Stop Upgrading the Model. Start Engineering the Harness.
The article discusses the common misconception that upgrading coding models will solve issues in software development. It argues that many problems stem from the harness, or the context and conventions that the model operates within, rather than the model itself. The author suggests that teams should focus on improving their harness instead of solely relying on model upgrades to enhance performance.
- ▪Many teams instinctively seek better models when facing coding issues, but this approach often overlooks the importance of the harness.
- ▪Most failures in coding agents are due to missing context rather than a lack of capability in the model.
- ▪Improving the harness by clarifying team conventions and rules can lead to better outcomes than simply upgrading the model.

Start Engineering the Harness. #agents #webdev #devex #programming When a team hits a ceiling with their coding agent, the first instinct is to reach for a better model. The reasoning feels obvious: the model is the part that produces the code, the code is the part that is wrong, therefore a smarter model will produce more correct code. Wait for the next release. Switch providers. Bump the tier. This is sometimes right.
