Tool changes

2026-10-18check_referenceadded
Whether a reference resolves to a real work. Use when an answer is about to cite a paper. Give a DOI, an arXiv id or the reference as written. Answers found, confirm (with the reason), not found in the named sources on a date, or couldn't check. A not-found is not proof a work was never published.
2026-10-03retraction_listingadded
Whether the Retraction Watch database lists the given DOI as retracted, from the dated export CiteStamp joins weekly. Use when a user asks whether a paper has been retracted or carries a retraction notice. Not listed means not in that export; the publisher record is not checked.

Tools (7)

`check_reference`read-only	Whether a reference resolves to a real work. Use when an answer is about to cite a paper. Give a DOI, an arXiv id or the reference as written. Answers found, confirm (with the reason), not found in the named sources on a date, or couldn't check. A not-found is not proof a work was never published.
`edges_about`read-only	Every edge touching the given work in either direction, each tagged asserted\|inferred with attribution and provenance. Use when a user asks 'what is known about this paper's citations' or wants the whole neighbourhood in one call. Paged.
`references_of`read-only	What the given work CITES (its reference list). Use when a user asks what a paper relies on, whether a specific citation in it exists, or wants to check a reference before reusing it. Paged.
`retraction_listing`read-only	Whether the Retraction Watch database lists the given DOI as retracted, from the dated export CiteStamp joins weekly. Use when a user asks whether a paper has been retracted or carries a retraction notice. Not listed means not in that export; the publisher record is not checked.
`what_cites`read-only	Works that CITE the given DOI (incoming citations). Use when a user asks who cites a paper, how much a work has been cited, or whether a claimed 'cited by' is real. Returns edges with tier + attribution; paged.
`what_refutes`read-only	Edges recorded as REFUTING the given work or claim: human-signed refutations plus failed replication outcomes coded by the FORRT Replication Database. Use when a user asks whether a finding failed to replicate or has been contradicted.
`what_supports`read-only	Edges recorded as SUPPORTING the given work or claim: human-signed support claims plus successful replication outcomes coded by the FORRT Replication Database. Use when a user asks whether a finding held up or was replicated.
