Model-as-a-Harness
Model-as-a-Harness is an agent design paradigm in which an agentic operational scaffold is formalized as a machine-generatable artifact synthesized dynamically by a trained meta-agent. Rather than deploying foundation models within manually engineered, fixed harnesses, Model-as-a-Harness treats harness synthesis as a learned capability: the meta-agent generates, validates, and refines a customized four-module harness (governing memory, planning, action, and capability orchestration) at inference time, under which an arbitrary off-the-shelf foundation model executes.
