# Skill: Fact Checking

## Context
Codifies the challenger agent review output format and methodology so any agent performing fact-checking or review produces consistent, structured output.

## Pattern

### Review Methodology

For every claim or deliverable under review:
1. Ask: "What evidence supports this? What would disprove it?"
2. Generate counter-hypotheses and test them against available data
3. Verify URLs, package names, API endpoints, and external references actually exist
4. Flag confidence levels: ✅ Verified, ⚠<U+FE0F> Unverified, ❌ Contradicted
