Try rain, no rain and an unknown forecast. A workflow uses the information it has to choose the next action. Missing information needs its own path.Useful automation chooses its next action from a result. Switch between rain, no rain and an unknown forecast. The three branches show how to continue when information is available and pause when it is missing.
Local teaching illustration / No AI model call
- Start with Unknown. Read why the decision waits.
- Choose Rain expected in Forecast. Follow the steps to Take an umbrella.
- Choose No rain expected, then Unknown. Explain why missing information should not quietly become no rain.
Unknown forecast: check before deciding whether to take an umbrella.

The idea
A branch is a choice between next steps. Here, expected rain means take an umbrella; no expected rain means leave it. An unknown forecast means check before deciding.You are about to go out. If rain is expected, take an umbrella. If no rain is expected, leave it at home. That simple choice is a branch: the information you have selects what happens next.
You choose the forecast and a written rule follows it. No weather service or AI model runs here. A missing forecast does not mean there will be no rain.This exercise follows a written rule using a forecast you select. It does not check the real weather or ask an AI model. Unknown is a third case: check the forecast before deciding. A missing answer is different from an answer of no. More complex agent workflows need that distinction too.
Take this with you
What changed?
A workflow connects information, a decision and the next action.
Try explaining it.
If a weather service fails, should the program treat that as a forecast of no rain?
Open a possible explanation
No. An unavailable forecast says nothing about whether rain is expected. Report the missing information and check again before choosing a branch.
