Ghost UI Skills

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

When to Apply

Reference these guidelines when:

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

Colors

  • •MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 8
  • •MUST use #FFFFFF as page background (surface-base)
  • •SHOULD reduce color palette (currently 18 colors detected)
  • •MUST maintain text contrast ratio of at least 4.5:1 for accessibility

Semantic Tokens

Typography

  • •MUST use Inter as primary font family
  • •SHOULD use single font family for consistency
  • •MUST use 73px / 700 for primary headings
  • •MUST use 26px / 500 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

Font Families:

  • •Inter (used 42x)

Font Sizes: 9px, 10px, 11px, 12px, 13px, 14px, 18px, 23px, 24px, 26px, 73px

Spacing

  • •MUST use 4px grid for spacing
  • •SHOULD use spacing from scale: 1px, 2px, 3px, 4px, 5px, 6px, 7px, 8px
  • •SHOULD use 65px 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, 7px, 13px, 16px
  • •SHOULD limit border widths to: 1px, 6px
  • •SHOULD use 13px 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, 7px, 13px, 16px

Layout

  • •MUST design for 1920px base viewport width
  • •SHOULD use consistent element widths: 260px, 10px, 8px, 13px, 35px
  • •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: 1635px, height: 1080px

Components

Buttons

Ghosttransparent#757678none--

Interactive States

Focus

  • •MUST use 2px outline with accent color (#5E6AD2)
  • •MUST use 2px outline-offset
  • •NEVER remove focus indicators

Hover

  • •Buttons (primary): lighten background by 10%
  • •Buttons (secondary): use #DAE1EC background
  • •List items: use #DAE1EC 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
