LLM 에이전트의 동작 테스트, 능력 평가, 신뢰성 측정, 프로덕션 모니터링을 포함한 테스팅 및 벤치마킹 도구 모음입니다. 최고의 에이전트조차 실제 벤치마크에서 50% 미만의 성과를 보입니다.

mega-skills-collection란 무엇인가요?

이 기술은 LLM 기반 에이전트를 체계적으로 평가하고 벤치마킹하기 위한 포괄적인 프레임워크입니다. 행동 테스트, 능력 평가, 신뢰성 측정, 회귀 테스트 및 프로덕션 모니터링을 지원합니다. 주요 기능으로는 통계적 테스트 평가(여러 실행을 분석하여 신뢰 구간 계산), 행동 계약 테스트(에이전트가 미리 정의된 경계 내에서 동작하도록 보장), 적대적 테스트(취약점 탐지를 위해 에이전트를 의도적으로 공격)가 포함됩니다. 이 프레임워크는 다양한 LLM 에이전트 플랫폼(AgentBench, τ-bench, ToolEmu, Langsmith 등)에서 사용할 수 있도록 설계되었으며, 에이전트의 변동성과 예측 불가능성을 해결하는 데 중점을 둡니다. 개발자는 이 기술을 통해 에이전트의 성능을 정량화하고, 위험을 식별하며, 프로덕션 환경에 배포하기 전에 신뢰성을 개선할 수 있습니다.

패턴

통계적 테스트 평가

테스트를 여러 번 실행하고 결과 분포를 분석합니다.
