What You Can Do

You can translate motion design vision into comprehensive, developer-ready animation specifications. This skill generates detailed documentation covering timing parameters, easing curves, trigger conditions, state transitions, and edge cases for UI component animations. You'll produce specifications that eliminate guesswork and reduce iteration cycles between design and development teams.

Features

Timing specifications

Generate exact duration, delay, and sequence parameters for multi-stage animations with frame-accurate precision

Easing curve documentation

Define cubic-bezier, spring, or preset easing functions with visual diagrams and technical values

Interaction patterns

Map trigger conditions, user gestures, and state dependencies that initiate animations

Motion timelines

Create detailed choreography for complex animations showing component sequencing and dependencies

Edge case handling

Document fallback behavior, interruption states, and accessibility considerations for animations

Reusable components

Structure specifications for design system implementation across multiple screens and products

Implementation guidance

Include browser compatibility notes, performance considerations, and code hints without generating actual code

Motion guidelines

Establish brand-consistent animation rules and velocity curves for organizational consistency

Example Output

Example 1: Button Hover Animation

code
Component: Primary Button
Trigger: Hover state
Duration: 200ms
Easing: cubic-bezier(0.34, 1.56, 0.64, 1) [Ease Out Back]
Properties:
  - Background: #0066FF → #0052CC
  - Scale: 1 → 1.05
  - Shadow: 0 2px 8px rgba(0,0,0,0.1) → 0 8px 16px rgba(0,0,0,0.2)
Note: Interrupt-safe, handles rapid hover in/out

Example 2: Modal Entrance Sequence

code
Component: Modal Dialog
Trigger: Open action
Sequence:
  [0ms] Overlay fade-in: 200ms, opacity 0→1, easing linear
  [0ms] Modal scale: 300ms, transform scale(0.8)→1, easing cubic-bezier(0.16, 1, 0.3, 1)
  [150ms] Content fade-in: 200ms, opacity 0→1, easing ease-in-out
Total duration: 300ms
Exit: Reverse sequence 250ms on close
