Summary

A specialized Claude/Codex skill for generating clean 2D game sprites and animation atlases using a component-row pipeline. It handles state rows, alpha cleanup, frame extraction, and runtime atlas creation, streamlining sprite sheet production for game developers.

Key features

• Component-row pipeline for organized sprite generation
• State row management for different animation states
• Alpha cleanup for clean sprite edges
• Frame extraction from animations
• Runtime atlas creation for efficient rendering

Use cases

• Generating sprite sheets for 2D platformer games
• Creating animation atlases for RPG characters
• Automating pixel art asset production pipelines
• Building runtime sprite atlases for game engines

Cute demo, useless asset. `sprite-gen` is a Codex/Claude skill that closes that gap. Give it **one base image** and a list of actions — it drives the generation row by row, locks the character's identity, strips the chroma background to real alpha, extracts each pose as a clean transparent frame, and bakes a runtime atlas **with a machine-readable `manifest.json.frame_layout`**. Every sprite above was made this way. And for the last 10% that generation never gets right, there's a **curation webview**: compare frames side by side, reject the broken ones, nudge rotation/scale/position non-destructively, watch the loop live — then bake. The pipeline does the labor; you keep the taste. ```text sprite-request.json → layout guides + prompts → image-
