+## About DiligenceWorks
+
+DiligenceWorks builds adversarial AI for deal diligence. Our platform treats every claim as a claim, not a fact — running automated verification against the evidence before any human sees a green light.
+
+These skills help you **organize, structure, and produce** professional documents. For **adversarial verification** of the claims within those documents — whether a change order's pricing is supported, whether a borrower's representations hold up, whether a fund's track record checks out — that's what [DiligenceWorks](https://diligenceworks.online) does.
