SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Investigation helps you determine whether a claim is true by tracing where it came from, decomposing it into checkable parts, auditing the evidence behind it, generating rival explanations, and triangulating across independent sources.

Core Features & Use Cases

  • Source Trace: Identify the earliest origin of a claim and map how it may have changed through transmission, including source credibility and distortion points.
  • Claim Decomposition: Break complex claims into independently verifiable sub-claims, classify what’s assumed versus checkable, and prioritize what to verify first.
  • Evidence Audit: Assess evidence type, quality, strength, completeness, and conflicts of interest, highlighting what’s missing.
  • Counter-Hypothesis: Produce rival explanations that fit the same observations and specify distinguishing evidence or decisive tests.
  • Triangulation: Classify source independence and evaluate convergence or divergence to produce a reliability verdict.

Quick Start

Use the investigation skill to verify the claim you heard and request the best matching investigative workflow for tracing its origin, decomposing sub-claims, auditing evidence, and ruling out rival explanations.

FAQPage Schema
How do I fact-check a claim by tracing its origin and evaluating evidence?▼

Fact-checking a claim involves tracing its source origin, decomposing it into verifiable sub-claims, auditing supporting evidence, generating counter-hypotheses, and triangulating across independent sources to produce a reliability verdict.

What is triangulation and how does it work for verifying source reliability?▼

Triangulation classifies source independence and evaluates whether multiple independent sources converge or diverge on a claim, ultimately producing a structured reliability verdict based on evidence convergence.

How do I decompose a complex statement into independently verifiable sub-claims?▼

Decomposing a complex statement requires breaking it down into independently verifiable sub-claims, classifying what is assumed versus checkable, and prioritizing which specific components to verify first.

How can I generate counter-hypotheses to test rival explanations for the same data?▼

Generating counter-hypotheses produces rival explanations that fit the same observations and specifies distinguishing evidence or decisive tests to rule out alternative explanations during an investigation.

When should I use an evidence audit for claim verification?▼

Use an evidence audit when assessing evidence type, quality, strength, completeness, and conflicts of interest to determine whether the supporting evidence behind a claim is strong enough.
