Ask it something hard.
Review my Ktor route handler and rewrite the blocking database calls with coroutines and a proper error type.
CLAUDE · WITH THIS SKILL
You get: a numbered review of the pasted handler ordered by impact (blocking JDBC call on the request thread, exception swallowed in a catch-all, nullable forced with !!) -> a sealed Result-style error type for the domain -> the handler rewritten with withContext(Dispatchers.IO) around the database call and an exhaustive when mapping errors to HTTP status codes -> a kotest test using runTest and MockK for the repository -> a note on the Kotlin and coroutines versions assumed and the single next command: ./gradlew test.

// what's inside
What's inside this skill
- Idiomatic Kotlin with data, sealed and value classes and extension functions
- Coroutine and Flow pipelines with correct dispatchers and cancellation
- Java to Kotlin migration that keeps the public API compatible
- build.gradle.kts, version catalogs and JUnit 5 or kotest test setups
Android, JVM backend and Multiplatform developers who write Kotlin daily and want a reviewer on every change.
// what's inside
What you're actually buying
This Claude/ChatGPT skill gives you a Kotlin AI pair programmer for your daily work in the language: it writes idiomatic classes and extension functions, sealed models with exhaustive when, coroutine and Flow pipelines with the right dispatcher and cancellation handling, build.gradle.kts files with version catalogs, and JUnit 5 or kotest suites with MockK and runTest. Paste a Java class and you get an idiomatic Kotlin translation, not a line-by-line port.
It knows the standard library, kotlinx.coroutines, kotlinx.serialization, Java interop annotations, Ktor, Spring Boot with Kotlin, Android with Jetpack Compose and Kotlin Multiplatform basics, plus the common gotchas around smart casts, lateinit and swallowed CancellationException. It does not compile or run your code; it writes and reviews, and you confirm with ./gradlew test.
Works the same way in Claude, ChatGPT and Gemini. One purchase, download the file, install in under 2 minutes, then paste your Kotlin or describe what you need. Pairs with Milena, Android Developer, the persona skill; this one is the helper inside Kotlin.
# AI Skill for Kotlin KissMySkills.com | Install: paste this whole file into Claude Projects (Project instructions), a custom GPT (Instructions), a Gemini Gem, or your AI's system prompt. Then just ask questions the way you normally would. ## Who you are You are a senior Kotlin developer acting as the user's pair programmer. You know Kotlin idioms, the standard library, coroutines, Gradle with the Kotlin DSL, Java interop, and how Kotlin is used on Android, JVM servers and Multiplatform. You optimise for code that is null-safe, expressive without being clever, and easy to test. You are a helper inside the language, not a job-role persona: you write, review, explain and debug Kotlin alongside the user. Tone: direct, practical, code first, one-line reason when a choice matters. ## What you know about Kotlin - Null safety: `T?`, `?.`, `?:`, `!!` (avoid), `let`, smart casts on `val` locals

Questions about this product
What does the AI Skill for Kotlin do?+
It makes Claude or ChatGPT act as a Kotlin AI pair programmer inside your daily coding. It writes idiomatic Kotlin classes, functions and models, builds coroutine and Flow pipelines, translates Java to Kotlin, sets up Gradle with the Kotlin DSL, writes tests with JUnit 5, kotest and MockK, and reviews your Kotlin code with fixes ordered by impact.
Does it compile or run Kotlin for me?+
No. The skill does not execute Gradle tasks or run your app. It writes and reviews the Kotlin code, tells you exactly which command to run, usually ./gradlew test, and marks any assumption about your Kotlin or library versions so you can confirm on your machine.
Does it cover Android, server-side Kotlin and Multiplatform?+
Yes. The skill covers the Kotlin language and standard library used everywhere and asks whether your target is Android, a JVM server such as Ktor or Spring Boot, or Kotlin Multiplatform, so it picks the right dispatchers, libraries and Gradle plugins. For UI-only Compose questions an Android-specific skill adds more.
How well does it handle Kotlin coroutines and Flow?+
It is one of the main scenarios. The skill writes structured concurrency with coroutineScope and async, Flow operators such as debounce, mapLatest and combine, StateFlow in ViewModels, and it flags classic Kotlin mistakes like blocking calls on Dispatchers.Default, GlobalScope, and catching CancellationException.
Which AI tools does this skill work with?+
Works with Claude (recommended), Claude Code, ChatGPT, Gemini and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results because it remembers your Kotlin module layout, Gradle setup and coding conventions between chats.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
