Descript UI Skills

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

When to Apply

Reference these guidelines when:

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

Colors

•MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 10
•MUST use #2C0814 as page background (surface-base)
•SHOULD reduce color palette (currently 17 colors detected)
•MUST maintain text contrast ratio of at least 4.5:1 for accessibility

Semantic Tokens

Token	HEX	RGB	Usage
`surface-base`	#2C0814	rgb(44,8,20)	Page background
`surface-raised`	#F9F6F3	rgb(249,246,243)	Cards, modals, raised surfaces
`surface-overlay`	#F2212E	rgb(242,33,46)	Overlays, tooltips, dropdowns
`text-primary`	#484543	rgb(72,69,67)	Headings, body text
`text-secondary`	#747474	rgb(116,116,116)	Secondary, muted text
`text-tertiary`	#F4A9AF	rgb(244,169,175)	Additional text
`border-default`	#ECE3E4	rgb(236,227,228)	Subtle borders, dividers
`destructive`	#F2212E	rgb(242,33,46)	Error states, delete actions
`warning`	#F9F6F3	rgb(249,246,243)	Warning states, cautions

Typography

•MUST use Inter as primary font family
•SHOULD use single font family for consistency
•MUST use 79px / 700 for primary headings
•MUST use 18px / 400 for body text
•MUST limit font weights to: regular, bold, medium
•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

Text Styles

Style	Font	Size	Weight	Color	Count
`heading-1`	Inter	79px	700	#F1E6E3	1
`body`	Inter	18px	400	#BEBEBE	1
`body-secondary`	Inter	17px	500	#3E3337	1
`body-secondary`	Inter	16px	400	#C6ACB4	1
`body-secondary`	Inter	16px	400	#3E3236	1
`caption`	Inter	15px	500	#484543	1
`label`	Inter	15px	400	#A52335	1
`label`	Inter	15px	400	#413438	1
`label`	Inter	14px	400	#747474	1
`label`	Inter	14px	400	#F4A9AF	1

Typography Reference

Font Families:

•Inter (used 15x)

Font Sizes: 13px, 14px, 15px, 16px, 17px, 18px, 79px

Spacing

•MUST use 4px grid for spacing
•SHOULD use spacing from scale: 1px, 5px, 6px, 12px, 30px, 31px, 57px, 68px
•SHOULD use 6px 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, 6px, 7px, 9px, 13px
•SHOULD limit border widths to: 1px, 3px, 4px
•SHOULD use 6px 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, 6px, 7px, 9px, 13px

Layout

•MUST design for 1920px base viewport width
•SHOULD use consistent element widths: 8px, 621px, 620px, 9px, 68px
•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: 1080px
•Main Content: width: 1920px, height: 920px

Components

Buttons

Variant	Background	Text	Border	Height	Radius
Ghost	transparent	#F4A9AF	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 #F9F6F3 background
•List items: use #F9F6F3 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
