What problem does it solve? AI coding assistants produce UIs that all look the same — purple-gradient heroes, 3-column feature grids, Inter-everywhere typography, and templated nav/footer shapes. Hallmark encodes an opinionated anti-slop design ruleset so generated pages and components look deliberately designed rather than defaulted. ## Core Features & Use Cases - Design flow for new pages: Runs a pre-flight scan of the existing project (fonts, palette, motion libraries, framework), asks an audience/use-case/tone gate, then picks one of 21 named macrostructures and one of 22 catalog themes with mandatory diversification rules. - Three explicit verbs: hallmark audit scores a target against a named anti-pattern list and returns a ranked punch list; hallmark redesign restructures the visual layer 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 scans the repo, preserves the existing Tailwind tokens, picks a non-repeating macrostructure and theme, and ships token-locked CSS verified at 320/375/414/768px widths. ## Quick Start Ask the assistant to design a landing page for your product and answer or skip the three questions about audience, use case, and tone.
