On the possibilities and limitations of LLM-based multi-agent systems for multi-criteria decision-making in healthcare operations management

The paper proposes a framework to evaluate the reliability of large language model (LLM) agents when they generate stakeholder preferences for multi‑criteria decision‑making in healthcare operations. It examines both explicit preferences—agents rating the importance of patient waiting time, provider workload, and operating cost in an outpatient scheduling scenario—and implicit preferences—agents’ pairwise choices between emergency department configurations. Experiments show that explicit preferences vary by role and operating conditions, but deliberation can homogenize them, while implicit preferences are heavily influenced by presentation order and only modestly improved by contextual models. Robust weighted‑sum optimization models that incorporate preference uncertainty often yield different schedules than those based on average weights, underscoring the need for auditing LLM‑generated preferences before using them in healthcare decision support.

Frozen Models, Evolving Expertise: Model-Agnostic Learning from Deployment Experience for Multimodal Medical AI

The paper introduces a model‑agnostic framework that lets frozen large language models (LLMs) and vision‑language models (VLMs) learn from deployment experience without retraining. It does so by adding three external expertise components—a Skill for guiding reasoning and tool use, a Knowledge Memory for storing reliable facts, and a Multimodal Knowledge Base for visual examples—and by using a validation strategy that updates only when new cases improve performance without harming past performance. Experiments on six benchmarks with both open‑weight and closed‑source models show up to a 34.2% performance gain on medical tasks, generalization to unseen cases, and transferability to other models and non‑medical domains.

Algorithmic Primitives of Theory of Mind Benchmarks

The paper questions whether Theory of Mind (ToM) benchmarks truly assess theory of mind or merely test parsing and algorithmic state tracking. It introduces PDDL-Mind, a neuro‑symbolic method that parses narratives into the Planning Domain Definition Language (PDDL) and executes candidate actions using predefined update algorithms, yielding program‑verified state traces. Experiments on MMToM, MuMA, and FanToM show that delegating parsing to programs and state tracking to PDDL significantly improves performance, suggesting that current benchmarks mainly penalize unreliable implicit state tracking rather than genuine belief or counterfactual reasoning.

Quoting Addy Osmani, Morgan Westlee Lunt, and Qing Wang

The article discusses a shift in code review practices, moving from a final gate to continuous review that functions like spellcheck during coding. It highlights how the Claude Code team uses the Claude AI to catch routine mistakes before human reviewers intervene, allowing developers to focus on higher-level issues. The piece references insights from Addy Osmani, Morgan Westlee Lunt, and Qing Wang on this evolving approach.
