What tools are required for this skill to work?

This skill requires the unity-mcp-server plugin, which provides the necessary tools like create_class and edit_structured to modify Unity project files.

Is this skill used for in-game UI?

No, IMGUI is specifically for Unity Editor extensions. For runtime game UI, you should use the UGUI or UI Toolkit design skills instead.

Can I create complex utility windows with this?

Yes, the skill includes patterns for handling scroll views, toolbars, search filters, and persistent serialized state within custom EditorWindows.

Does it support Custom Inspectors for components?

Absolutely. It provides implementation patterns for overriding OnInspectorGUI and using SerializedProperties to build robust and reactive component editors.

What is the difference between GUILayout and EditorGUILayout in this skill?

GUILayout provides basic layout controls that work everywhere, while EditorGUILayout offers rich, editor-specific controls like PropertyFields and HelpBoxes used specifically for Unity tooling.
