kotlin-coroutines-structured-concurrency

What problem does it solve?

This skill helps you prevent subtle Kotlin coroutine issues caused by unowned CoroutineScopes, hidden launch sites, incorrect cancellation handling, and unsafe blocking primitives that lead to silent failures or broken cancellation propagation.

Core Features & Use Cases

• Structured concurrency review guidance: Identify patterns like stored CoroutineScope, construction-time launches, and fire-and-forget launches from non-UI layers.
• Cancellation-safe error handling: Detect and correct broad catches (e.g., Exception/Throwable) that swallow CancellationException, and ensure cancellation rethrows correctly.
• Boundary-correct coroutine design: Use suspend APIs so callers own scopes, and apply the UI boundary carve-out only at state-holder layers like ViewModels.

Quick Start

Use this skill when reviewing Kotlin coroutine code and you notice a stored CoroutineScope, an init/initializer launch, a non-suspending function that calls scope.launch, a runBlocking in app code, or a catch that might swallow cancellation.
