Cursor Moves Subagents Onto Separate VMs With Independent Project Copies
The 2026-08-19 Cursor release runs subagents on their own virtual machines, each with an independent copy of the project, so concurrent test runs and parallel bug fixes no longer collide over the same working tree. This is the hosted equivalent of handing every agent its own git worktree, a pattern practitioners have been assembling by hand with tmux and worktree scripts. The tradeoff is per-agent setup cost, which is why worktree isolation is worth reserving for agents that actually mutate files.
