README excerpt
# 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`. --- ## Install [code] Re-run any time to update. Or copy `SKILL.md` + `references/` into: - **Claude Code**: `~/.claude/skills/hallmark/` - **Cursor**: `.cursor/rules/hallmark.mdc` (body of `SKILL.md`, no frontmatter) - **Codex**: `~/.codex/skills/hallmark/` (personal) or `.codex/skills/hallmark/` (project-scoped) The rule-set lives in `SKILL.md` and `references/`. Worked examples in `docs/recipes.md` and `docs/study-examples.md`. --- ## Licence MIT. Use it, fork it, ship it.
