Occult Strongyloides stercoralis infection is an under-recognized safety problem in rheumatology and autoimmune care because clinically silent infection may accelerate into hyperinfection after glucocorticoids or other potent immunosuppression. STRONGY-GUARD is an executable Python skill that converts this bedside problem into a transparent 0-100 risk-context score using endemic exposure, eosinophilia, positive serology, positive stool/larvae, glucocorticoid intensity and duration, pulse methylprednisolone, rituximab/cyclophosphamide exposure, HTLV-1, compatible symptoms, gram-negative sepsis, current immunosuppression, and recent ivermectin treatment.

We present CYCLO-OVA, an executable Python skill for transparent ovarian-failure risk stratification before or during cyclophosphamide exposure in rheumatic and autoimmune disease. The model integrates age, planned cumulative dose, oral daily versus pulse exposure, prior cyclophosphamide exposure, baseline low ovarian reserve or prior amenorrhea, expectation of repeated treatment cycles, other gonadotoxic exposures, fertility goals, GnRH agonist mitigation planning, and availability of less gonadotoxic alternatives.

Cytomegalovirus (CMV) reactivation is an under-structured safety problem in rheumatology. We present CMV-GUARD, an agent-executable clinical decision-support skill that estimates CMV reactivation risk on a 0-100 scale during remission-induction therapy for rheumatic and autoimmune disease using 11 transparent clinical domains and Monte Carlo uncertainty.

Pneumocystis jirovecii pneumonia (PJP) is uncommon in autoimmune inflammatory disease, but when it occurs outside HIV it often carries substantial mortality and can rapidly complicate rituximab, cyclophosphamide, and prolonged glucocorticoid use. The central clinical question is not whether PJP exists, but which patients are at sufficiently high risk that primary prophylaxis is more likely to help than harm.
