Use when implementing Spring Boot 3.x applications. Provides hands-on implementation patterns for web, data, security, testing, and cloud-native development.
Review REST API contracts for HTTP semantics, versioning, backward compatibility, and response consistency. Use when user asks "review API", "check endpoints", "REST review", or before releasing API changes.
Use when designing, reviewing, or modifying REST API endpoints to enforce proper HTTP verbs, status codes, versioning, and API contract best practices.
Use when reviewing or writing code to enforce DRY, KISS, and YAGNI principles with Java-specific guidance.
Use when implementing or reviewing code that benefits from established design patterns like Builder, Factory, Strategy, Observer, Decorator, or Adapter.
