Agent Guidelines

TanStack.com marketing site built with TanStack Start.

Essentials

• Package manager: pnpm
• Run pnpm test at end of task batches (not after every tiny change)
• Don't run builds after every change. This is a visual site; assume changes work unless reported otherwise.
• Typesafety is paramount. Never cast types; fix at source instead. See typescript.md.

Topic Guides

• TypeScript Conventions: Type inference, casting rules, generic naming
• TanStack Patterns: Loaders, server functions, environment shaking
• UI Style Guide: Visual design principles for 2026
