에이전트 헬멧은 언어 모델 주위의 헬멧, 도구 및 제어 흐름을 지정하는 실행 가능한 코드입니다. 단일 글로벌 헬멧은 다른 실행 전략을 필요로하는 이질적인 작업과 싸울 수 있습니다. 이 작업에서 우리는 객체 지향 헬멧 (OO-Harness)을 소개합니다.이 작업은 객체 지향 디자인을 사용하여 실행 가능한 헬멧 클래스의 계층을 진화시키는 헬멧 최적화 프레임 워크입니다. 훈련 중에 진화 에이전트는 실행 기록을 사용하여 특수 헬멧의 가족을 만들고, 각각 기지의 하위 클래스 또는 기존 특수 헬멧을 통해 구현합니다.

Abstract

Agent harnesses are executable code that specifies the prompts, tools, and control flow around a language model. A single global harness can struggle with heterogeneous tasks that require different execution strategies. In this work, we introduce Object-Oriented Harness (OO-Harness), a harness optimization framework that evolves a hierarchy of executable harness classes using object-oriented design. During training, an evolution agent uses execution records to create a family of specialized harnesses, each implemented as a subclass of the base or an existing specialized harness via inheritance
