Meta has introduced an experimental developer tool, Meta XR Operator, in the Meta XR SDK v205 release. This tool leverages AI agents to construct an automated testing loop, supporting control via natural language commands. It enables developers to complete testing without repeatedly wearing a headset, reducing repetitive operations by over 80%, enhancing development efficiency, and ensuring reproducible test results. However, the current version lacks audio analysis capabilities, and its accuracy in identifying dynamic effects and subtle visual defects still needs improvement. The official recommendation is to prioritize its use in static, deterministic scenarios such as interface layout and interaction logic.
