NSAID-associated acute kidney injury remains a common and preventable clinical problem, especially in older adults, chronic kidney disease, heart failure, cirrhosis, volume depletion, and the classic ACE inhibitor or angiotensin receptor blocker plus diuretic setting. We present NSAID-AKI, an executable Python skill for transparent NSAID-associated AKI risk-context stratification.

Lower gastrointestinal perforation during IL-6 blockade is uncommon but clinically serious, and tocilizumab has repeatedly been associated with higher rates of diverticulitis-related lower-GI perforation than several alternative biologic strategies in rheumatoid arthritis cohorts. We present TCZ-PERF, an executable Python skill for transparent risk stratification before or during tocilizumab use in rheumatic and autoimmune disease.

MMF-PREG is an executable clinical skill for transparent reproductive-safety triage around mycophenolate use in rheumatic and autoimmune disease. It addresses a real bedside problem: fetal-teratogenic exposure risk and preconception transition failure when patients remain on mycophenolate during possible conception, stop it without completed washout, or lack a pregnancy-compatible maintenance plan.

RTX-IGG is an executable clinical skill for transparent monitoring-oriented risk stratification of rituximab-associated hypogammaglobulinemia and infection vulnerability in rheumatic and autoimmune disease. The model integrates baseline and current IgG, IgM, rituximab course count, recency of dosing, maintenance intent, cyclophosphamide and glucocorticoid exposure, lymphocyte count, prior serious infection, chronic lung disease, kidney disease, and persistent B-cell suppression.

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.

LATAM-RX adjusts rheumatology clinical decision support for Latin American practice realities including TB burden, insurance formulary limitations (IMSS/ISSSTE), endemic infection screening, diagnostic delays, and access fragility. Four-domain composite with GLADEL/PANLAR/COPCORD references.

FLARE-BEFORE-FLARE models preclinical flare detection using wearable-derived digital biomarkers and patient-reported outcomes. Eight-domain personal z-score deviation with weighted composite scoring and pattern classification (inflammatory, musculoskeletal, fatigue-sleep).

RHEUM-POLYSHIELD aggregates retinal toxicity, glucocorticoid-induced osteoporosis, infection risk, and QT hazard flags into a unified safety profile for rheumatology patients under chronic immunomodulation. Four-domain weighted heuristic with text alerts.

LUPUS-DRIFT models systemic lupus erythematosus as a longitudinal trajectory problem integrating serologic activity, renal signals, treatment burden, and flare tendency with a Zamora-PCT bridge for infection-vs-flare differentiation. Literature-informed heuristic for transparent surveillance support.

SSc-COMPASS is a transparent multimodal risk-layering skill for systemic sclerosis integrating cutaneous subtype, serology, capillaroscopy, pulmonary physiology, HRCT burden, and cardiopulmonary markers. It classifies patients into ILD progression risk, vasculopathy risk, and PAH flag domains with weighted composite trajectory output.

Implements Cutolo et al. (2000/2004) classification system for nailfold videocapillaroscopy (NVC) in systemic sclerosis spectrum disorders.

Standalone Holter ECG analysis skill implementing synthetic ECG generation, Pan-Tompkins R-peak detection, time/frequency-domain HRV analysis (SDNN, RMSSD, pNN50, LF/HF), Bazett/Fridericia QTc computation, and drug-specific cardiac monitoring for rheumatologic medications (HCQ, HCQ+azithromycin, JAK inhibitors). Demo: 5-min recording with 359 beats, HR 72 bpm, SDNN 23.
