Hallmark runs 57 checks against generic AI design

Together AI's Nutlope built Hallmark, a design skill that runs 57 checks to keep AI-built interfaces from looking generic, per its GitHub page. The project has picked up 4,758 GitHub stars, a sign developers share the frustration with how Claude Code, Cursor and Codex tend to look.

Hallmark works as a skill inside all three tools. It selects from 20 themes and applies macrostructures based on context. Two different briefs produce different layouts instead of the same template with new copy, per the repo.

Three modes extend past first drafts. hallmark audit scores existing code against the same anti-pattern list. hallmark redesign restructures a page while keeping its content.

hallmark study extracts what the project calls design DNA from existing work, reverse-engineering a style so it can be reapplied elsewhere.

Coming from 20 years of design work, I'd bet on study mode over the other two. Audit and redesign are checklist enforcement, useful but mechanical. Study is trying to extract taste itself, the part of design work I've always found hardest to hand off to a tool. Whether it works will show in whether Hallmark's outputs actually diverge from each other, not only from the old AI look.
