Impeccable
impeccable.style
A free design skill for AI coding agents — Claude Code, Codex, Cursor and more. Gives your agent the design vocabulary to ship crafted UI instead of AI slop.
What is Impeccable?
Impeccable is an open-source design skill by Paul Bakaus that plugs into AI coding agents like Claude Code, Codex CLI, Cursor and Gemini CLI. It brings a design vocabulary to your agent: a code-level detector with 59 checks that catches AI design clichés (AI beige, italic serif display, side-tab borders, nested cards), commands such as /impeccable polish, typeset, distill and critique, Live Mode for steering a running app, and DESIGN.md / PRODUCT.md files that capture your design system and product context so every feature stays on-brand.
