Impeccable
The design language that makes your AI harness better at frontend design — 1 skill, 23 commands, 45 detector rules
What is it?
Impeccable is a design language and quality layer for AI coding agents. It installs as one skill (`impeccable`) exposing 23 commands, live in-browser variant iteration, and 45 deterministic detector rules for AI-generated frontend design. It evolved from Anthropic's frontend-design skill and works across every major harness — Claude Code, Codex, Cursor, Gemini, opencode, and more. Run `/impeccable init` once to write PRODUCT.md and DESIGN.md, then use commands like polish, audit, critique, distill, animate, bolder, and quieter as a shared design vocabulary with your agent.
