Key capabilities

  • Structure web UI components
  • Implement responsive layouts for various viewports
  • Apply and extend design tokens for styling
  • Manage local and shared UI state
  • Ensure accessibility standards are met
  • Verify UI across key viewports and user paths

How it works

The skill inventories existing components and tokens, structures semantic HTML, implements mobile-first layouts, manages UI state, applies design tokens, and ensures accessibility.

Inputs & outputs

You give it
A request to build or refine a web UI feature
You get back
Implemented components with consistent patterns and a note on new tokens

When to use frontend-ui-engineering

  • Building a new responsive form
  • Refactoring UI for design system consistency
  • Implementing accessible interactive components

About this skill

Frontend UI Engineering

End-to-end UI implementation: structure, styling, responsive behavior, state, and accessibility. Extends frontend-ui-accessibility with architecture and design-system discipline.

When to use

  • New page, form, or interactive component
  • Refactoring UI for consistency or responsiveness
  • Applying or extending a design system

When not to use

  • Backend-only change
  • Accessibility audit only (use frontend-ui-accessibility)
  • Full visual redesign exploration (consider design consultation workflows)

Workflow

  1. Inventory — existing components, tokens, patterns to reuse
  2. Structure — semantic HTML; split presentational vs container components
  3. Layout — mobile-first breakpoints; avoid fixed widths that break small screens
  4. State — local vs shared; minimize prop drilling; document async/loading/error UI
  5. Styling — tokens (color, spacing, type); no magic numbers scattered
  6. A11y — keyboard, focus, labels, contrast (see frontend-ui-accessibility)
  7. Verify — key viewports; critical user paths; no console errors

Checklist

AreaCheck
ComponentsSingle responsibility; reusable primitives
ResponsiveWorks at 320px and desktop; touch targets adequate
Loading/empty/errorAll three states designed
PerformanceAvoid unnecessary re-renders; lazy-load heavy assets
A11yFocus order, ARIA only when needed, form labels

Output

  • Implemented components with consistent patterns
  • Brief note on new tokens or patterns added to the design system

When not to use it

  • For backend-only changes
  • For accessibility audits only
  • For full visual redesign exploration

Limitations

  • It does not perform full visual redesign exploration
  • It is not for backend-only changes
  • It extends accessibility checks rather than being solely for them

How it compares

This skill provides an end-to-end workflow for UI implementation, integrating architecture and design system discipline, rather than just checking WCAG compliance.
