We present MTX-LIVER, an executable Python skill for transparent liver-safety risk stratification before or during low-dose methotrexate therapy in rheumatic and autoimmune disease. The model integrates obesity, diabetes, known steatosis/NAFLD, alcohol exposure, chronic hepatitis B/C, baseline and current aminotransferases, albumin, platelet count, methotrexate weekly dose, treatment duration, cumulative dose, folate supplementation, concomitant leflunomide, and persistent transaminitis.

Janus kinase inhibitors are effective therapies for rheumatoid arthritis and other autoimmune diseases, but thrombotic safety concerns remain clinically important. We present VTE-JAK, an executable Python skill for transparent pre-treatment and treatment-review stratification of venous thromboembolism risk in patients being considered for JAK inhibitor therapy.

Executable clinical skill for steroid-induced hyperglycemia risk stratification using baseline glycemic vulnerability, glucocorticoid exposure burden, and host susceptibility in rheumatic and autoimmune disease.

Fibromyalgia overlap commonly inflates composite disease activity measures in rheumatoid arthritis and related inflammatory rheumatic disease, creating risk of unnecessary biologic or immunosuppressive escalation. We present FIBRO-OVERLAP, an executable transparent clinical skill that integrates subjective symptom burden, objective inflammatory markers, tender-to-swollen joint mismatch, optional 2016 fibromyalgia criteria support, and imaging context to estimate likely fibromyalgia-driven inflation of apparent inflammatory activity.

Thiopurines remain clinically useful across rheumatology and systemic autoimmune disease, but preventable myelotoxicity still occurs when pharmacogenetic risk, baseline blood counts, interacting medications, and monitoring readiness are reviewed separately instead of together. We present THIO-SAFE, a transparent 10-domain weighted bedside score for estimating near-term azathioprine myelotoxicity risk.

We present GI-BLEED-NSAID, a transparent 10-domain clinical decision-support score for estimating near-term upper gastrointestinal bleeding risk before or during NSAID therapy in rheumatic and autoimmune disease. The model addresses a common real-world problem: deciding when standard NSAID use is acceptable, when proton pump inhibitor gastroprotection or COX-2 selection should be prioritized, and when nonselective NSAIDs should be avoided because cumulative bleeding risk is too high.

ZOSTER-GUARD is an executable clinical decision-support skill for estimating herpes zoster reactivation risk before JAK inhibitor or biologic therapy in rheumatic and autoimmune disease. The model integrates diagnosis group, therapy class, steroid intensity, age, prior zoster, lymphopenia, multimorbidity, additional immunosuppressants, and recombinant zoster vaccination status into a transparent 0-100 weighted score with Monte Carlo uncertainty estimation.

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.
