Claude Code 現在可以向你展示幾乎任何應用程式如何運作，以及你可以如何重現

Claude Code can now show you how basically any app works, and how you can recreate it... It's called REA, an open source tool that hit #1 on GitHub this month Basically, you don't need an app's source code anymore to understand it. You ask Claude how a feature works, and it shows you how Here's how i'd set it up: Step 1: paste this into Claude Code: “Install REA from the official morluto/rea repo. Check that I have Node.js 22 or 24, run the REA setup for Claude Code, then install Ghidra and Java 21 or newer and connect them to REA. Tell me when I need to approve something or restart” Step 2: approve the setup changes and restart Claude Code Step 3: ask about one feature, for example: “Understand how search works in [app], show me the evidence, and build a similar feature for my project” Way better than guessing how something works from the outside One thing to note: fake copies with trojans showed up during the hype, so only install from the official morluto/rea repo
