Sounds like a lot of work just for it to maybe not work anyways

Absolutely. Quite a bit of work one time by one person willing to document the steps or even better create automation scripts for Ansible, Docker, Podman, Systemd, etc... and then automation for everyone using agents. As to success I would suggest it may be better than zero visibility or trusting what the agent says it did. Due diligence and a repeatable standard as apposed to running with scissors.

This is probably most important for anyone operating agents on corporate systems. I would suggest corporate security should take interest in this idea so they have a good answer for auditors, insurance companies, investors and customers. A full audit trail of what every agent had access to and ingested.
