SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes assets (resource) components.

What problem does it solve?

Doublecheck reduces the risk of relying on AI-generated content by extracting verifiable claims, locating supporting or contradicting sources, and flagging hallucination patterns so humans can independently verify results before acting.

Core Features & Use Cases

  • Three-layer pipeline: self-audit claim extraction, targeted web-source verification, and adversarial review for hallucination patterns.
  • Inline and full reporting: fast inline verification summaries for active mode and full templated three-layer reports on demand or for high-risk content.
  • Use Case: Validate assistant responses that include statistics, legal citations, or technical claims before publishing or using them in decision-making.

Quick Start

Run doublecheck on the assistant's previous response and produce an inline verification summary with confidence ratings and source links.

FAQPage Schema
How do I verify AI-generated text for factual accuracy before publishing?

Verifying AI-generated text involves extracting verifiable claims, running targeted web searches for supporting or contradicting primary sources, and applying adversarial hallucination checks to generate inline summaries or full reports with confidence ratings.

What is the best way to detect hallucinations in AI research summaries?

Hallucination detection in AI research summaries uses an adversarial review layer that cross-references extracted claims against located primary sources, flagging hallucination patterns so humans can independently verify the results before acting.

Can I fact-check legal citations and technical claims from conversational assistants?

Yes, fact-checking legal citations and technical claims from conversational assistants is possible using a three-layer verification pipeline that extracts claims, locates supporting or contradicting sources, and flags hallucination patterns for decision-making.

How does claim extraction work for fact-checking AI outputs?

Claim extraction for fact-checking AI outputs works by isolating verifiable statements from generated text, which enables targeted web searches to find supporting or contradicting primary sources for each specific extracted claim.

Does verification reporting provide inline summaries or full reports?

Verification reporting provides both fast inline verification summaries with confidence ratings for active mode and full templated three-layer reports on demand, specifically for validating high-risk content like legal or technical analyses.
