add-dart-lint-validation-rule

Custom validation rules in dart_skills_lint are created by extending the SkillRule class. You must register new rules in the central registry to expose them via the CLI for automated quality checks.

Enforcing constraints on skill metadata is done by implementing custom validation classes. This skill provides scaffolding to define rules requiring specific frontmatter fields or mandatory supplementary files.

Testing custom linting rules involves using standardized approaches for in-memory unit testing and file-system integration testing. This ensures validation logic correctly evaluates skill metadata and file structures.

Custom validation rules are needed when you must enforce new constraints on skill frontmatter, such as requiring a specific version field or ensuring mandatory supplementary files are present alongside the skill.

Yes, dart_skills_lint supports registry integration. It guides the registration of newly scaffolded validation rules into the central registry, making them immediately available for CLI exposure and automated testing.
