ai-sdk

AI SDK documentation and guidance for building AI-powered features with Vercel's framework.

- Supports building agents, chatbots, RAG systems, and text generation with structured output and streaming capabilities

- Includes React hooks (useChat, useCompletion) and framework-specific patterns for Next.js, SvelteKit, and other platforms

- Provides type-safe agent consumption with InferAgentUIMessage for end-to-end type safety and local DevTools for debugging
