Use when sprite sheets need slicing, stable pivots, texture packing or engine metadata, or when an imported animation jitters, bleeds between cells or loses attachments.
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 atlas Own **packing and import**, not image inventory. [Sprite catalog](../sprite-catalog/SKILL.md) owns required image families; [pixel-animation](../pixel-animation/SKILL.md) owns playback and gameplay frame mapping. Keep the existing family's intent when older callers ask this skill to generate art; route generation before packing. ## Modes | Mode | Output | |---|---| | grid-slice | uniform source cells and explicit empty-cell handling | | trimmed-pack | varying trimmed regions with original geometry preserved | | tileset | tile IDs, margin/separation and terrain metadata | | ui-kit | regions plus nine-slice borders and widget states | Legacy families char-cycle, portrait, projectile, prop, combat-pose, facing, companion, enemy, weapon-overlay, pickup, hud-icon, shadow, vehicle and background remain inventory requests; resolve a packing mode afterwards. VFX generation goes to [vfx-generate](../../assets/vfx-generate/SKILL.md). ## Procedure …

How to install
mdr add jammyfu/open-game-skills/sprite-atlas@sha256:080362cfc46f0267The line at the top of this page pins the label git:20261015.36228cb, 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.
