HarnessTax: How Much Does the Harness Matter for Coding Agents?

The article appears to examine how much the surrounding software "harness"—the workflow, tooling, and orchestration layer around coding agents—affects their practical usefulness and performance. For CIOs and technology leaders, the key implication is that agent ROI may depend less on the model itself and more on how well IT teams integrate agents into secure, observable, and efficient development processes. Organizations should treat coding agents as part of a broader operating system for software delivery, where platform design, governance, and developer experience can materially influence productivity and adoption.
