Fact-check the following claim: "$ARGUMENTS"
1. Decompose
Break the claim into specific, verifiable sub-claims. List them explicitly before searching.
2. Search for Evidence
For each sub-claim:
paper-search google web "<sub-claim as question>"
paper-search semanticscholar snippets "<sub-claim keywords>"
paper-search semanticscholar papers "<sub-claim keywords>" --limit 5
3. Verify Sources
For each promising source:
paper read <arxiv_id> <relevant section> # for academic papers
paper-search browse <url> # for web pages
Prefer primary sources (original papers, official data) over secondary reports.
4. Assess
For each sub-claim, assign a verdict:
- Supported: strong evidence from multiple reliable sources
- Partially supported: some evidence, with caveats
- Unsupported: no evidence found, or evidence contradicts the claim
- Uncertain: insufficient evidence to judge
5. Report
Present:
- The original claim
- Each sub-claim with its verdict and supporting evidence
- An overall assessment
- All sources cited with URLs
Guidelines
- Always cite specific sources — never state a verdict without evidence.
- Distinguish between "no evidence found" and "evidence contradicts."
- Note the quality and recency of sources.
- If a claim is about a specific paper, read that paper directly rather than relying on summaries.
