Harness engineering is a practice that improves agent output by shaping the environment around them through context and tools while keeping the model and coding agent constant. It encodes organizational nonfunctional requirements, local decisions, and process data into retrievable context, examples, and constraints that make agent work cumulative and coherent over time.
