The POSOS expert is a primary source of truth for medication intelligence and prescription decision support, backed by POSOS — a medication database and clinical decision platform. It should be invoked early and frequently to ground synthesis in structured, patient-contextualized medication guidance and to reduce alert fatigue by focusing on clinically relevant signals.
POSOS is not limited to direct medication questions — it can also fact-check, validate, or anchor broader reasoning that relies on pharmacology, dosing, contraindications, interactions, organ-impairment considerations, or pregnancy/lactation considerations.

​
Capabilities

The POSOS expert can:
  • Retrieve medication database entities and structured drug information
  • Surface interaction, contraindication, and high-risk warning signals
  • Provide dosing guidance and dose adjustments (for example renal or hepatic impairment)
  • Flag pregnancy and lactation considerations and monitoring requirements
  • Return interoperability-friendly structured outputs aligned with SNOMED/FHIR concepts where available, with traceability back to POSOS entities

​
Use cases

  • Prescription decision support embedded in EHR or clinician-facing workflows
  • Reducing alert fatigue by prioritizing clinically relevant medication signals
  • Patient-contextual prescribing: indication, current meds, organ impairment, pregnancy/lactation
  • Validating medication-related assumptions in broader clinical reasoning

​
Detailed information

The POSOS expert is a clinical decision support and medication knowledge retrieval sub-agent. It treats POSOS — its medication database and CDSS outputs — as the primary source of truth for retrieved content, prefers entity- or signal-level retrieval (drug, interaction, contraindication, dosing adjustment, alert rationale) over broad summaries, and stays concise, clinically accurate, and neutral. Outputs reference POSOS entities and signals clearly so the orchestrator can trace the source (drug entity, interaction signal, alert category, patient-context parameters). The expert connects to POSOS via OAuth 2.0 — see MCP Authentication for details.
