## What it does

The skill helps agents select appropriate UI controls following Apple Human Interface Guidelines. It details when to pick a toggle over a checkbox, how many options fit into a segmented control, and which virtual keyboard fits an input field.

Before asking questions, the skill checks `.claude/apple-design-context.md` for existing project details. Output recommendations deliver clear control rationale, state commit rules (immediate vs confirmation modal), input validation, and VoiceOver hints.

Keep in mind that combo boxes and token fields are macOS-only, which rules them out for iOS projects.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- choose between pickers and segmented controls
- configure virtual keyboard types for text inputs
- structure form state changes between immediate and modal screens
- add accessibility traits and hints for VoiceOver

## Example prompts
- Picker or segmented control for four shipping options?
- What virtual keyboard type should I set for a promo code field?
- Toggle vs checkbox: how should my modal form apply changes?

# Apple HIG: Selection and Input Controls

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

## Key Principles

1. **Clear current state.** Users must always see what is selected. Toggles show on/off, segmented controls highlight the active segment, pickers display the current selection.

2. **Prefer standard system controls.** Built-in controls provide consistency and accessibility. Custom controls introduce a learning curve and may break assistive features.

3. **Toggles for binary states.** On or off. In Settings-style screens, changes take effect immediately. In modal forms, changes commit on confirmation.

4. **Segmented controls for mutually exclusive options.** 2-5 items, roughly equal importance, short labels.

5. **Sliders for continuous values.** When precise numeric input is not critical. Provide min/max labels or icons for range endpoints.

6. **Pickers for long option lists.** Too many options for a segmented control. Works well for dates, times, structured data.

7. **Steppers for small, precise adjustments.** Increment/decrement in fixed steps. Display current value next to the stepper with reasonable min/max bounds.

8. **Text fields for short, single-line input.** Text views for multi-line. Configure keyboard type to match expected input (email, URL, number).

9. **Combo boxes: text input + selection list.** macOS. Type a value or choose from a predefined list when custom values are valid.

10. **Token fields: discrete values as visual tokens.** macOS. For email recipients, tags, or collections of discrete items.

11. **Gauges and rating indicators display values.** Gauges show a value within a range. Rating indicators show ratings (often stars). Display-only; use interactive variants for input.
