UnverifiedThe Agent Harness does not replace the reasoning capability of the core model, but instead builds a runtime management shell around the model, responsible for cross-cutting concerns such as tool invocation, state management, and error recovery.71% similarUnverifiedThe same model may perform worlds apart in a bare call versus an agent environment equipped with a full toolchain, and competition in AI programming is a contest of the collaborative capability between models and agent frameworks.68% similarVerifiedThe concept of Harness originates from Test Harness in software engineering, and in the AI Agent context it is extended to mean the systematic engineering that enables an Agent to run continuously, cyclically, and in a controlled manner68% similarUnverified面向客户的Agent只能依赖模型自主触发（model-invoked）的Skills，而无法依赖用户主动调用68% similarVerifiedAgents use the Tool Calling mechanism to allow models to output calling intent in a structured JSON format, with external programs executing the actual operations and feeding results back to the model.66% similar
