@mblode/ux-audit

Feature-level UX audit for React/Next.js code, diff-aware by default. Catches what Lighthouse, axe, ESLint, and Storybook miss: state-coverage gaps (missing loading/empty/error), form data loss on validation, double-submit, broken focus management, optimistic UI without rollback, stale async responses, skeleton-induced layout shift, and vague microcopy. 33 modern failure-mode rules plus 30 Laws of UX rules across 12 feature playbooks. Produces a 3-tier ship-readiness verdict (release-blocker / fix-this-sprint / backlog) grouped by surface, with concrete fixes using React 19 APIs (useActionState, useFormStatus, useOptimistic, useTransition, Suspense). Use before merging a frontend PR or when asked "review this PR for UX bugs", "audit this component", "is this checkout/onboarding/dashboard ready?", "what would break in production?", "is this ready to ship?". For agentic-app patterns and trust design, use ax-audit; for page-level audits of rendered UI quality and accessibility, use ui-audit.
