How does this skill help with React performance?

It provides patterns for the React Compiler, code-splitting with TanStack Router, and asset optimization techniques using Vite to minimize bundle size and improve load times.

Does it support bundle analysis?

Yes, it includes instructions for using rollup-plugin-visualizer with Vite to identify and reduce heavy dependencies in your production build.

Can it help with WCAG compliance?

Yes, it offers guidance on semantic HTML, ARIA roles, keyboard navigation, and testing accessible queries using React Testing Library to meet WCAG AA standards.

What security measures are included?

The skill covers environment variable management to prevent secret leaks, XSS prevention using sanitization, and data validation at API boundaries with Zod.
