Professional design skills and anti-pattern detection for AI coding assistants

Overview

Impeccable is a professional-grade AI skill and toolset designed to upgrade the frontend design capabilities of AI coding assistants like Cursor, Claude Code, and Gemini CLI. It provides a deep design vocabulary and 18 specialized commands to help AI models move beyond generic, 'plastic' aesthetics. By teaching the AI real design principles across typography, color, layout, and UX writing, it ensures that generated code is production-ready, accessible, and visually distinctive. It also includes an anti-pattern detection engine to identify and fix common AI-generated design mistakes like 'cardocalypse' or overused font families.
