Use when a 2D character needs cosmetic atlas-slot, skeletal-skin, or palette swaps while gameplay collision, timing, and stats must remain unchanged.
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
# Sprite skin Ask the column: | Column | What swaps | |---|---| | atlas-slot | one region in a sprite sheet | | spine-skin | Spine skin / slot attachment | | palette-swap | colors only | Use with [spine-skeletal](../spine-skeletal/SKILL.md). Do not load a missing `spine-2d` path. ## Rules 1. Skin is paint. Hitbox/hurtbox geometry is owned by `hitbox-hurtbox`; collision filters/layers are owned by `collision-layers`. 2. A paid skin is cosmetic. See game-monetization. No paid i-frames. 3. Atlas pack by draw order. Missing attachment falls back to a published default, not a crash. 4. After swap, re-check socket names (weapon, hand) against model-pipeline / character-rig contracts. 5. Pixel-animation sheets use atlas-slot, not a second skeleton. ## Accept Swap skin in the pause menu: same hitbox, same cancel window. A missing slot shows the default arm, not a hole in the hurtbox.

How to install
mdr add jammyfu/open-game-skills/sprite-skin@sha256:0892668e7433d5a1The line at the top of this page pins the label git:20260913.1acd634, 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.
