What
Claude can run a team of agents, helpers that work alongside it. Each member can have a worktree, a separate working copy of the repository. Cleaning up a team now deletes only the team's own folder. It no longer goes through the members and removes each one's worktree.
Why
Team members' worktrees may be left on disk after cleanup, so check for them if you rely on cleanup to tidy up.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
Worktree removal may have moved elsewhere rather than stopped.
