What problem does it solve? Creating generative art that is reproducible across seeds and resolutions is hard: naive sketches use unseeded randomness, break at print sizes, and cannot be browsed as editions. This Skill turns a plain-English description into a deterministic, seedable artwork in one HTML file. ## Core Features & Use Cases - Seeded determinism: Builds on mulberry32/sfc32 PRNGs with named sub-streams for composition, palette, and detail, so every seed reproduces exactly. - Seed browsing and export: Reads a ?seed= query param with a re-seed UI, renders at any size from 400px preview to 4000px print, and supports high-resolution PNG export. - Verification workflow: Runs node tools/check.mjs --seeds 100 to census seeds, checks domain invariants, and writes .harness/verdict.json with readiness status. - Use Case: Ask for a flow-field edition of 100 seeds; the Skill produces sketch/index.html with trait and rarity tables, verifies no blank or duplicate frames across seeds 0-99, and reports reproducibility guarantees. ## Quick Start Create a seedable generative flow-field artwork with an OKLCH palette and a re-seed control, then verify seeds 0 through 99.
