Coss Particles

This is essentially a searchable catalog of 484 ready-made UI components built on the COSS design system. Instead of building a form or dialog from scratch, you describe what you need and it points you to copy-paste examples with JSON manifests at coss.com/ui. It covers everything from basic buttons and inputs to complex patterns like autocompletes with async loading and multi-panel accordions. The skill assumes you already have COSS primitives installed in your project. It's most useful when you know COSS exists but don't want to dig through their docs to find the right starter pattern. The index is generated from their registry, so it stays current with their component library.
