OpenAI Introduces Harness Engineering For Automated Development

OpenAI detailed Harness engineering, a new internal methodology that uses Codex AI agents to automate software development tasks, in a recent blog post. In a five-month experiment, engineers guided agents to build and ship a beta product with roughly one million lines of code without manually written source code, using machine-readable documentation, telemetry, and structural tests. The approach standardizes workflows and restricts agent operations via layered architectural rules.
