Most automation trouble in the first few months comes from forgetting why something was built a certain way. A lightweight habit helps: for each automation, write down what starts it, what it does in plain words, what it touches (tags, fields, messages), and what to check first if it breaks. Keep that note next to the automation or in one shared place, and update it whenever you change the logic. It takes a couple of minutes per build and saves a lot of guessing when something stops working.
