    "body_text": "GLIDE tackles robot skills for which human teleoperators struggle to provide successful demonstrations. Given a task description and teleoperation code, it generates guardrails that filter commands, constrain likely failures and improve from trajectory feedback. In three tested tasks, the authors report that refined guardrails raised successful data collection from 0–10% to 70–90%. The guardrails are generated and evaluated within those experimental tasks; they are not a general proof that robot-generated safety rules can replace expert review.",
