fact-check

# fact-check The fact-check slash command verifies claims by decomposing them into components, searching primary and secondary sources, assessing each component's accuracy, and analyzing context. Use this command to evaluate the truthfulness of statements, verify information accuracy, identify misleading claims lacking proper context, and determine whether claims are supported by reliable evidence or contradicted by available sources.

Definition

fact-check.md

Fact-check the following claim: $ARGUMENTS

## Verification Process

### 1. Claim Decomposition
- Break the claim into verifiable components
- Identify key facts that need checking
- Note any ambiguities in the claim

### 2. Source Search
For each factual component:
- Find primary sources (official data, academic papers)
- Find secondary sources (reputable journalism)
- Look for counter-evidence

### 3. Verification Assessment
For each component, determine:
- **TRUE**: Strong evidence supports this
- **FALSE**: Strong evidence contradicts this
- **PARTIALLY TRUE**: Some aspects correct, others not
- **UNVERIFIABLE**: Cannot confirm with available sources
- **MISLEADING**: Technically true but lacks context

### 4. Context Analysis
- Is the claim missing important context?
- Is it outdated information presented as current?
- Are there caveats being omitted?

### 5. Source Quality Evaluation
Rate sources on:
- Authority (expertise of source)
- Recency (how current)
- Objectivity (potential bias)
- Corroboration (multiple sources agree)
