# The Honest Guide to REA, the AI Reverse Engineering Tool

An 11-minute video guide explaining how REA, an open-source MCP tool for AI-assisted reverse engineering, works and how to try it. It walks through install commands from the README, presents the project's published case studies (a 1996 game function, Aegis Authenticator, Notion's clipboard, a CTF flag checker), and links third-party tests and sources, ending with caveats about scope and responsible use.

## Description

The video covers the workflow step by step: install Node.js 22.19+, run `npx rea-agents setup` and approve the plan, then ask an AI agent plain-language questions about a program, or run `npx -y rea-agents@latest analyze-javascript-application /path/to/app --json` for JavaScript/Electron apps. It notes that native binaries also require Hopper, Ghidra or IDA, and that REA should only be applied to software the user owns or is authorised to analyse, with agent approval prompts kept on. Chapters cover the previous manual approach, how REA works, four showcase examples, an independent test, limitations, and what may come next. All figures and images are cited from the MIT-licensed REA repository and rea.tools, and the description links to the official repo, individual case studies, the DX-Ball reconstruction repository, Cisco Talos' article on LLMs for reverse engineering, and Ghidra.
