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

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.

| Verb | What it does |
|---|---|
(default) |
Build new UI. Picks a macrostructure, applies the rule-set, runs the slop test before handing back. |
`hallmark audit <target>` |
Score existing code against the anti-patterns. Punch list, no edits. |
`hallmark redesign <target>` |
Throw out the structure, keep copy + IA + brand, rebuild with a different fingerprint. |
`hallmark study <screenshot | URL>` |
Extract the DNA from a design you admire: macrostructure, type-pairing, colour anchor. Refuses pixel-clones and paid templates. Optionally emits a portable `design.md` for handoff to other AI tools. |

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](https://www.usehallmark.com) or under [ site/_tests/](/Nutlope/hallmark/blob/main/site/_tests).

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](/Nutlope/hallmark/blob/main/skills/hallmark/references/custom-theme.md).
