UI Designer Skill
Reverse-engineer a design system from a UI reference image — extract tokens, components, and patterns, then output an implementation-ready prompt for v0 / Cursor / frontend-design. By @daymade.

ui-designer is the reverse of generative design tools — instead of
producing a UI, it looks at a UI you already love and decodes it.
The workflow
- Drop a reference image — screenshot, mockup, design file
- Extract the design system — colors as tokens, type scale, spacing, radii, component patterns, micro-interactions
- Output a structured prompt — ready to paste into v0, Cursor,
frontend-design, or any other implementation tool
What it gets right
- Color extraction is semantic (primary, surface, accent), not just hex
- Component-aware — recognizes buttons, cards, navs as patterns, not pixel grids
- Outputs a prompt, not code — keeps the implementation tool in the loop and avoids the “AI-generated React” tell
Where it shines
- Cloning a design vibe without copying source code
- Briefing a v0 / Cursor session — feed it a reference, paste the prompt, get an implementation
- Onboarding to a new design language — quickly understand a product’s visual rules
Composes with
frontend-design— implement the prompt with opinionated tasteweb-artifacts-builder— bundle to single HTMLtheme-factory— apply the extracted tokens consistently
Example prompt
Use ui-designer on this screenshot of Linear's dashboard. Extract the
design system (color tokens, type scale, component patterns) and
produce an implementation prompt I can paste into v0 to build a
similar interface.
