SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes assets (resource) components.

What problem does it solve? AI-generated content often contains fabricated citations, invented statistics, and plausible-sounding errors that are hard to catch manually. This Skill systematically extracts every verifiable claim from AI output, finds independent sources, and flags hallucination patterns before you rely on the content. ## Core Features & Use Cases - Three-Layer Verification Pipeline: Extracts and categorizes claims (factual, statistical, citation, entity, causal, temporal), searches the web for supporting or contradicting sources, then runs an adversarial review targeting common hallucination patterns. - Two Operating Modes: Active mode embeds inline verification summaries into every substantive response, while one-shot mode runs a full verification on a specific text you provide. - Structured Verification Reports: Produces reports using a template with confidence ratings (VERIFIED, PLAUSIBLE, UNVERIFIED, DISPUTED, FABRICATION RISK), source links, and flagged items requiring attention. - Use Case: After receiving a legal analysis citing several court cases, invoke the skill to confirm each citation actually exists, check that holdings are described accurately, and receive a report highlighting any fabricated references. ## Quick Start Ask the AI to doublecheck the previous response and produce a full verification report with sources.

Frequently Asked Questions about doublecheck

FAQPage Schema
How do I verify AI-generated content for hallucinations?▼

Invoke the skill with the text you want checked, or activate persistent doublecheck mode. It extracts every verifiable claim, searches the web for sources, runs an adversarial review, and returns a report rating each claim from VERIFIED to FABRICATION RISK.

How to detect fabricated citations in AI output?▼

The skill treats citations as the highest-risk category. It searches for the exact case name, statute, or paper title, confirms the cited content matches the claim, and flags anything unfindable as FABRICATION RISK with an explanation.

What is the difference between active mode and one-shot mode?▼

Active mode runs continuously, embedding inline verification summaries after each substantive response. One-shot mode runs the full three-layer pipeline once on a specific text you provide and produces a complete verification report.

Does the verification work for legal and regulatory content?▼

Yes, legal content receives extra scrutiny including case citations, statutory references, and jurisdictional claims, and always triggers a full report rather than inline verification. However, results depend on web search coverage and may miss paywalled legal databases.

What are the limitations of automated fact-checking?▼

Web search may miss recent or paywalled sources, and the adversarial review uses the same underlying model that may have produced the original errors. A VERIFIED rating means a supporting source was found, not that the claim is definitely correct.
