Skill instructions
Forms and Validation in Reactor Reactor forms use a controlled-input pattern — every input has an explicit (value, setter) pair driven by UseState. There is no two-way binding. Validation is layered on top via UseValidationContext and declarative .Validate() modifiers. Controlled prop note: factory call sites keep the plain (value, setter) shape, but the underlying element records use Optional<T. Read element props with .Value / .GetValueOrDefault(...); use Optional<T.Unset only when the WinUI control should own the value. See migration/050-optional-t.md. Quick reference | API | Purpose | |-----|---------| | TextBox(value, setValue) | Controlled text input | | UseValidationContext() | Track validation messages, touched/dirty state | | .Validate(...) | Attach built-in validators to an input | | FormField(input, label: ...) | Wraps input with label, error display, required marker | | new MaskEngine(...) | Masked text input (phone, SSN, etc.) | | InputFormatter.Currency(...) | Format-as-y
