하네스 엔지니어링: 에이전트 우선 세계에서 Codex 활용하기

OpenAI's Harness Engineering project signals a radical shift toward Agent-First development, where engineers transition from writing logic to orchestrating AI agents through environment design and intent specification. This approach not only achieves unprecedented development velocity and code volume but also establishes a new paradigm where applications are built specifically for AI readability and automated feedback loops.
