# apple-ui-skills

Hands the agent a fixed set of Apple-style UI rules: light surfaces, Inter, a 4px grid. Useful when you want a predictable look without tweaking every value by hand.

## What it does

The skill loads as constraints the agent follows while generating an interface. Colors come with HEX values: `#FFFFFF` for the page background, `#155BD0` for primary actions and focus, plus separate tokens for text and borders. Text contrast stays at 4.5:1 or better.

Typography is pinned to Inter: headings at 51px weight 700, body at 27px weight 500. Headings should use `text-balance`, numbers `tabular-nums`, and letter-spacing stays untouched. Spacing follows a 4px grid, radii come from a 21px scale, border width is fixed at 1px.

Separate sections cover states and motion. Focus indicators must stay visible: a 2px outline in the accent color with a 2px offset. Animation is off unless you ask for it, and feedback stays under 200ms. Full-height layouts should use `h-dvh`, not `h-screen`. Worth knowing: the rules are strict, so on a project with its own design system they will fight the tokens already in place.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ihlamury/design-skills --skill apple-ui-skills -a claude-code
```
```bash
npx skills add ihlamury/design-skills --skill apple -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ihlamury/design-skills --skill apple -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ihlamury/design-skills --skill apple -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ihlamury/design-skills apple
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ihlamury/design-skills --skill apple -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ihlamury/design-skills --path skills/apple
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ihlamury/design-skills --skill apple -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/ihlamury/design-skills/tree/HEAD/skills/apple/SKILL.md

## When to use it
- build a light Apple-style interface without hand-picking colors
- keep one 4px spacing grid across components
- pick sizes and weights for Inter
- keep focus indicators visible on buttons and links
- limit animation to compositor properties

## Example prompts
- Build a settings page following apple-ui-skills: light background, Inter, 4px grid
- Rewrite this component against the Apple design system from the skill and check text contrast
- Run my CSS through apple-ui-skills and list the spacing and radius violations

# Apple UI Skills

Opinionated constraints for building Apple-style interfaces with AI agents.

## When to Apply

Reference these guidelines when:
- Building light-mode interfaces
- Creating Apple-inspired design systems
- Implementing UIs with Inter font and 4px grid

## Colors

- SHOULD use light backgrounds for primary surfaces
- MUST use `#FFFFFF` as page background (`surface-base`)
- MUST use `#155BD0` for primary actions and focus states (`accent`)
- SHOULD limit color palette to 10 distinct colors
- MUST maintain text contrast ratio of at least 4.5:1 for accessibility

### Semantic Tokens

| Token | HEX | RGB | Usage |
|-------|-----|-----|-------|
| `surface-base` | #FFFFFF | rgb(255,255,255) | Page background |
| `surface-raised` | #0858DC | rgb(8,88,220) | Cards, modals, raised surfaces |
| `text-primary` | #808080 | rgb(128,128,128) | Headings, body text |
| `text-secondary` | #6D89B5 | rgb(109,137,181) | Secondary, muted text |
| `text-tertiary` | #90C5F1 | rgb(144,197,241) | Additional text |
| `border-default` | #B5C7D8 | rgb(181,199,216) | Subtle borders, dividers |
| `accent` | #155BD0 | rgb(21,91,208) | Primary actions, links, focus |

## Typography

- MUST use `Inter` as primary font family
- SHOULD use single font family for consistency
- MUST use `51px` / `700` for primary headings
- MUST use `27px` / `500` for body text
- SHOULD reduce font weights (currently 4 detected)
- MUST use `text-balance` for headings and `text-pretty` for body text
- SHOULD use `tabular-nums` for numeric data
- NEVER modify letter-spacing unless explicitly requested

### Text Styles

| Style | Font | Size | Weight | Color | Count |
|-------|------|------|--------|-------|-------|
| `heading-1` | Inter | 51px | 700 | #2D2B30 | 1 |
| `text-43px` | Inter | 43px | 700 | #272729 | 1 |
| `body` | Inter | 27px | 500 | #454547 | 1 |
| `body-secondary` | Inter | 26px | 500 | #3D3C41 | 1 |
| `text-16px` | Inter | 16px | 400 | #6D89B5 | 1 |
| `text-15px` | Inter | 15px | 400 | #8EC7F2 | 1 |
| `text-14px` | Inter | 14px | 400 | #90C5F1 | 1 |
| `text-12px` | Inter | 12px | 300 | #808080 | 1 |
| `caption` | Inter | 11px | 300 | #707070 | 1 |
| `label` | Inter | 10px | 400 | #7E7E7E | 1 |

### Typography Reference

**Font Families:**
- `Inter` (used 18x)

**Font Sizes:** 9px, 10px, 11px, 12px, 14px, 15px, 16px, 26px, 27px, 43px, 51px

## Spacing

- SHOULD use spacing from scale: 2px, 4px, 13px, 34px
- SHOULD use 4px as default gap between elements
