Step by step
Open the GitHub repo and play the effects in the gallery.
In Claude Code run /plugin marketplace add patch-gg/pixelfx, then /plugin install pixelfx@pixelfx (or copy skills/pixelfx into ~/.claude/skills/).
Ask for what you need, e.g. add a frost nova to my mage's ultimate, or export the fire effects as sprite sheets for Godot.
For a new effect, let it render the contact sheet and run its checks, then ask for changes like make it punchier.
Watch out for
Built for Claude Code. Effects target small pixel resolutions and canvas-style games; for engines you export sprite sheets. Several effects adapt open code from Sprite Fusion and say so at the top of the file; keep that credit if you reuse them.

img2threejs: one image into an editable Three.js 3D model
