Impeccable

🎯 Design vocabulary at your fingertips: Impeccable bridges the gap between developers and designers by providing commands that encode professional design language — so you can request "more vertical rhythm" or "better visual hierarchy" even if you've never used those terms before.

💡 20 purpose-built commands: From diagnostic tools like /audit and /critique to enhancement commands like /animate, /colorize, and /delight, each command targets a specific aspect of frontend design quality.

🔧 Universal AI harness compatibility: Works seamlessly with Cursor, Claude Code, Gemini CLI, Codex CLI, Copilot, Kiro, and more. One install command auto-detects your environment.

📈 Curated anti-patterns library: Includes design anti-patterns across typography, color, layout, motion, and interaction — teaching your AI assistant what to avoid, like overused fonts or lazy monospace shortcuts.

🚀 Enhanced frontend-design skill: Builds on Anthropic's original frontend-design foundation with deeper expertise in design systems, vertical rhythm, and production-grade polish.

⚡ Instant setup, persistent context: Run /teach-impeccable once to generate a .impeccable.md config that gives all commands access to your project's design context automatically.
