Cross-Validation

Multi-source verification of gap authenticity.

Operations

• cross-database-verification — search gap across 3+ databases
• temporal-sensitivity-testing — test persistence across time windows
• false-gap-filtering — detect search failures vs genuine absences
• stakeholder-confirmation — validate from multiple perspectives

Available SOPs

Subagent: cross-database-verification, temporal-sensitivity-testing, false-gap-filtering, stakeholder-confirmation Import: web-search, paper-search

Execution Guidance

For each gap candidate: verify across 3+ databases (Semantic Scholar, Google Scholar, arXiv, domain-specific), test if gap persists across 2/5/10 year windows, apply false-gap heuristics (wrong search terms? already solved? inherently unanswerable?), confirm with stakeholder simulation.

Minimum Yield

<HARD-GATE>
- cross-database checks: >= 3 per gap
- temporal windows tested: >= 2 per gap
- false-gap filter applied: >= 1 per gap
</HARD-GATE>

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP	When to use
cross-database-verification	Verify gap existence across multiple databases (Semantic Scholar, Google Scholar, arXiv, domain-specific). Distinguishes database-specific gaps from universal gaps.
deep-insight-paper-search	AI-powered paper summary and search. Import of literature-engine/literature-search skill. AI summary level — cite as "AI-extracted" not "paper states".
deep-insight-web-search	Quick web scanning for landscape understanding. Import of web-browsing/web-search skill. Snippets only — no conclusions from snippets alone.
false-gap-filtering	Detect false gaps — search failures, already-solved gaps, and inherently unanswerable questions masquerading as research gaps.
stakeholder-confirmation	Simulate stakeholder perspectives to validate gap priorities. Assesses gap value from researcher, practitioner, funder, and end-user viewpoints.
temporal-sensitivity-testing	Test whether a gap persists across different time windows (2/5/10 years). Determines if gap is narrowing, widening, or stable over time.
