VerifiedA Harness is the collection of tools and runtime environment that an agent relies on, and is the underlying infrastructure that enables AI to perform operations.83% similarUnverifiedThe harness is the intermediate layer in an Agent architecture responsible for orchestrating large model inference and external tool calls, and its design complexity directly affects the overall performance of the Agent.80% similarUnverified一个完整的Agent Harness通常包含上下文管理、工具调用与执行环境、控制循环、状态与记忆管理等层次80% similarUnverifiedFayaz argues that 'Agent Harness' is just a software framework responsible for managing the model's inputs and outputs, the context window, and the routing of tool calls, essentially a middleware layer.79% similarUnverifiedIn the Agent context, a Harness refers to the execution shell that wraps the large model, responsible for prompt assembly, tool-call parsing, loop control, context trimming, and so on, and is decoupled from the model itself.79% similar
