# REA + Claude Code 通过一个应用追踪一项功能 REA (Reverse Engineer Anything

REA + Claude Code 通过一个应用追踪一项功能 REA (Reverse Engineer Anything

## Description

REA + Claude Code 通过一个应用追踪一项功能

REA (Reverse Engineer Anything) 是一个免费工具，可以将你的编码智能体连接到应用的文件。其官方指南提供了以下提示

使用 REA 找出我在这个应用中导出笔记时会发生什么。CSV 是在哪里创建的？

指南的示例应用给出的答案
→ 按钮调用页面中的 API
→ API 向内发送一条命名消息 (IPC)
→ 主进程中的一个处理器捕获它
→ 该处理器将 notes.csv 写入 Downloads

REA 将 1 条消息匹配到 1 个处理器，0 个模糊。指南明确表示，路径是从代码推断出来的，而运行时捕获是检查实际运行内容的方式

示例是 https://t.co/IY2xhc73j1 上的一个小型 zip 文件。它只需要 Node.js 和 npm，无需安装 Electron

Claude Code 在 REA 的设置列表中，与 Codex、Cursor、Gemini CLI 和 Grok Build 并列

## Original README

REA + Claude Code traces a feature through an app

REA (Reverse Engineer Anything) is the free tool that connects your coding agent to an app's files. Its official guide hands you the prompt

Use REA to find what happens when I export notes in this app. Where is the CSV created?

What the guide's example app answers
→ the button calls an API in the page
→ the API sends a named message (IPC) inward
→ one handler in the main process catches it
→ that handler writes notes.csv to Downloads

REA matched 1 message to 1 handler, with 0 ambiguous. The guide says plainly that the path is inferred from code, and a runtime capture is how you check what really runs

The example is a small zip on http://rea.tools. It needs only Node.js and npm, no Electron install

Claude Code is on REA's setup list, next to Codex, Cursor, Gemini CLI and Grok Build
