[Issue] Agent still references deleted knowledge base file

[kristianakola]

Issue Description
After deleting an outdated file from the knowledge base, the agent continues to indicate that it has access to that file.

The deleted file was org-bestpractices.md.

Would it be possible to provide an option to download the uploaded file as well, for version checks?

Actual Behavior
The agent still lists the deleted file as a source.
