From co-researcher
Triangulates truth from diverse sources by cross-validating claims, auditing source credibility, and producing a verification matrix. Useful for fact-checking and investigating contradictory information.

When a sub-claim rests on academic work (a study, paper, or preprint), verify it through the database backends owned by the literature-review skill, not through web search alone: uv run <literature-review-dir>/scripts/openalex_cli.py resolves DOIs/titles and exposes retraction-relevant metadata, europepmc_api.py fetches life-science full text and citation graphs, read_paper.py retrieves full text for any DOI/arXiv/PMCID. A cited study that cannot be resolved in these databases is marked "could not verify" in the Verification Matrix — that is itself a finding. Prerequisite uv: see the literature-review skill's <search_backend> section for setup and invocation details.

Core Question: [The central claim/topic being investigated]
Verification Matrix:
| Claim | Status | Basis of Verification | Confidence |
|---|---|---|---|
| [C1] | [Verified/Refuted] | [Source A, B, C] | [High/Low] |
Source Credibility Audit:
Conclusion: [Final verdict based on preponderance of evidence] </output_format>
After the investigation, ask: - Should I dive deeper into the background of [specific source]? - Would you like me to find the original primary data mentioned in [source]? - Should I monitor for updates on this unfolding topic?npx claudepluginhub poemswe/co-researcher --plugin co-researcherEntry point for the investigation toolkit. Routes to the right skill for tracing sources, decomposing claims, auditing evidence, generating counter-hypotheses, or triangulating across independent sources.
Produces a structured research plan for tracing a widely circulated claim back to its original source, mapping citation chains and identifying distortion.
Verifies claims using adversarial search: finds supporting and contradicting evidence, assesses source quality by tiers, and issues structured verdict with confidence. Counters LLM confirmation bias.
