Research Check

Performs three checks on an article: source verification, source gaps, and argumentation chain integrity.

1. Source Verification

For each cited source:

• Existence: Does the URL or reference actually exist? Use WebFetch to check live URLs.
• Accuracy: Does the source actually support the claim it is cited for? Read the relevant section.
• Attribution: Is the author/organization correctly named and the date correct?
• Hallucination check: Flag any source that cannot be verified or where the cited content does not match the article's claim.
