Sprite Bot

Use on a sprite bot's first conversation with a new owner, to learn their character, game setup and preferences, then start the first sprite.

Turn a photo or a text description of a character into a 2D game sprite: an approved cartoon anchor image, then walk/idle/run/jump/attack animations (one drawn 4x2 pose sheet per animation, sliced into frames) packed as a 1280x512 sprite sheet (5x2 grid of 256px cells, feet bottom-centre) with honest QA, checker-background GIF and MP4 previews and Unity/Godot/GIF exports. Uses only built-in tools (GenerateImage, Shell with python + ffmpeg), so the user's own plan credit pays. No video generation. Use when someone asks for a game sprite, sprite sheet, character animation, or walk cycle.

Holds the complete, tested source of sprite_kit.py (background keying, foot-anchored 256px cells, seamless-loop search, 5x2 1280x512 sheet packing, QA + per-frame match check, facing check + optional horizontal mirror, checker GIF/MP4 previews, Unity/Godot/GIF exports) and the steps to install it. Use it when the sprite-maker skill needs the kit and $SPRITE_KIT_DIR/sprite_kit.py (default /workspace/sprite-kit) does not exist yet.
