Convex UI Skills

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

When to Apply

Reference these guidelines when:

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

Colors

  • MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 6
  • MUST use #0F0F0F as page background (surface-base)
  • MUST use #214AE8 for primary actions and focus states (accent)
  • SHOULD reduce color palette (currently 31 colors detected)
  • MUST maintain text contrast ratio of at least 4.5:1 for accessibility

Semantic Tokens

warning#F2EAD3rgb(242,234,211)Warning states, cautions

Typography

  • MUST use Inter as primary font family
  • SHOULD use single font family for consistency
  • MUST use 40px / semi_bold for primary headings
  • MUST use 21px / 400 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

Typography Reference

Font Families:

  • Inter (used 95x)

Font Sizes: 4px, 6px, 7px, 8px, 9px, 10px, 11px, 12px, 13px, 14px, 15px, 18px, 20px, 21px, 31px, 40px

Spacing

  • MUST use 4px grid for spacing
  • SHOULD use spacing from scale: 1px, 2px, 3px, 4px, 5px, 6px, 7px, 8px
  • 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: 1px, 3px, 4px, 6px, 7px, 10px, 13px, 15px, 18px, 21px, 50px, 54px
  • SHOULD use 21px+ radius for pill-shaped elements
  • SHOULD limit border widths to: 1px, 2px
  • 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: 1px, 3px, 4px, 6px, 7px, 10px, 13px, 15px, 18px, 21px, 50px, 54px

Layout

  • MUST design for 1920px base viewport width
  • SHOULD use consistent element widths: 12px, 7px, 8px, 2px, 24px
  • 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: 1777px, height: 831px
  • Main Content: width: 1513px, height: 852px

Interactive States

Focus

  • MUST use 2px outline with accent color (#214AE8)
  • MUST use 2px outline-offset
  • NEVER remove focus indicators

Hover

  • Buttons (primary): lighten background by 10%
  • Buttons (secondary): use #262523 background
  • List items: use #262523 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
