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.
