    Use Cases & Benefits

    • Provides a design skill that generates UI layouts refusing to look AI-generated by applying unique macrostructures and themes.
    • Ensures distinct, non-template-based designs with 57 slop-test gates and self-critique to avoid AI-generated design sloppiness.
    • Use for creating unique, polished web page designs that feel handcrafted rather than AI-generated for branding purposes.
    • Use for auditing and scoring existing UI code against anti-patterns to improve design quality without rewriting code.
    • Use for extracting design DNA from admired screenshots or URLs to replicate style elements without pixel-perfect cloning.

    From the README

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

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

    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.

    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/.
