PIPELINE
Deterministic post
Motion frames are sampled from real generated video. Chroma key, connected components, atlas compose, manifest — deterministic post-processing on Pillow + stdlib only. Determinism on top of AI noise.

From one prompt to
game-ready sprite atlas
Describe a character, pick from 16 base candidates, and idle/walk/attack land as frames sampled from real motion video. Add any custom pose you want. Private beta — clicking Generate auto-joins the waitlist.

PIPELINE OUTPUT
Determinism tames the noise
AI gen → chroma key → connected components → cell-based atlas → manifest. Same input → same result (idempotent).

AGENT
Agent-native skill
Claude Code / Codex are first-class. SKILL.md specifies workflow, output contract, gates. Human or agent, same output.
ENGINE
Manifest = contract
sprite-request.json (input) + manifest.json (output) are the SSoT. Unity AssetImporter / Godot resource / Phaser spritesheet consume the same contract.
