# Reverse Engineer Any App With Claude Code (REA Tested)

A 02UI video demo showing how to use REA (Reverse Engineer Anything) with Claude Code to study Apple's Passwords generator and rebuild its 17 password rules inside the team's own design system, then validate with a 100-password test.

## Description

The video walks through what REA can open (web, Mac, Android, iOS apps), shares the exact prompt used, explains Apple's password generator rules, and shows how to install REA and turn it into a Claude Code skill. Repo referenced: https://github.com/morluto/rea.
