Does it support different Angular FormBuilder styles?

Yes, it recognizes standard FormBuilder, private class fields (#fb), NonNullable groups, and direct FormGroup/UntypedFormGroup instances.

Can it detect custom validators in TypeScript files?

Yes, the skill uses pattern matching to identify custom validator names and complex logic that requires manual error handling implementations.

How does it handle form error messages during migration?

It identifies which validators can use the built-in oneUiFormError directive and which require explicit @if/@else blocks for custom error feedback.

How does the form-extraction skill help with Angular migrations?

It automates the extraction of form definitions and validators from your source code, providing a clear mapping for migrating legacy code to modern One UI patterns.

Extracts and analyzes Angular Reactive Forms to streamline the migration from legacy code to modern UI standards.

This skill facilitates the migration of Angular applications by automating the identification and mapping of Reactive Form components, validators, and error handling patterns. It parses TypeScript and HTML source files to inventory form controls, transition legacy Angular Validators to the newer OneValidators system, and ensure compliance with standardized error display logic. It is an essential tool for developers performing large-scale frontend refactoring who need to maintain form parity while upgrading to a new design system.
