Unity

Unity's official game development plugin. Build, monetize, and operate Unity games with guidance grounded in Unity's documented practices.

Available for Claude Code, Codex, and Grok.

Install

Claude Code

/plugin marketplace add Unity-Technologies/unity-agent-plugin

/plugin install unity@unity-agent-plugin

Codex

codex plugin marketplace add Unity-Technologies/unity-agent-plugin

codex plugin add unity@unity-agent-plugin

Grok

grok plugin install Unity-Technologies/unity-agent-plugin --trust

Grok asks for explicit trust before it installs anything from a repository. This plugin ships skills only — no hooks and no MCP servers.

Verify it worked

Each agent surfaces an installed plugin differently.

Claude Code — type /unity: and the skills appear in the command list. /plugin also shows unity as installed and enabled.

Codex — run codex plugin list:

PLUGIN                    STATUS              VERSION
unity@unity-agent-plugin  installed, enabled  0.1.0-beta

Grok — type / and the skills appear in the slash menu. Grok uses the plain skill name, and switches to the plugin-qualified form (/unity:ui-uitk) when another installed skill shares the same name. grok plugin list shows unity, and grok plugin details unity lists what it provides.

Manual install

If you can't use the marketplace commands, clone the repo and link it into your personal skills directory instead:

git clone https://github.com/Unity-Technologies/unity-agent-plugin.git
ln -s "$(pwd)/unity-agent-plugin" ~/.claude/skills/unity

It loads automatically in every project from your next session onward.

Usage

Once installed, your agent uses the relevant skill automatically when you ask it to do something in your Unity project. For example:

"Add in-app purchases so players can buy a coin pack"

"I want to build a settings screen"

"My pixel art looks blurry and jitters when the camera moves"

"Show rewarded video ads so players can earn coins"

"Create a hexagonal tile palette for my level"

"Chinese characters show up as empty boxes in my TextMeshPro labels"

"Review my ScriptableRendererFeature for Render Graph problems"

In Claude Code and Grok the skills also appear in the slash menu, so you can pick one explicitly instead of describing the task.

Works with

Unity 6+.
