## What it does

The skill directs AI agents to follow Notion visual conventions. It defines `#F6F6F6` as the base page background, `#97CAEE` for accents, and mandates an accessible text contrast ratio of at least 4.5:1. Typography relies on Inter, setting primary headings to 66px bold and body copy to 16px.

Layouts target a 1920px base viewport, using `h-dvh` instead of `h-screen`. Spacing strictly follows a 4px grid scale. Border radiuses are locked to 3px, 4px, 6px, and 15px.

Component guidelines prohibit blocking paste events in text fields and mandate `AlertDialog` for destructive actions. Transitions cannot touch layout metrics like margins or dimensions; only `transform` and `opacity` are allowed under a 200ms limit.

## Requirements
- Works with: Notion

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- build Notion-style light mode user interfaces
- enforce Inter typography and semantic color tokens
- constrain UI spacing to a 4px grid scale
- restrict CSS transitions to transform and opacity

## Example prompts
- Build a settings card using the Notion design system tokens
- Create a confirmation dialog with an AlertDialog component and 4px border radius
- Generate a document outline list with Inter font and #F6F6F6 background

# Notion UI Skills

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

## When to Apply

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

## Colors

- SHOULD use light backgrounds for primary surfaces
- MUST use `#F6F6F6` as page background (`surface-base`)
- MUST use `#97CAEE` for primary actions and focus states (`accent`)
- SHOULD reduce color palette (currently 15 colors detected)
- MUST maintain text contrast ratio of at least 4.5:1 for accessibility

### Semantic Tokens

| Token | HEX | RGB | Usage |
|-------|-----|-----|-------|
| `surface-base` | #F6F6F6 | rgb(246,246,246) | Page background |
| `surface-raised` | #E5E5E4 | rgb(229,229,228) | Cards, modals, raised surfaces |
| `surface-overlay` | #DFEFFE | rgb(223,239,254) | Overlays, tooltips, dropdowns |
| `text-primary` | #5D686A | rgb(93,104,106) | Headings, body text |
| `text-2` | #3E3E3E | rgb(62,62,62) | Additional text |
| `text-tertiary` | #505050 | rgb(80,80,80) | Additional text |
| `border-default` | #EDEEEC | rgb(237,238,236) | Subtle borders, dividers |
| `accent` | #97CAEE | rgb(151,202,238) | Primary actions, links, focus |

## Typography

- MUST use `Inter` as primary font family
- SHOULD use single font family for consistency
- MUST use `66px` / `700` for primary headings
- MUST use `16px` / `500` for body text
- SHOULD reduce font weights (currently 6 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 | 66px | 700 | #212121 | 1 |
| `text-29px` | Inter | 29px | extra_bold | #292929 | 1 |
| `text-27px` | Inter | 27px | 400 | #4D4D4D | 1 |
| `text-21px` | Inter | 21px | 500 | #252525 | 1 |
| `text-19px` | Inter | 19px | semi_bold | #333333 | 1 |
| `text-18px` | Inter | 18px | semi_bold | #383838 | 1 |
| `text-18px` | Inter | 18px | 400 | #4E4E4E | 1 |
| `body` | Inter | 16px | 500 | #545454 | 1 |
| `body-secondary` | Inter | 16px | 400 | #9B9B9B | 1 |
| `body-secondary` | Inter | 15px | 400 | #5F5F5F | 2 |

### Typography Reference

**Font Families:**
- `Inter` (used 33x)

## Spacing

- MUST use 4px grid for spacing
- SHOULD use spacing from scale: 1px, 2px, 4px, 5px, 6px, 11px, 14px, 18px
- SHOULD use 1px as default gap between elements
- NEVER use arbitrary spacing values (use design scale)
- SHOULD maintain consistent padding within containers

## Borders

- MUST use border-radius from scale: 3px, 4px, 6px, 15px
