Consilium — A Multi-Agent Clinical Consult Mesh

THE PROBLEM Clinical triage and decision support is collaborative work. Intake, differential reasoning, medication safety, and escalation are different competencies, and the high-stakes cases are exactly the ones that need a human in the loop with a clear audit trail. Most "AI health assistant" demos collapse all of that into a single model behind a chat box — opaque, unauditable, and impossible to govern. WHAT WE BUILT Consilium is a multi-agent clinical consult mesh built on Band. Six specialized agents sit in one shared Band room and coordinate a triage entirely through Band's native @mention routing — there is no central dispatcher. The agents are deliberately built on THREE different frameworks and a MIX of LLMs: • Triage Coordinator — assigns 1 of 4 urgency levels • Diagnostician — confidence-scored differential • Medication Safety — drug-interaction screening • Clinical Guardian — escalation + recruitment authority • Care Scribe — clinician brief + patient summary • Cardiology Consult — recruited LIVE, not pre-added • On-Call Clinician — a HUMAN SAFETY BY DESIGN All data is synthetic and labelled as such. Every clinical output carries a decision-support disclaimer. High-stakes paths (emergent, low-confidence, or contraindicated-interaction) are routed to a human and never auto-decided. This is a decision-support demonstration, not a medical device. PROVEN, NOT MOCKED The clinical logic (triage rules, 79 curated drug interactions, condition KB) is pure, deterministic, and unit-tested — 50 passing tests, including a build test per agent that constructs each real Band Agent.
