[IMPORTANT] Use
TaskCreateto break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ask user whether to skip.
Quick Summary
Goal: Review UI code for WCAG 2.2 accessibility, Core Web Vitals performance, and modern web design best practices.
Workflow:
- Identify Target — Use provided file/pattern or ask user which components to review
- Scan Files — Read and Grep target files for violation patterns
- Check Categories — Accessibility, keyboard nav, forms, animation, performance, touch/mobile, content, dark mode/i18n
- Report Findings — Group by file, use
file:lineformat, terse findings, prioritized summary
Key Rules:
- Review-only skill: finds issues, does NOT fix them
- Check categories in priority order (accessibility first)
- Also reference
docs/project-reference/scss-styling-guide.mdif available
Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).
Web Design Guidelines Review
Review UI code for compliance with WCAG 2.2, Core Web Vitals, and modern web design best practices. This is a review-only skill -- it finds issues, not fixes them.
When to Use
- Reviewing UI code for accessibility compliance before release
- Auditing a component or page for WCAG 2.2 violations
- Checking Core Web Vitals performance patterns in code
- Validating responsive design and mobile-friendly patterns
- Pre-PR UI quality gate check
When NOT to Use
- Building UI -- use
frontend-design - Creating design specs -- use
design-spec - Full UX design process -- use
ux-designer - Project SCSS review -- also check
docs/project-reference/scss-styling-guide.md
Prerequisites
- Full guidelines reference:
references/guidelines.md - Project SCSS:
docs/project-reference/scss-styling-guide.md(if available)
Workflow
-
Identify target files
- IF file/pattern argument provided → use it
- IF not → ask user which files or components to review
-
Scan files using Read and Grep tools
-
Check against categories (in priority order):
- Accessibility -- semantic HTML, ARIA, labels, alt text, color contrast, focus indicators
- Keyboard navigation -- tab order, focus trap in modals, escape key handling
- Forms -- labels, validation, error display, autocomplete, paste not blocked
- Animation --
prefers-reduced-motionrespected, notransition: all, GPU-safe properties only - Performance -- image dimensions set, lazy loading, no layout thrashing, virtualization for large lists
- Touch/Mobile -- touch targets >= 44px,
touch-action: manipulation, safe areas - Content -- text overflow handled, empty states, responsive breakpoints
- Dark mode / i18n --
color-scheme, logical CSS properties,Intl.*formatters
-
Report findings in output format below
Output Format
Group by file. Use file:line format. Terse findings. No preamble.
## src/components/Button.tsx
src/components/Button.tsx:42 - icon button missing aria-label
src/components/Button.tsx:55 - animation missing prefers-reduced-motion check
src/components/Button.tsx:67 - transition: all -> list specific properties
src/components/Button.tsx:89 - div with onClick -> use <button>
## src/components/Modal.tsx
src/components/Modal.tsx:12 - missing overscroll-behavior: contain
src/components/Modal.tsx:78 - no focus trap for modal dialog
## src/components/Card.tsx
[check] No issues found
## Summary
- 4 accessibility issues
- 2 performance issues
- 1 UX issue
- Priority: Fix accessibility issues first (WCAG compliance)
Examples
Example 1: Accessibility review
Input: "Review the user profile component for accessibility"
Action: Read component file, check for semantic HTML, ARIA attributes, label associations, color contrast patterns, keyboard navigation, focus indicators. Report each violation with file:line.
Example 2: Visual polish review
Input: "Check the dashboard page for design best practices"
Action: Scan for animation performance (no transition: all), image optimization (dimensions, lazy loading), responsive patterns (breakpoints, safe areas), typography (line height, max-width), empty states handling. Report categorized findings.

IMPORTANT Task Planning Notes (MUST FOLLOW)
- Always plan and break work into many small todo tasks
- Always add a final review todo task to verify work quality and identify fixes/enhancements
