How often are the rules updated?

Updates depend on community pull requests and changes to the source guidelines.

Can I use only specific platforms?

Yes, each platform skill loads independently so you can install or reference only what you need.

Are the rules suitable for production design systems?

They provide strong starting points but should be reviewed against the latest official documentation before final decisions.

What is ehmo/platform-design-skills?

The pack contains separate skill sets for each platform, each built from scraped and condensed official sources including Apple Human Interface Guidelines, Material Design 3, and WCAG 2.2. Every skill includes metadata, rule files with examples, and agent instructions so models can evaluate or create compliant interfaces without hallucinating platform patterns.

Agents activate the relevant skills automatically when they detect platform-specific tasks such as SwiftUI code review or Android Compose audits. The rules focus on navigation, layout, accessibility, gestures, and component usage, giving precise guidance rather than generic advice.

It is intended for developers, designers, and AI users who need consistent, up-to-date platform knowledge integrated directly into their workflow.
