What problem does it solve? Building full-stack React applications requires coordinating routing, server functions, form validation, and AI streaming across multiple libraries. This Skill provides the patterns and APIs for TanStack Start, TanStack Form, and TanStack AI so you can implement these features correctly without digging through documentation. ## Core Features & Use Cases - TanStack Start: Scaffold projects, create file-based routes, write type-safe server functions with Zod validation, and add middleware for auth and logging. - TanStack Form: Build headless forms with sync/async validators, debounced server checks, array fields, and SSR validation via createServerValidate. - TanStack AI: Add streaming chat with useChat hooks, structured output via Zod schemas, and isomorphic tools across OpenAI, Anthropic, Gemini, and Ollama. - Use Case: Create a TanStack Start app with a /posts/$postId route that loads data through a validated server function, renders a type-safe email form with async uniqueness checks, and streams AI chat responses from an API route. ## Quick Start Ask the assistant to scaffold a new TanStack Start project and create a route with a server function and a validated form.
