AI-authored Spine 2D character parts from one painting: See-through layers assembled into rig-ready PNGs and a weighted-mesh rig spec that spine-rigc compiles and verifies before anything is written.

AI-authored Spine 2D rigging and animation, verified before it is written. rigc compiles a rig spec into Spine 4.3 skeleton data, round-trips it through spine-core and named assertions, and emits nothing that fails. Output imports into the Spine editor. Ships as an agent skill.

Spine skeletal animation rendered as plain DOM — one CSS matrix per slot, no canvas for the rigid tier

Example inputs for spine-parts: generated character paintings and their See-through layer decompositions, fetched by the spine-parts selftest and CI.
