Codex 2006 is a visual skin that makes the Codex Desktop app look like a blue QQ instant messenger window from around 2006. QQ was a popular Chinese chat client, and this project recreates its classic blue color scheme, double bordered edges, dense toolbars, and grouped layout style as decoration on top of Codex Desktop, without changing how Codex actually works underneath. The project describes itself as a clean room implementation, meaning the visuals are built from original CSS and images rather than files copied out of the real QQ client. It does not create a second application, fake window, or fake navigation. There is no background service, backend server, database, or separate account system when running normally. The skin only adds a non interactive decorative layer on top of Codex's existing interface, which stays the one part you actually click and type into. On macOS, the title bar area is left alone so the system's own window buttons still show. To check that it is looking at the real Codex app and not something else, the installer verifies the official app's identity, code signature, and packaging details before doing anything, and it only ever connects to your own computer, refusing any remote connections. It does not modify the app's installed files, its code signature, or macOS's system protections. Installation is done through matching Windows PowerShell and macOS shell scripts that all support the same set of commands: checking system readiness, a dry run, the actual install, verifying it worked, and later restoring, uninstalling, or fully purging the skin along with its logs. Installing does not launch or restart Codex on its own. There is also a local preview app, built with pnpm, for developers to review the visual design during development, though this preview does not connect to or affect the real Codex app. The README is explicit that this is not an official Tencent or OpenAI product, and that full real world compatibility across every Codex version and machine has not yet been verified end to end. The code and original assets are released under the MIT license.
