FAQPage Schema
How do I automate fact-checking on a draft with factual claims?

To automate fact-checking, provide the path to your markdown draft file. The skill extracts factual claims, generates verification questions, and spawns an external claim-verifier agent to check them.

What is Chain-of-Verification and how does it work for academic research?

Chain-of-Verification (CoVe) is a fact-checking mechanism that extracts factual claims from text, generates targeted verification questions, and uses a separate claim-verifier agent to validate the information.

Can I fact-check numerical results and citations in markdown files?

Yes, you can fact-check numerical results and citations in markdown files by pointing the skill to your draft. It outputs a detailed report classifying each claim as supported, contradicted, or unverifiable.

Why does the claim verification process spawn a forked agent?

The claim verification process spawns a forked claim-verifier agent to prevent confirmation bias. This ensures the external agent evaluates the generated verification questions independently from the original text context.

How do I verify factual claims using a source pointer?

You can verify factual claims by running the skill with a source pointer or file path to your draft. The tool accepts markdown files and processes the text to extract and validate the claims within.

What are the limitations of automated claim verification for drafts?

Automated claim verification reports claims as supported, contradicted, or unverifiable. If the external claim-verifier agent cannot locate sufficient evidence, the claim is classified as unverifiable rather than false.
