Figma UI Skills
Opinionated constraints for building Figma-style interfaces with AI agents.
When to Apply
Reference these guidelines when:
- Building light-mode interfaces
- Creating Figma-inspired design systems
- Implementing UIs with Inter font and 4px grid
Colors
- SHOULD use light backgrounds for primary surfaces
- MUST use
#FFFFFF as page background (surface-base)
- MUST use
#BEBAF6 for primary actions and focus states (accent)
- SHOULD reduce color palette (currently 12 colors detected)
- MUST maintain text contrast ratio of at least 4.5:1 for accessibility

Typography
- MUST use
Inter as primary font family
- SHOULD use single font family for consistency
- MUST use
57px / extra_bold for primary headings
- MUST use
36px / 700 for body text
- SHOULD reduce font weights (currently 5 detected)
- MUST use
text-balance for headings and text-pretty for body text
- SHOULD use
tabular-nums for numeric data
- NEVER modify letter-spacing unless explicitly requested

Spacing
- MUST use 4px grid for spacing
- SHOULD use spacing from scale: 2px, 4px, 5px, 9px, 10px, 11px, 37px, 67px
- SHOULD use 5px as default gap between elements
- NEVER use arbitrary spacing values (use design scale)
- SHOULD maintain consistent padding within containers
Borders
- MUST use border-radius from scale: 3px, 4px
- MUST use 1px border width consistently
- SHOULD use 3px as default border-radius
- NEVER use arbitrary border-radius values (use design scale)
- SHOULD use subtle borders (1px) for element separation
Border Radius Reference
Scale: 3px, 4px
Layout
- MUST design for 1920px base viewport width
- SHOULD use consistent element widths: 36px, 12px, 18px, 79px, 21px
- SHOULD maintain text-heavy layout with clear hierarchy
- NEVER use
h-screen, use h-dvh for full viewport height
- MUST respect
safe-area-inset for fixed elements
- SHOULD use
size-* for square elements instead of w-* + h-*
Detected Layout Patterns
- Main Content: width: 1920px, height: 900px
- Main Content: width: 1602px, height: 617px
- Header: height: 81px

Interactive States
Focus
- MUST use
2px outline with accent color (#BEBAF6)
- MUST use
2px outline-offset
- NEVER remove focus indicators
Hover
- Buttons (primary): lighten background by 10%
- Buttons (secondary): use
#3A28FA background
- List items: use
#3A28FA background
Disabled
- MUST use
opacity: 0.5

cursor: not-allowed
Interaction
- MUST use an
AlertDialog for destructive or irreversible actions
- SHOULD use structural skeletons for loading states
- MUST show errors next to where the action happens
- NEVER block paste in
input or textarea elements
- MUST add an
aria-label to icon-only buttons
Animation
- NEVER add animation unless it is explicitly requested
- MUST animate only compositor props (
transform, opacity)
- NEVER animate layout properties (
width, height, top, left, margin, padding)
- SHOULD use
ease-out on entrance animations
- NEVER exceed
200ms for interaction feedback
- SHOULD respect
prefers-reduced-motion
Performance
- NEVER animate large
blur() or backdrop-filter surfaces
- NEVER apply
will-change outside an active animation
- NEVER use
useEffect for anything that can be expressed as render logic
