Nutlope/hallmark releases: a design skill that strips the AI look from Claude Code, Cursor, and Codex

Hallmark is a design skill for Claude Code, Cursor, and Codex aimed at rejecting the typical AI-generated look. It offers four verbs: build new UI by default, audit existing code, redesign structure while keeping content, and extract design DNA from a screenshot or URL. The skill picks a macro structure from 21 themes, runs 57 slop-detection gates, and self-reviews before output. Each generated page is self-contained HTML+CSS, with its macro structure noted in comments. For front-end developers using Claude Code, Cursor, or Codex, this means the generated UI is no longer the same template in different colors. Different needs get differently structured pages -- a sourdough app and an extraction API look nothing alike. When a brief carries creative intent the catalog themes can't cover, Hallmark switches to custom mode, designing palette, type, and layout from scratch, still passing the 57 gates.
