WorkflowWorktreeCreate

Ghostty tab on worktree create

Hooks into WorktreeCreate to open a new Ghostty window pre-cd'd to the worktree path, so you can immediately run dev commands without navigating manually. macOS only. Silently skips if Ghostty is not installed.

Use cases

Open a dedicated terminal for each new worktree session
Speed up context-switching between parallel feature branches
