Agent Guidelines

TanStack.com marketing site built with TanStack Start.

Essentials

• Package manager: pnpm
• Run pnpm test before commits not after every tiny edit
• Don't run builds or tests after every change. This is a visual site; assume changes work unless reported otherwise.
• Rely on tsc or your built-in LSP integration (hopefully you have this)
• 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
• Workflow: Build commands, debugging, Playwright
• Analytics: GA4 event taxonomy, funnel definition, custom dimensions
