The graph turns a character brief into a reference image and a matching four-quadrant parts sheet. The companion character-sprites skill extracts the parts and bakes 32 transparent animation frames locally. A coding agent used those assets to build Iron Verdict, the playable three-round fighter shown here.

Make it yours

1. Play it. No key. Motion and sound toggles live on the game page.
2. Open the artwork graph and rewrite Character. GLM Flash writes the reference prompt, Muse draws the character, and Muse Edit makes matching parts. Use the companion skill with Node.js and ffmpeg to rig and bake idle, walk, punch and jump frames. Building a game around them requires separate coding work.
3. Inspect the cutout joints and animation frames, then play the game to judge how they move. This prototype uses rigid limbs.
4. The selected source images cost $0.02 combined ($0.01 each for reference and parts). Local baking and playtesting made no further model calls. Your own character spends your NanoGPT balance; the skill has the full run.
