What is a citation in an AI answer?

A citation in an AI answer is a reference, attached to a specific claim, that points to its source, such as a policy clause or a record. It lets a reader check the claim against its origin. A citation shows where an answer came from; it does not, on its own, show that the answer is right.

Why do citations matter for people who review AI agents?

An answer without citations asks you to trust it. An answer with citations gives you a way to check it, quickly, on the claims that matter. In review work that changes the job: rather than researching every reply from scratch, you check that each important claim is supported by the source it names.

It also gives you a clear reason when you reject a draft. "The cited clause covers water damage from burst pipes, not from flooding" is a precise, defensible note that helps the people who improve the agent.

How do citations work in practice?

A well-built agent answers only from approved sources and attaches a reference to each factual claim. On a governed platform, every fact reaching the agent also carries its provenance: whether it came from the system of record itself, from a named party who answers for it, from a customer's own statement, or from outside, such as an emailed document. That tells you how much weight the cited source can bear.

When you review a cited answer, do three checks:

1. Does the source exist and is it current? A citation to a superseded policy is a problem.
2. Does the source say what the answer claims? Open it and read the passage.
3. Is the source strong enough for this action? A customer's own statement can support a reply; it should not, on its own, support a payment.

What is an example?

An agent drafts a reply to a customer asking whether their travel insurance covers a cancelled flight. The draft says yes, up to 500, and cites section 4.2 of the policy wording. A reviewer we will call Arjun opens section 4.2. It covers cancellation by the traveller for illness. The customer's flight was cancelled by the airline, which section 4.4 covers on different terms. The citation was real; the claim did not follow from it. Arjun amends the draft to cite 4.4 and corrects the amount.

How is a citation different from a grounded answer?

A grounded answer is one built from approved sources rather than from the model's general knowledge, explained in what a grounded answer is. A citation is the visible pointer that lets you check the grounding. An answer can be grounded with poor citations, which makes it hard to check; or carry citations and still misread its sources, as in Arjun's case.

The same discipline applies to you in interviews. A strong answer to a behavioural question is "cited" with a specific situation, action and result, which is the shape of a STAR answer.

Which terms are related?

• Source checking: verifying a claim against its origin.
• Provenance: the record of where a fact came from and how far it can be trusted.
• Hallucination: a confident claim with no basis in any source.

Citations matter in privacy work too, where a reply must rest on the actual request and the law, as discussed in CCPA and the people who answer privacy requests with AI agents. For the wider skill set, read AI skills for job seekers.
