4-agent design-evaluate-iterate harness for distinctive frontend creation that defeats code-anchoring bias and codifies the winning direction into a reusable design system (design-dna.md, tokens.css, and an installable skill template). Use this skill when building web pages, components, or applications where design quality and originality matter — not just functional correctness. Orchestrates separated evaluator, design agent (visual-only, never sees code), and implementation agent with live browser interaction to push past safe AI defaults. Triggers: "create a website", "build a page", "design a frontend", "harness mode", "iterate on design", "evaluate the design", "design quality loop", "overhaul existing UI", "redesign existing site", "redesign this page", "audit this UI", "polish this page", "design review", "slop check", "accessibility audit", "hierarchy review", "ship-ready polish".
