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. | |

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 or under 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.
