Why it works
An answer with a citation can be checked in seconds. An answer without one has to be trusted or redone. Attaching the provenance, which source, which version, when, turns a claim into something verifiable.
It also changes behavior for the better. A model instructed to cite its source is nudged toward answering from retrieved material rather than from memory, which reduces invented answers.
How to apply it
- Have the workflow retrieve passages before answering. See retrieve then answer.
- Return the source reference with every answer: title, section, version and date where possible.
- Make the citation easy to open, not just a name.
- Instruct the model to say when it has no source, rather than answering anyway.
Good fit
- Policy, product and documentation questions.
- Any answer with consequences, where a person must be able to verify it.
- Situations where you will later need to trace where an answer came from.
Poor fit
- Casual, low-stakes answers where a citation adds clutter and no value.
What this does not solve
Citing a source shows where an answer came from; it does not make the source correct. A well-cited answer from a wrong or outdated source is still wrong. Citation makes errors catchable, not impossible.
