    Interface AgentToolStartedPayload

    Payload of an agent_tool_started stream event. When the Agent delegates to another Agent as a tool, that inner run is reported with the agentTool* family — the shape mirrors the subagent events.

        nodeId: string;
        toolUseId: string;
        agentToolName: string;
        title: string;
        startedAt: number;
        toolArgs: string;
        toolName: string;
        tips: string;
        tipChips: string[];
        isThinking: boolean;
