About

UI Skillbook is a curated field guide of reusable UI skills, rules, patterns, and agent instructions for building better interfaces. It's built for developers browsing manually, AI coding agents consuming structured skills, and designers looking for implementation guidance.

The question it answers is: “I'm building this UI. What skill should my agent know before touching the code?” Not: here are five thousand random prompts.

Curation

Every published skill has a concrete purpose, gives a usable instruction, doesn't duplicate another skill already in the book, preserves attribution, links its source, and states its license. Skills that don't meet that bar don't get published.

Open source content

Skill content is stored as plain markdown with a predictable schema — see any skill's “View raw” link. GitHub is the source of truth; the site indexes it at build time.

What's next

The website comes first. A CLI and MCP server for pulling skills directly into an agent session are planned once the core library and usage patterns prove out.
