A new design skill called Hallmark, created by Together AI, aims to make AI-generated code look less like typical AI output. It works with coding assistants Claude Code, Cursor, and Codex, forcing them to avoid the default patterns large language models tend to produce.
How it works
Hallmark picks a macrostructure for each brief and dresses it in one of twenty themes. It runs fifty-seven slop-test gates plus a pre-emit self-critique, rejecting the on-distribution defaults every LLM was trained into. Two pages by Hallmark for different briefs feel like different sites, not colour-swaps of the same template.
Each generated page is self-contained HTML + CSS, stamped with its macrostructure in the CSS comment. When a brief carries creative intent that no catalog theme fits, Hallmark switches to Custom and designs the page from scratch: a made-to-measure palette, type, and layout, still using the same 57 slop-test gates but with no template underneath.
Installation and use
Users can add Hallmark via npx: `npx skills add nutlope/hallmark`. Re-run any time to update. The rule-set lives in SKILL.md and references/, with worked examples in docs/recipes.md and docs/study-examples.md. The tool is MIT licensed, free to use, fork, and ship.
