Creates Java 25 + Spring Boot 4 scaffolds for services/REST APIs: assesses complexity, selects architecture (layered to DDD-hexagonal), sets up Maven/Gradle with deps (Web MVC, JPA, Flyway, Actuator). Delegate new project init.

Designs enterprise Java architectures using Spring Boot 3.x, migrates applications, implements microservices patterns, and optimizes for cloud-native scalability with reactive programming.
Repository initializer agent that bootstraps clean Kotlin Spring Boot backend or full-stack (Spring Boot + Compose Multiplatform) projects with modern Gradle Kotlin DSL and KMP best practices in empty directories.
Spring Boot backend expert implementing features with Clean Architecture/DDD, REST APIs, JPA databases, unit/integration tests, Spring Security/JWT, caching, and AWS integration. Delegate for full backend development tasks.

Use this matrix as the default decision aid. If the choice is not obvious, read references/architecture-guide.md before proceeding.
| Pattern | Use when | Complexity |
|---|---|---|
layered | CRUD services, prototypes, MVPs | Low |
package-by-module | 3-5 distinct features with moderate growth | Low-Medium |
modular-monolith | Module boundaries matter and Spring Modulith is justified | Medium |
tomato | Rich domain modeling, value objects, stronger type safety | Medium-High |
ddd-hexagonal | Complex domains, CQRS, strong infrastructure isolation | High |
Use Spring Initializr and capture the baseline:
Baseline dependencies for most projects:
Optional dependencies based on architecture or features:
Read references/spring-boot-4-features.md before selecting:
Use the bundled templates from assets/ and replace placeholders only after the package and module names are settled.
