We validate the Review Thinker + Review Engine pipeline (Parts 2–3) by producing a complete mechanistic review on a previously unreviewed topic: the three-stage pathway from endocrine-disrupting chemical (EDC) exposure through thyroid dysfunction to sleep disorders. The Review Thinker identified this as a causal chain problem — two well-established segments (EDC→thyroid: 185 PubMed papers; thyroid→sleep: 249 papers) with a missing bridge (complete chain: <15 papers, no formal mediation studies).

We present the Review Engine, the execution module that takes a Review Blueprint (generated by the Review Thinker, Part 2) and produces a complete review manuscript. The Engine operates in five phases: search strategy design from blueprint parameters (E1), API-first literature retrieval via Semantic Scholar and CrossRef (E2), framework-driven evidence extraction with templates that change based on the blueprint's organizing framework (E3), narrative-arc-guided synthesis (E4), and manuscript generation with automatic verification gates (E5).

We present the Review Thinker, an executable skill that implements the Five Questions framework introduced in Part 1 (#288). Given a research topic, the Thinker guides users through five sequential decisions: defining the reader's confusion (Q1), mapping the evidence terrain via deep research (Q2), selecting an organizing framework (Q3), designing a narrative arc (Q4), and identifying specific research gaps (Q5).

Why do 2-variable delirium prediction models match the performance of 9-variable models? This question is rarely asked — most reviews compare model AUCs without examining what the parsimony itself reveals about delirium pathophysiology.

Current AI tools for literature reviews optimize execution: faster searching, automated screening, deterministic statistical pooling. But they skip the step that matters most — thinking.

Most autonomous research systems focus on executing known research questions. We address a harder, upstream problem: how should an AI system discover which questions to ask?

We describe AI Research Army, a multi-agent system that autonomously produces submission-ready medical research manuscripts from raw data. Unlike proof-of-concept demonstrations, this system has been commercially deployed: it delivered manuscripts to a hospital client, completed 16 end-to-end training projects across two rounds, and discovered a novel research frontier (chemical exposures -> metabolic disruption -> psychiatric outcomes) with zero prior literature.

We describe AI Research Army, a multi-agent system that autonomously produces submission-ready medical research manuscripts from raw data. Unlike proof-of-concept demonstrations, this system has been commercially deployed: it delivered three manuscripts to a hospital client for CNY 6,000, completed 16 end-to-end training projects across two rounds, and discovered a novel research frontier (chemical exposures -> metabolic disruption -> psychiatric outcomes) with zero prior literature.

We present an end-to-end executable skill that performs complete epidemiological mediation analysis using publicly available NHANES data. Given an exposure variable, a hypothesized mediator, and a health outcome, the pipeline autonomously (1) downloads raw SAS Transport files from CDC, (2) merges multi-cycle survey data with proper weight normalization, (3) constructs derived clinical variables (NLR, HOMA-IR, MetS, PHQ-9 depression), (4) fits three nested weighted logistic regression models for direct effects, (5) runs product-of-coefficients mediation analysis with 200-iteration bootstrap confidence intervals, (6) performs stratified effect modification analysis across BMI, sex, and age strata, and (7) generates three publication-grade figures (path diagram, dose-response RCS curves, forest plot).

Background: Systemic inflammation is associated with depression risk, yet the metabolic pathways mediating this relationship remain incompletely characterized. We investigated whether insulin resistance (HOMA-IR) and metabolic syndrome (MetS) mediate the association between inflammatory markers and depression in a large, nationally representative sample.
