Claude (Anthropic) vs ChatGPT (OpenAI) 对比

// 通过 Claude Code 集成终端 (bash)
# 安装 Claude Code
npm install -g @anthropic-ai/claude-code

# 项目分析
claude "找出并修复本项目中的内存泄漏"

# 基于文件的操作
claude "分析 portfolio/src/lib/firestore.ts 文件，
  列出导致不必要重渲染的问题"

# Git 集成
claude "审查最近 5 次提交，是否有破坏性变更？"

# 编写测试
claude "用 XCTest 为 CartViewModel 编写全面的测试套件"

# 示例 Claude API 用法 (Swift)
