 * replaced with values from inputs. Specify placeholders as `{{inputName}}`
 * in the template. The placeholders in the template must match the inputs
 * wired into this node. The node will replace all placeholders with values
 * from the input property bag and pass the result along as the `prompt`
 * output property.
