Codex theme generator

Generate a Codex theme from real starter files.

If you searched for a Codex theme generator, start with a real theme pack instead of a fake UI preview. Copy the native import string, install the Skill workflow, fetch Caishen Readable, then ask Codex to generate a new public-safe theme with source files and restore guidance.

Start with a copyable import token

Use a small native theme token when you only need colors and readability. It is faster than installing a full Dream Skin pack and gives the generator workflow a concrete baseline.

Fetch a real generator seed

Caishen Readable is the current best seed because it already has usage signal, lower visual strain, source-visible artwork, theme metadata, README notes, and a portable package.

Ask Codex to remix safely

The prompt forces the output to be useful: source files, readable app states, native import when possible, provenance notes, and a restore path. No private workspace screenshots.

Use $codex-skin-pack-installer as a Codex theme generator workflow. Start from caishen-readable, inspect background.png/theme.json/README.md, then generate a new public-safe Codex theme with readable Home / Task / Diff / Composer states, original or licensed artwork, a native theme import string when possible, downloadable source files, and a restore path. Do not use private Codex screenshots, real sidebars, task names, chats, file paths, or customer data.
Generator checklist

Use licensed or original artwork.

A real Codex theme generator should start from artwork we can distribute, not a private desktop capture. Keep prompts focused on the visual direction, source files, and installable output.

Readability

Protect the left-side reading area.

Place high-detail imagery away from sidebars, task lists, diff panels, and composer controls. The theme only works if everyday Codex text remains readable after the background is applied.

Package

Ship source files and restore guidance.

The finished output should include background.png, theme.json, README.md, a zip download, a copyable install prompt, and a clear rollback path. That is what turns a visual idea into something users can actually try.

Generator seeds

Generate from finished theme directions.

Pick a seed with real files first, then change the artwork, color, contrast, and panel behavior. The output should remain installable, reviewable, and reversible.
