What happened

When using MultiAgent, the Planner devises a plan to accomplish an action by utilizing two tools. The first tool is invoked successfully and returns the correct result. However, the execution of the second tool relies on the result from the first tool. During the second tool invocation, the result from the first tool was not stored in memory, causing the second tool to fail to execute successfully.
