Agent prompt

Use Reduced motion for a UI fragment: Reduced motion helps turn motion judgment into actionable design engineering rules. Animate transform and opacity, keep the duration at 420ms, use 28px of visual amplitude, add a 0ms delay, use soft easing (cubic-bezier(0.23, 1, 0.32, 1)), and include a reduced-motion fallback.

Usage
  • Use Reduced motion while reviewing motion risk.
  • Align designers, engineers, or agents around implementation standards.
  • Turn abstract motion principles into executable checks.
Examples
  • Use Reduced motion to evaluate whether a motion pattern affects comprehension, performance, or comfort.
  • Turn Reduced motion into an explicit review criterion during critique.
Review notes
  • Use Reduced motion as review language instead of relying on vague taste.
  • Check whether it serves orientation, feedback, continuity, performance, or comfort.
  • If it adds friction to high-frequency work, reduce or remove the related motion.
