+- 使用 ESLint 进行代码规范检查
-- 工具函数和普通文件使用 camelCase (如 `imageUtils.ts`, `useAppStore.ts`)
+- 使用 Prettier 进行代码格式化 (通过 ESLint 配置集成)
-- 常量使用 UPPER_SNAKE_CASE
+- 组件文件使用 `.tsx` 扩展名
-- 变量和函数使用 camelCase
+- 工具函数文件使用 `.ts` 扩展名
-- 组件 Props 接口命名为组件名 + Props (如 `ButtonProps`)
-- Hook 函数以 use 开头 (如 `useAppStore`, `useImageGeneration`)
 
-## 样式和 UI 框架
+### 项目结构约定
-
-### Tailwind CSS
-- 使用自定义颜色方案，以香蕉黄 (banana) 为主题色
-- 定义了 light 主题颜色 (背景、面板、边框、文字等)
-- 使用自定义间距、阴影和动画
-- 使用 tailwind-merge 和 clsx 进行类名合并
-
-### 组件设计
-- 使用 Radix UI 构建无样式的可访问组件
-- 自定义 UI 组件位于 `src/components/ui` 目录
-- 组件变体使用 class-variance-authority 管理
-- 图标使用 Lucide React

-## 核心功能模块
+### 组件开发
 
-### 1. 图像画布 (ImageCanvas)
+- 组件应保持较小的体积（建议小于200行）
-- 使用 Konva 和 react-konva 实现图像显示和编辑
+- 使用函数式组件和 React Hooks
-- 支持图像缩放、平移
+- 组件应具有明确的接口（Props）
-- 实现画笔工具进行遮罩绘制
+- 尽可能使用 TypeScript 进行类型定义
-- 支持图像下载功能
 
-### 2. 提示词编辑 (PromptComposer)
+### 状态管理
-- 用户输入提示词生成图像
-- 提供提示词建议功能
-- 集成 AI 模型参数调整 (如风格、质量等)
 
-### 3. 历史记录 (HistoryPanel)
+- 全局状态使用 Zustand 管理 (`src/store/useAppStore.ts`)
-- 显示生成的图像历史
+- 服务端状态使用 React Query 管理
-- 支持历史图像的查看和重新编辑
+- 组件内部状态使用 React 的 useState 和 useReducer
-- 使用 IndexedDB 存储历史数据
 
-### 4. 状态管理 (useAppStore)
+### 测试
-- 使用 Zustand 管理全局状态
-- 存储画布状态、用户设置、历史记录等
-- 提供状态操作方法
 
-### 5. AI 服务 (geminiService)
+- 使用 Jest 和 React Testing Library 进行测试
-- 集成 Google Gemini AI 模型
+- 测试文件放在 `src/__tests__` 目录下
-- 实现图像生成和编辑功能
+- 测试文件名应与被测试文件名对应，加上 `.test.tsx` 或 `.test.ts` 后缀
-- 处理与 AI 模型的交互
 
-## 开发环境配置
+### 贡献指南
 
-1. 安装依赖: `npm install`
+1. 遵循既定的代码风格和项目结构
-2. 启动开发服务器: `npm run dev`
+2. 保持组件在 200 行以内
-3. 构建生产版本: `npm run build`
+3. 维护类型安全，严格使用 TypeScript 和正确定义
-4. 代码检查: `npm run lint`
+4. 彻底测试，确保键盘导航和可访问性
-
+5. 记录更改，更新 README 并添加内联注释
-## 注意事项
+6. 遵守 AGPL-3.0 许可证
-
-- 项目使用 IndexedDB 存储图像数据，需要注意存储空间管理
-- AI 功能需要配置 Google API 密钥
-- 图像处理功能依赖浏览器 Canvas API
-- 移动端适配需要特别关注界面布局和交互
