What I do is have a quick command that spins up a worktree on a repo with my ghostty splits as I like them and the tmux named the worktree. I then tell the Claude code about the tmux when it needs to look. It’s pretty good at natively handling the tmux interactions.

Ideally Ghostty would offer primitives to launch splits but c’est la vie. Apple automation it is.
