Fact-check articles, posts, news and AI-synthesized content before publication: claims, quotes, studies, URLs and laundered citations. Use to fact-check, verify claims or sources, check accuracy, verify citations, validate references, or audit AI-summarized content.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fact-Check Process for Articles and AI-Synthesized Content A repeatable process for verifying the factual accuracy of articles, blog posts, news and AI-synthesized content before publication. It is calibrated for recursive contamination: AI output now feeds the sources the next AI and the next researcher cite, so agreement among sources counts only when they are independent. [synthesis-content-quality](../synthesis-content-quality/SKILL.md) covers style and substance; this skill covers factual correctness. ## Binding rules Rule numbers are the section numbers that other files cite as "SKILL.md section N" (section 2, 4a to 4g, sections 7 and 8). Contents names the file that holds each section in full. 1. **Extract every verifiable claim before verifying any:** numbers, studies, authors, dates, quotes, organizations, causal and comparative claims, URLs, DOIs, nested attributions. Claims that "sound right" are often the subtly wrong ones. 2. **Agreement counts only among graph-independent sources.** Sources that trace to one AI-generated upstream, or to the author's own doctrine, are single-sourced however many there are. …

How to install
mdr add synthesisengineering/synthesis-skills/synthesis-fact-checking@sha256:d928484b72e793caThe line at the top of this page pins the label v3.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
