What it does

Kmp Starter UI is an agent skill from DevAtrii/Kmp-Starter-Template. Reusable Compose UI kit on the KMP Starter Template — starter/ui/components, starter/ui/utils, and starter/ui/layouts. Know what's already built before writing new UI.

Its SKILL.md is about 1.1k 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 Frontend & Design, covering Design systems and 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.

When your agent uses it

  • Tasks that involve Design systems
  • Tasks that involve Project scaffolding

Example prompts

  • “/kmp-starter-ui”

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.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • starter.atherio.dev

    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 UI loads about 1.1k tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 292 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

UI

Reuse Starter's Compose UI kit. Do not write a component, layout, or Compose helper if Starter already ships one.

Modules (all in starter/):

ModuleAccessorContents
starter/ui/componentsprojects.starter.ui.componentsReusable composables
starter/ui/utilsprojects.starter.ui.utilsCompose utilities, ViewModels, popups, theme, modifiers
starter/ui/layoutsprojects.starter.ui.layoutsFull-screen layout composables

Dep chain: layouts → components → ui/utils → starter/utils. Adding a higher module pulls the lower ones in automatically. Non-UI helpers live in starter/utils (see the utils skill).

components — reusable composables

  • Buttons: KmpButton, LoadingButton, GenerateAiButton, GoogleSignInButtonUI, TimerCloseButton, PillActionButton, PillActionsContainer.
  • Cupertino (iOS style): CupertinoSwitch, CupertinoSection, CupertinoSectionRow (value / switch / stepper / dropdown overloads), CupertinoDropdownMenu, CupertinoDropdownItem, CupertinoLazyColumn.
  • Text: HeaderText, SheetDialogHeader, ErrorText, FiltrationLabel, DividerWithText, TextWithButton.
  • Text fields: FormTextField, FormPasswordTextField, SearchTextField (use FieldState from starter/utils).
  • Other: StepsProgress, SelectableListCard, CleanForm, CoilImage, Base64Image, FiltrationChip, FadeIn, Floating, SimpleNavigationTopBar, SimpleMediumNavigationTopBar, LockOverlay, ScrollableColumn.

ui/utils — Compose utilities

  • MVI: MviViewModel<State, Action, Event> (always use, never plain ViewModel), Flow.collectInViewModel, Channel.sendInViewModel, MutableSharedFlow.emitInViewModel.
  • Side effects: ObserveAsEvents, LaunchOnce, LaunchOnStart.
  • StateFlow: MutableStateFlow.reset, SavedStateHandle.getMutableStateFlow / getMutableStateFlow2.
  • Popups: BaseDialog, DeleteDialog, DatePickerDialog, BaseBottomSheet, SheetState.hideProperly.
  • Theme: Dimens, LocalThemeMode, ThemeMode.getIcon, isAppInDarkTheme, getDynamicColorScheme.
  • Color: Color.fromHex, Color.toHexString, complimentaryColor, brightness, ColorFilter.lightDarkTint.
  • Modifiers: Modifier.grayScale(), Modifier.customOverscroll(...).
  • Image: ImageBitmap.toByteArray/toBase64String/resize/compress/fromByteArray/fromBase64String, ImageVector.asVectorPainter/toImageBitmap/toByteArray/toBase64String, decodeBase64ToImageBitmap.
  • Cross-platform services: rememberKeyboardInfo, isKeyboardVisible, getScreenSize/ScreenSizeValue, rememberScreenController, rememberChromeTabs, rememberStarterStoreManager, rememberUpdateLauncher/AppUpdateProvider, rememberStarterFileManager.
  • DataStore (Compose): remember*DataStore / rememberMutable*DataStore.
  • Preview: @AllDevicePreviews.
  • Focus: FocusManager.moveDown/Up/Next/Previous/....

layouts — full-screen states

  • LoadingLayout — centered spinner, theme-aware dimmed background.
  • EmptyStateWithAction — hero icon + title + description + CTA button.
  • MeasurableLayout — internal; exposes LocalScreenSize (Offset).

Rules

  • Search before building. For every new composable/Compose helper, check the three modules first — reuse or extend, never duplicate.
  • Components belong in starter/ui/components only if reusable; app-specific UI stays in your feature's presentation layer.
  • Use Dimens for spacing/size, never hardcoded dp.
  • Use FieldState + FormTextField for form fields.
  • Use MviViewModel, ObserveAsEvents, and the utils above — don't hand-roll equivalents.
  • Color parsing → Color.fromHex (the parseHexColor* functions are deprecated).
