Curated by Skill Harbor: a structured-concurrency guide that makes Muse write Kotlin coroutines and Flows correctly on Android and Kotlin Multiplatform. It starts with the scope hierarchy (viewModelScope, coroutineScope, never GlobalScope) and parallel decomposition with async/await, plus supervisorScope for independent children. Flow patterns cover cold flows, StateFlow for UI state with SharingStarted.WhileSubscribed, combining multiple flows into one UI state, and operators like debounce, distinctUntilChanged, flatMapLatest, catch and retryWith exponential backoff. SharedFlow is presented for one-time events like snackbars and navigation, with a sealed Effect interface collected in a composable. Dispatchers get the CPU versus IO versus Main rules with the KMP caveat that Dispatchers.IO is JVM and Android only. Cancellation covers cooperative ensureActive checks and try/finally cleanup, testing covers Turbine assertions on StateFlow and TestDispatcher with advanceUntilIdle, and the skill closes with the anti-patterns to avoid (GlobalScope, catching CancellationException, mutable collections in StateFlow).

Honest caveats: examples assume Android ViewModel and Compose conventions; KMP projects need dispatcher injection for non-JVM targets; it teaches patterns, it does not debug your race conditions for you. Skill Harbor never reviews the code, review it yourself before use.

Install
Copy the install package below, then paste it into MuseThe install prompt below already includes the vetting steps: your agent follows the community checklist before installing anything with executable code. Want more?
Use "Kotlin Coroutines and Flows" with your Muse. Prerequisites: none to install. Pure guidance; a Kotlin Android or KMP project helps. 1. Open the skill: https://github.com/affaan-m/ECC/blob/main/skills/kotlin-coroutines-flows/SKILL.md and copy the full SKILL.md text. 2. Paste it into a chat with Muse and add: "Review this coroutine code for structured-concurrency mistakes: [paste code]." 3. Ask follow-ups like "convert this callback chain to a Flow with proper cancellation" or "write a Turbine test for this StateFlow." Tip: ask "where can this code leak a coroutine and what is the exact fix?" Safety: a skill is plain-text instructions; it runs nothing by itself. Review generated commands before running them.

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
