Git worktree checkouts now run in parallel using git's checkout.workers, capped at 16
What
When Claude Code checks out a git worktree (a separate working copy of a repository), it now speeds this up by using git's checkout.workers setting, which lets git parallelize the checkout across multiple workers. If the repository doesn't already have checkout.workers configured, Claude Code sets it for the operation itself, choosing a value between 1 and 16. This applies both when quickly resuming an existing worktree and when creating a new one.
Why
Parallelizing the checkout can make worktree setup noticeably faster, especially for larger repositories, without requiring any configuration from you.
