GEO Trust-Signal / Claim Provenance Auditor

The GEO Trust-Signal / Claim Provenance Auditor is a free Claude Skill that detects numerically-specific claims (dollar amounts, percentages, bulletin/model codes) lacking inline sourcing, plus Person schema completeness checks, generalizing MV3's own internal claim-guard pattern into a portable skill.

What this is (and isn’t)

A text and schema scanner over content you supply, not a hosted service or a live fact-checker, it flags claims lacking a nearby source, it does not verify whether a sourced claim is actually true.

Where this pattern comes from

MV3 already runs this exact discipline internally on the atvshop project (R-135): numerically-specific claims must have a verified source URL or they get stripped from render. This skill generalizes that same enforcement into a portable, reusable tool for any content.

FAQ

Is this skill free to use?

Yes. Free to download and run yourself. MV3 charges $175/hr only for implementation help wiring this into your real CMS publish pipeline.

What claim types does this detect?

Dollar amounts, percentages, bulletin/model-code patterns, and specific-count claims like "1,200 customers."

What counts as "sourced"?

A real URL appearing within 200 characters of the claim in the text. Configurable in the source.

Does this verify claims are true?

No, and the docs say so directly. It flags claims lacking a nearby source; it does not fact-check sourced claims.

Does my content get sent to MV3?

No. Scanning runs entirely in your own environment.
