# React Component Rules

- Use functional components with explicit return types
- Define props interface directly above the component
- Export components as named exports, never default
- Use Tailwind CSS utility classes exclusively
Roo Code
.roo/rules/*.md
markdown
# Code Standards

## TypeScript
- Enable strict mode in all tsconfig files
- No `any` types — use `unknown` and narrow
- Prefer interfaces over type aliases for object shapes

## React
- Functional components only
- Use custom hooks for shared stateful logic
- Colocate component, styles, and tests

## Git
- Conventional commits (feat:, fix:, chore:, etc.)
- Keep commits atomic and focused
- Squash merge feature branches
