The thing I do with sharptools is to set up a generic Tasker profile that grabs all things and attributes. I subscribe to the desired attributes. Then I do something to trigger the device, and have Tasker email all the output variables to me.
From there, I determine what attribute(s) I want to respond to. Then I work it until it sends toasts or alerts upon fulfillment of the context I want. Only at that point do I have it start doing actual tasks.
