Description
Hallmark provides design constraints for AI coding assistants to ensure generated interfaces avoid common automated patterns. It helps frontend engineers and designers build greenfield pages that feel intentionally crafted rather than procedurally generated.
The skill enables the extraction of design patterns from URLs or screenshots and allows for auditing existing interfaces against a list of anti-patterns to produce improvement lists.
