Running several Claude sessions at once with git worktrees

Most people who try to run two Claude sessions at once do it in the same folder, and then quietly stop because the results get weird.

They are not wrong about the weirdness. Two agents editing one working directory will overwrite each other's half-finished files, fight over one checked-out branch, and produce a repo that is half feature A, half feature B, and passes nothing.

The fix has been sitting in git since 2015 and almost nobody uses it.

git worktree add gives you a second folder,
same repository, same history, same one .git,
different branch checked out in each,
no shared index, no shared stash,
one terminal tab and one Claude per folder 🔥

I wrote the whole playbook. Real commands for create, list, remove and prune, the honest list of what does not parallelise, and the merge tax you are signing up for.
