Provides a workflow for building and reviewing high-quality React and React Native UI with the Coinbase Design System (CDS). Use this skill to create UI or make visual changes to existing UI with CDS components, tokens, style props, icons, and illustrations. Use it for explicit CDS-adherence audits and reviews, not non-visual logic, data, analytics, navigation, tests, generated code, or refactoring. Examples: "build this screen", "fix spacing on this component", "replace this UI with CDS components", "perform a CDS audit on our changes", "check our codebase for CDS adherence", "does this feature use CDS well?"
