Expert checklist and prompts for auditing and fixing Android accessibility issues, especially in Jetpack Compose.

Expert guidance on setting up and maintaining a modern Android application architecture using Clean Architecture and Hilt. Use this when asked about project structure, module setup, or dependency injection.

Authoritative rules and patterns for production-quality Kotlin Coroutines onto Android. Covers structured concurrency, lifecycle integration, and reactive streams.

Guidance on implementing the Data Layer using Repository pattern, Room (Local), and Retrofit (Remote) with offline-first synchronization.

Production-ready scripts for Android app testing, building, and automation. Provides semantic UI navigation, build automation, log monitoring, and emulator lifecycle management. Optimized for AI agents with minimal token output.

Expert guidance on setting up scalable Gradle build logic using Convention Plugins and Version Catalogs.

Expert guidance on setting up and using Retrofit for type-safe HTTP networking in Android. Covers service definitions, coroutines, OkHttp configuration, and Hilt integration.

Comprehensive testing strategy involving Unit, Integration, Hilt, and Screenshot tests.

Best practices for implementing Android ViewModels using Kotlin 2.3+ Explicit Backing Fields, StateFlow for UI state, and SharedFlow for one-off events.

Expert guidance on using Coil for image loading in Jetpack Compose. Use this when asked about loading images from URLs, handling image states, or optimizing image performance in Compose.

Implement navigation in Jetpack Compose using Navigation 3. Use when asked to build state-driven navigation, manage back stacks, scope ViewModels, implement adaptive layouts, or migrate from Navigation Compose.

Audit and improve Jetpack Compose runtime performance from code review and architecture. Use when asked to diagnose slow rendering, janky scrolling, excessive recompositions, or performance issues in Compose UI.

Best practices for building UI with Jetpack Compose, focusing on state hoisting, detailed performance optimizations, and theming. Use this when writing or refactoring Composable functions.

Debug and optimize Android/Gradle build performance. Use when builds are slow, investigating CI/CD performance, analyzing build scans, or identifying compilation bottlenecks.

Kotlin Coroutines review and remediation for Android. Use when asked to review concurrency usage, fix coroutine-related bugs, improve thread safety, or resolve lifecycle issues in Kotlin/Android code.

Guide and execute the migration of asynchronous code from RxJava to Kotlin Coroutines and Flow. Use this skill when a user asks to convert RxJava (Observables, Singles, Completables, Subjects) to Coroutines (suspend functions, Flows, StateFlows).

Convert Android XML layouts to Jetpack Compose. Use when asked to migrate Views to Compose, convert XML to Composables, or modernize UI from View system to Compose.
