What problem does it solve? Generated UI asset packs contain widget slices with 9-slice margins and fill-rect metadata, but turning those flat PNGs into functional, stretchable game UI controls requires manual interpretation of sliceMeta and correct node configuration in Summer Engine. ## Core Features & Use Cases - 9-Slice Panel Wiring: Convert frameMargins percentages into pixel patch margins on NinePatchRect nodes for panels and buttons. - Value-Driven Widgets: Configure TextureProgressBar with fill rects for progress bars, and HSlider with TextureRect overlays for sliders. - Toggle Pairs and Composites: Swap on/off textures via pairWith metadata, and reconstruct composite panels by grouping children with parentSliceIndex and zOrder. - Use Case: After generating a UI kit with create-asset-sheet, wire the detected slider, progress bar, and toggle slices into working Summer Engine controls that stretch and respond to game state. ## Quick Start Use the use-widget-asset skill to wire the panel and progress bar slices from my generated asset pack into Summer Engine controls.
