Discord UI Skills

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

When to Apply

Reference these guidelines when:

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

Colors

• SHOULD use light backgrounds for primary surfaces
• MUST use #4548ED as page background (surface-base)
• MUST use #4548ED 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

Semantic Tokens

Token	HEX	RGB	Usage
surface-base	#4548ED	rgb(69,72,237)	Page background
surface-raised	#FEFEFE	rgb(254,254,254)	Cards, modals, raised surfaces
text-primary	#C8D0F9	rgb(200,208,249)	Headings, body text
text-2	#494A4B	rgb(73,74,75)	Additional text
text-tertiary	#36383C	rgb(54,56,60)	Additional text
border-default	#4848E2	rgb(72,72,226)	Subtle borders, dividers
accent	#4548ED	rgb(69,72,237)	Primary actions, links, focus

Typography

• MUST use Inter as primary font family
• SHOULD use single font family for consistency
• MUST use 52px / 700 for primary headings
• MUST use 20px / 400 for body text
• MUST limit font weights to: regular, medium, 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

Text Styles

Style	Font	Size	Weight	Color	Count
heading-1	Inter	52px	700	#F4F4F6	1
body	Inter	20px	400	#C8D0F9	1
body-secondary	Inter	18px	400	#C8C8DF	1
text-17px	Inter	17px	500	#CFCFD1	1
text-15px	Inter	15px	400	#414141	1
text-14px	Inter	14px	400	#494A4B	1
text-14px	Inter	14px	400	#B3B3C2	1
text-14px	Inter	14px	400	#B7B6C4	1
text-14px	Inter	14px	400	#BDBCC9	1
text-14px	Inter	14px	400	#B1B0BC	1

Typography Reference

Font Families:

• Inter (used 16x)

Font Sizes: 11px, 12px, 13px, 14px, 15px, 17px, 18px, 20px, 52px

Spacing

• MUST use 4px grid for spacing
• SHOULD use spacing from scale: 5px, 6px, 13px
• 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: 9px
• MUST use 1px border width consistently
• SHOULD use 9px 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: 9px

Layout

• MUST design for 1920px base viewport width
• SHOULD use consistent element widths: 10px, 11px
• 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: 1034px

Components

Buttons

Variant	Background	Text	Border	Height	Radius
Ghost	transparent	#C8D0F9	none	-	-

Interactive States

Focus

• MUST use 2px outline with accent color (#4548ED)
• MUST use 2px outline-offset
• NEVER remove focus indicators

Hover

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