Raycast UI Skills

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

When to Apply

Reference these guidelines when:

• Building light-mode interfaces

• Creating Raycast-inspired design systems

• Implementing UIs with Inter font and 4px grid

Colors

• SHOULD use light backgrounds for primary surfaces

• MUST use #DFDFDF as page background (surface-base )

• SHOULD limit color palette to 9 distinct colors

• MUST maintain text contrast ratio of at least 4.5:1 for accessibility

Semantic Tokens

Token HEX RGB Usage

surface-base

#DFDFDF rgb(223,223,223) Page background

surface-raised

#08090B rgb(8,9,11) Cards, modals, raised surfaces

text-primary

#636162 rgb(99,97,98) Headings, body text

text-secondary

#A9A7A8 rgb(169,167,168) Secondary, muted text

text-tertiary

#E99CA8 rgb(233,156,168) Additional text

border-default

#282223 rgb(40,34,35) Subtle borders, dividers

destructive

#E99CA8 rgb(233,156,168) Error states, delete actions

Typography

• MUST use Inter as primary font family

• SHOULD use single font family for consistency

• MUST use 64px / 700 for primary headings

• MUST use 12px / 400 for body text

• MUST limit font weights to: regular, bold, light

• 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 21x)

Font Sizes: 9px, 10px, 11px, 12px, 14px, 15px, 16px, 18px, 64px

Spacing

• MUST use 4px grid for spacing

• SHOULD use spacing from scale: 3px, 5px, 6px, 7px, 8px, 9px, 12px, 56px

• 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: 4px, 6px, 10px, 13px, 18px

• MUST use 1px border width consistently

• 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: 4px, 6px, 10px, 13px, 18px

Layout

• MUST design for 1920px base viewport width

• SHOULD use consistent element widths: 1px, 14px, 1209px, 65px

• 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: 1558px, height: 990px

• Main Content: width: 1196px, height: 945px

Components

Buttons

Variant Background Text Border Height Radius

Ghost transparent #636162 none

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 #08090B background

• List items: use #08090B 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
