Production agents fail most often at the last mile of formatting, not reasoning

A builder argues that agents most often fail not at reasoning, but at the “last mile” of formatting. Real examples include unstable report section order, decks that bloat from five bullets to twelve slides, and summary messages whose structure is inconsistent enough that teams stop trusting them.
Their fix is to make formatting deterministic: have the model produce content into a fixed schema or template, then let a reliable non-agentic step render the final artifact. The point is that consistency matters more than demo flashiness in production, because people can only build habits around outputs that look the same every time.
