# React / TSX (AgentX)

Canonical: `.github/instructions/react.instructions.md` and
`.github/skills/languages/react/SKILL.md` -- read for full standards.

- Functional components with typed props; custom hooks prefixed `use`.
- useCallback/useMemo/React.memo where it matters; TanStack Query for server

- React Testing Library (test behavior); semantic HTML, alt text, keyboard nav.
