Ticktick UI Skills

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

When to Apply

Reference these guidelines when:

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

Colors

• SHOULD use light backgrounds for primary surfaces
• MUST use #FEFEFE as page background (surface-base)
• MUST use #6E85D9 for primary actions and focus states (accent)
• SHOULD reduce color palette (currently 18 colors detected)
• MUST maintain text contrast ratio of at least 4.5:1 for accessibility

Semantic Tokens

Token	HEX	RGB	Usage
surface-base	#FEFEFE	rgb(254,254,254)	Page background
surface-raised	#D8EDF7	rgb(216,237,247)	Cards, modals, raised surfaces
surface-overlay	#3656F8	rgb(54,86,248)	Overlays, tooltips, dropdowns
text-primary	#CACACA	rgb(202,202,202)	Headings, body text
text-secondary	#8D8D8D	rgb(141,141,141)	Secondary, muted text
text-tertiary	#B7C0DE	rgb(183,192,222)	Additional text
border-default	#9AAFD4	rgb(154,175,212)	Subtle borders, dividers
accent	#6E85D9	rgb(110,133,217)	Primary actions, links, focus

Typography

• MUST use Inter as primary font family
• SHOULD use single font family for consistency
• MUST use 51px / 700 for primary headings
• MUST use 13px / 400 for body text
• SHOULD reduce font weights (currently 4 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	700	#282B2C	1
text-20px	Inter	20px	400	#7D8CD9	1
text-19px	Inter	19px	500	#7C7C7C	1
text-19px	Inter	19px	400	#525F66	1
text-18px	Inter	18px	500	#797979	1
text-16px	Inter	16px	400	#A0A0A0	1
text-16px	Inter	16px	400	#999999	1
text-16px	Inter	16px	400	#6E85D9	1
text-15px	Inter	15px	400	#9A9A9A	1
text-15px	Inter	15px	400	#9C9C9C	1

Typography Reference

Font Families:

• Inter (used 62x)

Font Sizes: 9px, 10px, 11px, 12px, 13px, 14px, 15px, 16px, 18px, 19px, 20px, 51px

Spacing

• MUST use 4px grid for spacing
• SHOULD use spacing from scale: 2px, 4px, 5px, 6px, 9px, 14px, 15px, 20px
• 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: 3px, 16px, 22px, 23px, 25px
• SHOULD use 22px+ radius for pill-shaped elements
• MUST use 1px border width consistently
• 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: 3px, 16px, 22px, 23px, 25px

Layout

• MUST design for 1920px base viewport width
• SHOULD use consistent element widths: 16px, 15px, 14px, 13px, 8px
• 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: 1038px
• Main Content: width: 1001px, height: 583px
• Header: height: 76px

Components

Buttons

Variant	Background	Text	Border	Height	Radius
Ghost	transparent	#C3C2D0	none	-	-

Interactive States

Focus

• MUST use 2px outline with accent color (#6E85D9)
• MUST use 2px outline-offset
• NEVER remove focus indicators

Hover

• Buttons (primary): lighten background by 10%
• Buttons (secondary): use #D8EDF7 background
• List items: use #D8EDF7 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
