• Nate B. Jones introduces REA (Reverse Engineer Anything) as a tool that allows AI models like Claude Code or OpenAI Codex to analyze existing software, revealing its inner workings and demonstrating “what real software has to do” beyond superficial “vibe-coded” appearances.
• He argues that REA isn’t the “death of software,” but rather a critical method for understanding how applications function, which is increasingly vital as AI agents write more code, shifting the advantage to those who understand what software should do.
• Key examples illustrate REA’s utility, such as reverse engineering an authenticator app’s code generation, understanding Notion’s copy/paste mechanics, and deriving real requirements from a calculator’s percent button, showing how to turn research into robust software specifications.
• The practical takeaway is that REA empowers both developers and non-developers to deeply understand existing software, extract concrete requirements, and learn best practices, ultimately enabling them to build more resilient and functional applications.
