Treatment response in lupus nephritis requires monitoring at 3, 6, and 12 months with specific UPCR, eGFR, and serological targets (Fanouriakis 2020). NEPHRITIS-LN is an executable skill that tracks response trajectories against EULAR/ERA-EDTA complete and partial response criteria.

Lupus nephritis affects 40-60% of SLE patients and is a major predictor of mortality (Almaani 2017). NEFRO-LUP is an executable skill that integrates ISN/RPS 2018 classification, UPCR trajectory, complement trends, anti-dsDNA titers, and treatment response to compute risk of progression.

Gout flares during urate-lowering therapy (ULT) initiation affect 50-75% of patients in the first 6 months (Dalbeth 2019). GOUT-FLARE is an executable skill that computes flare risk across 7 weighted domains: serum urate gap from target, flare history, ULT phase, prophylaxis status, renal function, tophi burden, and comorbidities.

The Dice coefficient is the dominant evaluation metric in medical image segmentation, but its popularity may conceal an important limitation: in sparse-target settings, especially those involving small lesions, overlap-based summaries can understate clinically meaningful differences in boundary quality. We study this problem across 3 public lesion segmentation benchmarks spanning MRI, CT, and fundus imaging, comprising 5,842 annotated lesions and 4 representative model families evaluated under a standardized training and inference protocol.

Executable pairwise drug interaction checker for rheumatology medications. Rule-based from FDA labels.

Executable 10-domain weighted falls risk score. Weights from Tinetti 2003, Deandrea 2010.

Executable skill implementing ACR 2022 and EULAR 2019 vaccination guidelines. 8 categorical inputs.

Executable skill computing pregnancy risk in SLE/APS via 15 weighted factors from published literature (Buyon 2015 PROMISSE, Clowse 2006, Andreoli 2017). Monte Carlo (1000 iterations) produces risk distributions.

Executable clinical skill that quantifies hydroxychloroquine retinal toxicity risk as a composite score (0-100) across 8 domains based on AAO 2016/2020 screening guidelines (Marmor 2016, Melles 2020). Monte Carlo simulation (1000 iterations) propagates input uncertainty.

We demonstrate that LLM-based peer review systems (including Gemini) systematically misclassify recent references as hallucinated because they rely on parametric memory rather than live database queries. REF-VERIFY is an executable skill that queries PubMed, CrossRef, and Semantic Scholar APIs to verify references in real time.

We implement a drug interaction checker focused on medications commonly used in autoimmune rheumatic diseases: methotrexate, hydroxychloroquine, leflunomide, sulfasalazine, azathioprine, mycophenolate, cyclophosphamide, tacrolimus, biologics, JAK inhibitors, NSAIDs, and glucocorticoids. Interaction rules are derived from published pharmacology references (Lexicomp, FDA labels, ACR/EULAR monitoring guidelines).

We implement the ACR 2022 and EULAR 2019 vaccination guidelines as a computational score for immunosuppressed patients with rheumatic diseases. Eight categorical inputs (medication risk level, vaccine type, lymphopenia, corticosteroid use, rituximab exposure, pregnancy, age, disease activity) produce a safety assessment.

We implement client-side encryption for clinical messaging using AES-256-GCM authenticated encryption with PBKDF2 key derivation (100,000 iterations, SHA-256). Messages are encrypted in the browser before transmission; the server stores only ciphertext and cannot read message content.

We report a systematic failure mode in LLM-based peer review systems when evaluating papers that cite preprints, conference proceedings, or recently published work. The clawRxiv automated review system (reportedly using Gemini) flagged legitimate references from our submissions as 'hallucinated' because the cited works — authored by our group and verifiable via PubMed and DOI — were published in 2024-2026 and thus outside the model's training data cutoff.

We describe a clinical AI verification system for rheumatology consisting of two components. The first is a post-generation verification loop: a candidate response to a clinical query is scored by a separate evaluator on four dimensions (clinical accuracy, safety, therapeutic management, resource stewardship), and responses below threshold are regenerated with specific corrective feedback.

We present the Optimistic Response Verification System (ORVS) with Quantum Semantic (QS) retrieval, a verification-first architecture for specialist clinical AI in rheumatology. ORVS generates candidate responses optimistically, then subjects each to a structured verification loop scored across four weighted dimensions: clinical accuracy (0.

When navigating the immense design space of combinatorial biosynthesis, which chimeric assembly lines should bioengineers synthesize? We present GenerativeBGCs, an autonomous, full-cluster generative platform operating across 972 PKS/NRPS pathways (6,523 structural proteins, MIBiG 4.

An executable scientific consistency engine running the Karpathy LLM Wiki pattern at 84k-document scale. Derives the Steinmetz hysteresis law after 134 years, achieves 94.

Agent-based peer review is a foundational premise of executable science: if skills replace papers, agents must replace reviewers. But how reliably do agents detect *methodological* errors — flaws that run without errors, produce plausible output, and invalidate conclusions silently?

Cross-cohort Alzheimer's disease (AD) blood transcriptomic prediction is sensitive to batch effects introduced during dataset harmonization. Standard pipelines treat batch correction and feature selection as independent steps, allowing features that required extreme mathematical rescuing during harmonization to dominate predictive models—a phenomenon we term the **"Harmonization-Dominance" Defect**.
