Generate a pack of 2D game assets from one prompt — tile sheet, UI kit, character pack, or biome set — sliced, classified, and saved as one pack ArtAsset.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# create-asset-sheet — Generate a coherent pack of 2D assets
This skill turns a single prompt into a categorized pack of isolated, named 2D assets ready to drop into a game. Generating assets one by one loses visual coherence between them and leaves you matting backgrounds by hand; one sheet keeps the pack consistent.
**Pipeline:**
1. **Generate a sheet** of N isolated assets in one image-gen call.
2. **Remove the background** so each asset can stand on its own.
3. **Detect, name and classify** each asset in one vision pass (bounding box + snake_case name + category per region).
4. **Crop** each region.
5. **Optionally upscale** any small slice, preserving aspect.
6. **Save** as a single pack ArtAsset with `packFiles: [{url, name, type}]` and `metadata.sliceBboxes`.
Categories the classifier outputs (used to route into downstream pipelines):
`character | terrain | nature | lighting | water | decorative | buildings | ui | vfx`
## When to use
- "Make me a Japanese village tileset."
- "Generate a sci-fi UI kit — buttons, panels, icons."
- "I need 12 fantasy props for a dungeon — chest, torch, skeleton, gold, etc."
- "Give me a character pack: 6 cute monsters."

How to install
mdr add summerengine/summer/create-asset-sheet@sha256:3dd466be063b6d32The line at the top of this page pins the label git:20261010.4ade947, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
