Hallmark

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

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

Made by Together AI.

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 | Score existing code against the anti-patterns. Punch list, no edits. | | hallmark redesign | Throw out the structure, keep copy + IA + brand, rebuild with a different fingerprint. | | hallmark study | 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.

Bubble Sourdough app · Hum	Distil Extraction API · Cobalt	Cold Snap Record label · Carnival	Cinder AI tool · Lumen
Ferns & Fathom Tea menu · Custom	Hollowback Apiary Honey farm · Garden	Off-Register Print fair · Riso	Press Quaternary Type studio · Custom
Tally SaaS · modern-minimal	Wayfare Travel · atmospheric	NAJM Fashion brand	Hyperlane Dev infrastructure

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.

The Cascadia Nightjar Sleeper-train ticket · Custom	The Mend Assembly Repair-café broadsheet · Custom

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