A longer walkthrough for applying your first Codex skin and keeping it reversible.

Before you start

Skins style Codex at the visual layer only, over 127.0.0.1. No app files are modified and your API key is never touched.

Install an engine once

Clone or download a skin engine such as Codex Dream Skin, or use a manager like Codex Skin Manager. This is a one-time setup on your machine.
Find a skin in the index

Browse categories or search by mood and color. Open the skin page to see its description, compatible platforms, and the exact install prompt.
Copy and apply

Click Copy on the install prompt, paste it into Codex Desktop, or run the CLI command. The workspace updates immediately.
Verify and keep the source

Confirm the new look, then bookmark the source link. If Codex updates and a skin breaks, re-run the source restore step to return to stock.

Start with a featured skin — it is the most likely to apply cleanly through the engine's default preset.
Copy the exact prompt text; small edits can change what the engine applies.
Keep the source link handy so you can restore or re-apply after a Codex update.
Use the category and mood filters to narrow 26+ skins to a handful that fit your taste.
