AI-Generated Review

What is platform-design-skills?

This repo delivers 300+ actionable rules distilled from Apple HIG, Material Design 3, and WCAG 2.2, packaged as agent skills for AI tools like Claude Code, GitHub Copilot, or any agent supporting the format. Install via `npx skills add ehmo/platform-design-skills`, then prompt agents to review SwiftUI views for iOS compliance, Jetpack Compose for Android Material You, or web code for accessibility. It solves the drudgery of cross-referencing massive design docs during code gen, reviews, or refactors across iOS, Android, web, and even visionOS/tvOS.

Why is it gaining traction?

With 177 stars, it's pulling devs hooked on agent skills in VSCode, IntelliJ Copilot, or Anthropic Claude, thanks to platform-spanning coverage no single GitHub agent repo matches. The auto-activation on prompts like "Audit this for HIG" delivers instant feedback on navigation, accessibility, or dynamic colors, cutting manual audits. Early buzz on Reddit and agent GitHub discussions highlights its edge over generic Copilot extensions.

Who should use this?

iOS devs reviewing UIKit/SwiftUI for tab bars or Dynamic Island via Claude agent skills. Android teams checking Material 3 nav in Compose with Copilot. Web devs auditing responsive layouts or WCAG 2.2 compliance in any framework. Cross-platform squads using OpenAI Codex or Microsoft GitHub agents for multi-OS apps.

Verdict

Grab it for agent-driven design audits if you're deep into GitHub Copilot or Claude skills – the rules are sharp and docs solid despite low test coverage. At 177 stars and 1.0% credibility, it's immature; prototype on non-prod code first.
