Use when the user asks to build or change frontend code.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Frontend Development Guidelines

Comprehensive guide for modern React development, emphasizing Suspense-based data fetching, lazy loading, proper file organization, and performance optimization.

## When to Use This Skill

- Building new features
- Fetching data with TanStack Query
- Setting up routing with TanStack Router
- Styling components with MUI v7
- Performance optimization
- Organizing frontend code
- TypeScript best practices

---

## Quick Start

### New Component Checklist

Creating a component? Follow this checklist:

- [ ] Use `React.FC<Props>` pattern with TypeScript
- [ ] Lazy load if heavy component: `React.lazy(() => import())`
- [ ] Wrap in `<SuspenseLoader>` for loading states
- [ ] Use `useSuspenseQuery` for data fetching
- [ ] Import aliases: `@/`, `~types`, `~components`, `~features`
- [ ] Styles: Inline if <100 lines, separate file if >100 lines
- [ ] Use `useCallback` for event handlers passed to children
- [ ] Default export at bottom
- [ ] No early returns with loading spinners
- [ ] Use `useMuiSnackbar` for user notifications

How to install

The exact contents, by fingerprint

mdr add tamnguyendinh/anvien/frontend-dev-guidelines@sha256:6e922459392b2dc4

The line at the top of this page pins the label git:20260604.14306d0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
