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.

Enhanced Backend Registry for Pane Management

The backend registry now intelligently selects the appropriate pane backend:

  • Detects iTerm2 and checks for it2 CLI availability
  • Prefers iTerm2 native split panes when available
  • Falls back to tmux with informative messaging
  • Supports user preference for tmux over iTerm2
Evidence

[BackendRegistry] Selected: iterm2 (native iTerm2 with it2 CLI), [BackendRegistry] Selected: tmux (fallback in iTerm2, it2 setup recommended)

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