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.

Claude Code v2.1.48

Tmux Integration for Worktrees

What

Automatically create tmux sessions when starting worktrees, with iTerm2 native pane support.

Usage
claude --worktree --tmux
claude -w --tmux=classic  # Use traditional tmux instead of iTerm2 integration
Details
  • Creates a tmux session for parallel worktree work
  • Uses iTerm2 native panes when available for better integration
  • Use --tmux=classic for traditional tmux behavior
  • Session management options on exit: keep both, keep worktree only, or remove all
Evidence

New --tmux flag (search for "Create a tmux session for the worktree")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
