However, if the user provides values, those will override the Agent's choices.

## Use as Tool Node It can also be used as a Tool Node in a determined workflow scenario. For example, retrieving a list of draft messages before proceeding to the next step.\ In this mode, **Tool Input Arguments must be explicitly defined and filled with values**.\ Unlike the [**Use as Agent Tool**](#use-as-agent-tool) option, there is no Agent to automatically determine the inputs. The user must manually populate the fields, either by entering fixed values or using variables enclosed in double curly brackets `{{ }}`.
