Fact Checking

Fact Checking Workflow

OBJECTIVE: Cross-verify factual claims using INDEPENDENT data sources (not the same APIs the research used).

Step 1: Extract Claims

Identify specific factual assertions in the thesis:

• Price targets and levels mentioned
• Earnings figures, revenue numbers, growth rates
• News events, announcements, dates
• Comparative statements ("better than competitors")

Step 2: Verify Each Claim

For each claim, use your independent tools:

• Use fetch_yfinance_news for financial stats (PE ratio, EPS, revenue growth) and recent news
• Use search_web_exa for news events, announcements, lawsuits, regulatory actions

CRITICAL: These tools pull from DIFFERENT data sources than the research. If research says "EPS grew 22.9%" but Yahoo Finance shows different numbers, that's a discrepancy worth flagging.

Step 3: Classification

For each claim, classify as:

• VERIFIED: Independent source confirms the claim
• PARTIALLY VERIFIED: Generally correct but details differ
• UNVERIFIED: Cannot find supporting evidence from independent sources
• CONTRADICTED: Independent sources show different data
• OUTDATED: Was true but situation has changed

Step 4: Compile Report

List claims with verification status and source references.

Output Format

FACT CHECK REPORT: [SYMBOL] Thesis

VERIFIED CLAIMS:

QUESTIONABLE CLAIMS: ? [Claim] - Issue: [what's wrong] - Source: [reference]

CONTRADICTED CLAIMS: x [Claim] - Reality: [what independent sources show] - Source: [reference]

ACCURACY SCORE: {verified}/{total} claims verified
