How to Install Codex Skins (Desktop & CLI): The Complete Guide

Codex skins let you reskin OpenAI Codex Desktop and Codex CLI so the workspace matches your taste — a dark low-light palette for night sessions, a pastel surface for daytime, or a neon look just for fun.

This guide covers every way to install a Codex skin, from the one-copy install prompt to CLI theme managers.

The short version

Most skins on this index install the same way:

1. Pick a skin and open its detail page.
2. Copy the install prompt (or download the theme file, for .codedrobe-theme skins).
3. Paste the prompt into Codex Desktop or run the command in Codex CLI.
4. The theme engine applies the palette immediately — no restart needed on most engines.

That’s it. Skins are configuration, not code, so switching is fast and reversible.

Method 1: Copy-paste install prompt (fastest)

Most Codex skins — especially engine presets from Codex Dream Skin, the open-source injection engine — install from a single natural-language prompt.

On the detail page of any skin, the Install prompt box contains a ready-to-paste instruction like:

Codex, apply the 'Clear Glass' light theme — a clean glassy low-distraction surface for my workspace.

Copy it, open Codex, and paste. The engine reads the prompt and applies the palette, borders and accent colors defined in the theme.

Tip: if the prompt applies a preset, the engine stores it so you can switch back to the default later with one click.

Method 2: Download a theme file (.codedrobe-theme)

Some skins ship as a downloadable .codedrobe-theme file. For these:

1. Click Download .codedrobe-theme on the skin page.
2. Save the file anywhere convenient.
3. Open it from Codex Desktop — supported engines import the theme automatically.

This method is common on galleries like codexskins.org that host ready-made theme files.

Method 3: Install a CLI theme with a command

Codex CLI themes use a different install path. Skins with the tmtheme install format (for example the Bearded Theme Ports) install with one command:

curl -fsSL https://raw.githubusercontent.com/vufly/bearded-theme-ports/master/scripts/install-codex.sh | sh
# then in Codex CLI run:
/theme Tokyo Night

Tools like Codex Themes CLI and Codepilot manage CLI themes for you — validate, preview, apply, roll back, and export matching terminal palettes.

How to switch or revert a skin

• Preset engines (Dream Skin etc.): the engine keeps the default preset — usually a “restore default” button returns your original look.
• CLI: /theme lists installed themes; re-run the command with another name to switch.
• Theme files: re-import a previous .codedrobe-theme or re-run the engine’s default.

Popular skins to start with

• Gothic Void Expedition — the engine’s built-in dark default.
• Clear Glass — a glassy light surface for daytime.
• Monokai Stone — the classic CLI palette.
• Hatsune Miku — blue-green vocaloid energy.
