1Use this tool ONLY when explicitly instructed to work in a worktree — either by the user directly, or by project instructions (CLAUDE.md / memory). This tool creates an isolated git worktree and switches the current session into it.
3## When to Use
5- The user explicitly says "worktree" (e.g., "start a worktree", "work in a worktree", "create a worktree", "use a worktree")
6- CLAUDE.md or memory instructions direct you to work in a worktree for the current task
8## When NOT to Use
10- The user asks to create a branch, switch branches, or work on a different branch — use git commands instead
11- The user asks to fix a bug or work on a feature — use normal git workflow unless worktrees are explicitly requested by the user or project instructions
12- Never use this tool unless "worktree" is explicitly mentioned by the user or in CLAUDE.md / memory instructions
14## Requirements
16- Must be in a git repository, OR have WorktreeCreate/WorktreeRemove hooks configured in settings.json
17- Must not already be in a worktree
19## Behavior
21- In a git repository: creates a new git worktree inside `.claude/worktrees/` with a new branch based on HEAD
22- Outside a git repository: delegates to WorktreeCreate/WorktreeRemove hooks for VCS-agnostic isolation
23- Switches the session's working directory to the new worktree
24- Use ExitWorktree to leave the worktree mid-session (keep or remove). On session exit, if still in the worktree, the user will be prompted to keep or remove it
26## Entering an existing worktree
28Pass `path` instead of `name` to switch the session into a worktree that already exists (e.g., one you just created with `git worktree add`). The path must appear in `git worktree list` for the current repository — paths that are not registered worktrees of this repo are rejected. ExitWorktree will not remove a worktree entered this way; use `action: "keep"` to return to the original directory.
30## Parameters
32- `name` (optional): A name for a new worktree. If neither `name` nor `path` is provided, a random name is generated.
33- `path` (optional): Path to an existing worktree of the current repository to enter instead of creating one. Mutually exclusive with `name`.
