It can be a short explanation beside a field, a status message after a background job, a permission-aware prompt, or a sequence that helps a new user complete a real workflow. The engineering challenge is not adding more text to the interface. It is deciding what the user is allowed to know and do, which system state makes the message true, and how the product recovers when that state changes. This guide treats in-app guidance as a small decision system with an explicit contract, accessible presentation, server-side authorization, observable outcomes, and a retirement date."},{"type":"heading","id":"in-app-guidance-operating-model","text":"Start with the operating model","depth":2},{"type":"paragraph","text":"A useful operating model begins with a user task rather than a guidance format.
