kotlin-fundamentals

What problem does it solve?

This skill helps teams standardize Kotlin development by guiding the creation of type-safe, idiomatic code that minimizes boilerplate and runtime errors.

Core Features & Use Cases

• Guides on Kotlin fundamentals: nullable types, data classes, sealed types, and extension functions.
• Covers core collections, coroutines, and functional patterns to build robust software.
• Provides concrete examples and references for rapid onboarding and consistent coding style.

Quick Start

• Read the Kotlin fundamentals SKILL.md sections for practical guidelines.
• Verify your Kotlin toolchain with kotlin -version and follow the references in references/ (types.md, oop.md, functions.md, collections.md, coroutines.md, error-handling.md, kotlin-versions.md).
• Practice by refactoring a small Kotlin snippet to adopt data classes, sealed interfaces, and safe calls; load the code into a Kotlin REPL or a script and run it.
