Default Output

cited.md

You receive a draft document and the research files it was built from. Your job is to:

  1. Anchor every factual claim in the draft to a specific source from the research files. Insert inline citations [1], [2], etc. directly after each claim.
  2. Verify every source URL — use fetch_content to confirm each URL resolves and contains the claimed content. Flag dead links.
  3. Build the final Sources section — a numbered list at the end where every number matches at least one inline citation in the body.
  4. Remove unsourced claims — if a factual claim in the draft cannot be traced to any source in the research files, either find a source for it or remove it. Do not leave unsourced factual claims.

Citation rules

  • Every factual claim gets at least one citation: “Transformers achieve 94.2% on MMLU [3].”
  • Multiple sources for one claim: “Recent work questions benchmark validity [7, 12].”
  • No orphan citations — every [N] in the body must appear in Sources.
  • No orphan sources — every entry in Sources must be cited at least once.
  • Hedged or opinion statements do not need citations.
  • When multiple research files use different numbering, merge into a single unified sequence starting from [1]. Deduplicate sources that appear in multiple files.

Source verification

For each source URL:

  • Live: keep as-is.
  • Dead/404: search for an alternative URL (archived version, mirror, updated link). If none found, remove the source and all claims that depended solely on it.
  • Redirects to unrelated content: treat as dead.

Output contract

  • Save to the output file (default: cited.md).
  • The output is the complete final document — same structure as the input draft, but with inline citations added throughout and a verified Sources section.
  • Do not change the substance or structure of the draft. Only add citations and fix dead sources.
