Does this skill support Kotlin Multiplatform (KMP)?

Yes, it provides specific guidance for KMP, including shared networking patterns, expect/actual implementations, and cross-platform concurrency best practices.

How does it handle coroutine testing?

The skill emphasizes using runTest with TestDispatcher rather than real-time delays, ensuring your asynchronous code is tested deterministically and reliably.

Which backend framework does it prefer?

It provides a neutral decision framework to help you choose between Ktor (for explicit, lightweight, KMP-compatible needs) and Spring Boot (for enterprise, convention-over-configuration projects).

Can it help with Java to Kotlin migration?

Absolutely. It includes specific logic for identifying platform types and adding explicit nullability boundaries to prevent runtime exceptions in migrated code.

Mobile Development

Implements idiomatic, production-grade Kotlin patterns for backend, Android, and Multiplatform development.

Acerca de

Build Kotlin is a specialized Claude Code skill designed to guide developers through the complexities of modern Kotlin development. It provides elite, structured frameworks for decision-making regarding coroutine scopes, Flow selection, and scope functions while enforcing best practices for null safety and structured concurrency. Whether building robust backend services with Ktor or Spring Boot, or developing cross-platform applications via Kotlin Multiplatform (KMP), this skill ensures your code adheres to production-grade standards, avoids common platform-type pitfalls, and utilizes deterministic testing patterns with Kotest and MockK.

Características Principales

Standardized patterns for structured concurrency and lifecycle-aware coroutines.
Automatic enforcement of Kotlin null-safety best practices for Java interop.
Advanced Flow selection logic for StateFlow, SharedFlow, and Channels.
Deterministic testing patterns using runTest, Kotest, and MockK.
3 GitHub stars
Framework-specific architectural guidance for Ktor and Spring Boot.

Casos de Uso

Migrating Java codebases to idiomatic, null-safe Kotlin with correct platform type handling.
Implementing reactive UI states and events in Android or Kotlin Multiplatform projects.
Designing highly concurrent backend services using Ktor or Spring Boot.
