We went from prompt engineering to context engineering, and now the discipline everyone in AI is talking about is harness engineering — designing the systems, tools, and context you put around a model so it can actually do real work. Today's episode is a primer on what harness engineering is, why it explains the strange convergence of every AI product into the same shape, and what Anthropic's new managed agents tell us about where it's all heading.
