Picxel is a Python-based Codex skill that converts reference images into pixel-art game assets using GPT for subject interpretation and local algorithms for palette selection, pixel-grid conversion, and cleanup. It targets indie game developers who need consistent 32/64/128px sprites, leveraging the Codex session's image-generation quota without a separate API key. The project's hybrid LLM-guided plus algorithmic pipeline is a pragmatic approach to a niche but real workflow.

Target audience: indie game developers, pixel artists, asset creators
