Compose expert skill for UI development. Guides state management decisions (@Composable, remember, mutableStateOf, derivedStateOf, State hoisting), view composition and structure, Modifier chains, lazy lists, navigation, animation, side effects, theming, accessibility, and performance optimization. Backed by actual androidx source code analysis. Use this skill whenever the user mentions Compose, @Composable, remember, LaunchedEffect, Scaffold, NavHost, MaterialTheme, LazyColumn, Modifier, recomposition, Style, styleable, MutableStyleState, or any Jetpack Compose API. Also trigger when the user says "Android UI", "Kotlin UI", "compose layout", "compose navigation", "compose animation", "material3", "compose styles", "styles api", or asks about modern Android development patterns. Even casual mentions like "my compose screen is slow" or "how do I pass data between screens" should trigger this skill.

Launch and use a Kotlin/JVM REPL against a real project classpath to prototype snippets, inspect runtime behavior, validate imports and overloads, and debug small pieces of Kotlin code before editing source files or writing tests. Use when Codex needs to check a Kotlin hypothesis against compiled project outputs in a Gradle JVM or Kotlin Multiplatform JVM target, or must resolve the full REPL classpath and dependency jars automatically.

Use when Codex needs to check a Kotlin hypothesis against compiled project outputs, framework APIs, or dependency resolution in a live REPL.
