Use when a 2D skeletal character needs bind, weighting, layered-track, attachment, or per-actor hitstop playback conventions without moving gameplay timing into animation.

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

# Spine / 2D skeletal

Order: hierarchy → bind → weights → mesh check at bends → layered clips → export.
Bind in setup pose. Weight from the parent bone down. Use the minimum mesh density that preserves the required deformation; do not impose a universal vertex band across characters and camera distances.
Tracks: 0 locomotion, 1 attack overlay, 2 face/VFX. Hitstop sets *that skeleton* timeScale to 0. Never freeze the render ticker.
Pack atlas by draw order to cut material switches. Choose binary or text skeleton data according to the target runtime, debugging needs and build pipeline; do not assume one format is universally smaller or safer.
Wear / cancels still live in `durability-economy` and `action-feel`. The skeleton only plays the pose it is told.

## Accept

Scrub setup, locomotion and overlay tracks while showing the logical gameplay clock. Bind pose and weighted bends remain stable; pausing one skeleton for hitstop does not stop unrelated actors or the render loop. Missing attachments use a declared fallback, and changing an animation blend never creates extra gameplay hit frames.

How to install

The exact contents, by fingerprint
mdr add jammyfu/open-game-skills/spine-skeletal@sha256:0610bb3b1ea94588

The 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.
