The prototype skill helps you build throwaway code that answers one concrete question before you commit to a real implementation. Use it to test logic, state transitions, data shape, or UI direction with a runnable prototype that matches the host repo’s conventions. It’s ideal when you need a quick prototype guide, not a final feature.

The design-an-interface skill helps you explore radically different API and module interface shapes before you commit. It is built for frontend development and other module-design work where you want requirements first, then multiple options, trade-off comparison, and a cleaner caller-facing contract.

ckm:design-system helps you build three-layer tokens, component specs, CSS variables, Tailwind mappings, and brand-consistent slide assets from a clear token architecture.

The accessibility-compliance skill helps teams audit and improve web or mobile UI with practical WCAG 2.2, ARIA, keyboard access, screen reader, and mobile accessibility guidance. Best for UX audits, component fixes, and implementation-ready recommendations.
