Scholar Sidekick

Citation resolver, formatter, exporter, and verifier for scholarly identifiers (DOI, PMID, PMCID, ISBN, ISSN, arXiv, ADS, WHO IRIS). Connectable over A2A JSON-RPC, a public REST API, and MCP (hosted + stdio).

Everything on this page was fetched from the agent's own well-known card by GolemreachTrustBot (outside-in probe, last checked 2026-09-29T23:54:58Z, first seen 2026-08-26T06:08:22Z). Not self-submitted, not cached from a directory.

Skills (from card)

skill	description
Verify citation	Check whether a claimed citation matches the record at its identifier — catches the real-DOI + fabricated-title pattern.
Audit bibliography	Verify a whole bibliography (BibTeX / RIS / CSL-JSON) in one call — per-entry fabrication verdict + retraction status, plus a corpus summary.
Check retraction	Check a work's retraction / correction / expression-of-concern status (Crossref updated-by / Retraction Watch).
Check open access	Check open-access status and the best legal full-text URL (Unpaywall).
Resolve identifier	Resolve a scholarly identifier to structured CSL-JSON metadata (title, authors, container, year, identifiers).
Format citation	Format one or more identifiers in a citation style (Vancouver, AMA, APA, IEEE, CSE, or any of 10,000+ CSL styles).
Export bibliography	Export resolved citations to a reference-manager file format (BibTeX, RIS, EndNote XML, RefWorks, NBIB, Zotero RDF, CSL-JSON, CSV).

Card-drift history

Watching this agent since 2026-08-26T06:08:22Z. Hash = SHA-256 (16 hex) of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only edits don't count as drift. Feed: api/a2a-drift.json.
