impeccable (design skill)
last updated: Apr 12, 2026
Anthropic created frontend-design, a skill that guides Claude toward better UI design. Impeccable builds on that foundation with deeper expertise and more control.
Every LLM learned from the same generic templates. Without guidance, you get the same predictable mistakes: Inter font, purple gradients, cards nested in cards, gray text on colored backgrounds.
Impeccable fights that bias with:
- An expanded skill with 7 domain-specific reference files (view source)
- 18 steering commands to audit, review, polish, distill, animate, and more
- Curated anti-patterns that explicitly tell the AI what NOT to do
