structuring-a-compose-test
structuring-a-compose-test
Use this skill to structure a Jetpack Compose UI test class the way androidx itself writes them — `@MediumTest` + `@RunWith(AndroidJUnit4::class)`, a single `createComposeRule(StandardTestDispatcher())` rule, hoisted `mutableStateOf` declared above `setContent { }`, and the Test → Find → Assert → Act → Re-assert flow. Covers when to use `createAndroidCompos…
developing-with-compose-previews
developing-with-compose-previews
Use this skill to make `@Preview` functions the primary feedback loop for Jetpack Compose UI work — preview-driven development. Covers hoisting state out of composables so a preview never needs a `ViewModel` or DI graph, `LocalInspectionMode` for conditional preview rendering (e.g. placeholder instead of Coil/Glide), `@PreviewParameter` + `PreviewParameterP…
jetpack-compose-builder
jetpack-compose-builder
Builds Android Jetpack Compose UI with hoisted state, unidirectional data flow, and recomposition-safe patterns backed by measured stability rules. Use when someone asks "build this screen in Compose", "where should this state live", "why does my LazyColumn stutter", or is writing Composable functions, ViewModel and StateFlow wiring, or fixing recomposition…
android-compose
android-compose
Build high-performance declarative UI with Jetpack Compose. Use when writing Composable functions, optimizing recomposition, hoisting state, or working with LazyColumn and side effects; defer deep-link and navigation routing to android-navigation.
collecting-flows-safely
collecting-flows-safely
Use this skill to migrate Compose UI from `collectAsState()` to `collectAsStateWithLifecycle()`, hoist `Flow<T>` parameters out of composables, and apply `.conflate()` / `.distinctUntilChanged()` / `snapshotFlow` so background CPU and battery stop draining and chatty flows stop invalidating the UI per emission. Covers ViewModel `StateFlow`/`SharedFlow` cons…
compose-multiplatform
compose-multiplatform
Compose Multiplatform (CMP) by JetBrains — declarative UI framework that runs on Android, iOS, JVM Desktop, and Web (Wasm). Built on top of Jetpack Compose. Covers @Composable functions, state hoisting, side effects, navigation (Voyager, Decompose), Material 3, theming, and platform-specific UI bridging on iOS. USE WHEN: user mentions "Compose Multiplatfor…
compose-state-and-effects
compose-state-and-effects
Use when writing or reviewing Jetpack Compose state ownership, remember state, state hoisting, screen state holders, LaunchedEffect, DisposableEffect, SideEffect, Flow collection, navigation, snackbar, analytics, or focus requests.
kotlin-coroutines
kotlin-coroutines
Write safe, structured concurrent code with Kotlin Coroutines. Use for suspend functions, coroutine scopes, cancellation, and coroutine leaks; defer Java Virtual Threads, Android WorkManager/Fragment lifecycle, Compose state hoisting, and Detekt/tooling configuration.
optimizing-lazy-layouts
optimizing-lazy-layouts
Use this skill to fix scroll jank, lost item state, and broken animateItem() animations in LazyColumn, LazyRow, LazyVerticalGrid, and LazyHorizontalGrid. Covers stable item keys, contentType for mixed-type feeds, Modifier.animateItem() requirements, hoisting modifier chains and painters out of the items lambda, and validating item composable stability. Use …
putio
putio
Manage a put.io account via the kaput CLI (transfers, files, search) — hoist the mainsail, add magnets/URLs, and check transfer status; best paired with the chill-institute skill.
react-async-waterfalls
react-async-waterfalls
Eliminates async request waterfalls in React applications by parallelizing data fetching, hoisting fetches to route and page level, and using streaming SSR with Suspense boundaries.
