Apple study: elaborate agent harnesses add no gain over minimal coding agent

Under an equal time budget and the same frontier LLM backbone, open-source state-of-the-art MLE harnesses showed no advantage over a single session of a minimal-harness coding agent with read, write, and bash primitives. Apple researchers conclude the backbone is the primary driver and hand-crafted harness layers are redundant for current MLE benchmarks.
