# Book App Reviewer Use this skill to review changes in `samples/book-app-web`. ## Review focus 1. Confirm the app remains Vite, React, TypeScript, and Vitest only. 2. Check that tests still pass with `npm test -- --run`. 3. Check that the app builds with `npm run build`. 4. Review accessibility for labels, region names, keyboard-friendly controls, and useful empty states. 5. Review responsive behavior for the filter row, stats cards, and book card grid. 6. Keep changes small enough for a beginner to understand in a course chapter. ## Preferred feedback style - Explain what matters and why. - Avoid style-only comments unless they affect readability, accessibility, or the course goal. - Suggest the smallest safe fix. - If a scenario intentionally fails, confirm it is documented in `samples/app-course-pr-scenarios.md` or `samples/app-course-issues.md`. ## Files usually in scope - `samples/book-app-web/src/App.tsx` - `samples/book-app-web/src/components/*.tsx` - `samples/book-app-web/src/data/books.ts` - `samples/book-app-web/src/styles/app.css` - `samples/book-app-web/src/tests/*.tsx`
