## What it does

The skill equips coding agents with Apple Human Interface Guidelines tailored to each Apple operating system. Instead of replicating a layout across devices, it guides translation of intents: turning a macOS sidebar into an iOS tab bar, or redesigning layouts for tvOS focus navigation with the Siri Remote.

It checks `.claude/apple-design-context.md` before prompting the user, pulling saved platform targets and UI frameworks directly from your workspace. If no context file exists, the skill clarifies whether the app uses SwiftUI or UIKit/AppKit and verifies the primary usage setting, such as desktop, handheld, or spatial environments.

Responses output HIG citations, platform comparison matrices for navigation and inputs, plus concrete adaptation strategies with recommended system APIs.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add raintree-technology/hig-doctor --skill hig-platforms -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/hig-platforms/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/hig-platforms/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add raintree-technology/hig-doctor --skill hig-platforms -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/hig-platforms/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add raintree-technology/hig-doctor --skill hig-platforms -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/hig-platforms/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install raintree-technology/hig-doctor hig-platforms
```

2. **Manually: put the files in place**
- File: `.github/skills/hig-platforms/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add raintree-technology/hig-doctor --skill hig-platforms -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/raintree-technology/hig-doctor --path skills/hig-platforms
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/hig-platforms/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add raintree-technology/hig-doctor --skill hig-platforms -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/raintree-technology/hig-doctor/tree/HEAD/skills/hig-platforms/SKILL.md

## When to use it
- adapt iPhone navigation patterns for iPadOS multitasking layouts
- structure interaction models for visionOS eye tracking and gestures
- redesign touch layouts into keyboard and menu-driven macOS interfaces
- format glanceable information displays for watchOS complications

## Example prompts
- Should I design differently for iPad vs iPhone for this dashboard?
- What input methods does visionOS use compared to touch on iOS?
- How do I adapt my macOS menu bar and toolbar actions to an iPadOS sidebar?

  Apple Human Interface Guidelines for platform-specific design. Use this skill when the user asks about
  "designing for iOS", "iPad app design", "macOS design", "tvOS", "visionOS", "watchOS", "Apple platform",
  "which platform", platform differences, platform-specific conventions, or multi-platform app design.
  Also use when the user says "should I design differently for iPad vs iPhone", "how does my app work
  on visionOS", "what's different about macOS apps", "porting my app to another platform",
  "universal app design", or "what input methods does this platform use".

# Apple HIG: Platform Design

Check for `.claude/apple-design-context.md` before asking questions. Use existing context and only ask for information not already covered.

## Key Principles

1. **Each platform has a distinct identity.** Do not port designs between platforms. Respect each platform's conventions, interaction models, and user expectations.

2. **iOS: touch-first.** Direct manipulation on a handheld screen. Optimize for one-handed use. Navigation uses tab bars and push/pop stacks.

3. **iPadOS: expanded canvas.** Support Split View, Slide Over, and Stage Manager. Use sidebars and multi-column layouts. Support pointer and keyboard alongside touch.

4. **macOS: pointer and keyboard.** Dense information display is acceptable. Use menu bars, toolbars, and keyboard shortcuts extensively. Windows are resizable with precise control.

5. **tvOS: remote and focus.** Viewed from a distance. Design for the Siri Remote with focus-based navigation. Large text, simple layouts, linear navigation.

6. **visionOS: spatial interaction.** 3D environment using windows, volumes, and spaces. Eye tracking for targeting, indirect gestures for interaction. Respect ergonomic comfort zones.

7. **watchOS: glanceable and brief.** Information consumable at a glance. Brief interactions. Digital Crown, haptics, and complications for timely content.

8. **Games: own paradigm.** Free to define in-game interaction models, but still respect platform conventions for system interactions (notifications, accessibility, controllers).
