# Grounded Citations Every claim taken from an outside source gets an inline numbered citation and a `Sources:` list, Perplexity-style. A ledger script owns the `url → [n]` mapping so the numbers and URLs come from retrieval, never from memory — the model only ever emits small integers it was handed. For high-stakes work the same ledger doubles as a fact-checking chain: verbatim quotes are attached to each source (rejected unless they literally appear in the fetched page text), claims from model knowledge are flagged `[unverified]`, and `verify --evidence` fails any draft whose cited sources carry no evidence. This skill covers answers in chat, written documents (markdown, PDF, docx, slides), and research reports. It does not cover academic BibTeX pipelines — for conference papers use the `research-paper-writing` skill, which this skill feeds (see `references/citation-formats.md`). ## When to Use Use whenever an answer or artifact rests on information you fetched rather than knew: - Research, comparisons, news summaries, "what is the current state of X" - Any deliverable you write to disk that quotes, paraphrases, or reports outside facts — reports, briefs, docs, decks, wiki pages - Fact-finding where the user will want to check your work - Multi-source synthesis where conflicting sources must be attributed Skip inline citations when the retrieval is incidental to another task — a quick syntax/version lookup mid-coding, casual conversation, creative writing.
