Lattice UI Skills
Opinionated constraints for building Lattice-style interfaces with AI agents.
When to Apply
Reference these guidelines when:
- •Building light-mode interfaces
- •Creating Lattice-inspired design systems
- •Implementing UIs with Inter font and 4px grid
Colors
- •SHOULD use light backgrounds for primary surfaces
- •MUST use
#FEFDFCas page background (surface-base) - •MUST use
#26B177for primary actions and focus states (accent) - •SHOULD reduce color palette (currently 37 colors detected)
- •MUST maintain text contrast ratio of at least 4.5:1 for accessibility

Spacing
- •MUST use 4px grid for spacing
- •SHOULD use spacing from scale: 1px, 2px, 3px, 4px, 5px, 6px, 7px, 8px
- •SHOULD use 1px 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: 0px, 1px, 2px, 3px, 4px, 5px, 6px, 7px, 8px, 9px, 10px, 12px, 13px, 16px, 18px, 19px, 56px, 63px
- •SHOULD use 56px+ radius for pill-shaped elements
- •SHOULD limit border widths to: 1px, 2px, 3px, 4px
- •SHOULD use 4px 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: 0px, 1px, 2px, 3px, 4px, 5px, 6px, 7px, 8px, 9px, 10px, 12px, 13px, 16px, 18px, 19px, 56px, 63px
Layout
- •MUST design for 1920px base viewport width
- •SHOULD use consistent element widths: 6px, 15px, 7px, 14px, 474px
- •NEVER use
h-screen, useh-dvhfor full viewport height - •MUST respect
safe-area-insetfor fixed elements - •SHOULD use
size-*for square elements instead ofw-*+h-*

ease-outon entrance animations - •NEVER exceed
200msfor interaction feedback - •SHOULD respect
prefers-reduced-motion
Performance
- •NEVER animate large
blur()orbackdrop-filtersurfaces - •NEVER apply
will-changeoutside an active animation - •NEVER use
useEffectfor anything that can be expressed as render logic
