using-chrisbanes-skills

name	using-chrisbanes-skills
description	Use when a Kotlin, Android, or Jetpack Compose task is too broad for any single focused skill to obviously apply, especially for general review, refactor, architecture, state, performance, testing, or UI API design work.

Using chrisbanes skills

Router only. Use this skill to choose the focused skill or skills for the task, then load those focused skills before giving detailed advice or editing code.

If a request already clearly matches a focused skill, use that skill directly. If several areas affect the work, load each relevant focused skill before acting on that area.

Common routes

Task signal	Start with
Broad Compose screen review or refactor	compose-state-holder-ui-split, then add state, effects, layout, testing, or performance skills as needed
Local Compose state, bare local var, remember { mutableStateOf(...) }, mutableStateListOf, or @ReadOnlyComposable	compose-state-authoring
Deciding whether state belongs locally, hoisted, in a plain state holder, or in a screen state holder	compose-state-hoisting
ViewModel, component, controller, navigation, Flow collection, or dependency wiring mixed with UI layout	compose-state-holder-ui-split
LaunchedEffect, DisposableEffect, SideEffect, rememberCoroutineScope, rememberUpdatedState, navigation, snackbar, analytics, focus requests, or event Flow collection	compose-side-effects
Recomposition, jank, compiler reports, Layout Inspector counts, unstable params, scroll reads, animation reads, or back-writing state across phases	compose-recomposition-performance
Known Compose stability or skippability question, compiler classes.txt / composables.txt, collection parameters, or strong skipping	compose-stability-diagnostics
Frame-rate state reads from scroll, animation, gestures, layout, or draw; value-form layout/draw modifiers; measurement state back-writing	compose-state-deferred-reads
Modifier parameters, root layout placement, hardcoded layout decisions, or modifier chain style	compose-modifier-and-layout-style
Reusable Compose component API with variable visual content, primitive content params, optional content params, or boolean shape flags	compose-slot-api-pattern
Compose visibility, value, color, size, transition, content swap, or choosing an animation API	compose-animations
Keyboard, TV, desktop, D-pad, FocusRequester, focusProperties, key events, or initial focus behavior	compose-focus-navigation
Compose UI tests, screenshot tests, previews, semantics, fake image loading, keyboard input, focus assertions, or interaction state tests	compose-ui-testing-patterns
Coroutine scope ownership, init { launch }, non-suspending APIs that launch work, runBlocking, or cancellation handling	kotlin-coroutines-structured-concurrency
Kotlin branching, when expressions, guard conditions, sealed type exhaustiveness, smart casts, nullable branching, or complex if/else chains	kotlin-control-flow
StateFlow, SharedFlow, Channel, stateIn, SharingStarted, .value, one-shot events, sentinel initial values, or expensive update blocks	kotlin-flow-state-event-modeling
Kotlin Multiplatform platform APIs, source set boundaries, expect/actual, interfaces for platform services, permissions, files, sensors, native SDKs, or Compose Multiplatform interop	kotlin-multiplatform-expect-actual
Kotlin function placement, member vs top-level function, extension functions, factories, primitive receivers, or extensions on String, collections, Flow, framework, or third-party types	kotlin-functions
Single-field domain types, primitive obsession, or choosing @JvmInline value class vs data class	kotlin-types-value-class
Polling or shepherding PRs/MRs, triaging review comments, fixing CI failures, or keeping reviews moving	shepherd

Combining skills

• For Compose event handling from a ViewModel or component, use compose-state-holder-ui-split, compose-side-effects, and, if the event primitive matters, kotlin-flow-state-event-modeling.
• For performance work, start with compose-recomposition-performance. It routes deeper to stability or deferred-read fixes.
• For animations triggered by state, use compose-animations together with compose-state-holder-ui-split; for frame-rate-driven animation values, also load compose-state-deferred-reads.
• For reusable UI components, pair compose-modifier-and-layout-style with compose-slot-api-pattern when both placement and content flexibility are in play.
• For tests around focus behavior, use compose-focus-navigation first, then compose-ui-testing-patterns for test shape.
• For Kotlin state or platform-boundary work that also changes branching shape, combine the domain skill with kotlin-control-flow.
