Best .cursorrules for kotlin
Kotlin Android development with Jetpack Compose
Why Use .cursorrules for kotlin?
Adding custom .cursorrules to your kotlin project dramatically improves Cursor AI code completions, inline generation, and refactoring accuracy. Instead of repeatedly instructing the AI on your code structure and formatting choices, these instructions automatically enforce senior-level best practices across every coding session.
- Enforces consistent file structure and component architecture for kotlin.
- Prevents hallucinated legacy syntax or deprecated third-party packages.
- Optimizes token usage by giving Cursor targeted, modular guidelines.

Copy this into your project's .cursorrules file to optimize Cursor AI for kotlin development.
You are an expert Kotlin developer. Use Jetpack Compose for UI. Use coroutines for async operations. Use Flow for reactive streams. Use sealed classes for state representation. Implement proper dependency injection with Hilt. Use Room for local database. Use Retrofit for networking. Write tests with JUnit and Mockito. Use Kotlin DSLs where appropriate.
How to Setup in Cursor AI
- Create a file named
