+description: Trae 开发规则，定义如何使用 Trae 进行项目开发和维护
+globs: src/**/*
+alwaysApply: true
+---
+
+# Trae 开发规则
+
+**使用 Trae 进行开发时必须遵循的规则**，确保代码质量和开发效率。
+
+## 开发流程
+
+1. **需求分析**：理解用户需求，明确功能边界
+2. **代码实现**：按照项目框架规范实现功能
+3. **测试验证**：确保功能正常工作
+4. **文档更新**：同步更新相关文档
+5. **代码检查**：运行 lint 和类型检查
+
+## 代码规范
+
+### 1. 代码风格
+- 遵循项目现有的代码风格（Prettier + ESLint）
+- 使用 TypeScript 严格模式
+- 避免使用 `any` 类型
+- 函数和变量命名清晰，符合语义
+
+### 2. 组件开发
+- 使用 Vue 3 Composition API
+- 组件文件使用 PascalCase 命名
+- 样式使用 `<style scoped>`
+- 组件 props 和 emits 必须有类型定义
+
+### 3. API 开发
+- 遵循 XTrader API 接入规范
+- 使用统一的请求封装（`src/api/request.ts`）
+- 为每个接口定义完整的 TypeScript 类型
+- 处理错误和边界情况
+
+## 工具使用
+
+### 1. 代码生成
+- 使用 Trae 的代码生成功能创建组件、接口等
+- 生成的代码必须符合项目规范
+- 手动调整生成的代码，确保质量
+
+### 2. 调试工具
+- 使用 Trae 的调试功能排查问题
+- 利用 Trae 的搜索功能快速定位代码
+- 结合浏览器开发工具进行前端调试
+
+## 最佳实践
+
+1. **模块化开发**：将功能拆分为小的、可维护的模块
+2. **代码复用**：提取公共组件和工具函数
+3. **性能优化**：注意组件渲染性能，避免不必要的重渲染
+4. **安全性**：注意处理用户输入，避免安全漏洞
+5. **可访问性**：确保界面对所有用户可访问
+
+## 检查清单
+
+开发完成后，确保：
+
+- [ ] 代码符合项目框架规范
+- [ ] 功能正常工作
+- [ ] 文档已同步更新
+- [ ] 无 lint 和类型错误
+- [ ] 代码风格一致
+- [ ] 测试通过
+
+遵循这些规则，使用 Trae 可以更高效、更规范地进行项目开发。

+
+# Trae 开发技能
+
+## 功能介绍
+
+本技能提供 Trae 开发环境的使用指南，帮助开发者更高效地使用 Trae 进行项目开发和维护。
+
+## 使用场景
+
+- 代码生成：创建新组件、接口、页面等
+- 代码搜索：快速定位代码和文件
+- 代码分析：理解现有代码结构
+- 调试工具：排查和解决问题
+- 项目管理：项目结构和规范管理
+
+## 核心功能
+
+### 1. 代码生成
+
+#### 组件生成
+
+**使用方式**：
+- 在命令面板中输入 `Trae: Generate Component`
+- 选择组件类型（如 Vue 组件、TypeScript 接口等）
+- 输入组件名称和相关选项
+- Trae 会自动生成符合项目规范的代码
+
+**生成的组件结构**：
+- Vue 组件：包含 template、script setup 和 scoped style
+- TypeScript 接口：包含完整的类型定义
+- API 模块：包含请求函数和类型定义
+
+### 2. 代码搜索
+
+**使用方式**：
+- 在命令面板中输入 `Trae: Search Code`
+- 输入搜索关键词
+- Trae 会显示所有匹配的代码片段
+- 点击结果可直接跳转到对应文件
+
+**搜索范围**：
+- 项目代码库
+- 依赖库
+- 文档
+
+### 3. 代码分析
+
+**使用方式**：
+- 在命令面板中输入 `Trae: Analyze Code`
+- 选择分析类型（如依赖分析、性能分析等）
+- Trae 会生成详细的分析报告
+
+**分析内容**：
+- 代码复杂度
+- 依赖关系
+- 性能瓶颈
+- 代码质量
+
+### 4. 调试工具
+
+**使用方式**：
+- 在命令面板中输入 `Trae: Debug Code`
+- 设置断点或选择调试模式
+- 运行调试会话
+- Trae 会提供详细的调试信息
+
+**调试功能**：
+- 断点设置
+- 变量监视
+- 调用栈查看
+- 表达式求值
+
+### 5. 项目管理
+
+**使用方式**：
+- 在命令面板中输入 `Trae: Project Management`
+- 选择管理功能（如依赖管理、版本控制等）
+- 执行相应的管理操作
+
+**管理功能**：
+- 依赖安装和更新
+- 版本控制操作
+- 项目配置管理
+- 构建和部署
+
+## 最佳实践
+
+1. **代码组织**：
+   - 按照项目框架规范组织代码
+   - 使用清晰的命名和目录结构
+   - 遵循模块化开发原则
+
+2. **代码质量**：
+   - 定期运行 lint 和类型检查
+   - 编写单元测试
+   - 保持代码风格一致
+
+3. **开发效率**：
+   - 使用 Trae 的代码生成功能
+   - 利用搜索功能快速定位代码
+   - 结合调试工具排查问题
+
+4. **团队协作**：
+   - 遵循统一的代码规范
+   - 及时更新文档
+   - 提交有意义的代码注释
+
+## 常见问题
+
+### Q: 如何使用 Trae 生成组件？
+
+**A**: 在命令面板中输入 `Trae: Generate Component`，选择组件类型和配置选项，Trae 会自动生成符合项目规范的代码。
+
+### Q: 如何搜索项目中的代码？
+
+**A**: 在命令面板中输入 `Trae: Search Code`，输入搜索关键词，Trae 会显示所有匹配的代码片段。
+
+### Q: 如何调试代码？
+
+**A**: 在命令面板中输入 `Trae: Debug Code`，设置断点或选择调试模式，运行调试会话查看详细信息。
+
+### Q: 如何分析项目依赖？
