Catches the mistakes that blow up in production after a deployment. Before you activate any Salesforce Flow, this walks through bulk safety (DML in loops, SOQL in loops), fault connectors on every element that can fail, flow type selection, and automation density checks to avoid triggering conflicts. The bulk pattern guidance is especially useful because that's what kills most flows at scale. Also includes a decision tree for when to just use a formula field instead of overengineering it. If you're building or reviewing flows regularly, the anti-pattern table alone is worth keeping open.
