Impeccable
The vocabulary you didn't know you needed. 1 skill, 15 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
- 15 steering commands to audit, polish, simplify, 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:
| 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 |
15 Commands
| Command | What it does |
|---|---|
/audit |
Run quality checks, get severity-rated issues |
/normalize |
Align with design system standards |
/polish |
Final pass before shipping |
/simplify |
Strip to essence |
/clarify |
Improve unclear UX copy |
/optimize |
Performance improvements |
/harden |
Error handling, i18n, edge cases |
/animate |
Add purposeful motion |
/colorize |
Introduce strategic color |
/bolder |
Amplify boring designs |
/quieter |
Tone down overly bold designs |
/delight |
Add moments of joy |
/extract |
Pull into reusable components |
/adapt |
Adapt for different devices |
/onboard |
Design onboarding flows |
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)
Installation
Option 1: Download from Website (Recommended)
Visit impeccable.style, download the ZIP for your tool, and extract to your project.
Option 2: Copy from Repository
Cursor:
cp -r dist/cursor/.cursor your-project/
Claude Code:
# Project-specific
cp -r dist/claude-code/.claude your-project/
# Or global (applies to all projects)
cp -r dist/claude-code/.claude/* ~/.claude/
Gemini CLI:
cp dist/gemini/GEMINI*.md your-project/
cp -r dist/gemini/.gemini/* ~/.gemini/
Codex CLI:
cp -r dist/codex/.codex/* ~/.codex/
Usage
Once installed, use commands in your AI coding tool:
/audit # Find issues
/normalize # Fix inconsistencies
/polish # Final cleanup
/simplify # Remove complexity
Most commands accept an optional argument to focus on a specific area:
/audit header
/polish checkout-form
Note: Codex CLI uses a different syntax: /prompts:audit, /prompts:polish, etc.
