RubricsTree: Scalable and Evolving Open-Ended Evaluation of Personal Health Agents across Health Memory and Medical Skills
arXiv:2606.18203v1 Announce Type: new Abstract: The LLM-empowered personal health agents with user health (sensor) metrics have offered a promising pathway to alleviate global disparities in healthcare access. However, large-scale clinical deployment remains constrained by an open-ended evaluation bottleneck: physician annotation is reliable but costly and unscalable, while LLM-as-a-judge evaluators are scalable but subjective, inconsistent, and sometimes clinically misaligned. We introduce RubricsTree, a scalable evaluation framework with an expert-aligned hierarchical taxonomy of over 100 at
The proliferation of Large Language Models (LLMs) in healthcare necessitates robust, scalable, and clinically aligned evaluation methods as deployment moves beyond research into practical applications.
Reliable and scalable evaluation frameworks like RubricsTree are critical for safely and effectively integrating AI agents into sensitive sectors like personal health, ensuring efficacy and mitigating risks associated with misaligned or subjective assessments.
The ability to evaluate AI agents in open-ended, complex domains such as personal health, moves from a bottleneck constrained by unscalable human expert annotation or unreliable AI-as-a-judge approaches, towards a more standardized and scalable expert-aligned framework.
