Impeccable The vocabulary you didn't know you needed. 1 skill, 20 commands, and curated anti-patterns for impeccable frontend design. > **Quick start:** Visit impeccable.style to download ready-to-use bundles. Why Impeccable? 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) • **20 steering commands** to audit, review, polish, distill, animate, and more • **Curated anti-patterns** that explicitly tell the AI what NOT to do What's Included The Skill: frontend-design A comprehensive design skill with 7 domain-specific references (view skill): | Reference | Covers | |-----------|--------| | typography | Type systems, font pairing, modular scales, OpenType | | color-and-contrast | OKLCH, tinted neutrals, dark mode, accessibility | | spatial-design | Spacing systems, grids, visual hierarchy | | motion-design | Easing curves, staggering, reduced motion | | interaction-design | Forms, focus states, loading patterns | | responsive-design | Mobile-first, fluid design, container queries | | ux-writing | Button labels, error messages, empty states | 20 Commands | Command | What it does | |---------|--------------| | | One-time setup: gather design context, save to config | | | Run technical quality checks (a11y, performance, responsive) | | | UX design review: hierarchy, clarity, emotional resonance | | | Align with design system standards | | | Final pass before shipping | | | Strip to essence | | | Improve unclear UX copy | | | Performance improvements | | | Error handling, i18n, edge cases | | | Add purposeful motion | | | Introduce strategic color | | | Amplify boring designs | | | Tone down overly bold designs | | | Add moments of joy | | | Pull into reusable components | | | Adapt for different devices | | | Design onboarding flows | | | Fix font choices, hierarchy, sizing | | | Fix layout, spacing, visual rhythm | | | Add technically extraordinary effects | Anti-Patterns The skill includes explicit guidance on what to avoid: • Don't use overused fonts (Arial, Inter, system defaults) • Don't use gray text on colored backgrounds • Don't use pure black/gray (always tint) • Don't wrap everything in cards or nest cards inside cards • Don't use bounce/elastic easing (feels dated) See It In Action Visit impeccable.style to see before/after case studies of real projects transformed with Impeccable commands.
