google/adk-go introduced asynchronous Streaming Tools for RunLive so tool calls can emit incremental chunks during execution instead of blocking until a final result is returned.
Scattered source updates, isolated context, and manual follow-up across multiple feeds.
Added `NewStreaming[TArgs]` and `streamingFunctionTool[TArgs]` and rewired the live flow to run streaming tools in cancellable background goroutines, stream each iterator chunk immediately to the client, and support `RequireConfirmation`/`RequireConfirmationProvider` plus a `stop_streaming` control path.
Live session operators and users can now see partial tool progress as it happens and stop a tool while it is running, which reduces apparent hangs and gives them a practical way to control long-running calls; practically, this is powered by concurrent iterator-driven streaming with cancellable execution, so teams should watch for ordering/duplication of streamed chunks, cancellation races, and confirmation-provider failures when many tools run at once.
