+## Gotchas & Troubleshooting
+
+- **Umi cache issues**: If dev server behaves unexpectedly, delete `src/.umi` and restart. This directory is auto-generated and safe to remove.
+- **Port 8000 in use**: Umi defaults to port 8000. Use `PORT=3000 npm start` to change it.
+- **Mock not updating**: Restart dev server after adding new mock files; Umi auto-discovers `mock/` and `src/pages/**/_mock.ts` on startup only.
+- **`npm run simple` is irreversible**: Always commit before running it — it deletes demo pages and replaces routes.
+- **Biome + ESLint conflict**: This project uses Biome only. Do not install ESLint or Prettier plugins.
+- **Lock file**: Uses `package-lock.json`. If deps break, delete `node_modules` and reinstall.

+## Common Tasks
+
+### Add a New Page
+
+```bash
+# 1. Create the page component
+#    File: src/pages/my-page/index.tsx
+
+# 2. Register in route config
+#    File: config/routes.ts
+#    { path: '/my-page', name: 'myPage', icon: 'file', component: './my-page' }
+
+# 3. Add i18n translations (for menu display)
+#    File: src/locales/zh-CN/menu.ts → menu.myPage: '我的页面'
+#    File: src/locales/en-US/menu.ts → menu.myPage: 'My Page'
+```
+
+### Add Global State
+
+```bash
+# 1. Create a model file (filename becomes the model key)
+#    File: src/models/myModel.ts
+#    Export a custom Hook: export default function useMyModel() { ... }
+
+# 2. Use in components
+#    import { useModel } from '@umijs/max';
+#    const { data } = useModel('myModel');  // 'myModel' matches filename
+```
+
+### Add a Mock API
+
+```bash
+# Global mock: mock/api.ts (applies to all environments)
+# Page-level mock: src/pages/my-page/_mock.ts (auto-discovered by Umi)
+
+# Mock format:
+# export default { 'GET /api/my-data': { data: [] } }
+```
+
+### Generate API Service Code
+
+```bash
+# 1. Edit OpenAPI config: config/oneapi.json
+# 2. Run generation (overwrites src/services/ant-design-pro/)
+npm run openapi
+# 3. Never edit generated code manually — modify oneapi.json and regenerate
+```
+
+### Switch to Simple Mode
+
+```bash
+git add -A && git commit -m "chore: save before simple"  # Must commit first
+npm run simple                                              # Irreversible
+npm install                                                 # Update dependencies
+```
+
+## Constraints & Gotchas
+
+- **`src/services/ant-design-pro/`** is auto-generated code. Do NOT edit manually. Modify `config/oneapi.json` and run `npm run openapi` to regenerate.
+- **`npm run simple` is irreversible**: It deletes demo pages and unused dependencies. Always commit before running.
+- **`.umi` temp directory**: `src/.umi` is auto-generated by Umi. Delete it and restart the dev server if you encounter unexpected behavior.
+- **Biome over ESLint**: This project uses Biome for linting and formatting. Do not install ESLint or Prettier plugins.
+- **Commit convention**: Must follow [Conventional Commits](https://www.conventionalcommits.org/) (e.g., `feat:`, `fix:`, `chore:`).
+- **`npx antd lint ./src`**: Must pass with zero errors and warnings before committing.
+- **Mock priority**: `mock/` directory for global mocks, `src/pages/**/_mock.ts` for page-level mocks. Both are auto-registered by Umi.
+- **Styling priority**: Tailwind (layout) > antd-style (theme tokens) > CSS Modules (component styles) > Less (legacy global styles only).
+- **Path aliases**: `@/*` → `./src/*`, `@@/*` → `./src/.umi/*`

+## 常见任务
+
+### 添加新页面
+
+```bash
+# 1. 创建页面组件
+#    文件路径：src/pages/my-page/index.tsx
+
+# 2. 在路由配置中注册
+#    文件路径：config/routes.ts
+#    { path: '/my-page', name: 'myPage', icon: 'file', component: './my-page' }
+
+# 3. 添加国际化翻译（如需菜单显示）
+#    文件路径：src/locales/zh-CN/menu.ts → menu.myPage: '我的页面'
+#    文件路径：src/locales/en-US/menu.ts → menu.myPage: 'My Page'
+```
+
+### 添加全局状态
+
+```bash
+# 1. 创建 model 文件（文件名即 model key）
+#    文件路径：src/models/myModel.ts
+#    导出自定义 Hook：export default function useMyModel() { ... }
+
+# 2. 在组件中使用
+#    import { useModel } from '@umijs/max';
+#    const { data } = useModel('myModel');  // 'myModel' 对应文件名
+```
+
+### 添加 Mock 接口
+
+```bash
+# 全局 Mock：mock/api.ts（匹配所有环境）
+# 页面级 Mock：src/pages/my-page/_mock.ts（Umi 自动发现）
+
+# Mock 格式：
+# export default { 'GET /api/my-data': { data: [] } }
+```
+
+### 生成 API 服务代码
+
+```bash
+# 1. 编辑 OpenAPI 配置：config/oneapi.json
+# 2. 运行生成命令（覆盖 src/services/ant-design-pro/）
+npm run openapi
+# 3. 不要手动编辑生成代码，改 oneapi.json 重新生成
+```
+
+### 切换到精简模式
+
+```bash
+git add -A && git commit -m "chore: save before simple"  # 必须先提交
+npm run simple                                              # 不可逆操作
+npm install                                                 # 更新依赖
+```
+
+## 注意事项
+
+- **`src/services/ant-design-pro/`** 为自动生成代码，禁止手动编辑。修改 `config/oneapi.json` 后执行 `npm run openapi` 重新生成
+- **`npm run simple` 不可逆**：会删除示例页面和多余依赖，执行前务必提交代码
+- **`.umi` 临时目录**：`src/.umi` 由 Umi 自动生成，遇到异常可删除后重启开发服务器
+- **Biome 代替 ESLint**：项目使用 Biome 进行 lint 和格式化，不要安装 ESLint 或 Prettier 插件
+- **Commit 规范**：必须遵循 [Conventional Commits](https://www.conventionalcommits.org/)，如 `feat:`, `fix:`, `chore:` 等
+- **`npx antd lint ./src`**：提交前必须零错误零警告
+- **Mock 优先级**：`mock/` 目录为全局 Mock，`src/pages/**/_mock.ts` 为页面级 Mock，两者都会被 Umi 自动注册
+- **样式优先级**：Tailwind（布局）> antd-style（主题 token）> CSS Modules（组件样式）> Less（仅遗留全局样式）
+- **路径别名**：`@/*` → `./src/*`，`@@/*` → `./src/.umi/*`
