What problem does it solve? AI coding assistants produce visually templated interfaces — purple-gradient heroes, three-column feature grids, Inter-everywhere typography — that audiences instantly recognize as generated. Hallmark encodes a rule set of anti-patterns, macrostructures, themes, and slop-test gates so generated pages and components look deliberately designed rather than defaulted. ## Core Features & Use Cases - Design flow with structural variety: Picks from 21 named macrostructures, 20 catalog themes across four genres (editorial, modern-minimal, atmospheric, playful), and 50 component archetypes, with mandatory diversification rules so consecutive outputs never repeat structure or theme. - Three explicit verbs: hallmark audit scores an existing page against a named anti-pattern list and returns a ranked punch list; hallmark redesign rebuilds visual structure inside existing implementation boundaries; hallmark study extracts design DNA from a screenshot or URL into a diagnosis or portable design.md. - Component-scope mode: Detects single-element briefs (button, card, modal) and emits the component plus an 8-state demo wrapper covering default, hover, focus, active, disabled, loading, error, and success states. - Use Case: Ask the assistant to build a landing page for a SaaS product; Hallmark runs a pre-flight scan of the existing project, asks for audience/use case/tone, picks a non-repeating macrostructure and theme, and emits token-locked, mobile-verified CSS with a stamped critique score. ## Quick Start Ask the assistant to design a landing page for your product and let Hallmark guide the genre, theme, and macrostructure choices.
