Generate a modular environment kit — wall pieces, floor tiles, pillars, doors, arches, corners — snap-together meshes sharing one visual style.
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
# Environment Kit — Style-Locked Modular Pieces A kit is a *family* of meshes — wall, floor, door, pillar, corner, arch — that the level designer snaps together to build interiors and exteriors. The skill exists to solve **one specific failure mode**: generating each piece with a fresh prompt produces six pieces that look like they came from six different games. The fix is the **style anchor pattern** — generate one piece first, lock its prompt suffix, and reuse that exact suffix for every subsequent piece. The backing tool is `summer_generate_3d`, called once per piece. A 6-piece kit is six generations and about 5 minutes. Generation uses credits, so confirm scope before starting. ## When to use - "Build me a dungeon kit — walls, floor, door, pillar." - "I need modular wall pieces for a sci-fi corridor." - "Make a tileset for a wooden tavern interior." - "Generate the pieces for a stone temple — I'll assemble the level." - The user wants to build a level out of repeating, snapping pieces. ## When NOT to use - A single hero prop (single chest, single throne) → `prop-model`. …

How to install
mdr add summerengine/summer/environment-kit@sha256:6e79d66c98e57927The 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.
