Drop Lily into Claude and get a Citation & Reference Manager who formats citations across APA, Harvard, MLA, Chicago, Vancouver, and OSCOLA, builds complete reference lists, converts between styles, fixes existing bibliography errors, and explains the rules clearly enough that you stop making the same mistakes twice. Referencing is genuinely complicated — different styles have different rules, the same source type formats differently in each system, and the standards change with each new edition. Lily is one of the most rule-aware AI citation tools available in Claude format — she always asks for the required style before generating anything (APA and Harvard look similar but have important differences), specifies which edition she is applying, and acknowledges institutional variation (Harvard has no single authoritative standard). She handles the tricky situations most citation generators get wrong: no author, no date, secondary citations, social media, legal cases, and organisational authors. What you get → Citation formatting across all major styles — APA 7th edition, Harvard, MLA 9th edition, Chicago 17th edition (author-date and notes-bibliography systems), Vancouver (ICMJE), and OSCOLA for UK legal citations, covering journal articles, books, book chapters, websites, government reports, theses, datasets, podcasts, social media, and legal cases → Complete reference lists and bibliographies — correctly structured, alphabetised, and formatted reference lists, distinction between reference list (cited works only) and bibliography (all consulted works) applied by style, error correction in existing reference lists, and full citation conversion from one style to another → In-text citation guidance — author-date vs footnote vs numbered system explained, multiple author rules (2, 3, 4+ authors) by style, secondary citations (citing a source cited in another source), DOI and URL handling, and when and how often to cite quotations vs paraphrases → Tricky source handling — no author, no date, organisational authors, online-only sources, social media posts, archival materials, oral sources, and government reports handled correctly with the specific rule explained rather than guessed at → Citation strategy guidance — citation density (how much is enough vs over-citation), seminal vs recent source balance, the difference between plagiarism, paraphrase, and quotation, self-plagiarism and citing your own previous work, and citing what you have not been able to access directly → Reference manager tool guidance — Zotero, Mendeley, and EndNote workflow advice, export format troubleshooting, common reference manager formatting errors fixed, and reference library organisation guidance for larger research projects 📄 lily-citation-manager.skill Under 2 min install Works with Claude, ChatGPT & any AI chat How to install Download the .skill package → open Claude → paste SKILL.md into your Project Instructions or system prompt → tell Lily the required style, the source details, and whether your institution has a specific guide → she formats correctly and explains the rule instantly.
