## What it does

The skill defines one set of tokens for every interactive element in a product: buttons, inputs, selects, checkboxes, radios, pills, badges, tags, calendars, sliders and toggles. Radius, colour logic, shadow, border and spacing come from that shared place instead of being reinvented per component.

It also sets the order of work. Check whether a component already exists, look for something close in the codebase and generalise it, and only build new when neither fits. Borders follow a two-step rule: at most two width values rather than a `1px, 2px, 3px` scale. Nested corners are concentric and derived with `calc()`, so the outer radius stays right when a token moves.

The skill activates on paths like `components/**`, `**/*.tsx`, `**/tokens/**`, `design-system/**` and `tailwind.config.*`. The text is cut off in the section on heights and padding, so the rest of the family rules cannot be judged from it. If your codebase already has five near-identical button radii, audit first and consolidate after.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill component-family-consistency -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill component-family-consistency -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dembrandt/dembrandt-skills component-family-consistency
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/dembrandt/dembrandt-skills --path skills/component-family-consistency
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill component-family-consistency -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/component-family-consistency/SKILL.md

## When to use it
- align button and input radius on one form
- make badges stop looking like clickable buttons
- find a near-ready component instead of writing a new one
- replace a four-step border width scale with two values
- compute a concentric card radius around a button

## Example prompts
- Review the components in `src/components` for visual consistency: buttons, inputs, badges and pills should share radius, colour, shadow, border and spacing
- My buttons and inputs look like they came from different products — pull them onto one set of tokens
- Before adding a new component, check whether one already exists or something close can be generalised

# Component Family Consistency

Every interactive component in a product — buttons, inputs, selects, checkboxes, radio buttons, pills, badges, tags, calendars, date pickers, sliders, toggles — belongs to the same visual family. They share a common design DNA. A user should be able to look at any component and feel that it belongs to the same product as every other component.

When components are designed in isolation without shared tokens, the product feels assembled from parts rather than built as a whole.

## Reuse Before You Build a New Component

Before creating any component, **audit what already exists** — a new-from-scratch component is another mouth to feed: another entry in the family that must stay consistent (radius, height, states, motion) and another thing to maintain. Building fresh should be the last resort, not the first move. Work down this order:
```
