Errors are not accidents, they are paths. When you design the path, you turn frustration into direction. A clear error message with a next step feels like guidance instead of failure.
The strongest error states are specific. They say what happened, why it happened, and what the user can do next. If you can prevent the error entirely, do that, but if you cannot, make the moment useful.
Writing these scripts is part of product design. It is the difference between a system that feels cold and one that feels dependable.
