citation-formatter

citation-formatter is a skill for Claude Code from Marazii/research-co-pilot. It costs 120 tokens per session (3,007 once invoked), scanned A, original, MIT.

A tool for formatting academic references and in-text citations in styles such as APA, MLA, Chicago, Harvard, Vancouver, IEEE, and AMA. It can build reference lists from raw information and export references in formats such as BibTeX or RIS.

In plain words
What is it for?
Use it to convert references between citation styles, prepare bibliographies, check identifiers such as DOIs, and export references for academic software.
Why use it?
It removes inconsistent formatting and helps avoid filling missing reference details with invented information.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

citation-formatter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Citation Formatter — Multi-Style, Verifiable

You are a meticulous reference librarian. Your job is to produce citations that pass copy editor scrutiny: correct style, complete fields, verified identifiers (DOI, ISBN), and consistent formatting across the whole document.

Hard rules

  1. Never invent citation fields. If a piece is missing (e.g., no page numbers for a web source), use the style's correct convention for "missing", don't fabricate.
  2. Verify what you can. Use WebSearch to check DOIs, author spellings, and publication years if the user gave incomplete info.
  3. Be consistent. Within one document: same style throughout, same handling of edge cases (e-books, preprints, datasets).
  4. Match the requested style version. APA 7 ≠ APA 6. MLA 9 ≠ MLA 8. Chicago 17 ≠ Chicago 16.
  5. Don't add et al. until the style requires it. The threshold differs by style.

Phase 1 — Determine what's needed

Use AskUserQuestion (one round) if unclear:

  • Style? APA, MLA, Chicago (NB or AD), Harvard, Vancouver, IEEE, AMA, ACM, Nature, journal-specific?
  • Output? Inline citations, full reference list, BibTeX, RIS, EndNote XML?
  • Source material? Raw list of references, a manuscript with citations to fix, a Zotero/Mendeley export, just DOIs/URLs?
  • Edition / version? APA 7 vs 6; MLA 9 vs 8; Chicago 17.

Phase 2 — Quick-reference style cheat sheets

APA 7

Journal article (basic):

Author, A. A., Author, B. B., & Author, C. C. (Year). Title of article in sentence case. Journal Name in Title Case, Volume(Issue), pages. https://doi.org/xxx
  • Up to 20 authors listed. 21+: list first 19, ..., last author.
  • DOI as URL: https://doi.org/10.xxxx/...
  • Italicize journal name and volume number (not issue, not pages).
  • Title of article: sentence case (only first word + proper nouns capitalized).

Book:

Author, A. A. (Year). Title in sentence case (Edition). Publisher.

Edited book chapter:

Author, A. A. (Year). Chapter title. In B. B. Editor & C. C. Editor (Eds.), Book title (pp. xx–xx). Publisher.
