LangChain4j를 사용하여 선언적 AI 서비스를 구축하기 위한 패턴을 제공합니다. LLM 통합, 챗봇 개발, AI 에이전트 구현 및 Java에서의 대화형 AI를 지원합니다. 인터페이스 기반 패턴, 어노테이션, 메모리 관리 및 도구 통합을 사용하여 타입 안전한 AI 서비스를 생성합니다. 최소한의 보일러플레이트로 AI 기반 Java 애플리케이션을 만들거나, 메모리를 가진 대화형 AI를 구현하거나, 함수 호출을 사용하는 AI 에이전트를 구축할 때 사용하세요.
이 스킬은 Java 개발자가 LangChain4j 라이브러리를 사용하여 선언적이고 타입 안전한 AI 서비스를 구축할 수 있도록 지원합니다. 인터페이스 기반 패턴과 어노테이션을 통해 LLM(대규모 언어 모델) 통합, 챗봇 개발, AI 에이전트 구현 및 대화형 AI를 최소한의 보일러플레이트 코드로 생성합니다. 주요 기능으로는 메모리 관리(대화 기록 유지), 도구/함수 호출 통합, 그리고 AI 서비스의 타입 안전성을 보장하는 코드 생성이 포함됩니다. Claude Code, Cursor, Codex와 같은 AI 코딩 도구에서 이 스킬을 사용하면 복잡한 AI 기능을 모듈화된 방식으로 Java 애플리케이션에 손쉽게 추가할 수 있습니다. 또한, SKILL.md 문서를 기반으로 AI 에이전트가 자동으로 적절한 패턴과 구성을 선택하여 개발자의 의도를 정확히 반영한 코드를 생성합니다.
