What it does
Hand Codex the repository link and one image and ask it to install the skin. The agent clones the project, installs the skin engine, generates a theme from the image and applies it. Ready themes and two layouts, banner and fullscreen, are included. According to the author, the styling is injected through the browser engine's debugging interface on a loopback address, and the official app files, the package directory and the `app.asar` archive are not modified. Login and session are kept and projects, tasks and chats are not wiped. One command restores the original: `scripts\restore-dream-skin.ps1` on Windows or `scripts/autoskin-macos.sh uninstall` on macOS. Switch themes with `node scripts\set-theme.mjs <theme> <layout>`; personal themes live separately and are not overwritten by updates.
Who it is for. Codex app users who want a custom theme and are ready to let an agent install a script.
Good fit when
- A reference image should become a Codex app theme.
- Interface readability needs a calm light theme.
- The banner layout is switched to fullscreen with the theme command.
- The original look must be restored with a single command.
Not a fit when
- The Codex app is not installed or has never been opened.
- The theme will be publicly distributed with someone else's artwork.
- Company policy forbids changing the look of work applications.
Example request
Install this Codex skin from the repository link, generate a theme from the attached image and apply it with the banner layout.Limitations
The Codex app must be installed and signed in; Windows and macOS are supported. On macOS Node.js is not installed separately, as the scripts reuse the runtime bundled with the app. The skin applies on a Codex restart, and the script asks for confirmation first. The default debugging port may be taken, in which case set it with `--port`. The author asks not to publish themes built on someone else's images or protected material and to keep personal themes in `themes-private`. After a Codex update the skin may need reapplying. The last commit dates from July 2026.
How to disable. Run `scripts/autoskin-macos.sh uninstall` on macOS or `scripts\restore-dream-skin.ps1` on Windows. Then delete the clone; personal themes sit in `themes-private`.
FAQ
Does it modify Codex app files?
According to the author, no: scripts leave the app directory and `app.asar` alone and inject styling through a local debugging interface.
Are chats and login lost?
No. A normal install uses your existing Codex profile and does not delete projects, tasks, chats or login.
How do I restore the original look?
Run `scripts\restore-dream-skin.ps1` on Windows or `scripts/autoskin-macos.sh uninstall` on macOS.
How do I switch themes?
With `node scripts\set-theme.mjs aurora-veil fullscreen`: the first argument is the theme and the second the layout. The `--list` flag shows themes.
What if the port is taken?
Pick another port at install time, for example `scripts/autoskin-macos.sh install --port 19335`; the choice is remembered.
