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-two themes, runs sixty-five 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 by exercising the skill on a different brief. The skill picks differently every time — no two share a macrostructure or theme.
