Impeccable

What it is

Think of it as a design system and a senior design reviewer, packed into your AI tool. You type commands like /impeccable critique or /impeccable polish, and it reviews or fixes your page using real design rules for type, spacing, color, and motion. It comes with 24 commands and 61 automatic checks.

Why a designer would care

AI tools learned from the same templates, so everything comes out looking the same: purple gradients, cards inside cards, gray text on color. Impeccable names those habits and steers away from them. You finally get to speak design to your AI: bolder, quieter, distill, polish.

How I'd use it

I'd run /impeccable init once, so it learns what the product is and who it's for. Then I'd run /impeccable critique on any page before I share it, like a crit partner who never gets tired. I'd skip it on tiny throwaway tests, where speed matters more than polish.

Try it in 5 minutes

1. Open Terminal and go to your project folder. New to it? Read Terminal basics first.
2. Run the command below. When it asks, pick the AI tool you use.
3. Open Claude Code or Cursor in that folder and type /impeccable init. Then try /impeccable critique.
