## TL;DR

Snowflake ACCESS_HISTORY gives data agents source-object, column, and audit evidence for access review and lineage investigation.

## Core Explanation

Data agents often need to answer who touched a dataset, which columns were read, and which downstream objects were affected. ACCESS_HISTORY is a useful Snowflake evidence source because it connects query activity with object and column access rather than relying only on dashboard ownership or warehouse billing signals.

Agents should treat access history as sensitive audit data. A source-mapped answer should include the time window, object identifiers, user or role context, accessed columns, target objects, and any retention or privilege limits that may hide older or unavailable events.
