Launch a new tmux session from the right directory — without polluting the current one
Tools like team and adhoc (from the mux-relay framework) derive the project root from $PWD at invocation time. The natural instinct is to open a new tmux window, cd to the target directory, then run the command. That works, but it leaves a ghost window in the original session — and if that window gets cleaned up or the session reshuffles, pane working directories can silently drift to deleted paths.
A subshell avoids all of that:
(j my-project && team)
The parentheses spawn a subshell. Inside it, j (zoxide) changes directory to the project, then team launches the new session with the correct $PWD. Because new-session -d is detached and switch-client handles the jump, the new session is fully independent — no nesting, no leftover windows.
When the subshell exits (right after team returns), the original pane's $PWD is untouched. You never left it.
This pattern works for any command that reads $PWD but doesn't accept a -C / --directory flag:
(cd ~/Projects/something && explore)
(cd $(z resolve another-project) && adhoc claude)
One pane, one command, zero side effects.
