This April-2026 Challenge aims to explore how LLMs orchestrate rule-based decision services. It describes three loosely coupled medical services:

• Determine Medication and Dosing
• Determine Creatinine Clearance
• Drug Interaction Rules

Your LLM should use these three services (instead of its own general “knowledge”) to determine a therapy for a patient with Acute Sinusitis. Here is a possible request: “I have a patient diagnosed with Acute Sinusitis. He is 58 years old, weighs 78 kg, and has a creatinine level of 1.85. Keep in mind that he is Penicillin-allergic and takes Coumadin.” Link
