What it does
This project gives AI coding assistants a collection of game-development "skills". Skills are small instruction files that an AI agent loads only when it needs them. They cover game engines such as Godot, Unity, Unreal, Phaser, three.js, Bevy, pygame, LÖVE, Defold and Roblox.
A "router" picks the right skills for you. It looks at your project files to work out which engine you use, reads your request, and loads only the matching skills. For example, asking to add a double jump to a Godot player loads the Godot movement and platformer skills.
Skills cover topics like movement, physics, animation, saving games, menus, multiplayer and publishing. There is also a workflow for making game art that keeps characters, enemies and tiles in a consistent style. Its makers say each skill is written from official documentation and tied to a stated engine version.
Who it's for
People making games with the help of an AI coding assistant such as Claude Code, Cursor, Codex, Copilot or Gemini CLI.
Can I use it without coding?
With some setup. You install it with one command or through Claude Code's plugin commands, then just describe what you want to your AI assistant. New to this? Start here.
Can I run it?
- Cost
- Free, but needs an AI accountThe software is free, but it uses an online AI service (like OpenAI or Anthropic), which usually charges for use.
- Runs on
- Mac, Windows, Linux
- Computer
- An ordinary computer is fine
Try it
- Make sure you already use a supported AI coding assistant, such as Claude Code or Cursor.
- Install the skills with the one-line command from the README, or add it as a Claude Code plugin.
- Describe what you want to build in plain language, and the router loads the right skills.
