Orchestrates macro-level UI architecture, complex Jetpack Compose structures, and screen-to-screen flows. Use this skill to implement adaptive layouts (WindowSizeClass), migrate to type-safe Navigation Compose graphs, design cross-module Design Systems, wire complex screen-level state (MVI/MVVM), or orchestrate deep links and multi-screen workflows.
Identifies and implements micro-level Kotlin, Jetpack Compose, Coroutine, and Room database performance optimizations. Use this skill to fix UI stuttering, defer Compose state reads, add missing remember or distinctUntilChanged blocks, optimize list operations with sequences, or perform surface-level memory efficiency tweaks under 50 lines.
Improves project modularity, organization, and clean architecture by moving misplaced files or packages. Use this skill to move cohesive classes together, fix wrong layer violations (e.g., UI models in the Data layer), clean up generic 'Utils' packages, extract interfaces to pure domain packages, and enforce feature-based or layer-based package structures.
Elevates the Jetpack Compose user interface through micro-UX improvements, animations, accessibility (a11y) fixes, and UI structural polish. Use this skill to extract hardcoded styles to AppTheme, add TalkBack semantics, implement AnimatedVisibility or micro-animations, extract stateless Composables, and add @Preview annotations.
Ensures the app runs efficiently and safely by handling memory management, state architecture, and Coroutine optimizations. Use this skill to fix memory leaks (OOM), optimize Coroutine dispatchers, enforce immutable StateFlow architectures, add database indexes, or resolve Compose state bottlenecks.
Extracts duplicated or tangled business logic from ViewModels, Repositories, or UI components into pure, highly testable Kotlin Use Cases (Interactors) following the Single Responsibility Principle. Use this skill to decouple Android dependencies from business rules, create domain-layer interactors, or reduce ViewModel bloat.
Optimizes Gradle build scripts, compilation times, and Android Studio sync performance. Use this skill to migrate kapt to ksp, fix Gradle Configuration Cache violations, extract build logic into precompiled script plugins, or tune gradle.properties for better JVM and parallel execution.
Removes app bloat, secures data, and ensures failures are visible. Use this skill to safely eliminate dead code or unused resources, secure vulnerabilities like hardcoded API keys, fix silent exceptions (empty catch blocks), convert heavy assets to WebP, and ensure logs do not contain PII.
