Hallmark
Strongest at checking: audit points out "AI smell" flaws on an existing page, with fixes.
An anti-"AI smell" design skill for Claude Code, Cursor and Codex: 20 themes with very different layouts and 57 checks before delivery.
Overview
Hallmark is an open-source (MIT) design skill by nutlope. Its goal is to turn the agent into a designer: pick the overall layout first, then the theme and details, and avoid repeating the same layout style over and over.
Besides building pages by default, Hallmark has three commands: study (reads the structure of a design you like from a screenshot or URL, without copying pixels), audit (scores an existing page against a list of "AI smell" flaws such as a purple gradient hero, one font for everything, centering everything) and redesign (keeps the content and rebuilds a different framework).
