Codex adds /goal for autonomous testing

The introduction of the /goal command marks Codex's transition from a passive, chat-based coding assistant to a fully autonomous engineering collaborator that runs self-correcting QA loops.

• –Developers can offload the tedious aspects of QA by letting Codex auto-generate user stories directly from the codebase and track verification status in real time.
• –The agentic harness allows the model to run tests, capture stack traces, and iteratively modify code until all defined features are validated.
• –Shifting developer workflows from manual editing to writing validators and checks will significantly speed up release cycles for small teams.
• –While highly efficient for standard user flows, the system's success relies heavily on high-quality specifications to avoid hallucinated test assertions.
