About this plugin

Design supports design critique, design-system management, UX writing, accessibility reviews, user research, research synthesis, and developer handoff. It can work from descriptions, screenshots, pasted research materials, or connected design tools such as Figma.

Use it when reviewing an interface, documenting components and tokens, checking WCAG 2.1 AA considerations, preparing implementation guidance, or turning research notes into actionable insights. It is designed primarily for Cowork and also works in Claude Code, with integrations available for teams that want to connect external tools.
