Cursor user says agents kept putting work in a macOS temporary folder that the system then wiped, losing about 16 hours of work (first-person)
A post on the Cursor community forum on 24 October 2026 by a self-described heavy Cursor user on macOS says that over the previous week Cursor agents repeatedly created isolated git worktrees in the system temporary folder /tmp, bound the chat workspace to that path, and kept working there. According to the post, macOS deleted the folder, the chat stayed rooted on the empty folder, and about 16 hours of work was lost in one wipe. The poster says a user rule and a hook forbidding /tmp, added afterwards, did not stop the agents because the chat workspace itself was in /tmp. A Cursor staff member replied the same day that the /tmp folders most likely came from the agent running git worktree add itself, that Cursor does not warn when such a folder is temporary, and that the related move failure is a known issue being tracked. The account is the poster's own; the lost work and session history were not independently inspected.
