Summary
Software that looks right when generated can fall apart after launch, and this video argues the missing ingredient is understanding how real teams built working products. Nate B Jones looks at REA, a reverse-engineering tool that plugs into Claude Code or Codex and lets an AI agent open up software on your computer and show how it is built. The project passed 100,000 GitHub stars within days.
He pushes back on the “death of software” reaction and frames REA as an accelerator for developers and an X-ray machine for non-developers. A published investigation of the Aegis Android authenticator app shows how the six-digit codes come from an account key combined with the current time in 30-second intervals. Another example traces the Windows Calculator percentage button, which behaves differently after addition than after multiplication, to show how much hidden behavior a simple feature contains. One developer also reportedly used REA to study parts of QuickBooks Desktop and then built an independent accounting app.
The video also covers design questions that reverse engineering surfaces, such as clipboard representations, hidden costs, dead ends, and bugs you may not want to copy. A practical look at using AI to understand software before specifying or building your own.
