Harness is the new code: why agent performance depends more on the runtime environment than the model
Trocar o modelo e manter o mesmo ambiente de execução raramente produz o salto que o marketing promete. O que muda o resultado, em muitos casos, é o conjunto que envolve o modelo: ferramentas disponíveis, regras de uso, memória de sessão, planejamento, subagentes, validações e o modo como o agente lê e escreve no repositório. Esse conjunto tem nome na literatura recente: harness. Dois trabalhos…
Two recent studies, "Beyond the Model: Demystifying Harness Effects in Software Engineering Agents" and "Harness Engineering: Anatomy, Architecture, and Evolution of Coding Agents", highlight the importance of the "harness" in software engineering agents. The harness refers to the set of tools, rules, and configurations that surround a model, and can have a significant impact on its effectiveness.
The studies found that a well-designed harness can lead to more stable and predictable results, while a poorly designed one can lead to failures. The harness is seen as a critical component in making software engineering agents reliable and efficient.
