Fact-check the following claim: "$ARGUMENTS"
- Decompose
Break the claim into specific, verifiable sub-claims. List them explicitly before searching.
- 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
- 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.
- 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
- 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.
