What is awesome-codex-skins?

awesome-codex-skins is a gallery and toolkit of visual themes for the official OpenAI Codex desktop app. It defines its own file format, called codexskin, for packaging a full custom look for the app, including images and layout changes, rather than just swapping a color palette. The themes are applied by connecting live to the running Codex app through Chrome DevTools Protocol, the same debugging connection browsers expose, instead of editing any of the app's own files. This means the app's original signature stays intact and the change can be turned off instantly with a single command, returning the app to its normal look with nothing left behind. The repository includes a gallery of dozens of finished themes, each with a name and a preview screenshot taken from the real app while a theme was active, covering styles based on anime characters, historical settings, and other pop culture references. Users can try a theme through a companion desktop app called Codex App Manager, which offers one click switching and permanent application, or through a command line tool included in this repository that starts Codex in debug mode and injects a chosen theme, switches between themes without restarting, or turns everything off. The project also ships an agent skill that can be used with tools like Claude Code or Codex itself, letting a person describe a desired style in plain language and have the agent generate the needed image assets, build the matching styling, and package it into a finished skin file. Anyone can submit a new theme as a pull request, and submissions go through an automated check that verifies the file format, image sizes, and real screenshots before being listed. The project's code is released under the MIT license.
