A Claude Code skill that encodes a complete Apple Intelligence / Image Playground-style design language — distilled from a production WebGL experience and battle-tested with skill-TDD (baseline agents fail to produce this language; agents with the skill reproduce it faithfully).
What it teaches an agent to build:
- 🫧 Living orbs & soap bubbles — organic wobbling silhouettes (never perfect circles), four independent sliding/pulsing rim lights (never one traveling highlight), glassy near-black interiors, sun-eruption flares
- 🌌 Atmospheres — the 9-stop warm palette, blooms-on-velvet and full-gradient modes, liquid-glass rules, mandatory dither
- 🎬 Motion & choreography — emphasized-decelerate everything (overshoot banned), time-rails vs scroll-rails on shared refs, asymmetric flare envelopes, entrance grammar ("born inside the world"), the ScrollTrigger pin trap
- 🔊 Synthesized UI sound — glassy WebAudio voice recipes, continuous envelope-driven feeds (sound rides the same curves as the light), the mix law
- ✅ Verification craft — motion-proof screenshots, RMS tables, cue-log probes, and a gotcha table where every entry cost a real debugging session
git clone https://github.com/s1gmamale1/Sigma-Designs.git
cp -r Sigma-Designs/sigma-designs ~/.claude/skills/That's it — Claude Code discovers skills in ~/.claude/skills/ automatically.
Then ask for anything in the aesthetic ("a living gradient orb like Apple
Intelligence", "Sigma Designs style hero") and the skill loads itself.
For a single project instead of globally: copy into
