300300The EnterWorktree tool creates an isolated [git worktree](https://code.claude.com/docs/en/worktrees.md) and switches into it. Given a `path`, it switches into an existing worktree instead of creating a new one.

302* **Which worktrees `path` can name**: on first entry the target may be a worktree of the current repository. In a repository that holds other repositories, it may also be a worktree of a repository nested inside it. Before v2.1.203, a nested repository's worktree was rejected.
302* **Which worktrees `path` can name**: on first entry the target may be a worktree of the current repository. In a repository that holds other repositories, it may also be a worktree of a repository nested inside it.
303303* **When you're prompted**: a `path` outside `.claude/worktrees/` prompts for your approval before entering, since it moves the session's working directory and write access to that location. New-worktree creation and paths under `.claude/worktrees/` don't prompt. Before v2.1.206, Claude entered paths outside `.claude/worktrees/` without a prompt.
304304* **From inside a worktree**: from within a worktree session, only the `path` form is available and the target must be under `.claude/worktrees/` of the session's repository. The same holds for a subagent with a pinned working directory, such as [`isolation: worktree`](https://code.claude.com/docs/en/sub-agents#supported-frontmatter-fields).
305305* **When the tool is missing**: once [`permissions.blockWritesOutsideWorkingDirectories`](https://code.claude.com/docs/en/settings-reference#permissions-blockwritesoutsideworkingdirectories) is on, Claude Code removes `EnterWorktree` and `ExitWorktree` or refuses calls to them. To keep working in worktrees, see [Claude has no `EnterWorktree` tool](https://code.claude.com/docs/en/worktrees#claude-has-no-enterworktree-tool).
