    "body_text": "Skill-space shooting searches for corrections through short reusable behaviors that a foundation model can select from a scene. Successful trials become new policy supervision rather than remaining a one-off agent plan. The authors report repeated autonomous improvement in real-world policies and show that skills can be shared across tasks to reduce new teaching. The abstract establishes the mechanism and reported pattern, but does not provide a universal success rate or remove the need to validate corrections on each robot and task.",
