npx mdskills install ehmo/androidComprehensive Material Design 3 guidelines with clear rules, semantic color usage, and adaptive layout patterns
A collection of agent skills for building and evaluating apps across every major platform. Each skill encodes the official design guidelines — from Apple's Human Interface Guidelines to Google's Material Design to web standards — into actionable rules AI agents can apply during code generation, review, and refactoring.
Built by scraping the Apple Human Interface Guidelines (a compiled PDF version is included in this repo) and distilling it — along with Material Design 3 and WCAG 2.2 — into succinct but exhaustive skill files. Use them to evaluate, improve, or create your designs.
