What it does
This skill gives an AI agent a set of web game development know-how: the game loop, rendering choices (Canvas 2D, WebGL, SVG, CSS), collision detection, physics basics, controls for keyboard, mouse, touch and gamepad, and audio. It also includes starter templates for a breakout-style game, a maze game, a Phaser platformer and a simple 2D engine, plus reference notes on algorithms and 3D web games. Once installed, the agent can follow step-by-step workflows to scaffold a game for you instead of answering from general memory.
Great for
- Hobbyists or students who want a working browser game starting point
- Developers building a small 2D canvas game or prototype from scratch
- Anyone learning how game loops, collision and controls fit together
Skip it if
- Large commercial game projects that need a mature engine such as Unity or Godot; the skill gives basics, not production tooling
- Developers expecting verified, tested code: the templates are illustrative and the skill does not run or test them
- Users who need the referenced files (web-apis.md, techniques.md, etc.) present: the listed file set here does not include all of them, so those references may be missing
Try asking
- “Create a simple breakout game in HTML and JavaScript that I can open in a browser”
- “Build a 2D platformer with gravity and collision using Phaser”
- “Make a maze game that uses phone tilt controls”
- “Explain how to set up a game loop with delta time for my canvas game”

Add it to your agent
Claude Code (all projects)
mkdir -p ~/.claude/skills && unzip game-engine.zip -d ~/.claude/skills/Claude Code / Agent SDK (this project only)
mkdir -p .claude/skills && unzip game-engine.zip -d .claude/skills/Claude apps (web/desktop): Settings → Capabilities → Skills → Upload skill, and choose the ZIP.

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Name the game type and target (desktop browser, mobile, 3D) so the agent picks the right template and renderer
- Ask for a runnable single HTML file first, then iterate on controls and physics
- Test in a browser yourself; the agent cannot verify gameplay feel, and audio needs a user click to start in most browsers
