Hallmark v2 launches: a design-taste skill for Claude Code, Codex and OpenCode
nutlope · x · 2026-10-23
nutlope's team shipped Hallmark v2, a skill that gives coding agents design taste, following 30k stars and 60k installs of the original. It works in Claude Code, Codex, and OpenCode via npx skills add nutlope/hallmark -g.
How it works:
- 48 built-in design themes (editorial, minimal, atmospheric, playful); the agent shortlists 3 per prompt or designs from scratch
- Asks for your real materials (photos, numbers, screenshots) instead of fabricating them
- Layouts are regenerated from scratch each build
- Ships with sloplint: the agent lints the page in a real browser and reviews it — the site claims 26 issues without Hallmark vs 0 with it on the same prompt
