 ### 关键架构概念
+
 - **代理认证流**: 客户端用自建API Key → 验证 → 获取Claude账户OAuth token → 转发到Anthropic
 - **Token管理**: 自动监控OAuth token过期并刷新，支持10秒提前刷新策略
 - **代理支持**: 每个Claude账户支持独立代理配置，OAuth token交换也通过代理进行
 - **数据加密**: 敏感数据（refreshToken, accessToken）使用AES加密存储在Redis
 
 ### 主要服务组件

 - `POST /api/v1/messages` - 主要消息处理端点（支持流式）
 - `GET /api/v1/models` - 模型列表（兼容性）
 - `GET /api/v1/usage` - 使用统计查询
 - `GET /api/v1/key-info` - API Key信息

 2. **授权码无效**: 确保复制了完整的Authorization Code，没有遗漏字符
 3. **Token刷新失败**: 检查refreshToken有效性和代理配置
 
 ### Gemini Token刷新问题

 2. **错误日志**: 查看 `logs/token-refresh-error.log` 获取详细错误信息

 ## 开发最佳实践
 
 ### 代码格式化要求
+
 - **必须使用 Prettier 格式化所有代码**
 - 后端代码（src/）：运行 `npx prettier --write <file>` 格式化
 - 前端代码（web/admin-spa/）：已安装 `prettier-plugin-tailwindcss`，运行 `npx prettier --write <file>` 格式化
 - 提交前检查格式：`npx prettier --check <file>`
 - 格式化所有文件：`npm run format`（如果配置了此脚本）
 
+### 前端开发特殊要求
+
+- **响应式设计**: 必须兼容不同设备尺寸（手机、平板、桌面），使用 Tailwind CSS 响应式前缀（sm:、md:、lg:、xl:）
+- **暗黑模式兼容**: 项目已集成完整的暗黑模式支持，所有新增/修改的UI组件都必须同时兼容明亮模式和暗黑模式
+  - 使用 Tailwind CSS 的 `dark:` 前缀为暗黑模式提供样式
+  - 文本颜色：`text-gray-700 dark:text-gray-200`
+  - 背景颜色：`bg-white dark:bg-gray-800`
+  - 边框颜色：`border-gray-200 dark:border-gray-700`
+  - 状态颜色保持一致：`text-blue-500`、`text-green-600`、`text-red-500` 等
+- **主题切换**: 使用 `stores/theme.js` 中的 `useThemeStore()` 来实现主题切换功能
+- **玻璃态效果**: 保持现有的玻璃态设计风格，在暗黑模式下调整透明度和背景色
+- **图标和交互**: 确保所有图标、按钮、交互元素在两种模式下都清晰可见且易于操作
+
 ### 代码修改原则
+
 - 对现有文件进行修改时，首先检查代码库的现有模式和风格
 - 尽可能重用现有的服务和工具函数，避免重复代码
 - 遵循项目现有的错误处理和日志记录模式
 - 敏感数据必须使用加密存储（参考 claudeAccountService.js 中的加密实现）
 
 ### 测试和质量保证
+
 - 运行 `npm run lint` 进行代码风格检查（使用 ESLint）
 - 运行 `npm test` 执行测试套件（Jest + SuperTest 配置）
 - 在修改核心服务后，使用 CLI 工具验证功能：`npm run cli status`
@@ -158,20 +189,26 @@ npm run setup  # 自动生成密钥并创建管理员账户
 - 注意：当前项目缺少实际测试文件，建议补充单元测试和集成测试
 
 ### 开发工作流
+
 - **功能开发**: 始终从理解现有代码开始，重用已有的服务和模式
 - **调试流程**: 使用 Winston 日志 + Web 界面实时日志查看 + CLI 状态工具
 - **代码审查**: 关注安全性（加密存储）、性能（异步处理）、错误处理
 - **部署前检查**: 运行 lint → 测试 CLI 功能 → 检查日志 → Docker 构建
