sprite-gen

Why we included this project

Ask an image model for a sprite sheet and you usually get a character whose face changes every frame, a background that won't key out, and a PNG your engine refuses to load. sprite-gen is a Codex/Claude skill built to close that gap. You give it one base image and a list of actions. It generates the frames row by row, keeps the character's identity locked, strips the chroma background down to real alpha, and extracts each pose as a clean transparent frame. The output is a runtime atlas with a machine-readable manifest of frame rectangles, so your game samples exact regions instead of guessing at a grid. A webview lets you compare frames, reject bad takes, and adjust rotation, scale, and position without destroying the original before you bake the final atlas. If you build 2D or pixel-art games and want deterministic, engine-ready assets rather than demo-quality images, this is worth a look.
