What it does
Understands, edits, and generates Unity UI Toolkit UXML and USS with flex layouts. Use for requests involving UI Toolkit, UIElements, UIDocument, PanelSettings, custom elements, or UI runtime binding.
Understand existing Unity UI Toolkit code, make targeted edits, generate new UXML/USS files, Manipulators, and handle UI runtime binding.

When explaining UI structure, use this format:
[ElementType] name="elementName" class="class1 class2"
├── [ChildType] name="childName"
│ └── [GrandchildType]
└── [ChildType] class="another-class"
