Impeccable
Open-source design vocabulary and command pack that helps AI coding tools produce more polished frontend work.
What is Impeccable?
Impeccable is a newly launched open-source design vocabulary layer for AI coding tools. It extends Anthropic's frontend-design skill with deeper references for typography, color, spatial design, motion, interaction, responsive design, and UX writing, then adds a set of commands for auditing, polishing, critiquing, and refining UI work. The project is aimed at developers and teams who use AI harnesses like Cursor, Claude Code, Gemini CLI, OpenCode, and similar tools but want more consistent, less generic frontend output.
Best for: Teams improving AI-assisted frontend work · Developers who want reusable design commands · Cross-tool AI coding workflows
