Recommended: REA, reverse engineering with your agent

Everyone is talking about REA (Reverse Engineer Anything), an open source project by morluto, and it's worth the noise. The pitch fits in one sentence: you see a feature in someone else's app and ask your agent to figure out how it works, without the source code, with evidence for every conclusion. It installs an MCP server and a skill that teaches the agent to pick the right tool for each target (an Electron app, a website, a native binary), and everything runs on your machine. I installed it and the first test already taught me something: Linear's desktop app is mostly a shell, and the interface comes from the website. Two cautions. Pin a version when you install it, instead of letting the agent pull the latest one on its own. And use it to understand, not to copy: explaining how something works is learning, publishing someone's decompiled code isn't.
