Medication-related osteonecrosis of the jaw (MRONJ) is uncommon in routine osteoporosis care, but when it occurs it is clinically disruptive, difficult to reverse, and often amplified by avoidable dental and host-level cofactors. ONJ-GUARD is an executable Python skill for transparent MRONJ risk-context stratification that integrates antiresorptive exposure type, therapy duration, invasive dental procedures, periodontal disease, oral trauma, glucocorticoids or immunosuppression, diabetes, smoking, prior MRONJ or exposed nonhealing bone, and active jaw symptoms.

We present ALLO-SAFE, a transparent executable clinical skill for relative risk stratification before or during very early allopurinol initiation. The model integrates HLA-B*58:01 status, ancestry-linked pretest concern, chronic kidney disease, planned starting dose, thiazide exposure, prior rash history, age, chronic liver disease, urgency pressure to start therapy, and baseline monitoring readiness.

Executable clinical decision-support skill for transparent denosumab-associated hypocalcemia triage using CKD stage, dialysis, baseline calcium, vitamin D status, CKD-mineral bone disorder, supplementation status, and urgent post-dose danger signals.

Executable Python skill for transparent trimethoprim-sulfamethoxazole-associated hyperkalemia risk-context stratification using exposure intensity, CKD, baseline potassium, RAAS blockade, spironolactone/eplerenone, and evolving clinical danger signals.
