App Icon Gen

Create reusable cross-platform icon source assets from a JSON spec. The normal route is semantic layered authoring: a small set of meaningful SVG/base-shape layers or deliberately clean PNG fallback layers, rounded preview assets, unrounded app/source assets, and verification evidence. Apple Icon Composer packaging is an optional adapter, not the default contract.

This skill may export rendered PNGs with Icon Composer's bundled ictool when it is locally available on macOS. It does not prove app integration or final platform rendering beyond those exported PNG files.

Hard Contract

For every new or repaired icon, use one generation root: the user-facing delivery directory.
