# 你的憑感覺編程應用程式可能看起來沒問題，但上線後就崩潰。REA 向您展示真實團隊是如何建構的。

Nate B Jones 透過 Claude Code / Codex 演示了 REA（Reverse Engineer Anything，逆向工程任何東西）的具體用法：驗證器應用程式如何產生六位數驗證碼，Notion 的複製貼上如何運作，為什麼 Windows 小算盤的百分比按鈕很重要，以及 Ledger Reborn 在建構會計應用程式之前如何研究 QuickBooks。

## Description

一個22分鐘的影片加上連結的 Substack 深度分析，展示了 REA（Reverse Engineer Anything）如何讓 Claude Code 或 OpenAI Codex 開啟您機器上的軟體，並解釋其實際運作原理。章節涵蓋驗證器應用程式驗證碼的推導、Notion 的剪貼簿行為、Windows 小算盤的百分比按鈕、Ledger Reborn 背後的 QuickBooks 調查，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.

Chapters:
00:00 Why REA is bigger than cloning software
01:05 How an authenticator app makes its codes
03:09 Why REA isn't the death of software
03:38 Two jobs REA does for non-developers
04:28 Turning a research tool idea into requirements
05:43 How Notion's copy and paste really works
08:49 Asking why software was built that way
11:01 The Windows calculator percentage button
13:20 Ledger Reborn and the QuickBooks investigation
16:30 For developers: the dinosaur game and DX-Ball
18:46 Tell REA how deep to go
19:52 Getting started and what REA can't see
