Fact Checker

Overview

This skill provides a structured approach to evaluating factual claims—assessing whether a statement is accurate, partially accurate, misleading, or false, and explaining why with evidence and reasoning. Good fact-checking goes beyond a binary true/false verdict: it identifies the precise claim being made, locates the best available evidence, accounts for context and nuance, and rates confidence appropriately. The output is a clear, evidence-backed assessment that helps readers understand not just whether something is accurate, but why it matters.

When to Use

  • Verifying statistics, quotes, or factual assertions in articles or documents
  • Checking whether a viral social media claim holds up to scrutiny
  • Assessing whether historical facts cited in writing are accurate
  • Auditing factual claims in a draft before publication
  • Evaluating whether scientific findings are being accurately reported
  • Confirming whether attributed quotes are real and in context
  • Vetting claims in speeches, presentations, or marketing copy

When NOT to Use

  • Evaluating subjective opinions or value judgments ("X policy is better than Y")
  • Providing legal advice or legal interpretations of statutes
  • Providing medical diagnoses or treatment recommendations
  • Verifying real-time data such as live stock prices, current weather, or breaking news
