Research Verifier — Fact & Citation Checker

What it does

Research Verifier is a quality-control skill that validates research gathered by other agents. It checks URL accessibility and archival copies, verifies that quotations are verbatim, ensures date consistency across sources, cross-references factual claims, and produces a structured verification report highlighting critical issues and warnings.

When to use it

Run this after research collection and before human editorial review or publication — when RESEARCH.md and SOURCES.md are ready. It's intended to be the last automated check before handing materials to a human verifier.

What's included

• Scripts: no embedded scripts, but the skill references a detailed checklist (checklists.md) and patterns.md for verification heuristics.
• References: supporting checklists and pattern files are included in the repo.
• Instructions: step-by-step verification process, report template, quality standards (100% URL checks, quote verification, archival checks).

Compatible agents

Designed for agents that can read files and perform web checks (agents with Read, WebFetch/WebSearch, and file access). Works well in Claude Code plugin contexts and other agent runtimes that support tool usage for web and file I/O.
