Android Kotlin Core

When To Use

• Use this skill when the request is about: kotlin cleanup in android app, convert verbose android java-style kotlin, sealed classes for ui state.
• Primary outcome: Use Kotlin idioms safely in Android apps, including nullability, data classes, sealed types, extension functions, and collection pipelines.
• Handoff skills when the scope expands:
• android-state-management
• android-testing-unit

Workflow

1. Map the request to the current Android stack, module boundaries, and minimum supported API level.
2. Inspect the existing implementation for implicit assumptions, duplicate helpers, and outdated patterns.
3. Apply the smallest change that improves correctness, readability, and long-term maintainability.
4. Validate the result against the relevant showcase app path and repo benchmarks.
5. Hand off adjacent work to the next specialized skill only after the core foundation is stable.
