Impeccable: frontend design skills for AI coding assistants
Impeccable is an open-source frontend design skill pack that helps AI coding assistants improve interfaces through design references, commands and checks.
Features
Its description covers typography, colour, layout, motion and interaction guidance, along with design review, refinement, documentation and checks. Supported assistants, commands and experimental features depend on current project documentation.
How to use
Read the project documentation and install the skill for your coding assistant. Describe the project’s audience, brand and design requirements, choose an appropriate review or refinement command, and inspect the resulting code and pages.
Considerations
Review the source, permissions and code before installing a third-party skill. Generated or changed interfaces still require human checks for accessibility, responsive behaviour and functionality. Consult current documentation for features, licensing and compatibility.
