## What it does

The skill sets guidelines for interface density across desktop, tablet, and mobile views. Trading desks tolerate high density. Operators spend 8 hours there every day. Consumer products require lower density with clear breathing room. Because mobile screens rely on touch, dense layouts cannot be copied there directly.

It includes CSS tokens for spacing scales. They define row heights: 32px for compact mode, 44px for default, and 56px for spacious layouts. When moving desktop views to phones, the skill removes secondary columns and turns tables into card lists. Porting a dense desktop layout straight to mobile ruins touch targets.

Reading load slows down the interface. The rules prioritize cutting words over shrinking fonts and placing key numbers at the start of labels.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill ui-density -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill ui-density -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dembrandt/dembrandt-skills ui-density
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill ui-density -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dembrandt/dembrandt-skills --path skills/ui-density
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill ui-density -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/dembrandt/dembrandt-skills/tree/HEAD/skills/ui-density/SKILL.md

## When to use it
- adapt desktop dashboards for mobile viewports
- configure compact density modes for data tables
- reduce reading load and word count in complex UIs
- set up CSS tokens for multiple spacing scales

## Example prompts
- Make this enterprise data table more compact using CSS tokens
- Reduce this desktop dashboard layout for mobile screens
- This UI feels too crowded, help me simplify the information density

# UI Density

Density describes how much information and how many interactive elements appear in a given area. The right density is not a universal standard — it depends on platform, user type, and session context.

## Platform Defaults

| Platform | Default density | Reason |
|---|---|---|
| Desktop | Medium to high | Large screen, precise input, often primary work surface |
| Tablet | Medium | Touch input, larger than phone but less than desktop |
| Mobile | Low | Small screen, touch targets need space, interrupted sessions |

Never port a dense desktop layout directly to mobile. Remove, collapse, or deprioritise features rather than shrinking them.

## User Type and Density

| User type | Appropriate density | Examples |
|---|---|---|
| Power user / enterprise | High density acceptable | Trading platforms, ERP, analytics, developer tools |
| Occasional / general user | Medium — clear visual breathing room | SaaS dashboards, project management |
| Consumer / first-time user | Low — guided, uncluttered | Onboarding flows, consumer apps, e-commerce |

A trading platform operator sits in the product for 8 hours a day and has learned every pixel — high density serves them. A user visiting a settings page once a month needs clear space and obvious labels.

**Domain experts tolerate complexity — if it solves the *right* problem quickly.** People who know the domain (especially in internal tools) will happily use dense, complex, feature-rich interfaces, because the complexity maps to a mental model they already hold. Two conditions make this work rather than overwhelm:
