Harness Engineering: OpenAI's System Design Approach to AI Code Maintainability

This article analyzes OpenAI's Harness Engineering blog post, which advocates rigorous system design—context engineering, architecture constraints via CI/CD gates, and entropy combat—over reliance on better models to solve AI code maintainability, while noting high implementation costs and overlooked functional verification, contrasting with Anthropic's generator-evaluator approach.
