Duc01226 Easyplatform Web Design Guidelines

[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 ATTENTION 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:

1. Identify Target — Use provided file/pattern or ask user which components to review
2. Scan Files — Read and Grep target files for violation patterns
3. Check Categories — Accessibility, keyboard nav, forms, animation, performance, touch/mobile, content, dark mode/i18n
4. 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 (content auto-injected by hook — check for [Injected: ...] header before reading)

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

1. Identify target files

   • IF file/pattern argument provided → use it
   • IF not → ask user which files or components to review

2. Scan files using Read and Grep tools

3. 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

4. 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.

Closing Reminders

• IMPORTANT MUST ATTENTION break work into small todo tasks using TaskCreate BEFORE starting
• IMPORTANT MUST ATTENTION search codebase for 3+ similar patterns before creating new code
• IMPORTANT MUST ATTENTION cite file:line evidence for every claim (confidence >80% to act)
• IMPORTANT MUST ATTENTION add a final review todo task to verify work quality
