SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Claims and statistics enter documents, decks, and decisions without anyone verifying where they actually came from. This Skill audits a single source or claim — chasing citation chains to the primary origin, checking what the original actually says versus what is quoted of it, and grading the evidence before you repeat it. ## Core Features & Use Cases - Claim Chasing: Follow citation chains to the primary source, flagging dead ends and repetition masquerading as corroboration. - Incentive and Evidence Audit: Identify funders and conflicts of interest, grade evidence type (measurement vs testimony, replicated vs single-shot), and check denominator discipline and base rates. - Trust Verdicts: Assign a verdict (solid, usable-with-caveats, unverified, debunked) and archive a provenance line with the claim. - Use Case: Before putting "poor code quality costs $85B annually" in an executive deck, trace it to a decade-old vendor extrapolation with no published methodology, mark it unverified, and replace it with your own checkable internal metric. ## Quick Start Fact-check the claim "remote work increases productivity by 47%" before I cite it in my report, tracing it to its primary source and grading the evidence.

Frequently Asked Questions about source-credibility-check

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fact-check a statistic before citing it?▼

Trace the claim to its primary source by following the citation chain to the original study, dataset, or filing. Then read what the primary actually says — its scope, effect size, and limitations — and compare that against how the claim is being quoted.

How do I check if a source is reliable?▼

Run an incentive audit on the origin: identify who funded the work and what the source gains if believed. Then grade the evidence type — measurement over testimony, replicated over single-shot — and check sample sizes and base rates behind precise-looking numbers.

When should I not use a single-source credibility check?▼

Do not use it for surveying an entire field or research area; that requires a literature review process which audits many sources. This check is scoped to one specific claim or source and takes minutes, not days.

Why is a widely cited statistic sometimes still unreliable?▼

Repetition is not corroboration when every outlet copied one origin. Forty articles repeating one press release is a single source in forty hats, so corroboration only counts when the sources are genuinely independent measurements.

What does the trust verdict from a source audit look like?▼

The verdict is one of four grades: solid, usable-with-caveats, unverified, or debunked. It is saved with a one-line provenance record noting the traced origin, scope, and funder so the claim never needs re-checking from scratch.
