What does apple-design do?

apple-design is a Claude skill that turns ideas from Apple's WWDC design talks, mainly Designing Fluid Interfaces from 2018, into rules for the web. It covers responding on pointer-down, keeping a dragged item glued to the pointer with setPointerCapture, making every animation interruptible, using springs instead of fixed curves, passing release velocity into the next animation, and projecting momentum to choose where a sheet lands. Later sections cover rubber-banding at edges, translucent materials, sound and haptics, reduced motion, and type with optical sizing and tracking. Code samples use CSS and JavaScript. When called with no question, it replies with one line and waits.

When should you use apple-design?

Use it when

  • Building a draggable bottom sheet or swipe gesture
  • Spring animations feel stiff or cannot be interrupted
  • Reviewing reduced-motion support in a web app

Skip it when

  • You need native iOS code in Swift
  • Your interface is mostly static content

How the formula works

Is apple-design safe to install?

Every scanner that checked it passed it. Scanners often miss what other scanners catch, and a skill can change after a scan. Read its source before you install it.
