Harness engineering: Leveraging Codex in an agent-first world

OpenAI shares lessons from building a real internal product with Codex-generated code.

OpenAI describes an internal experiment where Codex generated an entire product codebase from an empty repository. The post argues that engineers shift from writing code to designing environments, constraints, documentation, and feedback loops. Key practices include repo-local knowledge, mechanical architecture enforcement, agent-readable UI and observability, lightweight PR flow, and continuous cleanup.
