Install Codex skin

Install a Codex skin from files you can inspect.

This is the short path for people searching how to install a Codex skin. Download a real pack, install the helper Skill, stage the files locally, verify the core Codex states, and keep a restore prompt before changing the active appearance.

Install a Codex skin safely. Use $codex-skin-pack-installer, start with caishen-readable, inspect background.png/theme.json/README.md before applying, verify Home / Task / Diff / Composer readability, and tell me exactly how to restore the default Codex theme.
1

Download an inspectable pack

A real Codex skin pack should include background.png, theme.json, README.md, and restore notes. Reject packs that depend on private Codex screenshots, real task names, chat history, or app bundle edits you cannot review.

2

Stage it with the installer Skill

The Skill fetches a known pack from the public release, validates the required files, and leaves the staged package in the local theme library for the active Codex skin manager.

Verify before keeping it

Check Home, Task, Diff, and Composer. If any panel hides text, blocks controls, or makes long sessions tiring, restore the default theme and choose a lower-contrast pack.

Restore the default Codex theme. Remove the active Codex skin override, keep my downloaded skin pack files untouched, restart only if the active theme manager requires it, and confirm that Home, Task, Diff, and Composer are readable again.
Starter packs

Pick one real skin, then inspect the files.

Caishen Readable is the safest default for light mode. The other packs are useful for darker demos, founder workspaces, and operations-style sessions.

Native boundary

This is independent of OpenAI.

The gallery provides public-safe theme files and install prompts. It is not affiliated with OpenAI and does not claim native Codex theme support beyond the user's installed theme tools.

Need generator?

Generate from a starter pack.

If you want a new skin, start from the generator page so the output is still a real pack with background.png, theme.json, README.md, and restore guidance.
