Hallmark — A design skill that refuses to look AI-generated
september 2026 ‧ landing page product reference ‧ open in karakeep
Hallmark is a design skill for AI coding assistants like Claude Code, Cursor, and Codex, aimed at producing UI designs that avoid typical AI-generated "slop." It applies a strict anti-slop ruleset, including unique macrostructures, varied themes, and a 57-gate quality check, to build, study, audit, and redesign web pages. Hallmark enforces best practices such as avoiding overused gradients, font pairing, asymmetric layouts, and tailored navigation, ensuring designs look natural and professional. The skill integrates easily via npm and enhances AI outputs with refined, non-generic aesthetics.
A design skill for AI coding assistants. Encodes the anti-slop consensus into one ruleset. Powered by Together AI.
