Design guidance for AI coding agents. 1 skill, 23 commands, live browser iteration, and 60 deterministic detector rules for AI-generated frontend design.
Quick start: From your project root, run
npx impeccable install, then run/impeccable initinside your AI coding tool. Full docs: impeccable.style.
Why Impeccable?
Anthropic's frontend-design was the first widely-used design skill for Claude. Impeccable started from there.
Every model trained on the same SaaS templates. Skip the guidance and you get the same handful of tells on every project: Inter for everything, purple-to-blue gradients, cards nested in cards, gray text on colored backgrounds, the rounded-square icon tile above every heading.
Impeccable adds:
- One setup flow.
/impeccable initwritesPRODUCT.mdand offersDESIGN.md, so later commands know the audience, brand/product lane, voice, anti-references, colors, type, and components. - 23 commands. A shared design vocabulary with your AI:
polish,audit,critique,distill,animate,bolder,quieter, and more. - 60 deterministic detector rules plus LLM-only critique checks. The CLI and browser extension run the deterministic rules with no LLM and no API key.
