Gusto UI Skills

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

When to Apply

Reference these guidelines when:

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

Colors

• SHOULD use light backgrounds for primary surfaces
• MUST use #116D6C as page background (surface-base)
• MUST use #116D6C for primary actions and focus states (accent)
• SHOULD reduce color palette (currently 23 colors detected)
• MUST maintain text contrast ratio of at least 4.5:1 for accessibility

Semantic Tokens

Token	HEX	RGB	Usage
surface-base	#116D6C	rgb(17,109,108)	Page background
surface-raised	#FFFFFF	rgb(255,255,255)	Cards, modals, raised surfaces
surface-overlay	#063E82	rgb(6,62,130)	Overlays, tooltips, dropdowns
text-primary	#606060	rgb(96,96,96)	Headings, body text
text-secondary	#717171	rgb(113,113,113)	Secondary, muted text
text-tertiary	#898989	rgb(137,137,137)	Additional text
border-default	#E3ECED	rgb(227,236,237)	Subtle borders, dividers
accent	#116D6C	rgb(17,109,108)	Primary actions, links, focus
destructive	#DA6966	rgb(218,105,102)	Error states, delete actions

Typography

• MUST use Inter as primary font family
• SHOULD use single font family for consistency
• MUST use 51px / extra_bold for primary headings
• MUST use 15px / 400 for body text
• SHOULD reduce font weights (currently 6 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

Text Styles

Style	Font	Size	Weight	Color	Count
heading-1	Inter	51px	extra_bold	#353636	1
text-35px	Inter	35px	700	#E0554C	1
text-32px	Inter	32px	extra_bold	#D62833	1
text-30px	Inter	30px	semi_bold	#343434	1
text-28px	Inter	28px	extra_bold	#FADAD3	1
text-25px	Inter	25px	extra_bold	#2E2E2E	1
text-23px	Inter	23px	semi_bold	#DA6966	1
text-22px	Inter	22px	500	#323232	1
text-18px	Inter	18px	500	#575757	1
text-18px	Inter	18px	400	#5B677E	1

Typography Reference

Font Families:

• Inter (used 80x)

Font Sizes: 6px, 7px, 8px, 9px, 10px, 11px, 12px, 13px, 14px, 15px, 17px, 18px, 22px, 23px, 25px, 28px, 30px, 32px, 35px, 51px

Spacing

• MUST use 4px grid for spacing
• SHOULD use spacing from scale: 1px, 2px, 3px, 4px, 5px, 6px, 7px, 9px
• 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, 7px, 9px, 10px, 15px, 16px, 22px, 23px
• SHOULD use 22px+ radius for pill-shaped elements
• SHOULD limit border widths to: 1px, 2px
• SHOULD use 7px 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, 7px, 9px, 10px, 15px, 16px, 22px, 23px

Layout

• MUST design for 1920px base viewport width
• SHOULD use consistent element widths: 15px, 24px, 23px, 48px, 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: 864px
• Main Content: width: 1920px, height: 789px
• Header: height: 76px
• Header: height: 51px

Components

Buttons

Variant	Background	Text	Border	Height	Radius
Ghost	transparent	#807F7D	none	-	-

Interactive States

Focus

• MUST use 2px outline with accent color (#116D6C)
• MUST use 2px outline-offset
• NEVER remove focus indicators

Hover

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