [
+        "Master/8位/模式0/固定分频/需要CS",
+        "Master/可配置位宽/可配置模式/需要CS",
+        "Slave模式"
+      ],
+      "multiSelect": false
+    },
+    {
+      "question": "需要哪些功能？",
+      "options": [
+        "可配置时钟分频",
+        "可配置数据位宽",
+        "支持多个CS",
+        "DMA支持"
+      ],
+      "multiSelect": true
+    }
+  ]
+}
+```
+
+**用户选择：**
+- 问题1：选择 "Master/8位/模式0/固定分频/需要CS"
+- 问题2：选择 "可配置时钟分频" 和 "可配置数据位宽"
+
+**前端提交：**
+```json
+{
+  "taskId": "task_xxx",
+  "askId": "ask_spi_config",
+  "answers": {
+    "0": ["Master/8位/模式0/固定分频/需要CS"],
+    "1": ["可配置时钟分频", "可配置数据位宽"]
+  }
+}
+```
+
+## 总结
+
+这个设计方案：
+1. ✅ 支持多个问题
+2. ✅ 每个问题有多个选项
+3. ✅ 支持单选和多选
+4. ✅ 数据结构清晰，易于扩展
+5. ✅ 向后兼容（可以只有一个问题）

+
+---
+
+## 1. Extension 生命周期 ⭐⭐⭐
+
+### 1.1 核心函数 🔥必考
+
+```typescript
+// extension.ts
+import * as vscode from 'vscode';
+
+// 插件激活时调用（只调用一次）
+export function activate(context: vscode.ExtensionContext) {
+    console.log('Extension is now active!');
+
+    // 注册命令、视图、事件监听等
+    // 使用 context.subscriptions 管理资源
+}
+
+// 插件停用时调用（清理资源）
+export function deactivate() {
+    console.log('Extension is deactivated');
+    // 清理资源、关闭连接等
+}
+```
+
+### 1.2 ExtensionContext 重要属性 🔥必考
+
+```typescript
+interface ExtensionContext {
+    // 插件订阅管理（自动清理）
+    subscriptions: { dispose(): any }[];
+
+    // 工作区存储路径
+    storageUri: vscode.Uri | undefined;
+    globalStorageUri: vscode.Uri;
+
+    // 插件路径
+    extensionUri: vscode.Uri;
+    extensionPath: string;
+
+    // 状态存储
+    workspaceState: Memento;  // 工作区级别
+    globalState: Memento;     // 全局级别
+    secrets: SecretStorage;   // 敏感信息存储
+
+    // 环境变量
+    environmentVariableCollection: EnvironmentVariableCollection;
+}
+```
+
+### 1.3 资源管理最佳实践 🔥必考
+
+```typescript
+export function activate(context: vscode.ExtensionContext) {
+    // ✅ 推荐：使用 context.subscriptions 自动管理
+    context.subscriptions.push(
+        vscode.commands.registerCommand('extension.command', () => {})
+    );
+
+    // ❌ 不推荐：手动管理容易忘记清理
+    const disposable = vscode.commands.registerCommand('extension.command', () => {});
+    // 需要在 deactivate 中手动调用 disposable.dispose()
+}
+```
+
+---
+
+## 2. 激活事件 (Activation Events) ⭐⭐
+
+### 2.1 常用激活事件 📌重要
+
+```json
+// package.json
+{
+    "activationEvents": [
+        // 启动时激活
+        "onStartupFinished",
+
+        // 执行命令时激活
+        "onCommand:extension.helloWorld",
+
+        // 打开特定语言文件时激活
+        "onLanguage:javascript",
+        "onLanguage:verilog",
+
+        // 打开特定文件类型时激活
+        "onFileSystem:sftp",
+
+        // 打开特定视图时激活
+        "onView:myCustomView",
+
+        // 调试时激活
+        "onDebug",
+
+        // 打开特定 URI 时激活
+        "onUri",
+
+        // Webview 恢复时激活
+        "onWebviewPanel:myWebview",
+
+        // 任务执行时激活
+        "onTaskType:npm"
+    ]
+}
+```
+
+### 2.2 延迟激活策略 🔥必考
+
+```typescript
+// ✅ 推荐：使用 onStartupFinished 延迟激活
+"activationEvents": ["onStartupFinished"]
+
+// ❌ 不推荐：使用 * 会拖慢启动速度
+"activationEvents": ["*"]
+```
+
+---
+
+## 3. 命令系统 (Commands)
+
+### 3.1 注册命令
+
+```typescript
+// 注册简单命令
+const disposable = vscode.commands.registerCommand(
+    'extension.helloWorld',
+    () => {
+        vscode.window.showInformationMessage('Hello World!');
+    }
+);
+context.subscriptions.push(disposable);
+
+// 注册带参数的命令
+vscode.commands.registerCommand(
+    'extension.openFile',
+    (filePath: string) => {
+        vscode.workspace.openTextDocument(filePath).then(doc => {
+            vscode.window.showTextDocument(doc);
+        });
+    }
+);
+```
+
+### 3.2 执行命令
+
+```typescript
+// 执行内置命令
+await vscode.commands.executeCommand('workbench.action.files.save');
+
+// 执行自定义命令
+await vscode.commands.executeCommand('extension.openFile', '/path/to/file');
+
+// 获取所有可用命令
+const commands = await vscode.commands.getCommands();
+```
+
+### 3.3 常用内置命令
+
+```typescript
+// 文件操作
+'workbench.action.files.save'
+'workbench.action.files.saveAll'
+'workbench.action.closeActiveEditor'
+
+// 编辑器操作
+'editor.action.formatDocument'
+'editor.action.commentLine'
+'editor.action.selectAll'
+
+// 窗口操作
+'workbench.action.toggleSidebarVisibility'
+'workbench.action.terminal.new'
+'workbench.action.quickOpen'
+
+// Git 操作
+'git.commit'
+'git.push'
+'git.pull'
+```
+
+---
+
+## 4. Webview API ⭐⭐⭐⭐⭐ **面试重点**
+
+### 4.1 创建 Webview Panel 🔥必考
+
+```typescript
+const panel = vscode.window.createWebviewPanel(
+    'myWebview',              // viewType（唯一标识）
+    'My Webview',             // 标题
+    vscode.ViewColumn.One,    // 显示位置
+    {
+        enableScripts: true,  // 启用 JavaScript
+        retainContextWhenHidden: true,  // 隐藏时保留状态
+        localResourceRoots: [  // 允许访问的本地资源路径
+            vscode.Uri.joinPath(context.extensionUri, 'media')
+        ]
+    }
+);
+```
+
+### 4.2 设置 Webview 内容
+
+```typescript
+panel.webview.html = getWebviewContent();
+
+function getWebviewContent() {
+    return `<!DOCTYPE html>
+    <html lang="en">
+    <head>
+        <meta charset="UTF-8">
+        <meta name="viewport" content="width=device-width, initial-scale=1.0">
+        <title>My Webview</title>
+    </head>
+    <body>
+        <h1>Hello from Webview!</h1>
+        <button onclick="sendMessage()">Send Message</button>
+
+        <script>
+            const vscode = acquireVsCodeApi();
+
+            function sendMessage() {
+                vscode.postMessage({
+                    command: 'alert',
+                    text: 'Hello from Webview!'
+                });
+            }
+
+            // 接收来自 Extension 的消息
+            window.addEventListener('message', event => {
+                const message = event.data;
+                console.log('Received:', message);
+            });
+        </script>
+    </body>
+    </html>`;
+}
+```
+
+### 4.3 Webview 消息通信 🔥必考（项目核心）
+
+```typescript
+// Extension → Webview
+panel.webview.postMessage({
+    command: 'update',
+    data: 'some data'
+});
+
+// Webview → Extension
+panel.webview.onDidReceiveMessage(
+    message => {
+        switch (message.command) {
+            case 'alert':
+                vscode.window.showInformationMessage(message.text);
+                break;
+            case 'getData':
+                // 处理数据请求
+                panel.webview.postMessage({
+                    command: 'dataResponse',
+                    data: fetchData()
+                });
+                break;
+        }
+    },
+    undefined,
+    context.subscriptions
+);
+```
+
+### 4.4 Webview 生命周期管理 📌重要
+
+```typescript
+// 监听 Webview 关闭事件
+panel.onDidDispose(
+    () => {
+        // 清理资源
+        console.log('Webview disposed');
+    },
+    null,
+    context.subscriptions
+);
+
+// 监听 Webview 可见性变化
+panel.onDidChangeViewState(
+    e => {
+        if (e.webviewPanel.visible) {
+            console.log('Webview is now visible');
+        }
+    },
+    null,
+    context.subscriptions
+);
+```
+
+### 4.5 加载本地资源 📌重要
+
+```typescript
+// 获取本地资源 URI
+const scriptUri = panel.webview.asWebviewUri(
+    vscode.Uri.joinPath(context.extensionUri, 'media', 'script.js')
+);
+
+const styleUri = panel.webview.asWebviewUri(
+    vscode.Uri.joinPath(context.extensionUri, 'media', 'style.css')
+);
+
+// 在 HTML 中使用
+const html = `
+    <link href="${styleUri}" rel="stylesheet">
+    <script src="${scriptUri}"></script>
+`;
+```
+
+### 4.6 Webview 状态持久化 📌重要
+
+```typescript
+// Webview 中保存状态
+const vscode = acquireVsCodeApi();
+const state = vscode.getState() || { count: 0 };
+
+// 更新状态
+state.count++;
+vscode.setState(state);
+
+// Extension 中序列化状态
+panel.webview.options = {
+    enableScripts: true,
+    retainContextWhenHidden: true
+};
+
+// 恢复 Webview
+vscode.window.registerWebviewPanelSerializer('myWebview', {
+    async deserializeWebviewPanel(webviewPanel, state) {
+        webviewPanel.webview.html = getWebviewContent();
+        // 恢复状态
+        webviewPanel.webview.postMessage({ command: 'restore', state });
+    }
+});
+```
+
+---
+
+## 5. TreeView 和自定义视图
+
+### 5.1 创建 TreeView Provider
+
+```typescript
+class MyTreeDataProvider implements vscode.TreeDataProvider<TreeItem> {
+    private _onDidChangeTreeData = new vscode.EventEmitter<TreeItem | undefined>();
+    readonly onDidChangeTreeData = this._onDidChangeTreeData.event;
+
+    refresh(): void {
+        this._onDidChangeTreeData.fire(undefined);
+    }
+
+    getTreeItem(element: TreeItem): vscode.TreeItem {
+        return element;
+    }
+
+    getChildren(element?: TreeItem): Thenable<TreeItem[]> {
+        if (!element) {
+            // 返回根节点
+            return Promise.resolve([
+                new TreeItem('Item 1', vscode.TreeItemCollapsibleState.None),
+                new TreeItem('Item 2', vscode.TreeItemCollapsibleState.Collapsed)
+            ]);
+        }
+        // 返回子节点
+        return Promise.resolve([]);
+    }
+}
+
+class TreeItem extends vscode.TreeItem {
+    constructor(
+        public readonly label: string,
+        public readonly collapsibleState: vscode.TreeItemCollapsibleState
+    ) {
+        super(label, collapsibleState);
+        this.tooltip = `Tooltip for ${label}`;
+        this.command = {
+            command: 'extension.itemClicked',
+            title: 'Click Item',
+            arguments: [this]
+        };
+    }
+}
+```
+
+### 5.2 注册 TreeView
+
+```typescript
+const treeDataProvider = new MyTreeDataProvider();
+const treeView = vscode.window.createTreeView('myTreeView', {
+    treeDataProvider,
+    showCollapseAll: true
+});
+
+context.subscriptions.push(treeView);
+
+// 刷新视图
+treeDataProvider.refresh();
+```
+
+### 5.3 WebviewView Provider（侧边栏 Webview）
+
+```typescript
+class MyWebviewViewProvider implements vscode.WebviewViewProvider {
+    resolveWebviewView(
+        webviewView: vscode.WebviewView,
+        context: vscode.WebviewViewResolveContext,
+        token: vscode.CancellationToken
+    ) {
+        webviewView.webview.options = {
+            enableScripts: true
+        };
+
+        webviewView.webview.html = getWebviewContent();
+
+        webviewView.webview.onDidReceiveMessage(message => {
+            // 处理消息
+        });
+    }
+}
+
+// 注册
+vscode.window.registerWebviewViewProvider(
+    'myWebviewView',
+    new MyWebviewViewProvider()
+);
+```
+
+---
+
+## 6. 文件系统操作 ⭐⭐⭐
+
+### 6.1 读取文件 📌重要
+
+```typescript
+// 读取文本文件
+const uri = vscode.Uri.file('/path/to/file.txt');
+const content = await vscode.workspace.fs.readFile(uri);
+const text = Buffer.from(content).toString('utf8');
+
+// 使用 TextDocument API
+const document = await vscode.workspace.openTextDocument(uri);
+const text = document.getText();
+```
+
+### 6.2 写入文件
+
+```typescript
+// 写入文件
+const uri = vscode.Uri.file('/path/to/file.txt');
+const content = Buffer.from('Hello World', 'utf8');
+await vscode.workspace.fs.writeFile(uri, content);
+
+// 使用 WorkspaceEdit
+const edit = new vscode.WorkspaceEdit();
+edit.createFile(uri, { overwrite: true });
+edit.insert(uri, new vscode.Position(0, 0), 'Hello World');
+await vscode.workspace.applyEdit(edit);
+```
+
+### 6.3 文件监听
+
+```typescript
+// 监听文件变化
+const watcher = vscode.workspace.createFileSystemWatcher('**/*.js');
+
+watcher.onDidCreate(uri => {
+    console.log('File created:', uri.fsPath);
+});
+
+watcher.onDidChange(uri => {
+    console.log('File changed:', uri.fsPath);
+});
+
+watcher.onDidDelete(uri => {
+    console.log('File deleted:', uri.fsPath);
+});
+
+context.subscriptions.push(watcher);
+```
+
+### 6.4 工作区操作
+
+```typescript
+// 获取工作区文件夹
+const workspaceFolders = vscode.workspace.workspaceFolders;
+if (workspaceFolders) {
+    const rootPath = workspaceFolders[0].uri.fsPath;
+}
+
+// 查找文件
+const files = await vscode.workspace.findFiles(
+    '**/*.ts',      // include pattern
+    '**/node_modules/**'  // exclude pattern
+);
+
+// 打开文件
+const document = await vscode.workspace.openTextDocument(uri);
+await vscode.window.showTextDocument(document);
+```
+
+---
+
+## 7. 配置和存储 ⭐⭐⭐⭐ **面试重点**
+
+### 7.1 读取配置 📌重要
+
+```typescript
+// 读取配置
+const config = vscode.workspace.getConfiguration('myExtension');
+const value = config.get<string>('settingName', 'defaultValue');
+
+// 监听配置变化
+vscode.workspace.onDidChangeConfiguration(e => {
+    if (e.affectsConfiguration('myExtension.settingName')) {
+        console.log('Configuration changed');
+    }
+});
+```
+
+### 7.2 更新配置
+
+```typescript
+const config = vscode.workspace.getConfiguration('myExtension');
+
+// 更新用户配置（全局）
+await config.update('settingName', 'newValue', vscode.ConfigurationTarget.Global);
+
+// 更新工作区配置
+await config.update('settingName', 'newValue', vscode.ConfigurationTarget.Workspace);
+```
+
+### 7.3 状态存储 🔥必考
+
+```typescript
+// 工作区状态（仅当前工作区）
+await context.workspaceState.update('key', 'value');
+const value = context.workspaceState.get('key');
+
+// 全局状态（跨工作区）
+await context.globalState.update('key', 'value');
+const value = context.globalState.get('key');
+
+// 存储对象
+await context.globalState.update('userData', { name: 'John', age: 30 });
+```
+
+### 7.4 敏感信息存储 🔥必考（Token 管理）
+
+```typescript
+// 存储密码、Token 等敏感信息
+await context.secrets.store('apiToken', 'secret-token-value');
+
+// 读取
+const token = await context.secrets.get('apiToken');
+
+// 删除
+await context.secrets.delete('apiToken');
+
+// 监听变化
+context.secrets.onDidChange(e => {
+    console.log('Secret changed:', e.key);
+});
+```
+
+---
+
+## 8. 消息通知
+
+### 8.1 信息提示
+
+```typescript
+// 普通信息
+vscode.window.showInformationMessage('Operation completed!');
+
+// 警告
+vscode.window.showWarningMessage('This action may cause issues');
+
+// 错误
+vscode.window.showErrorMessage('Operation failed!');
+```
+
+### 8.2 带按钮的提示
+
+```typescript
+const result = await vscode.window.showInformationMessage(
+    'Do you want to continue?',
+    'Yes',
+    'No',
+    'Cancel'
+);
+
+if (result === 'Yes') {
+    // 用户点击了 Yes
+}
+```
+
+### 8.3 输入框
+
+```typescript
+// 简单输入
+const input = await vscode.window.showInputBox({
+    prompt: 'Enter your name',
+    placeHolder: 'John Doe',
+    validateInput: (value) => {
+        return value.length < 3 ? 'Name too short' : null;
+    }
+});
+
+// 快速选择
+const selected = await vscode.window.showQuickPick(
+    ['Option 1', 'Option 2', 'Option 3'],
+    {
+        placeHolder: 'Select an option',
+        canPickMany: false
+    }
+);
+```
+
+### 8.4 进度提示
+
+```typescript
+await vscode.window.withProgress(
+    {
+        location: vscode.ProgressLocation.Notification,
+        title: 'Processing...',
+        cancellable: true
+    },
+    async (progress, token) => {
+        token.onCancellationRequested(() => {
+            console.log('User canceled');
+        });
+
+        progress.report({ increment: 0, message: 'Starting...' });
+        await doWork1();
+
+        progress.report({ increment: 50, message: 'Half done...' });
+        await doWork2();
+
+        progress.report({ increment: 100, message: 'Complete!' });
+    }
+);
+```
+
+---
+
+## 9. 语言特性支持
+
+### 9.1 代码补全
+
+```typescript
+const provider = vscode.languages.registerCompletionItemProvider(
+    'javascript',
+    {
+        provideCompletionItems(document, position) {
+            const item = new vscode.CompletionItem('myFunction');
+            item.kind = vscode.CompletionItemKind.Function;
+            item.detail = 'My custom function';
+            item.documentation = 'This is a custom function';
+            item.insertText = new vscode.SnippetString('myFunction($1)$0');
+
+            return [item];
+        }
+    },
+    '.'  // 触发字符
+);
+
+context.subscriptions.push(provider);
+```
+
+### 9.2 悬停提示
+
+```typescript
+const provider = vscode.languages.registerHoverProvider('javascript', {
+    provideHover(document, position) {
+        const range = document.getWordRangeAtPosition(position);
+        const word = document.getText(range);
+
+        return new vscode.Hover([
+            `**${word}**`,
+            'This is a hover tooltip'
+        ]);
+    }
+});
+```
+
+### 9.3 诊断（错误提示）
+
+```typescript
+const diagnosticCollection = vscode.languages.createDiagnosticCollection('myExtension');
+context.subscriptions.push(diagnosticCollection);
+
+function updateDiagnostics(document: vscode.TextDocument) {
+    const diagnostics: vscode.Diagnostic[] = [];
+
+    const text = document.getText();
+    const regex = /TODO/g;
+    let match;
+
+    while ((match = regex.exec(text))) {
+        const range = new vscode.Range(
+            document.positionAt(match.index),
+            document.positionAt(match.index + match[0].length)
+        );
+
+        const diagnostic = new vscode.Diagnostic(
+            range,
+            'TODO found',
+            vscode.DiagnosticSeverity.Warning
+        );
+
+        diagnostics.push(diagnostic);
+    }
+
+    diagnosticCollection.set(document.uri, diagnostics);
+}
+```
+
+---
+
+## 10. 调试和诊断
+
+### 10.1 输出通道
+
+```typescript
+const outputChannel = vscode.window.createOutputChannel('My Extension');
+context.subscriptions.push(outputChannel);
+
+outputChannel.appendLine('Extension activated');
+outputChannel.show();  // 显示输出面板
+```
+
+### 10.2 日志记录
+
+```typescript
+// 使用 LogOutputChannel（带时间戳）
+const logger = vscode.window.createOutputChannel('My Extension', { log: true });
+
+logger.trace('Trace message');
+logger.debug('Debug message');
+logger.info('Info message');
+logger.warn('Warning message');
+logger.error('Error message');
+```
+
+### 10.3 错误处理
+
+```typescript
+try {
+    await riskyOperation();
+} catch (error) {
+    if (error instanceof Error) {
+        vscode.window.showErrorMessage(`Error: ${error.message}`);
+        logger.error(error.stack || error.message);
+    }
+}
+```
+
+---
+
+## 最佳实践总结
+
+### ✅ 推荐做法
+
+1. **资源管理**：所有 disposable 对象都放入 `context.subscriptions`
+2. **延迟激活**：使用 `onStartupFinished` 而不是 `*`
+3. **异步操作**：使用 `async/await` 处理异步操作
+4. **错误处理**：捕获异常并给用户友好提示
+5. **类型安全**：充分利用 TypeScript 类型系统
+6. **状态持久化**：使用 `globalState`/`workspaceState` 保存状态
+7. **敏感信息**：使用 `secrets` API 存储 Token、密码等
+
+### ❌ 避免做法
+
+1. 不要在 `activate` 中执行耗时操作
+2. 不要忘记清理资源（监听器、Webview 等）
+3. 不要在 Webview 中直接访问文件系统
+4. 不要在配置中存储敏感信息
+5. 不要阻塞主线程（使用 Worker 或异步操作）
