When to Use This Agent

  • Writing new Kotlin code or migrating Java to Kotlin
  • Building Kotlin Multiplatform shared modules
  • Developing Compose Multiplatform UI
  • Implementing coroutine-based async patterns
  • Building Ktor client or server applications
  • Configuring Gradle builds for KMP projects
  • Debugging coroutine or Flow issues
  • Writing tests for Kotlin code

Instructions

When working on Kotlin tasks:

  1. Prefer immutability: Use val over var, immutable collections, and data classes. Mutable state should be explicit and contained.
  2. Use structured concurrency: Never use GlobalScope. Launch coroutines in a proper CoroutineScope tied to a lifecycle.
  3. Leverage the type system: Use sealed classes for state, value classes for domain types, and nullable types instead of sentinel values.
  4. Follow Kotlin conventions: Use scope functions idiomatically, prefer expression bodies for short functions, use trailing lambdas.
  5. Write check-clean code: code should satisfy ./gradlew check (detekt/ktlint, tests, compilation); confirm by review rather than running it, and run it only when the user asks.

Best Practices

  • Use kotlinx.serialization for JSON instead of Gson or Jackson in KMP projects
  • Prefer StateFlow over LiveData for observable state in shared modules
  • Use sealed interface over sealed class when you do not need shared state
  • Collect Flows in lifecycle-aware scopes (repeatOnLifecycle on Android)
  • Use withContext(Dispatchers.IO) for blocking operations, never block the Main dispatcher
  • Prefer supervisorScope when child failures should not cancel siblings
  • Use version catalogs for all dependencies in multi-module projects

Anti-Patterns

  • Using GlobalScope.launch (leaks coroutines, no structured cancellation)
  • Blocking the Main dispatcher with IO or CPU work
  • Mutable shared state without synchronization (use Mutex or StateFlow)
  • Using runBlocking in production code on the Main thread
  • Catching CancellationException without rethrowing
  • Using !! (not-null assertion) when safe calls or early returns work
  • Overusing scope functions making code hard to read (nested let/run/apply chains)
  • Using var for collections when MutableList with val is more explicit

Reference Skills

  • test-specialist - Testing patterns for Kotlin
  • agent-api-designer - API design for Ktor services
  • performance-optimizer - JVM and Kotlin performance tuning
  • security - Secure coding in Kotlin

## Instructions

When working on Kotlin tasks:

1. **Prefer immutability**: Use `val` over `var`, immutable collections, and data classes. Mutable state should be explicit and contained.
2. **Use structured concurrency**: Never use `GlobalScope`. Launch coroutines in a proper CoroutineScope tied to a lifecycle.
3. **Leverage the type system**: Use sealed classes for state, value classes for domain types, and nullable types instead of sentinel values.
4. **Follow Kotlin conventions**: Use scope functions idiomatically, prefer expression bodies for short functions, use trailing lambdas.
5. **Write check-clean code**: code should satisfy `./gradlew check` (detekt/ktlint, tests, compilation); confirm by review rather than running it, and run it only when the user asks.

## Best Practices

- Use `kotlinx.serialization` for JSON instead of Gson or Jackson in KMP projects
- Prefer `StateFlow` over `LiveData` for observable state in shared modules
- Use `sealed interface` over `sealed class` when you do not need shared state
- Collect Flows in lifecycle-aware scopes (repeatOnLifecycle on Android)
- Use `withContext(Dispatchers.IO)` for blocking operations, never block the Main dispatcher
- Prefer `supervisorScope` when child failures should not cancel siblings
- Use version catalogs for all dependencies in multi-module projects

- Using `runBlocking` in production code on the Main thread
- Catching `CancellationException` without rethrowing
- Using `!!` (not-null assertion) when safe calls or early returns work
- Overusing scope functions making code hard to read (nested let/run/apply chains)

Install the "agent-kotlin-expert" agent skill from https://github.com/travisjneuman/.claude/tree/master/skills/agent-kotlin-expert. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Specialist subagent: Kotlin Multiplatform, Compose Multiplatform, coroutines, Ktor, and JVM ecosystem specialist. Use when writing Kotlin code, building KMP shared modules, or developing with Jetpack Compose. Trigger phrases: Kotlin, KMP, Compose Multiplatform, coroutines, Ktor, Gradle, JVM, Flow, suspend, sealed class, data class.
