# 你的凭感觉编程应用可能看起来没问题，但上线后就崩溃。REA 向你展示真实团队是如何构建的。

Nate B Jones 通过 Claude Code / Codex 演示了 REA（Reverse Engineer Anything，逆向工程任何东西）的具体用法：认证器应用如何生成六位数验证码，Notion 的复制粘贴如何工作，为什么 Windows 计算器的百分比按钮很重要，以及 Ledger Reborn 在构建会计应用之前如何研究 QuickBooks。

## Description

一个22分钟的视频加上链接的 Substack 深度分析，展示了 REA（Reverse Engineer Anything）如何让 Claude Code 或 OpenAI Codex 打开你机器上的软件，并解释其实际工作原理。章节涵盖认证器应用验证码的推导、Notion 的剪贴板行为、Windows 计算器的百分比按钮、Ledger Reborn 背后的 QuickBooks 调查，以及控制 REA 深入程度及其局限性的技巧。

## Original README

Your Vibe-Coded App Can Look Right And Fall Apart After Launch. REA Shows You How Real Teams Build.

REA (Reverse Engineer Anything) lets Claude Code or OpenAI Codex open up the software on your computer and show you how it actually works. If you've ever vibe-coded an app that looked right and fell apart after launch, this is how you learn what real software has to do.

What's really happening with REA?

The common story is that REA means the death of software, but the real question is how few of us understand the software we already use, let alone the software we're trying to build.

In this video, I share the inside scoop on using REA to understand software:
- How an authenticator app turns a key and the clock into six digits
- What Notion's copy and paste reveals about building your own editor
- Why a calculator's percent button shows what a real requirement looks like
- How Ledger Reborn used a QuickBooks investigation to build a new accounting app

Agents can write more of the code now, so the people who understand what software should do, developers or not, get the biggest advantage.
