# Asset Creator — AI-Powered Game Asset Pipeline Generate production-ready pixel art game assets with consistent style, transparent backgrounds, and catalog metadata. Reference files in this skill directory: - `STYLE-GUIDE.md` — Art direction defaults, per-category templates, predefined asset batches - `CATALOG-SCHEMA.md` — manifest.json structure and marketplace metadata ## Pipeline overview ``` 0. STYLE LOCK Meta-prompt one reference asset → extract style DNA (once per project) 1. GENERATE Swap [SUBJECT] in meta prompt → Gemini 3.0 Pro Image 2. BG REMOVE HSL flood fill (Pillow) — magenta + near-white removal 3. NORMALIZE Auto-crop + category-based size normalization 4. CATALOG manifest.json auto-registration with marketplace metadata ``` This pipeline was validated through iterative testing. The meta-prompting approach extracts the "style DNA" from one good asset and replicates it precisely — more consistent than reference images (which the AI may reinterpret) and more token-efficient (264 chars vs 2MB image per call). ## Prerequisites ```bash # Python 3 with Pillow — required for HSL background removal python3 -c "from PIL import Image; print('OK')" # API key — required for AI image generation grep GEMINI_API_KEY .env ``` ImageMagick is NOT required — the pipeline uses pure Python (Pillow) for background removal. ## Usage ``` /asset-creator init — Set up project + extract meta prompt from reference /asset-creato
