## What it does

The skill hands your agent a reference on Apple Human Interface Guidelines for system integrations: Siri, Apple Pay, Tap to Pay, HealthKit, CareKit, ResearchKit, HomeKit, ARKit, Core ML, generative AI, iCloud, Sign in with Apple, SharePlay, CarPlay, Game Center, Wallet, NFC, Maps, Mac Catalyst, VoiceOver and more. It ships as `SKILL.md` plus a `references/` folder with one document per topic — `siri.md`, `apple-pay.md`, `healthkit.md`, `carplay.md` and the rest.

Before asking anything, it checks `.claude/apple-design-context.md` and reuses what is already there. Answers follow a fixed shape: an implementation checklist, required versus optional features for approval, privacy and permission requirements, the user-facing flow from permission prompt to finished task, and testing scenarios.

Handy when you want to check Apple's expectations before submitting a build for review. The skill cross-references `hig-inputs` for input methods and `hig-components-system` for widgets, so those links go nowhere unless you install them too.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add raintree-technology/hig-doctor --skill hig-technologies -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-technologies/SKILL.md

## When to use it
- check Apple HIG requirements before submitting a build for review
- work out a HealthKit permission flow and explain the benefit to the user
- build a checklist for a Sign in with Apple integration
- find out which app types CarPlay actually allows
- plan error handling and fallbacks for Siri

## Example prompts
- What does Apple HIG say about styling an Apple Pay button on checkout?
- Review my HealthKit permission flow against Apple HIG
- Which app types does Apple allow in CarPlay?

  Apple HIG guidance for Apple technology integrations: Siri, Apple Pay, HealthKit,
  HomeKit, ARKit, machine learning, generative AI, iCloud, Sign in with Apple,
  SharePlay, CarPlay, Game Center, in-app purchase, NFC, Wallet, VoiceOver, Maps,
  Mac Catalyst, and more. Use when asked about: "Siri integration", "Apple Pay",
  "HealthKit", "HomeKit", "ARKit", "augmented reality", "machine learning",
  "generative AI", "iCloud sync", "Sign in with Apple", "SharePlay", "CarPlay",
  "in-app purchase", "NFC", "VoiceOver", "Maps", "Mac Catalyst". Also use when
  the user says "how do I integrate Siri," "what are the Apple Pay guidelines,"
  "how should my AR experience work," "how do I use Sign in with Apple," or asks
  about any Apple framework or service integration.
  Cross-references: hig-inputs for input methods, hig-components-system for widgets.

# Apple HIG: Technologies

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

## Key Principles

1. **Apple technologies extend app capabilities through system integration.** Each technology has established user-facing patterns; deviating creates confusion and erodes trust.

2. **Privacy and user control are paramount.** Especially for health, payment, and identity technologies. Request only needed data, explain why, respect choices.

3. **Siri: natural, predictable, recoverable.** Clear conversational intent phrases that complete quickly and confirm results. Support App Shortcuts for proactive suggestions. Handle errors with clear fallbacks.

4. **Payments: transparent and frictionless.** Standard Apple Pay button styles. Never ask for card details when Apple Pay is available. Clearly describe what the user is buying, the price, and whether it's one-time or subscription.

5. **Health data is deeply personal.** Explain the health benefit before requesting access. CareKit tasks should be encouraging. ResearchKit consent flows must be thorough, readable, and respect autonomy.

6. **HomeKit: simple and reliable.** Immediate response when controlling devices. Clear device state. Graceful handling of connectivity issues.

7. **AR: genuine value, not gimmicks.** Use AR when spatial context improves understanding. Guide setup (surface, lighting, space). Provide clear exit back to standard interaction.
