# Hallmark

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

[Live demo →](https://www.usehallmark.com)  ·  twenty-one themes  ·  four verbs  ·  press `T` to cycle.

Made by Together AI.

</p>

Hallmark picks a macrostructure for the brief, dresses it in one of twenty-one 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

| 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. |

## 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.

## Custom <sup>NEW</sup>

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.

<table>
  <tr>
    <td width="50%"><a href="https://www.usehallmark.com/examples/custom-02/"><img src="docs/screenshots/hero-custom-02.jpg" alt="The Cascadia Nightjar sleeper-train ticket hero" /></a></td>
    <td width="50%"><a href="https://www.usehallmark.com/examples/custom-04/"><img src="docs/screenshots/hero-custom-04.jpg" alt="The Mend Assembly repair-café broadsheet hero" /></a></td>
  </tr>
  <tr>
    <td><b>The Cascadia Nightjar</b><br/><sub>Sleeper-train ticket · Custom</sub></td>
    <td><b>The Mend Assembly</b><br/><sub>Repair-café broadsheet · Custom</sub></td>
  </tr>
</table>

It stays a quiet branch; vanilla briefs never see it. The protocol lives in [`custom-theme.md`](skills/hallmark/references/custom-theme.md).
