Anti-AI-slop design skill for Claude Code, Cursor, and Codex.

Hallmark

A design skill for Claude Code, Cursor, and Codex that refuses to look AI-generated.

Live demo → · twenty themes · four verbs · press T to cycle.

Made by Together AI.

Hallmark picks a macrostructure for the brief, dresses it in one of twenty themes, runs fifty-seven slop-test gates plus a pre-emit self-critique, and refuses the on-distribution defaults every LLM was trained into. Two pages by Hallmark for two different briefs feel like different sites, not colour-swaps of the same template.

Four verbs

Different briefs, different shapes

Each generated from a different brief. The skill picks the theme, structure, and craft to fit each one, not from a template.

Each page is self-contained HTML + CSS, stamped with its macrostructure in the CSS comment. Browse the full set at usehallmark.com or under site/_tests/.

Custom NEW

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. Same 57 slop-test gates, no template underneath.

It stays a quiet branch; vanilla briefs never see it. The protocol lives in custom-theme.md.
