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.
