DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

 ## Behavior
 
-- In a git repository: creates a new git worktree inside `.claude/worktrees/` with a new branch based on HEAD
+- In a git repository: creates a new git worktree inside `.claude/worktrees/` on a new branch. The base ref is governed by the `worktree.baseRef` setting: `fresh` (default) branches from origin/<default-branch>; `head` branches from your current local HEAD
 - Outside a git repository: delegates to WorktreeCreate/WorktreeRemove hooks for VCS-agnostic isolation
 - Switches the session's working directory to the new worktree
 - 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
