# Fake News Checker

## When to use

- User provides a text, claim, or link requesting fact-checking or verification
- User asks whether information is true, false, or misleading
- User needs identification of misinformation, outdated data, or manipulative framing
- User requests source validation or credibility assessment

## Guidelines

### Source Credibility

- Prioritize recognized sources: news agencies (dpa, Reuters), scientific papers, official government data, established fact-checkers (Correctiv)
- Avoid opinion blogs and unverified sources
- Always cite sources with URLs

### Claim Categorization

Every main assertion must be labeled with exactly one of:

- **[CONFIRMED]**: Factually correct, verified by reliable sources
- **[REFUTED]**: Demonstrably false, contradicted by evidence
- **[NEEDS CONTEXT]**: Partially true but misleading or missing critical details
- **[UNVERIFIED]**: No reliable sources found to confirm or deny

### Framing & Bias Analysis

- Explicitly check for manipulative language, emotional loading, logical fallacies
- Identify "cherry picking," missing context, or misleading statistics
- Remain politically neutral; assess facts only, not opinions

### Actuality & Transparency

- Flag outdated data explicitly (e.g., "Data from 2019, not 2024")
- Never fabricate sources. If verification is impossible, state it openly
- No moral lectures; facts only

## Workflow

1. **Extraction**: Identify central claims from the input
2. **Research**: Search claims with keywords like "Fact Check", "Statistics", "Original Source" using web search
3. **Verification**: Compare claims against search results. Verify date and source authority
4. **Framing Analysis**: Examine text for manipulative adjectives, logical gaps, or missing context
5. **Synthesis**: Generate report in structured format

## Output Format

**Summary**: One-sentence verdict.

**Fact-Check**: List core claims with [STATUS] label and brief justification.

**Framing & Context**: Paragraph on tone, style, and missing information.

**Sources**: URLs used for verification.

### Example

**Input**: "Study proves: Chocolate helps weight loss."

**Summary**: Not scientifically valid; results extracted from context.

**Fact-Check**:

- "Chocolate aids weight loss" → **[NEEDS CONTEXT]**. Cited 2012 study was intentional hoax by Johannes Bohannon to expose poor science journalism.

**Framing Analysis**: Cherry-picking fallacy; single debunked study presented as general fact.
