# 三种工具的使用场景对比示例 # 场景1: Claude Code - 批量重构（终端自动化）$ claude "将所有src/api/下的REST控制器改为GraphQL resolver"> 已分析23个文件，生成18个resolver，迁移了45个查询和12个mutation> 已更新schema.graphql，运行测试通过率 98.5% # 场景2: Cursor - 交互式开发（IDE内联编辑）# 在编辑器中选中一段代码，Cmd+K调出内联编辑# 输入: "添加输入验证和错误处理"# Cursor直接在编辑器中展示diff预览 # 场景3: GitHub Copilot - 实时代码补全# 在VS Code中输入函数签名:# function calculateMonthlyRevenue(transactions: Transaction[]) {# Copilot自动建议函数体实现# Tab键接受建议
