244 pixel-art effects for games: explosions, lightning, fire, ice, portals, spell circles and combo finishers. Every effect is drawn live by a small piece of code, so you can recolor, resize or flip it in the browser. It ships a Claude Code skill that renders frames, checks its own work and keeps adjusting, and it can export transparent sprite sheets for Unity, Godot or video work.
A kit for webcam hand games in the browser: MediaPipe hand tracking, a gesture engine with smoothing so gestures don't flicker, a three.js starter game and a playbook for coding agents. Give your AI the repo link and ask for a game; there is also a Claude Code skill.
An agent skill for Claude Code and Codex that builds a playable 3D action game in the browser from scratch, with AI-generated assets. The demo game 雾锁山门 was made with it.
