If you're building React chat UIs with Vercel's AI SDK v6, this is the reference you want open. It documents the three core hooks (useChat, useCompletion, useObject), explains the breaking .parts array change from v5, and walks through tool approval workflows for human-in-the-loop scenarios. The real value is the 18 documented error solutions covering stream parsing failures, React Strict Mode closure bugs, and race conditions. Reach for this when you're wiring up streaming completions, debugging why messages aren't rendering correctly, or implementing tool calls that need user confirmation before executing.
