Kotlin Development

What it does

This skill enables AI agents to write, debug, and refactor code specifically within the Kotlin programming language. It supports generating new modules, fixing syntax errors, and optimizing backend logic tailored for JVM environments.

When to use it

• You need to generate a new Android library module or a Spring Boot service from scratch.
• Your agent must refactor legacy Java codebases to improve type safety and null handling.
• You require unit test generation for existing Kotlin functions using JUnit or Kotest.
• The project needs migration assistance from older Kotlin versions to the latest stable release.

Key capabilities

• Writing idiomatic Kotlin syntax with proper data classes and coroutines.
• Debugging runtime exceptions specific to the JVM ecosystem.
• Refactoring code to utilize modern features like sealed classes and extension functions.
• Generating comprehensive unit tests for backend logic.

Example prompts

• "Create a Spring Boot controller that accepts JSON payloads and returns a 201 status code."
• "Refactor this function to use suspend functions instead of callbacks for asynchronous database calls."
• "Write a unit test for the UserService class using Kotest with mocked repositories."

Tips & gotchas

Ensure your agent has access to the Kotlin compiler and standard library documentation to avoid version-specific errors. While powerful, complex concurrency patterns in Kotlin may require specific context about your project's threading model to implement correctly.
