Impeccable is a comprehensive frontend design skill for Claude Code that moves beyond generic templates to create distinctive, high-fidelity user interfaces. It utilizes a structured 'preflight' checklist—ensuring brand context (PRODUCT.md) and design systems (DESIGN.md) are established before writing code. By enforcing strict design laws like OKLCH color spaces, specific typographic hierarchies, and an explicit ban on common 'AI slop' patterns, Impeccable enables developers to build, critique, and polish web surfaces that feel human-crafted and technically extraordinary.
