Structure a Kotlin Multiplatform library by defining shared domain models in common code and using expect/actual declarations for platform-specific implementations. This approach enables cross-platform code reuse while maintaining native functionality and supporting coroutine-aware testing patterns.

Build reactive pipelines with Flow and StateFlow in Kotlin coroutines by leveraging structured concurrency and suspend functions. This pattern ensures safe state management and async data streams, applying Kotlin 1.9+ idioms and coroutine-aware testing scaffolding for robust pipeline execution.

Integrate Android Jetpack Compose with ViewModel by driving UI state through StateFlow. This approach applies Material3 theming and navigation best practices, ensuring coroutine-friendly, reactive UI updates that adhere to modern Kotlin idioms and structured concurrency principles.

Yes, this guidance covers Ktor server patterns including routing, serialization, and authentication. It provides senior-level architecture recommendations for coroutine-friendly database access and server-side implementation, ensuring idiomatic Kotlin code for production-grade Ktor applications.

Yes, you can use explicit API mode and sealed classes for Kotlin library design. This Skill provides expert recommendations for DSL construction, extension functions, and sealed-class design idioms, ensuring robust library structuring with Kotlin 1.9+ conventions.

Set up coroutine-aware testing for suspend functions using runTest and coroutine test support. This approach provides proper test scaffolding for multiplatform projects, validating structured concurrency and Flow pipelines without blocking the test thread.
