Reverse Engineer Anything

Any feature you find intriguing can be reversed engineered to gain a deeper understanding, down to the binary level. The Reverse Engineer Anything (REA) tool enables this by connecting your agent to various analysis tools without requiring the source code. REA can inspect native binaries, JavaScript and Electron apps, .NET assemblies, and websites. Analysis runs locally, providing evidence and limitations for each conclusion.

Setting up REA involves registering it with your agent and installing workflow instructions. For native analysis, Hopper or Ghidra installations can be used. Static JavaScript analysis does not require any engine. The tool supports multiple agents, such as Claude Code, Codex, Cursor, Gemini CLI, Grok Build, and more. Setup adds REA's MCP server and workflow instructions, with backups of the existing configuration. Restarting your agent is necessary after setup.

To inspect an app, replace the placeholder with your target app and the feature you want to understand. For JavaScript/Electron apps, extract the app directory or ASAR file. For native analysis, configure a provider first. REA changes frequently, so keep your installation up to date by refreshing agent registrations and skills. If issues persist, open an issue with your REA version, target type, steps to reproduce, and error output.

REA analyzes targets locally, providing the results to your agent. Your agent utilizes this information to write and test an implementation. The tool supports various providers, including Hopper, Ghidra, IDA, and others, each with its own setup instructions. By following the guides and case studies provided, you can learn how to effectively use REA for reverse engineering tasks.
