This skill provides production-ready implementations for stateless authentication, role-based access control, and integration with modern authentication...

This skill provides systematic patterns for testing boundary conditions, edge cases, and limit values using JUnit 5. It covers numeric boundaries (Integer.MIN_VALUE, MAX_VALUE), string edge cases (null, empty, whitespace), collection boundaries, floating-point precision, date/time limits, and concurrent access...

To implement persistence layers with Spring Data JPA, create repository interfaces that provide automatic CRUD operations, entity relationships, query methods, and advanced features like pagination, auditing, and performance optimization.

SpringDoc OpenAPI is a library that automates the generation of OpenAPI 3.0 documentation for Spring Boot projects. It provides a Swagger UI web interface for exploring and testing APIs without writing additional configuration. This skill provides comprehensive patterns for integrating SpringDoc into Spring Boot 3.x...

Deliver feature-aligned CRUD services that separate domain, application, presentation, and infrastructure layers while preserving Spring Boot 3.5+ conventions. This skill distills the essential workflow and defers detailed code listings to reference files for progressive disclosure.

Implement optimal chunking strategies for Retrieval-Augmented Generation (RAG) systems and document processing pipelines. This skill provides a comprehensive framework for breaking large documents into smaller, semantically meaningful segments that preserve context while enabling efficient retrieval and search.

Implement Model Context Protocol (MCP) servers with Spring AI to extend AI capabilities with standardized tools, resources, and prompt templates using Spring's native AI abstractions.

This skill provides patterns for unit testing @Service classes using Mockito. It covers mocking all injected dependencies, verifying business logic, testing complex workflows, argument capturing, verification patterns, and testing async/reactive services without starting the Spring container.

This skill captures the dependency injection approach promoted in this repository: constructor-first design, explicit optional collaborators, and deterministic configuration that keeps services testable and framework-agnostic.

Resilience4j is a lightweight fault tolerance library designed for Java 8+ and functional programming. It provides patterns for handling failures in distributed systems including circuit breakers, rate limiters, retry mechanisms, bulkheads, and time limiters.
