What is Impeccable?

Impeccable is a design skill and toolkit that helps AI coding agents produce better front-end design. It records your product's purpose and audience, gives you commands such as polish, audit, critique and animate, and runs detector rules that flag common signs of generic AI-made interfaces. A CLI and browser extension can run the checks without an AI model. It is free and open source under the Apache 2.0 licence.
