• android-source-search

  Use when needing to fetch Android source code — AOSP platform internals (@hide APIs, framework classes, system services) or AndroidX/Jetpack library source and samples. Also use when public docs are insufficient to complete a task and implementation details must be read directly from source.

• android-testing

  Use when writing, fixing, or refactoring Android/KMP code in Kotlin — a test-first (RED-GREEN-REFACTOR) foundation plus the Android/KMP test traps: Compose-test dispatching (StandardTestDispatcher default, the two-schedulers trap), semantics-first selectors, choosing the smallest test shape, test-clock vs wall-clock, animation/screenshot determinism, and a `commonTest` name that fails the iOS com…

• android-ux

  Use when designing or reviewing Android UI — applies Material Design 3 UX principles covering touch targets, spacing, navigation patterns, accessibility, animation timing, and platform conventions. Includes an M3 compliance audit that scores screens across 10 categories. Complements the compose skill with design-level decisions.

• datastore

  Use when persisting key-value preferences or small typed settings on Android or KMP with Jetpack DataStore — Preferences vs Typed (Proto/JSON) vs Room selection, the IOException and corruption-recovery error traps, serializers with corruption handlers, and the KMP factory with per-platform file paths. Triggers on DataStore, Preferences, PreferenceDataStoreFactory, DataStoreFactory, preferencesDat…

• gradle-build-performance

  Use when Android/Gradle builds are slow — diagnosing bottlenecks with build scans, enabling configuration cache, migrating kapt to KSP, fixing cache misses, and optimizing CI/CD build times.

• kmp-boundaries

  Use when designing Kotlin Multiplatform boundaries — choosing between expect/actual, common interfaces with platform bindings, or separate platform screens. Covers platform services (clipboard, share, haptics, permissions, files, settings, sensors, biometrics), native SDKs, source-set hierarchies (commonMain, skikoMain, appleMain, androidMain), Compose Multiplatform interop, and capability granul…

• koin

  Use when setting up or working with Koin in Android or KMP projects — module declarations with Classic DSL or KSP annotations, ViewModel injection in Compose, scopes, Nav 3 entry providers, application startup, and compile-time verification via `verify()`. Triggers on Koin, `single`, `factory`, `koinViewModel`, `koinInject`, `parametersOf`, `startKoin`, "KMP DI", "shared DI".

• modularization

  Use when writing or changing any class, object, function, property, or constant in a multi-module Android/Kotlin project (settings.gradle(.kts) includes more than one module — :app, :core:*, :feature:*, :data, etc.). Symptoms — a top-level declaration left at Kotlin's default public visibility; an implementation class, mapper, helper, constant, or UI-state holder reachable from another module tho…
