## What it does

The skill helps an agent handle files brought into a Unity project from outside it, configure ImporterScriptableObjects, and work with RuleSets, Actions, and LODs. Its references cover the related workflow steps and APIs. Importer fields are handled through the ScriptableObject API rather than reflection.

The project needs `com.unity.industry.toolkit` version 4.0.0 or later, since earlier releases lack an API used by the skill. If the package is missing, the agent is instructed to stop; an older version calls for user approval before an upgrade. Reimporting can take a long time, so the skill leaves that step for an explicit request.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Unity-Technologies/skills --skill asset-transformer-toolkit -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Unity-Technologies/skills --skill asset-transformer-toolkit -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Unity-Technologies/skills --skill asset-transformer-toolkit -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Unity-Technologies/skills asset-transformer-toolkit
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Unity-Technologies/skills --skill asset-transformer-toolkit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Unity-Technologies/skills --path skills/asset-transformer-toolkit
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Unity-Technologies/skills --skill asset-transformer-toolkit -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/Unity-Technologies/skills/tree/HEAD/skills/asset-transformer-toolkit/SKILL.md

## When to use it
- bring an external 3D model into a Unity project
- create or edit an ImporterScriptableObject
- configure a RuleSet and its rules
- set up LODs for a model
- reimport a model when requested

## Example prompts
- Import this 3D model into my Unity project using Asset Transformer Toolkit.
- Check the `com.unity.industry.toolkit` version and configure an importer for this model.
- Create a RuleSet to process this model and set up its LODs.
