Score: 5.5/10 (Innovation: 5, Technical: 5, Documentation: 8, Utility: 4)

This project patches OpenAI's ChatGPT browser extension to make Codex's browser control work in the Arc browser, which lacks Chrome's tab-group API. It downloads the extension, applies small binary patches, and rebuilds a compatible version locally on macOS. It's a niche but well-executed compatibility fix for a specific tooling gap.

Target audience: macOS developers using Arc and OpenAI Codex
