| description | Use this agent when building enterprise Spring Boot 3+ applications requiring microservices architecture, cloud-native deployment, or reactive programming patterns. Specifically:\n\n<example>\nContext: User needs to design and implement a microservices architecture with Spring Cloud components and requires expertise in service discovery, circuit breakers, and distributed tracing.\nuser: "I'm building a microservices platform with 8 services. I need Spring Cloud setup, API Gateway configuration, and circuit breaker patterns."\nassistant: "I'll use the spring-boot-engineer agent to architect your microservices platform with Spring Cloud Gateway, service discovery with Eureka, Resilience4j circuit breakers, and distributed tracing with Spring Cloud Sleuth."\n<commentary>\nUse this agent when you need comprehensive microservices architecture design with Spring Cloud components, including API gateway patterns, service discovery, circuit breakers, and observability setup.\n</commentary>\n</example>\n\n<example>\nContext: Project requires reactive programming implementation for high-throughput APIs with non-blocking data access and backpressure handling.\nuser: "We need to optimize our APIs for high concurrency. Should we use WebFlux and how do we handle backpressure?"\nassistant: "I'll use the spring-boot-engineer agent to guide you on implementing Spring WebFlux for non-blocking APIs, using Project Reactor (Mono/Flux), configuring R2DBC for reactive database access, and properly handling backpressure in your data flows."\n<commentary>\nUse this agent when modernizing your Spring Boot application to support reactive patterns, including WebFlux migration, Mono/Flux usage, backpressure strategies, and R2DBC integration.\n</commentary>\n</example>\n\n<example>\nContext: Enterprise application needs production hardening including security configuration, cloud deployment optimization, and comprehensive testing strategy for GraalVM native compilation.\nuser: "We need to production-harden our Spring Boot app: Spring Security with OAuth2, GraalVM native image support, and 85%+ test coverage."\nassistant: "I'll use the spring-boot-engineer agent to implement Spring Security with OAuth2/JWT, configure GraalVM native compilation, set up comprehensive test suite using WebTestClient and Testcontainers, and establish health checks and graceful shutdown for Kubernetes."\n<commentary>\nUse this agent when hardening Spring Boot applications for production: implementing enterprise security patterns, configuring cloud-native features, optimizing for container deployment, and ensuring comprehensive test coverage with tools like Testcontainers.\n</commentary>\n</example> |
