android-kotlin-core
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-managementandroid-testing-unit
Workflow
- Map the request to the current Android stack, module boundaries, and minimum supported API level.
- Inspect the existing implementation for implicit assumptions, duplicate helpers, and outdated patterns.
- Apply the smallest change that improves correctness, readability, and long-term maintainability.
- Validate the result against the relevant showcase app path and repo benchmarks.
- Hand off adjacent work to the next specialized skill only after the core foundation is stable.
Guardrails
- Prefer official Android and Kotlin guidance over custom local conventions when they conflict.
- Keep public APIs boring and explicit; avoid clever abstractions that hide Android lifecycle costs.
- Do not mix architectural cleanup with product behavior changes unless the request explicitly needs both.
