# Hallmark Hallmark is a design skill for [[Claude Code]], Cursor, and Codex that fights the "AI slop" look: the generic gradient-hero, centered-everything, purple-glow aesthetic that screams "an LLM made this". Built by Hassan El Mghari (Nutlope) at Together AI, MIT licensed. Instead of letting the model freestyle, Hallmark constrains it. It picks a macrostructure for the brief, dresses it in one of twenty themes, then runs the output through 57 slop-test gates before anything ships. Plain HTML and CSS, no framework required. When no catalog theme fits, a custom mode designs from scratch. Four verbs cover the workflow: - **default** — build new UI from a brief - **audit** — score existing code against the anti-patterns, without editing - **redesign** — rebuild the structure while keeping copy and information architecture - **study** — extract design DNA from screenshots or URLs to reuse Install with `npx skills add nutlope/hallmark`. It's a neat example of what [[Claude Code Skills]] are good at: packaging taste and constraints into something reusable, so [[Vibe Coding]] sessions stop producing pages that all look the same. ## References - GitHub: https://github.com/Nutlope/hallmark ## Related - [[Claude Code]] - [[Claude Code Skills]] - [[Vibe Coding]]
