Hallmark A design skill for AI coding assistants. Makes the UIs they generate look made, not generated. Hallmark is opinionated, short, and boring on purpose. It encodes a tight set of rules - drawn from the consensus of the anti-AI-slop design field (Anthropic's frontend-design skill, the Claude cookbook on frontend aesthetics, and the 2026 "tactile rebellion" movement) - and refuses to let the model fall back to the defaults every LLM was trained on. The differentiator: Hallmark insists on structural variety, not just visual variety. Two pages by Hallmark for two different briefs should not share the same hero → 3-feature → CTA → footer rhythm. They should feel like different sites, not different colour-swaps of the same template. See references/structure.md. Powered by Together AI. How to use this skill Hallmark has one default behaviour and three explicit verbs.
