UX/UI Agent Skills, shortened to XIAS, is a design-system knowledge pack for coding agents from plugin87. The README describes instructions, design tokens, 26 runnable skills and 2,144 design systems, 2,087 of them measured from live sites, plus 52 gates that check what the agent builds. It is a pure instruction and knowledge layer for the agent, with the checks run through a small kit. You install it as a Claude Code plugin, and a demo command copies the rendered examples so you can look before you install. The README points to 56 live example pages with a theme toggle. The licence is MIT and the repository was last pushed on 10 November 2026. It suits teams who want an agent to design to a stated standard and be checked against it. One limit: running the gates needs Node packages and a Chrome browser for Playwright. We have not run it ourselves for this note.
