+
+Chrome API Usage:
+- Properly use chrome.* APIs (storage, tabs, runtime, etc.)
+- Handle asynchronous operations with Promises
+- Use Service Worker for background scripts (MV3 requirement)
+```typescript
+// Storage API example
+const storage = {
+  get: async <T>(key: string): Promise<T | undefined> => {
+    const result = await chrome.storage.local.get(key);
+    return result[key];
+  },
+  set: async <T>(key: string, value: T): Promise<void> => {
+    await chrome.storage.local.set({ [key]: value });
+  }
+};
+
+// Tabs API example
+const tabs = {
+  getCurrentTab: async () => {
+    const [tab] = await chrome.tabs.query({
+      active: true,
+      currentWindow: true
+    });
+    return tab;
+  }
+};
+```
+
+Security and Privacy:
+- Implement Content Security Policy (CSP)
+- Handle user data securely
+- Prevent XSS and injection attacks
+- Secure component communication
+- Handle cross-origin requests safely
+```typescript
+// Secure message passing
+chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
+  if (!sender.id || sender.id !== chrome.runtime.id) {
+    return;
+  }
+  // Process message
+});
+```
+
+Performance Optimization:
+- Minimize useEffect and setState usage
+- Use dynamic loading for non-critical components
+- Implement appropriate caching strategies
+```typescript
+// Caching strategy example
+const CACHE_DURATION = 1000 * 60 * 5; // 5 minutes
+
+async function fetchWithCache<T>(key: string, fetcher: () => Promise<T>): Promise<T> {
+  const cached = await storage.get<{ data: T; timestamp: number }>(key);
+
+  if (cached && Date.now() - cached.timestamp < CACHE_DURATION) {
+    return cached.data;
+  }
+
+  const data = await fetcher();
+  await storage.set(key, { data, timestamp: Date.now() });
+  return data;
+}
+```

+# Code Commenting Guidelines
+
+## 基本原则 Basic Principles
+- 注释应该解释**为什么**这样做，而不是**做了什么**
+- 代码即文档，仅在必要时添加注释
+- 使用清晰简洁的语言，避免冗余, English
+- 及时更新注释，确保与代码同步
+
+## 文件头注释 File Header Comments
+```typescript
+/**
+ * @file 文件的简要描述
+ * @description 详细描述文件的功能和用途
+ * @author [作者名称]
+ * @date YYYY-MM-DD
+ */
+```
+
+## 函数注释 Function Comments
+```typescript
+/**
+ * 函数的简要描述
+ * @description 详细描述函数的功能
+ * @param {string} param1 - 参数1的描述
+ * @param {number} param2 - 参数2的描述
+ * @returns {Promise<boolean>} 返回值的描述
+ * @throws {Error} 可能抛出的错误
+ * @example
+ * const result = await someFunction('test', 123);
+ */
+function someFunction(param1: string, param2: number): Promise<boolean> {
+  // ...
+}
+```
+
+## 行内注释 Inline Comments
+```typescript
+// ✅ 好的注释：解释复杂的业务逻辑
+if (user.role === 'admin' && !isHoliday) {
+  // 管理员在非假日期间具有特殊权限
+  grantSpecialAccess();
+}
+
+// ❌ 不好的注释：陈述显而易见的事实
+// 检查用户是否为管理员
+if (user.role === 'admin') {
+  // ...
+}
+```
+
+## 待办注释 TODO Comments
+```typescript
+// TODO(github-username): 实现用户认证功能 (#123)
+// FIXME(github-username): 修复内存泄漏问题 (#456)
+// NOTE: 这里使用递归可能会导致性能问题
+```
+
+## 类型定义注释 Type Definition Comments
+```typescript
+/**
+ * 用户配置接口
+ * @interface UserConfig
+ * @property {string} name - 用户名
+ * @property {number} age - 年龄
+ * @property {string[]} permissions - 权限列表
+ */
+interface UserConfig {
+  name: string;
+  age: number;
+  permissions: string[];
+}
+```
+
+## 常量和枚举注释 Constants and Enum Comments
+```typescript
+/**
+ * 用户角色枚举
+ * @enum {string}
+ */
+enum UserRole {
+  /** 管理员用户 */
+  ADMIN = 'admin',
+  /** 普通用户 */
+  USER = 'user',
+  /** 访客用户 */
+  GUEST = 'guest',
+}
+
+/** 最大重试次数 */
+const MAX_RETRY_COUNT = 3;
+```
+
+## 弃用注释 Deprecation Comments
+```typescript
+/**
+ * @deprecated 从 v2.0.0 开始弃用，请使用 `newFunction()` 替代
+ * @see {@link newFunction}
+ */
+function oldFunction() {
+  // ...
+}
+```
+
+## 区块注释 Section Comments
+```typescript
+//===================================
+// 初始化配置
+//===================================
+
+//===================================
+// 工具函数
+//===================================
+
+//===================================
+// 事件处理
+//===================================
+```
+
+## 注释规范检查 Comment Linting
+- 使用 ESLint 的 `eslint-plugin-jsdoc` 插件检查注释格式
+- 在 CI/CD 流程中包含注释检查
+- 定期审查和更新过时的注释
+
+## 最佳实践 Best Practices
+- 使用 JSDoc 风格的注释以获得更好的 IDE 支持
+- 为公共 API 和复杂的业务逻辑编写详细注释
+- 避免注释掉的代码，使用版本控制系统代替
+- 定期清理无用和过时的注释

+Internationalization (i18n) Guidelines:
+
+Message Structure:
+- Store all text content in `/locales/[locale]/messages.json`
+- Use descriptive message keys in camelCase: `errorImportingContent`
+- Include placeholders with $PLACEHOLDER$ syntax
+- Add descriptions for translators in message files
+- `console.log` don't need add i18n, only for UI text display on screen
+
+Message Format:
+```json
+"extensionDisplayName": {
+  "message": "MultiPost",
+  "description": "Multipost Extension"
+},
+```
+
+Implementation:
+- Use `chrome.i18n.getMessage('extensionDisplayName')` for all user-facing text
+- Never hardcode text strings in UI components
+- Handle RTL languages with appropriate CSS
+- Set default_locale in manifest.json
+- Support fallback locales
+
+Best Practices:
+- Keep messages concise and clear
+- Use semantic keys (e.g., WELCOME_MESSAGE vs MSG_001)
+- Maintain consistent terminology across translations
+- Handle pluralization properly
+- Consider cultural differences in formatting dates, numbers, and currencies
+- Test UI with different language lengths
+
+Code Examples:
+```typescript
+// Component usage
+const message = chrome.i18n.getMessage("WELCOME_MESSAGE", [username]);
+
+// Manifest configuration
+{
+  "default_locale": "en",
+  "name": "__MSG_extension_name__",
+  "description": "__MSG_extension_description__"
+}
+```
