List all REST endpoints in the Spring Boot project — scans controllers and prints a route table

Start the Spring Boot application locally — checks prerequisites, then runs the app and reports startup status

Spring Boot expert — deep knowledge of Spring Boot, Spring Data JPA, Spring Security, Spring AI, and REST API design for Java 8+ projects

Use when the user asks to add caching, configure Redis or Caffeine cache, use @Cacheable/@CacheEvict/@CachePut, optimize repeated database or API calls, or review existing Spring Boot cache configuration.

Generates a complete Spring Boot CRUD feature (entity, repository, service, controller, DTOs, tests) in an existing project. Use when user asks to "add CRUD for", "generate entity", "create a feature for", "add REST endpoints for", "scaffold a feature", or "build CRUD for".

Reviews Spring Data JPA for N+1 queries, fetch strategies, projections, and Specifications. Use when user asks to "review JPA", "check for N+1", "JPA performance", "review my entities", "check fetch strategy", or "review my repositories".

Reviews Java logging for SLF4J best practices, MDC context, structured logging, and PII safety. Use when user asks to "review logging", "check my logs", "logging review", "is my logging correct", "MDC setup", or "check for PII in logs".

Generates or reviews OpenAPI / Swagger documentation for Spring Boot REST APIs — adds @Operation, @Schema, @ApiResponse annotations and configures Swagger UI. Use when user asks to "add Swagger", "document this API", "generate OpenAPI spec", "add @Operation annotations", "set up Swagger UI", or "document endpoints".

Use when the user asks to add resilience patterns, handle service failures, implement circuit breaker, retry, rate limiter, bulkhead, or timeout in a Spring Boot project using Resilience4J.

Scaffolds a brand-new Spring Boot project from scratch — build file, package structure, and a starter feature. Use when user asks to "create a new Spring Boot project", "bootstrap a project", "start a new project", "generate a new app", or "scaffold a new service".

Reviews or implements Spring Security configuration — JWT authentication, OAuth2, method-level security, CORS, and CSRF. Use when user asks to "add authentication", "secure this API", "implement JWT", "configure Spring Security", "add OAuth2 login", "protect endpoints", or "review security config".

Use when the user asks to add AI features, integrate Spring AI or LangChain4J, build a chatbot, implement RAG (retrieval-augmented generation), use vector stores, stream LLM responses, or call AI tools/functions in a Spring Boot project.
