Use this skill when writing or modifying GUI code with the Guigui framework (github.com/guigui-gui/guigui): creating or editing a widget, composing a layout, wiring buttons / text inputs / lists, passing shared state down the widget tree, handling pointer or keyboard input, or figuring out why a change to a field does not show up on screen. Covers the widget lifecycle (Build / Layout / Measure / Draw / input), LinearLayout sizing, Env-based dependency injection, the event-key callback pattern, dynamic child lists, and when state changes trigger a rebuild. Not for general Ebitengine rendering questions that do not involve Guigui widgets.
