Exit a worktree session created by EnterWorktree and return the session to the original working directory. ## Scope This tool ONLY operates on worktrees created by EnterWorktree in this session. It will NOT touch: - Worktrees you created manually with `git worktree add` - Worktrees from a previous session (even if created by EnterWorktree then) - The directory you're in if EnterWorktree was never called If called outside an EnterWorktree session, the tool is a **no-op**: it reports that no worktree session is active and takes no action. Filesystem state is unchanged. ## When to Use - The user explicitly asks to "exit the worktree", "leave the worktree", "go back", or otherwise end the worktree session - Do NOT call this proactively — only when the user asks ## Parameters - `action` (required): `"keep"` or `"remove"` - `"keep"` — leave the worktree directory and branch intact on disk. Use this if the user wants to come back to the work later, or if there are changes to preserve. - `"remove"` — delete the worktree directory and its branch. Use this for a clean exit when the work is done or abandoned. - `discard_changes` (optional, default false): only meaningful with `action: "remove"`. If the worktree has uncommitted files or commits not on the original branch, the tool will REFUSE to remove it unless this is set to `true`. If the tool returns an error listing changes, confirm with the user before re-invoking with `discard_changes: true`. ## Behavior - Restores the session's working directory to where it was before EnterWorktree - Clears CWD-dependent caches (system prompt sections, memory files, plans directory) so the session state reflects the original directory - If a tmux session was attached to the worktree: killed on `remove`, left running on `keep` (its name is returned so the user can reattach) - Once exited, EnterWorktree can be called again to create a fresh worktree
