Design

Implement comprehensive validation using Zod schemas for type-safe validation on both client and server, with server-side validation as the security boundary (never trust client input). Use this skill when validating user inputs, creating API endpoints that accept data, implementing forms, defining data schemas, validating file uploads, creating validation middleware, implementing Firestore security rules or Supabase RLS, or writing validation rules for any user-provided data. Apply when working on API route handlers, form components with React Hook Form, validation middleware, Zod schema definitions (schemas/*.ts, validation/*.ts), Firestore security rules (firestore.rules), Supabase RLS policies, or any code that accepts external input. This skill ensures server-side validation always (client-side is for UX only), Zod for schema validation with TypeScript type inference (z.infer<typeof schema>), validation middleware factory for Express/Bun APIs, React Hook Form + zodResolver for forms, user-friendly error

Implement accessible user interfaces using semantic HTML, keyboard navigation, proper color contrast, ARIA attributes, alt text, and focus management to ensure all users can interact with the application. Use this skill when creating or modifying React components (.jsx, .tsx), Vue components (.vue), Angular component files, Svelte components, HTML files, template files, or any frontend UI code that renders user interfaces including forms, buttons, links, navigation menus, modals, dialogs, dropdowns, images, or interactive elements. Use this when implementing semantic HTML elements like nav, main, button, header, footer, article, section, form, label, input that convey proper meaning to assistive technologies like screen readers rather than using generic div or span elements, ensuring all interactive elements (buttons, links, form controls, custom widgets) are keyboard accessible with visible focus indicators and proper tab order so users can navigate without a mouse, adding ARIA attributes like aria-label, ar
