+- feat: add custom event dispatch support for tools ([#293](https://github.com/TanStack/ai/pull/293))
+
+  Tools can now emit custom events during execution via `dispatchEvent()`. Custom events are streamed to clients as `custom_event` stream chunks and surfaced through the client chat hook's `onCustomEvent` callback. This enables tools to send progress updates, intermediate results, or any structured data back to the UI during long-running operations.
