+# Unsend Project Guidelines
+
+## Commands
+- **Build**: `pnpm build` (specific: `pnpm build:web`, `pnpm build:editor`)
+- **Lint**: `pnpm lint`
+- **Dev**: `pnpm dev` (or `pnpm d` for setup + dev)
+- **DB**: `pnpm db:migrate-dev`, `pnpm db:studio`, `pnpm db:push`
+- **Test**: Run single test with `pnpm test --filter=web -- -t "test name"`
+- **Format**: `pnpm format`
+
+## Code Style
+- **Formatting**: Prettier with tailwind plugin
+- **Imports**: Group by source (internal/external), alphabetize
+- **TypeScript**: Strong typing, avoid `any`, use Zod for validation
+- **Naming**: camelCase for variables/functions, PascalCase for components/classes
+- **React**: Functional components with hooks, group related hooks
+- **Component Structure**: Props at top, hooks next, helper functions, then JSX
+- **Error Handling**: Use try/catch with specific error types
+- **API**: Use tRPC for internal, Hono for public API endpoints
+
+Follow Vercel style guides with strict TypeScript. Be thoughtful, write readable code over premature optimization.
