Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
59 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by xnydl on GitHub. Read the source before you install it.

Installation

Install the Codex Dream Skin Studio AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/xnydl/codex-dream-skin/tree/main/macos
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/xnydl/codex-dream-skin.git /tmp/codex-dream-skin
mkdir -p .claude/skills
cp -r /tmp/codex-dream-skin/macos .claude/skills/codex-dream-skin-studio

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Codex Dream Skin Studio in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Codex Dream Skin Studio on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Codex Dream Skin Studio is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Codex Dream Skin Studio

This file is an optional Codex capability entry. The delivery is a complete standalone project; users do not need to install it as a Skill.

Workflow

Run Install Codex Dream Skin.command from the complete project folder.
Run Customize Codex Dream Skin.command, choose an image in Finder, and enter a theme name.
Verify the live result with Verify Codex Dream Skin.command. A pass requires a visible native sidebar and composer, no horizontal overflow, non-interactive decoration, and—on the home route—a continuous wallpaper with live native heading, project controls, and any suggestion cards exposed by the current Codex version.
Restore the official appearance with Restore Codex Dream Skin.command.

Guardrails

Never modify the official .app, app.asar, or its code signature.
Use the official Codex app's signed Node.js runtime only after validating its signature, Team ID, architecture, and minimum version.
Bind CDP to loopback, verify that the listener belongs to Codex, and reject non-Codex renderer targets.
Preserve all native cards, navigation, project selectors, task content, composer controls, and keyboard focus.
Theme images must be UI-free wallpapers. Paint one 16:9 image continuously across the window; keep home expressive and task routes quieter. appearance: auto follows Codex/native or system appearance rather than image brightness.
Keep decoration at pointer-events: none.
Require explicit authorization before restarting an already-running Codex instance.
Stop an injector only when its recorded PID, executable, command line, and start time all match.

Frequently asked questions

What does the Codex Dream Skin Studio AI skill do?

Why use Codex Dream Skin Studio on TypingMind?

Because you install it once and use it with any model. Codex Dream Skin Studio is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Codex Dream Skin Studio in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/xnydl/codex-dream-skin/tree/main/macos. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Codex Dream Skin Studio?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Codex Dream Skin Studio?

As many as you like. As long as a model supports skills, you can use Codex Dream Skin Studio with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Codex Dream Skin Studio AI skill free?

Yes. It is published on GitHub by xnydl under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
