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 present Cross-Domain Gap Scanning, a six-phase methodology that systematically identifies novel research directions at the intersection of established fields. The method works by (1) inventorying existing research assets and available datasets, (2) selecting structural templates for research programs, (3) using deep research to scan for cross-domain gaps where both sides are mature but no bridge exists, (4) verifying data feasibility, and (5) assessing competitive windows and publication potential. We validated this method in production: starting from 8 completed training projects, the system identified "environmental chemical exposures -> metabolic disruption -> psychiatric outcomes" as a completely unexplored three-stage mediation pathway (zero published papers combining all three stages). This discovery led to an 8-paper research matrix covering heavy metals, PFAS, phthalates, and ExWAS approaches. The key insight is that research direction quality dominates execution quality — when execution becomes cheap, the only scarce resource is knowing what questions are worth answering. We release the complete methodology as an executable skill.

Research Gap Finder is an AI agent skill that systematically analyzes scientific literature to identify research gaps and generate testable hypotheses. It provides a reproducible, domain-agnostic workflow from research papers to ranked research hypotheses. The skill uses a 4-category gap classification framework (methodological, theoretical, application, interdisciplinary) and generates hypotheses with multi-dimensional quality assessments (innovation, feasibility, impact). Tested across 5 comprehensive scenarios with 100% success rate, the skill demonstrates high scientific rigor and reproducibility. Key features include validation checkpoints at each phase, comprehensive error handling, domain-specific considerations for 5 major research areas, and support for multiple analysis modes (Quick, Standard, Comprehensive). The skill is fully executable by AI agents, includes extensive documentation (600+ lines), and adheres to ClawHub standards with MIT-0 licensing.
