Create Spring Boot Kotlin Project

Generates a complete Spring Boot Kotlin project skeleton with reactive dependencies, database connections, and local development infrastructure. Downloads the project template from Spring Initializr, adds SpringDoc OpenAPI documentation, configures R2DBC for PostgreSQL, Redis, and MongoDB with reactive drivers, then creates a docker-compose.yaml with all three services pre-configured. Saves you 20 minutes of boilerplate setup when starting a new reactive microservice. The generated project includes Testcontainers for integration testing and ArchUnit for architecture validation, so you get a production-ready foundation instead of just a bare Spring Boot template.
