SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps identify potential hallucinations by tracing claims back to source materials and validating whether fetched information was actually used to support conclusions.

Core Features & Use Cases

  • Provenance tracing: Link each claim to verifiable sources and assess grounding.
  • Source mapping and confidence: Generate a structured report indicating source locations and confidence levels.
  • Gap analysis: Identify unbacked assertions and provide remediation steps.
  • Use Case: When evaluating responses, run the /hallucination-check to verify grounding against referenced documents.

Quick Start

Invoke the /hallucination-check command with the text you want validated to begin provenance verification.

FAQPage Schema
How do I detect hallucinations in AI generated text?

To detect hallucinations in AI generated text, you trace claims back to source materials and validate whether fetched information actually supports the conclusions. This process involves claim extraction, source mapping, and provenance reporting.

What is provenance tracking for fact-checking?

Provenance tracking for fact-checking is the process of linking each claim to verifiable sources and assessing its grounding. It generates a structured report indicating source locations and confidence levels to validate response accuracy.

How do I verify if a summarization is grounded in cited sources?

You verify if a summarization is grounded in cited sources by running a hallucination check that maps each extracted claim to its referenced document. This identifies unbacked assertions and provides remediation steps.

Can I identify unbacked assertions in QA workflows?

Yes, you can identify unbacked assertions in QA workflows by performing gap analysis on the response. This evaluates every claim against source materials to find ungrounded information and provide remediation steps.

What is the best way to trace claims to source documents?

The best way to trace claims to source documents is using provenance tracing to link each assertion to verifiable sources. This assesses grounding and generates a confidence report for content generation workflows.

Why does my AI response contain information not in the source material?

Your AI response contains information not in the source material due to hallucinations. Running a hallucination check performs gap analysis to identify these unbacked assertions and provides remediation steps.
