What it does

Kmp Starter Mvi is an agent skill from DevAtrii/Kmp-Starter-Template. How to implement MVI on the KMP Starter Template — State, Actions, Events, and the MviViewModel base class (initialState, onAction, onStateStart, emitEvent/emitEventAsync).

Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Project scaffolding. The repository describes itself as: Starter template is a multi-module KMP boilerplate for Android & iOS with clean architecture and high-quality code. It handles basics like remote config, in-app purchases, and… The licence is MIT.

Example prompts

“/kmp-starter-mvi”

What it can do on your machine

Read from SKILL.md and the folder at commit a8f7b27. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are kotlin).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kmp Starter Mvi loads about 879 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 184 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~47
When it runs · the whole SKILL.md, loaded when a task matches: ~879

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: How to implement MVI on the KMP Starter Template — State, Actions, Events, and the MviViewModel base class (initialState, onAction, onStateStart, emitEvent/emitEventAsync).
author: DevAtrii
license: MIT

MVI

Every ViewModel extends Starter's MviViewModel<State, Action, Event> from:

com.kmpstarter.ui_utils.viewmodels.MviViewModel

Do not write plain ViewModel classes. Always subclass MviViewModel. Each ViewModel consists of State, Actions, Events. Keep terminology exact — no Intent/Effect/Mutation.

Shape

kotlin

data class HomeState(
    val name: String = "",
    val isLoading: Boolean = false,
)

sealed class HomeAction {
    data class EnteringName(val name: String) : HomeAction()
    data object SaveButtonClicked : HomeAction()
}

sealed class HomeEvent {
    data class ShowSnackbar(val message: String) : HomeEvent()
}

class HomeViewModel : MviViewModel<HomeState, HomeAction, HomeEvent>() {
    override val initialState get() = HomeState()

    override fun onStateStart() {
        loadData()
    }

    override fun onAction(action: HomeAction) {
        when (action) {
            is HomeAction.EnteringName -> _state.update { it.copy(name = action.name) }
            HomeAction.SaveButtonClicked -> emitEventAsync(HomeEvent.ShowSnackbar("Saved!"))
        }
    }
}

Key rules

initialState must use get(): override val initialState get() = State(). A non-get() initializer crashes.
Never read SavedStateHandle inside initialState. Read it in init {}, then _state.update { ... }.
onAction(action) — single entry point for all user interactions; when dispatch here.
onStateStart() — lifecycle hook, runs when UI starts collecting state; load initial data here.
Update state with _state.update { it.copy(...) }.

Constructor params into state

MviViewModel supports constructor args too — do not switch to a plain ViewModel for parameterized screens.

kotlin

class NotesViewModel(private val noteId: String) : MviViewModel<NotesState, NotesAction, NotesEvent>() {
    override val initialState get() = NotesState()

    init {
        _state.update { it.copy(noteId = noteId) }
    }
}

Pass nav params via parameterOf(...) + koinViewModel { parametersOf(...) } (see koin skill).

Emitting events

Always use the functions provided by MviViewModel:

emitEvent(event) — suspend; use inside an existing coroutine.
emitEventAsync(event) — non-suspend; launches in viewModelScope. Prefer for one-offs.
emitEventInViewModel is deprecated (renamed to emitEventAsync).

Never hand-roll your own Channel/SharedFlow event stream — MviViewModel.uiEvents already exposes one (SharedFlow, replay = 0).

Observing events in UI

kotlin

import com.kmpstarter.ui_utils.side_effects.ObserveAsEvents

@Composable
fun HomeScreen(viewModel: HomeViewModel = koinViewModel()) {
    val state by viewModel.state.collectAsStateWithLifecycle()

    ObserveAsEvents(flow = viewModel.uiEvents) { event ->
        when (event) {
            is HomeEvent.ShowSnackbar -> SnackbarController.sendMessage(event.message)
        }
    }

    // render state, send actions
}

ObserveAsEvents is lifecycle-aware (won't fire in background); prefer it over LaunchedEffect.

Reference

features/core/presentation/.../viewmodels/OnboardingViewModel.kt is the canonical example (State/Actions/Events, Logics, EventsTracker, emitEvent).
