Sprite Gen

What it does

Sprite Gen provides a full pipeline for turning image-generation outputs into runtime-ready sprite sheets and manifests. It handles run preparation, chroma-key alpha cleanup, connected-component extraction, frame composing, QA previews, and an interactive curation webview for human selection and transforms.

When to use it

Use this skill when you need automated sprite-sheet generation from generative image outputs, to curate image candidate sets side-by-side, or to rebuild and edit existing atlases. It's aimed at game developers and artists producing 2D animation assets.

What's included

• Scripts: prepare_sprite_run.py, extract_sprite_row_frames.py, compose_sprite_atlas.py, preview_animation.py, serve_curation.py, unpack_atlas_run.py, and helpers for QA and export.
• References: detailed workflow docs, gating rules for base-anchor workflow, and QA checklists embedded in SKILL.md.
• Instructions: end-to-end pipeline commands, curation webview usage, and motion QA guidelines.

Compatible agents

Works well with Codex and Claude Code environments that can run Python tooling and launch local webviews; integrates with image-generation backends (kuma:image-gen or similar).
