What it is
multi-source-paper-search is a literature-search skill for Claude Code. It fans out one request to OpenAlex, Semantic Scholar, arXiv through Valyu, and Perplexity, then deduplicates papers and writes a cited synthesis.
Why it is useful
Single-source paper search is biased and incomplete. This skill separates exact mechanical work, such as fan-out and DOI or title deduplication, from semantic synthesis and claim reconciliation.
Best uses
- Scan a research topic across multiple academic sources.
- Identify consensus, disagreement, and source-specific findings.
- Produce a cited literature overview with skipped-source transparency.
Notes
OpenAlex works without keys, while other sources may need API keys. The README explicitly documents graceful degradation, so reports should state which sources actually ran.
