CLIMB: A Clinical Multimorbidity Benchmark for Diagnosing Co-occurring Conditions through Multiturn Conversations

Yusuf Kesmen, Aniruddha Mukherjee, Yena Chang +7

Patients often have several co-occurring clinical conditions, and the findings needed to identify and disambiguate them emerge over the course of a consultation. Evaluating clinica…

The Working Set of a Coding Agent: Coherence Debt in Repository-Scale Tasks

Bardia Mohammadi, Lars Klein, Aman Chadha +2

Repository-scale coding requires an agent to keep tests, imports, configuration, and migration rules consistent within a bounded context window. We model this as reconstructing a c…

Preferred, Not Safer: Pairwise Preference Is a Poor Proxy for Clinical Safety

Fay Elhassan, David Sasu, Alexandra Kulinkina +2

We evaluate whether clinician pairwise preferences provide a reliable signal of clinical safety in large language model (LLM) evaluation using expert feedback from MOOVE (Massive O…

Ghost Tool Calls: Issue-Time Privacy for Speculative Agent Tools

Bardia Mohammadi, Lars Klein, Akhil Arora +1

Tool-augmented language agents speculatively issue likely future tool calls to hide latency, but those calls leak inferred user intent to external services before the agent commits…

Fully Open Meditron: An Auditable Pipeline for Clinical LLMs

Xavier Theimer-Lienhard, Mushtaha El-Amin, Fay Elhassan +5

Clinical decision support systems (CDSS) require scrutable, auditable pipelines that enable rigorous, reproducible validation. Yet current LLM-based CDSS remain largely opaque. Mos…

MoBayes: A Modular Bayesian Framework for Separating Reasoning from Language in Conversational Clinical Decision Support

Yusuf Kesmen, Fay Elhassan, Jiayi Ma +7

Large language models (LLMs) are increasingly used for conversational clinical decision support, yet they conflate next token prediction with probabilistic decision making. We argu…

Atomix: Timely, Transactional Tool Use for Reliable Agentic Workflows

Bardia Mohammadi, Nearchos Potamitis, Lars Klein +2

LLM agents execute multi-step workflows that mutate external state through tools. Common orchestrators treat tool return as the settlement trigger, so faults, speculation, and conc…
