game-studio — Claude plugin: browser games in 2D and 3D

Q: How do I install game-studio in Claude?

The plugin lives in the `openai/plugins` repository. Add it as a plugin source in Claude and enable `game-studio` from the list — the exact steps depend on your Claude version.

A Claude and Claude plugin that walks you through building a browser game: prototype, assets, build, playtest.

What game-studio does

game-studio adds guided workflows for browser games to Claude and Claude. Work is split into stages: design, prototype, build, asset pipeline, playtest. There are separate tracks for 2D and for 3D.

The keywords point to a fixed stack: Phaser for 2D, three.js and react-three-fiber for 3D, Rapier for physics, glTF models, sprites, WebGL. So the plugin picks the engine for you instead of leaving that to the model. If your project already runs on something else, expect to translate the advice by hand.

Playtesting is part of the flow. The plugin suggests how to run the build and what to watch for in game behaviour. Handy when you want a playable prototype fast and don't want to spend the first hour wiring up tooling.

What it helps with

get a playable browser game prototype running
pick a 2D or 3D WebGL stack
set up an asset pipeline for sprites and glTF models
wire in physics with Rapier
run a playtest pass and collect what breaks

Example prompts for the agent

Build a 2D Phaser prototype: player, platforms, coin pickup
Set up a react-three-fiber scene with a glTF model and Rapier physics
Walk me through playtesting the current build and note what breaks

What does game-studio do?

It guides browser game development in stages: design, prototype, build, assets, playtest. Separate tracks for 2D and 3D.

What stack does it use for 2D and 3D?

Phaser for 2D, three.js and react-three-fiber for 3D, Rapier for physics, glTF for models. The stack is fixed, so adapting it to another engine takes manual work.
