## What it does

This skill reviews user interface files against the Web Interface Guidelines created by the Vercel engineering team. It inspects layout structure, color schemes, typography, motion, and accessibility attributes. Each issue prints in a compact `file:line` format to speed up corrections.

Execution relies on a pinned copy stored in `references/guidelines.md` as the default source. This keeps checks predictable across environments. You can also fetch the upstream rule set directly from the Vercel repository to inspect recent rule updates.

When run without file arguments, the assistant asks for target files or a glob pattern. The pinned snapshot prevents rule drift between builds.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add nexu-io/open-design --skill web-design-guidelines -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add nexu-io/open-design --skill web-design-guidelines -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add nexu-io/open-design --skill web-design-guidelines -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install nexu-io/open-design web-design-guidelines
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add nexu-io/open-design --skill web-design-guidelines -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/nexu-io/open-design --path skills/web-design-guidelines
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add nexu-io/open-design --skill web-design-guidelines -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/nexu-io/open-design/tree/HEAD/skills/web-design-guidelines/SKILL.md

## When to use it
- Audit frontend code against Vercel interface rules
- Catch accessibility defects in web components
- Inspect typography and spacing inconsistencies
- Locate UI design issues in terse `file:line` format

## Example prompts
- Review my UI code in src/components against web design guidelines
- Check accessibility and typography for Button.tsx
- Audit design and motion in modal.tsx

# Web Interface Guidelines

Review files for compliance with Web Interface Guidelines.

## How It Works

1. Load the pinned guidelines from [`references/guidelines.md`](references/guidelines.md) — this is the default, reproducible execution path
2. Optionally, fetch the latest guidelines from the upstream URL below and diff against the pinned snapshot to see if anything has changed
3. Read the specified files (or prompt user for files/pattern)
4. Check against all rules in the guidelines
5. Output findings in the terse `file:line` format

## Guidelines Source

**Default (pinned):** The vendored copy at [`references/guidelines.md`](references/guidelines.md) is the default execution path. It is a pinned snapshot of the upstream guidelines and guarantees the skill produces reproducible results in any runtime environment.

**Upstream (live):** For users who want the very latest rules, the live source is available at:

```
https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md
```

Fetching the live version is optional — the pinned snapshot is always the baseline.

## Usage

When a user provides a file or pattern argument:
1. Load [`references/guidelines.md`](references/guidelines.md) as the default source
2. Optionally fetch the upstream URL to check for updates
3. Read the specified files
4. Apply all rules from the guidelines
5. Output findings using the format specified in the guidelines

If no files specified, ask the user which files to review.
