Developers leveraged the open-source tool REA (Reverse Engineer Anything) with AI agents to reverse-engineer the browser annotation mechanism in the Codex/ChatGPT App. By having the AI analyze raw Electron code instead of traditional decompilation, they uncovered an undocumented `document.oai.annotation.request()` API, enabling custom web pages to inject content into the Codex composer.

    • REA integrates as an MCP service with agents like Claude Code/Codex to automate analysis of Electron, native binaries, and other formats.
    • For Electron apps like Codex, AI directly parses JS code within ASAR archives, bypassing complex machine-code disassembly.
    • The method successfully located OpenAI's internal `document.oai.annotation.request()` API, revealing how frontend components communicate with the host application.
