Tools
| Tool | Description | Behaviour |
|---|---|---|
| check_retractions | Check DOIs for retractions, expressions of concern and corrections, using Crossref (which includes Retraction Watch data). Status per DOI: retracted, concern, corrected, other_notice, no_notice (nothing on record), not_in_crossref, invalid_doi, rate_limited or lookup_failed (could not be checked; say so, do not report it as clean). Use it before citing a paper whose status you are unsure of, or to screen a whole reference list. verify_references already includes this check. | Read-only |
| format_citations | Format references in a citation style (APA 7, MLA 9, Chicago author-date, Harvard, Vancouver, IEEE, AMA) or export them as BibTeX, RIS or CSL-JSON. By default every reference is first verified against Crossref, PubMed and OpenAlex, and verified references are formatted from the database record, so wrong years, pages or author names in the input are corrected. References that could not be verified are formatted exactly as written and flagged in `entries[].warnings`; tell the user about them. Returns the bibliography and, for text and html output, the matching in-text citation for each reference. | Read-only |
| prisma_flow_diagram | Draw a PRISMA 2020 flow diagram for a new systematic review from the record counts, as a PNG image plus an SVG and download links. Give the counts you have; boxes that follow arithmetically from others are filled in and marked as derived. The tool checks that the numbers add up (records identified minus removed equals screened, and so on) and returns a warning naming each box that does not, with the value it should have. Show those warnings to the user; the diagram always shows the numbers exactly as given. Add `otherMethods` counts to draw the second column (websites, organisations, citation searching). | Read-only |
| search_papers | Search PubMed and OpenAlex for real papers. Every result carries a DOI or PubMed ID that resolves, so nothing returned can be fabricated. Use it to find sources for a claim or a topic instead of recalling references from memory. Filters: publication year range, open-access only, study types, and the number of results. Retracted papers are left out by default. Preprints are included and marked `preprint: true`; tell the user a preprint is not peer reviewed. Results are ranked by the databases' relevance, alternating between the two sources. | Read-only |
| verify_references | Check every reference in a list against Crossref, PubMed and OpenAlex and report, for each one, whether the paper really exists and whether the details are right. Call this before presenting any reference list to the user, including references you wrote yourself. Input: a pasted reference list in any common style (APA, Vancouver, numbered, mixed), BibTeX, RIS, CSL-JSON, or one DOI per line. Each reference gets exactly one status: verified, verified_with_corrections (real paper, some details wrong; corrected metadata included), likely_fabricated (no such paper exists), not_found (could not be confirmed either way), retracted, or ambiguous (several papers fit). Never present a likely_fabricated, not_found or ambiguous reference as real, and always tell the user about a retracted one. At most 50 references per call. | Read-only |
