An AI agent memory audit inventories memory records and examines why each was written, which source supports it, whether it was ever read, and whether its assumptions still match the current system. It separates temporary plans and completed fixes from durable knowledge that remains useful.
Audits should be non-destructive by default. Suspect entries can be flagged, quarantined, superseded, or queued for review while prior history remains recoverable, and deletion should require evidence that the target is safe to remove under an explicitly authorized policy.

An agent memory audit is a review of the information an AI agent has stored for later use. It checks where each memory came from, whether it is still true and useful, whether it is duplicated, and whether it belongs in that agent's scope.
For example, an audit might find an old note saying that a project uses a library version that has since changed. The note can be flagged or replaced by a newer verified record while the old history remains recoverable instead of being deleted without evidence.
