Claude Pxl is a command-line tool that creates pixel art from compact JavaScript and TypeScript code files. It outputs PNGs, sprite sheets with JSON, animated GIFs, and a live browser viewer that replays the painting process step by step as files are saved. The tool is built for both human creators and AI agents, shipping as a ready-made agent skill with editor completion support via type definitions. It includes a domain-specific language featuring color palettes, text grid sprites, geometric primitives, brushes, scene layers, and animation frames. It requires Node and runs without external runtime dependencies or build steps, supporting optional lighting effects and detailed error reporting with file, line, and column references.
