What problem does it solve? Documents making factual claims without sources are hard to trust and easy to challenge. Manually finding credible sources, verifying they support each claim, and formatting footnotes is slow and error-prone. ## Core Features & Use Cases - Claim Selection: Identifies the atomic factual claims a skeptical reader would challenge, scoped to the user's request or to claims the argument rests on. - Source Research: Searches the web and opens candidate pages, preferring primary sources, authoritative institutions, and reputable secondary reporting that match each claim's exact scope. - Footnote Insertion: Places Markdown footnote markers after supported claims and appends linked definitions at the document's end, preserving existing footnotes and flagging unsupported claims. - Use Case: You have a draft blog post citing statistics and dates. Run this Skill to verify each key claim against web sources and receive the same text with sourced footnotes appended. ## Quick Start Ask the assistant to fact-check the attached document and add Markdown footnote citations to its key factual claims using web sources.
