Mem UI Skills

Opinionated constraints for building Mem-style interfaces with AI agents.

When to Apply

Reference these guidelines when:

  • •Building light-mode interfaces
  • •Creating Mem-inspired design systems
  • •Implementing UIs with Inter font and 4px grid

Colors

  • •SHOULD use light backgrounds for primary surfaces
  • •MUST use #F9F5ED as page background (surface-base)
  • •MUST use #95A3DC for primary actions and focus states (accent)
  • •SHOULD limit color palette to 9 distinct colors
  • •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 86px / 700 for primary headings
  • •MUST use 20px / 400 for body text
  • •MUST limit font weights to: regular, bold, semi_bold
  • •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

Font Families:

  • •Inter (used 13x)

Font Sizes: 13px, 14px, 16px, 18px, 19px, 20px, 86px

Spacing

  • •MUST use 4px grid for spacing
  • •SHOULD use spacing from scale: 1px, 2px, 4px, 5px, 6px, 8px, 13px, 28px
  • •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: 16px, 29px, 32px, 33px, 37px, 39px
  • •SHOULD use 29px+ radius for pill-shaped elements
  • •SHOULD limit border widths to: 1px, 2px, 3px
  • •SHOULD use 37px 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: 16px, 29px, 32px, 33px, 37px, 39px

Layout

  • •MUST design for 1920px base viewport width
  • •SHOULD use consistent element widths: 302px, 304px, 74px
  • •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: 937px
  • •Main Content: width: 1920px, height: 920px
  • •Header: height: 72px
  • •Header: height: 71px

Interactive States

Focus

  • •MUST use 2px outline with accent color (#95A3DC)
  • •MUST use 2px outline-offset
  • •NEVER remove focus indicators

Hover

  • •Buttons (primary): lighten background by 10%
  • •Buttons (secondary): use #EADCC3 background
  • •List items: use #EADCC3 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
