Spine Animation

Turn existing 2D character art into a rigged, animated, previewable Spine skeleton. The bundled scripts/ do the heavy numerical work (part positioning, JSON assembly, atlas packing, preview rendering); your job is to drive them, judge the visual result, and correct it.

This skill produces Spine-compatible export files (.json + .atlas + .png) and an offline HTML preview. Generating the files does not require a Spine license, and the output loads in the official Spine editor and runtimes (Unity, Godot, Phaser, web). The preview embeds the Spine Web Player runtime, which is covered by the Spine Runtimes License — see Step 6.

Setup

The scripts are plain Python and run from where they live — no copying to a fixed path. Set a convenience variable and install dependencies once per session:
