This skill addresses the pain point of users struggling to quickly and objectively verify the authenticity of online information in the era of information overload. Whether it's rumors on social media, news flashes, or questionable data encountered in work or study, users often spend significant time cross-referencing various sources and are prone to subjective bias. This skill automates the process by integrating multiple authoritative and public sources, providing users with a neutral and efficient verification tool.
Usage is simple: you just need to make a request in the AI conversation, such as "Verify if this claim is true" or "Fact-check this news." The skill will then automatically deconstruct your query, gather information from sources like government sites, official media, fact-checking websites, X (Twitter), and Reddit based on a preset search strategy (prioritizing Tavily with fallback when necessary), and assess credibility using internal scoring rules. Finally, it presents the consolidated verification conclusion in a fixed four-part format (Correctness, Actual Situation, Conclusion, Relevant Links), with the entire process requiring no user intervention.
It is well-suited for teams or individuals who handle large volumes of external information and have high requirements for accuracy. This is especially true for content creators, social media managers, academic researchers, journalists, and any professional who needs to make decisions based on facts. For practitioners needing to quickly verify market rumors, competitor activities, or industry reports, this skill can significantly improve information screening efficiency and reduce the risk of being misled.
It is recommended to use this tool uniformly when you need to quickly fact-check public statements, news reports, or social media posts online. Note that it primarily verifies based on publicly available information and cannot cover non-public or paywalled content. In high-risk areas such as public safety, healthcare, and financial fraud, its assessments are more stringent, and users should still combine it with professional judgment.
Key Features
Unlike tools that rely solely on a single search engine or merely provide a list of links, it enforces a "Claim Core First" principle and a multi-source ratio strategy. It outputs a conclusion integrated through internal rule-based scoring (on a 100-point scale), rather than listing raw information, effectively preventing users from being misled by minor discrepancies.
Limitations
This skill heavily depends on the availability and quotas of external APIs (such as Tavily, Twitter CLI, Reddit CLI). While fallback mechanisms are triggered if APIs fail or quotas are exhausted, the breadth and depth of verification may be limited.
FAQ
Does this skill show me the internal score?
No. According to its core principles, external responses do not disclose the scoring mechanism or specific scores. It only provides the integrated conclusion (Correct/Incorrect/Partially Correct/Insufficient Evidence) and the relevant narrative.
Can it verify all types of information?
It primarily focuses on verifiable factual claims. For opinions, satire, or predictive information, it does not make true/false judgments but only compiles the currently verifiable situation. Assessments are more stringent for high-risk information involving areas like healthcare and finance.
