Hallmark
Anti-slop design flow with 58 gates and forced structural variety.
What it is
A design skill for AI coding assistants with one default build flow and three verbs: audit, redesign, and study. It pushes for structural variety so two builds don’t share one page rhythm.
Anti-AI-slop design skill for greenfield pages, audits, redesigns, and design extraction from URLs or screenshots. Use when the user asks to build a new app or landing page, wants to redesign something, invokes Hallmark
Why it matters for design
- Diversification rules force different macrostructures, navs, and footers across consecutive builds.
- Locked tokens ban inline hex or font-family values that bypass the token block.
- Every emit is verified at 320, 375, 414, and 768 pixel widths.
What it covers
- How to use this skill
- Disciplines that hold across every verb
- When the brief is a component, not a page
- Design flow (default)
- Hallmark study
- Output contract and scope
