🛑 The Iron Law

NO COMPONENT WITHOUT ACCESSIBILITY AND TEST VERIFICATION

Every component must have semantic HTML, proper ARIA attributes, keyboard navigation, AND a passing test before it ships. "It looks right" is not enough.

🛠️ Tool Guidance

• Context Audit: Use Read to audit existing CSS (Tailwind/Sass) or Component logic (React/Vue).
• Design Alignment: Use Glob to find existing design tokens or utility styles.
• Execution: Use Edit to create or update responsive components.
• Verification: Use Bash to run test suites and linters.

📍 When to Apply

• "Build a new React component for the dashboard."
• "My sidebar is broken on mobile, please fix the layout."
• "Migrate our global state from Prop-drilling to Redux/Zustand."
• "Improve the accessibility (A11y) of our login form."
