## Description

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

### Before you start: check the package version
This skill needs Asset Transformer Toolkit 4.0.0 or later (`com.unity.industry.toolkit`). Earlier versions don't have the `ATTAssistantUtilities` API every workflow below relies on.

1. Read the resolved version of `com.unity.industry.toolkit` from `Packages/packages-lock.json` (fall back to `Packages/manifest.json`).
2. **Not installed:** tell the user this workflow needs Asset Transformer Toolkit 4.0 or later, which is an entitled Unity package they may need access to through their Unity plan, and stop. Don't add it to the manifest yourself.
3. **Installed below 4.0.0:** tell the user which version you found and that 4.0 or later is required, and ask before upgrading. Don't fall back to older APIs, raw C# against internal types, or reflection.
4. **4.0.0 or later:** continue.

### API Reference
Tool functions are provided by `Unity.Pixyz.Plugin4Unity.Editor.AI.ATTAssistantUtilities`. They are documented inline in each reference file below alongside the classes they operate on.

### Technical Notes
Pixyz Plugin is the former name of Asset Transformer Toolkit. Prefer using the term 'Asset Transformer Toolkit' when addressing the user, unless the user is using the term 'Pixyz'
Most classes and code are in the Unity.Pixyz.Plugin4Unity.Editor assembly.
Asset Transformer Toolkit is NOT the same thing as Asset Transformer Studio/Pixyz Studio. NEVER rely on information about Asset Transformer Studio.
