What's New

Streaming Tools

This release introduces streaming tools and updates AgentTool and TeamTool to support run_json_stream. The new interface exposes the inner events of tools when calling run_stream of agents and teams. AssistantAgent is also updated to use run_json_stream when the tool supports streaming. So, when using AgentTool or TeamTool with AssistantAgent, you can receive the inner agent's or team's events through the main agent.

To create new streaming tools, subclass autogen_core.tools.BaseStreamTool and implement run_stream. To create new streaming workbench, subclass autogen_core.tools.StreamWorkbench and implement call_tool_stream.

tool_choice parameter for ChatCompletionClient and subclasses

Introduces a new parameter tool_choice to the ChatCompletionClients create and create_stream methods.

This is also the first PR by @copliot-swe-agent!

AssistantAgent's inner tool calling loop

Now you can enable AssistantAgent with an inner tool calling loop by setting the max_tool_iterations parameter through its constructor. The new implementation calls the model and executes tools until (1) the model stops generating tool calls, or (2) max_tool_iterations has been reached. This change simplies the usage of AssistantAgent.
