+# SwiftUI Agent Skill
+
+**Author:** [Paul Hudson (@twostraws)](https://github.com/twostraws)  
+**Repository:** https://github.com/twostraws/SwiftUI-Agent-Skill  
+**License:** MIT  
+**Targets:** iOS 26+ · Swift 6.2+  
+
+---
+
+A comprehensive SwiftUI code-review agent skill for Claude Code, Codex, Gemini,
+Cursor, and other AI coding assistants. Built on thousands of hours of real-world
+SwiftUI experience, this skill directly targets the mistakes LLMs *actually* make
+when writing SwiftUI code.
+
+## What It Reviews
+
+| Area | Examples |
+|---|---|
+| **Deprecated API** | `foregroundColor()` → `foregroundStyle()`, legacy `NavigationView` |
+| **Views & Modifiers** | Redundant modifiers, animation API correctness |
+| **Data Flow** | `@State`, `@Binding`, `@Observable`, `@StateObject` / `@ObservedObject` |
+| **Navigation** | `NavigationStack` / `NavigationSplitView` patterns |
+| **Design (HIG)** | Apple Human Interface Guidelines compliance |
+| **Accessibility** | VoiceOver labels, Dynamic Type, Reduce Motion |
+| **Performance** | Expensive view-body computations, `task(id:)` usage |
+| **Swift** | Modern Concurrency, Swift 6.2+ idioms |
+| **Hygiene** | One type per file, naming, clean compilation |
+
+## Usage
+
+**Claude Code:**
+```
+/swiftui-pro
+/swiftui-pro Check for deprecated API
+/swiftui-pro Focus on accessibility
+```
+
+**Codex:**
+```
+$swiftui-pro
+$swiftui-pro Focus on performance
+```
+
+**Install via npx:**
+```bash
+npx skills add https://github.com/twostraws/swiftui-agent-skill --skill swiftui-pro
+```
+
+**Claude Code Marketplace:**
+```
+/plugin marketplace add twostraws/SwiftUI-Agent-Skill
+/plugin install swiftui-pro@swiftui-agent-skill
+```
+
+## Output Format
+
+Findings are organised by file. Each issue includes:
+1. File name and relevant line(s)
+2. The rule being violated
+3. A before/after code fix
+
+The review ends with a prioritised summary of the most impactful changes to make first.
