Kotlin development plugin with practical skills for idiomatic language design, coroutines and Flow decisions, Kotlin testing workflows, and kotlin-lsp-assisted editing.
npx claudepluginhub ririnto/sinon --plugin kotlinDesign Kotlin coroutine and Flow APIs with explicit ownership, honest async semantics, and cancellation-safe behavior. Use this skill when the user asks to "use coroutines", "design a suspend API", "choose Flow vs suspend", "debug cancellation", "review Kotlin async code", or needs guidance on Kotlin coroutine and Flow patterns.
Write idiomatic Kotlin with null safety, value types, extensions, collections, string handling, and standard-library boundary choices. Use this skill when the user asks to "write idiomatic Kotlin", "refactor Java to Kotlin", "use Kotlin null safety", "choose data class vs sealed class", "use Kotlin serialization", "model Path or date-time values in Kotlin", "choose collection vs sequence", "use scope functions", "use runCatching or Result", "parse text with Regex", or needs guidance on Kotlin language and standard-library patterns.
Write clear, deterministic Kotlin tests that prove one observable behavior with the smallest correct scope. Use this skill when the user asks to "test Kotlin code", "write a coroutine test", "mock a Kotlin dependency", "structure Kotlin tests", or needs guidance on practical Kotlin testing patterns.
