kotlin-coroutines-flows
Kotlin Coroutines and Flow patterns for Android and KMP — structured concurrency, Flow operators, StateFlow, error handling, and testing.
npx skills add mturac/everything-openai-codex --skill kotlin-coroutines-flows --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Kotlin Coroutines & Flows Patterns for structured concurrency, Flow-based reactive streams, and coroutine testing in Android and Kotlin Multiplatform projects. ## When to Activate - Writing async code with Kotlin coroutines - Using Flow, StateFlow, or SharedFlow for reactive data - Handling concurrent operations (parallel loading, debounce, retry) - Testing coroutines and Flows - Managing coroutine scopes and cancellation ## Structured Concurrency ### Scope Hierarchy ``` Application └── viewModelScope (ViewModel) └── coroutineScope { } (structured child) ├── async { } (concurrent task) └── async { } (concurrent task) ``` Always use structured concurrency — never `GlobalScope`: ```kotlin // BAD GlobalScope.launch { fetchData() } // GOOD — scoped to ViewModel lifecycle viewModelScope.launch { fetchData() } // GOOD — scoped to composable lifecycle LaunchedEffect(key) { fetchData() } ``` ### Parallel Decomposition Use `coroutineScope` + `async` for parallel work: ```kotlin suspend fun loadDashboard(): Dashboard = coroutineScope { val items = async { itemRepository.getRecent() } val stats = async { statsRepository.getToday() } val profile = async { userRepository.getCurrent() } Dashbo

What does the kotlin-coroutines-flows skill do?
Kotlin Coroutines and Flow patterns for Android and KMP — structured concurrency, Flow operators, StateFlow, error handling, and testing.
How do I install it?
Run `npx skills add mturac/everything-openai-codex --skill kotlin-coroutines-flows --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mturac/everything-openai-codex, a repository with 84 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
