What problem does it solve? AI coding assistants produce interfaces that all look the same — purple-gradient heroes, three-column feature grids, Inter-everywhere typography, and templated nav bars. Hallmark encodes a strict set of anti-slop design rules so generated pages and components look deliberately designed rather than model-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 for audience/use case/tone, then picks one of 21 named macrostructures and a rotating theme catalog to guarantee structural variety across outputs. - Audit, redesign, and study verbs: hallmark audit scores a target 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 report 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, selects a non-repeating macrostructure and theme, and ships a page that passes its slop-test gates including mobile checks at 320/375/414/768 px. ## Quick Start Ask the assistant to design a landing page for your product and let Hallmark run its pre-flight scan and design flow.
