How to Prevent a Knowledge Assistant From Using Outdated Documents

A knowledge assistant may return a retired procedure even when a newer document exists. The old file may remain indexed, duplicate copies may have similar titles, or metadata may not distinguish current from archived material. Prompt wording alone cannot fix a retrieval source that contains conflicting versions.

Make source ownership clear

Assign an owner and status to each knowledge source. Record version, effective date, review date, and any audience restriction. Define how updated documents replace old versions and how deletions propagate through indexes, caches, and derived embeddings.

• Exclude archives from retrieval unless users explicitly request historical material.
• Include source name and date with retrieved passages.
• Test queries likely to expose conflicts between old and current policies.
• Monitor indexing failures and the age of the last successful refresh.
• Give users a way to report stale or incorrect references.
