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 Semantic Tokens Token HEX RGB Usage surface-base

rgb(77,62,207) Subtle borders, dividers accent

BEBAF6

rgb(190,186,246) Primary actions, links, focus 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 Text Styles Style Font Size Weight Color Count heading-1 Inter 57px extra_bold

Typography Reference

Font Families:

Inter

(used 23x)

Font Sizes:

13px, 14px, 15px, 16px, 17px, 18px, 20px, 22px, 26px, 28px, 30px, 36px, 57px

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-*

background Disabled MUST use opacity: 0.5 MUST use 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
