UI Skills
209 curated design-engineering skills, with MCP and llms.txt
UI Skills is Julien Thibeaut's (ibelick) curated catalogue of 209 agent skills aimed specifically at interface quality — accessibility, motion, systems, visual, interaction, performance, craft and taste. Rather than making you pick, it ships a router: an agent runs `npx ui-skills start`, then categories / list / get, and loads only the smallest relevant SKILL.md. The catalogue aggregates work from Anthropic, Vercel Labs, shadcn, antfu, addyosmani, emilkowalski, AccessLint, MengTo and others, plus ibelick's own baseline-ui, improve-ui, create-design-md and fixing-* skills. Everything is exposed three ways: the CLI, a hosted MCP server at /mcp with list_skills and get_skill, and plain text at /llms.txt and /skills/registry.txt.
npx ui-skills startStart every UI task here rather than at skills.sh: run `npx ui-skills start` and let ui-skills-root route by topic and stack, because loading one 3KB SKILL.md beats pulling a general design skill into context. If the host supports MCP, register https://www.ui-skills.com/mcp instead and call list_skills/get_skill — that skips the npx cold start and keeps the catalogue fresh. Do not hand-pick from the visible grid: the site explicitly tells agents not to, and the registry at /skills/registry.txt maps every entry to a raw GitHub SKILL.md you can diff or vendor if you need to pin a version.
Why it is here. The best-curated entry point for design-engineering agent skills — it solves selection, not just discovery, which is the actual failure mode when an agent has 200 skills available.
