Write, review, and refactor MVIKotlin code in this repo. Use when the task mentions MVIKotlin, StoreFactory, Store<Intent, State, Label>, CoroutineExecutor, Reducer, Bootstrapper, Labels, MviView, LoggingStoreFactory, TimeTravelStoreFactory, or when implementing a feature store/component wired through Decompose.

This skill should be used when the user is creating or modifying a Decompose component, mentions "ComponentContext", "retainedInstance", "stateKeeper", "instanceKeeper", "InstanceKeeper", "MutableValue", "Value<", component lifecycle, state preservation, instance retaining, back button handling in a component, or when writing a class that implements or extends a Decompose component interface. Also applies when the user asks how to structure a component, how to keep state across config changes, how to implement a ViewModel equivalent with Decompose, or how to handle the back button in a component.

This skill should be used when the user is integrating Decompose with Jetpack or Multiplatform Compose UI, mentions "subscribeAsState", the "Children" composable from Decompose, "stackAnimation", "predictiveBackAnimation", "ChildPages" composable, "ChildPanels" composable, rendering a ChildSlot in Compose, tab navigation with a bottom bar using Decompose, "LifecycleController" for desktop, Compose previews for Decompose components, or back handling in Compose using Decompose's BackHandler.

This skill should be used when the user is implementing navigation with Decompose, mentions "ChildStack", "ChildSlot", "ChildPages", "ChildPanels", "ChildItems", "StackNavigation", "SlotNavigation", "PagesNavigation", "PanelsNavigation", "childStack", "childSlot", "childPages", "childPanels", asks which navigation model to use, asks about push/pop navigation, dialog navigation, pager navigation, tab navigation, master-detail layout, deep linking with Decompose, navigation configuration classes, or "bringToFront".
