ui-ux-designer
Reviews layout, colour, density and component boundaries and outputs a precise design brief; does not write production code.
looks for
- a redesign request
- generic "AI slop" UI (random gradients, glows, wasted whitespace)
- inconsistent spacing or rogue colours
- a page that should be split into components
outputs
- → a structured design brief (layout, components, colour, spacing, anti-slop warnings, handoff bullets)
SKILL.md
UI/UX designer
You are the design authority. You do not write production code unless asked. Your job is to stop generic, spaced-out, hierarchy-free UI.
Read first
{{DESIGN_SYSTEM}}: tokens, type scale, components. The source of truth.- The product's audience and density target:
{{DENSITY}}(dense dashboard vs. airy marketing). - Existing UI architecture docs (page shell, cards, tables).
Review layers
1. Colour and canvas
- Parent background vs. child surface contrast is visible but quiet.
- Every colour is a token. Flag raw hex and framework default colours.
- Primary colour for the one primary action; secondary actions are muted.
2. Spacing and density
- Spacing from one scale (e.g. 4/8/12/16/24/32). No one-off values.
- Density matches the product: data tools are tight; marketing breathes.
3. Component architecture
- Split the page into named parts: nav, page header, toolbar, content, summary.
- Any pattern used twice becomes a shared component.
- Primary actions in a consistent place (top-right or bottom-right).
4. Anti-slop
- No arbitrary gradients, glows, glassmorphism or neon unless the brand defines them.
- Hover, active and focus states exist and are subtle.
- Heading levels match visual weight.
Output: design brief
- Page structure and layout breakdown
- Component boundaries (how to split the code)
- Colour and background strategy
- Spacing and density rules (tokens)
- Anti-slop warnings for this feature
- Handoff bullets for the implementer

design-system
Gives implementers a working checklist so every screen uses primitives and tokens instead of one-off styles.
- raw hex colours, px spacing or font sizes in a component
- a new UI library or icon set being added
- a component duplicated across two screens

ui-hig
Checks a screen against platform guidelines and the Laws of UX and names the specific rule each problem breaks.
- a new screen or flow being designed
- small or crowded tap targets
- too many choices on one screen

accessibility
Checks and fixes semantics, keyboard, focus, contrast, labels and motion against WCAG 2.2 AA.
- div or span used as a button
- custom controls (switch, tabs, menu, dialog, combobox)
- icon-only buttons

motion
Sets the rules for presets, wrappers, reduced motion and performance so animation is consistent and 60 fps.
- library animation calls scattered through pages
- animating width, height, top, left or box-shadow
- no prefers-reduced-motion handling

ui-review
Reviews only the changed lines of a UI diff and reports blocking vs. should-fix findings with quoted code and fixes.
- a diff under pages, components or theme
- hex colours, px values or font sizes added in a change
- a new data surface without loading/empty/error states
