[IMPORTANT] Use TaskCreate to 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:line format, 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.md if 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-motion respected, no transition: 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

[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
