## Capabilities

- Reviews color, typography, layout, imagery, icons, materials, motion, privacy, and inclusion decisions against Apple HIG foundations.
- Identifies accessibility concerns involving Dynamic Type, VoiceOver, contrast, Reduce Motion, and alternative interaction methods.
- Explains platform differences across iOS, iPadOS, macOS, tvOS, watchOS, and visionOS.
- Recommends semantic system colors, platform fonts, SF Symbols, adaptive layouts, and privacy-aware permission timing.
- Connects related foundations to resolve design tradeoffs, such as color with dark mode and accessibility.
- Produces cited guidance and concrete implementation direction for SwiftUI, UIKit, or AppKit.

## Use Cases

- Review a Mobile Product Flow: Evaluate an iOS or iPadOS flow for hierarchy, adaptive layout, dark mode, motion, and accessible interaction.
- Plan Native Interface Implementation: Translate design requirements into platform-aware guidance for semantic colors, text styles, symbols, and responsive structure.
- Audit an Inclusive Design System: Check shared foundations for contrast, Dynamic Type, VoiceOver, localization, right-to-left behavior, and reduced motion.

## Prompt Templates

### Learn the Foundations

```
Explain the main Apple HIG foundations for a [platform] app. Focus on color, typography, layout, motion, privacy, and accessibility.
```

### Review a Screen

```
Review this [screen or flow] for [platform]. Identify HIG issues, cite relevant foundations, and prioritize practical improvements: [description].
```

### Plan an Implementation

```
Create an implementation plan for this [SwiftUI/UIKit/AppKit] interface: [details]. Include semantic colors, Dynamic Type, VoiceOver behavior, Reduce Motion, and adaptive layout.
```

### Audit a Cross-Platform Experience

```
Audit this cross-platform Apple experience: [details]. Compare platform differences, accessibility risks, privacy prompts, localization, dark mode, and spatial behavior. Rank findings by impact.
```

## Limitations

- Provides design guidance, not runtime testing, legal advice, or App Store approval.
- Recommendations depend on the interface details, target platforms, and constraints supplied by the user.
- Bundled references may not include later Apple changes, so version-sensitive details require current documentation.
- Does not replace accessibility testing with assistive technologies and representative users.

## Best Practices

- Provide target platforms, interface goals, user needs, and technical framework before requesting a review.
- Share relevant screens, flows, brand constraints, and current accessibility behavior.
- Validate recommendations in light, dark, increased contrast, large text, reduced motion, and right-to-left configurations.

## Anti Patterns

- Requesting a generic Apple-like redesign without identifying the target platform or user workflow.
- Treating system colors as fixed values or relying on color alone to communicate meaning.
- Applying identical navigation, layout, and motion behavior across every Apple platform.

## Security Audit

- Summary: All 213 static findings are false positives caused by Apple design prose, image descriptions, Markdown links, paths, or inline code. The skill contains no executable scripts, credential access, network requests, malicious intent, or prompt injection.
