What it does
Codex Document Mode formats replies in the Codex desktop app as Chinese official documents: a header, salutation, title, body and a signature with a date. Code blocks, commands and tables keep their usual form. On send, a formal-style requirement is added to the request temporarily and the original text is restored afterwards. A square for marking appears left of the input: a circle means agree, a cross means disagree, and the recognised answer is inserted as `【反馈：同意】` or `【反馈：不同意】`. The styling is injected locally through the DevTools protocol (CDP) without touching `.app`, `app.asar` or `WindowsApps`. Windows (built on Codex Dream Skin) and macOS versions exist.
Who it is for. Desktop Codex users who like a formal reply style and marking with a gesture instead of text.
Good fit when
- A Codex reply should look structured like a memo, with a closing line.
- Approval or rejection of an agent proposal is quicker as a gesture.
- A team prepares a demo or stream and wants an unusual Codex look.
- The original theme should come back with a single restore script.
Not a fit when
- Codex runs in a browser or terminal, while the add-on targets the desktop app only.
- Company policy bans modifying client apps or opening a debug port.
- Replies must be neutral English, while the styling is tuned for Chinese official texts.
Example request
Read the Windows README, run the environment check `doctor-dream-skin.ps1` and show the report before installing.Limitations
Not an OpenAI product. The author calls the tool entertainment and study material and disclaims liability for consequences. Windows needs the `OpenAI.Codex` Microsoft Store app, Node.js 22 or newer and PowerShell 5.1 or newer; on macOS automated fixtures pass but final acceptance on a real Mac with official Codex is still pending. Reapply after a Codex update. The README is in Chinese, with an English Windows version.
How to disable. Run the restore script: `restore-dream-skin.ps1` on Windows or `restore-dream-skin-macos.sh --restore-base-theme --restart-codex` on macOS. Then remove the installer shortcuts.
FAQ
Does installation change Codex files?
No: `.app`, `app.asar` and `WindowsApps` stay untouched, and styling is injected at launch.
What do the circle and cross insert?
The circle inserts `【反馈：同意】` and the cross `【反馈：不同意】`. With an empty draft and an active send button the message goes out on its own.
What does the environment check do?
`doctor-dream-skin.ps1` only reads: the Codex package, Node.js, configuration, port and PowerShell execution policy.
How do I get the old look back?
Run the restore script with `-RestoreBaseTheme` on Windows or `--restore-base-theme` on macOS.
Which versions does Windows need?
The `OpenAI.Codex` Microsoft Store app, Node.js 22 or newer and PowerShell 5.1 or newer. No administrator rights are required.
