LLMToolCallObserver

public interface LLMToolCallObserver:

LLMToolCallObserver

Observes tool calls performed by an LLMChatSession.

An observer is useful for user interfaces that need to display tool activity while a provider request is still running. The observer must stay lightweight: it is called from the same worker that executes the model request and the actual tool invocation.

class ConsoleToolObserver implements LLMToolCallObserver:
public override beforeToolCall(call as ToolCall) as Void:
print("tool: " + call.name)
