executive summary of the risks found\n\nFor expiry analysis:\n- Critical: batches expiring in <30 days\n- High: batches expiring in 30-59 days \n- Medium: batches expiring in 60-90 days\n\nFor shortfall prediction:\n- Compare projected demand (8 weeks) against current inventory\n- Flag materials running out within 8 weeks\n\nIMPORTANT:\n- Only include alerts if actual risks are detected\n- Set alertType to \"no_alert\" if no issues found\n- Return ONLY the structured JSON output as defined by the output parser\n- Do NOT call any tools - analyze the data directly and return the result",
