mkwt

Create a new git worktree and branch.

Usage

/mkwt <name> — Create a worktree with a new branch <name> from the repo's default branch (e.g. main, dev).

The <name> argument is required. If not provided, ask the user for a name.

Workflow

1. Validate the name argument is provided.

2. Detect the worktree base directory by inspecting existing worktrees:

   git worktree list
   

   • Look at paths of worktrees OTHER than the main worktree (the first entry, which is the repo itself).
   • If secondary worktrees exist, derive the base directory from their common parent. For example, if existing worktrees are at /Users/foo/worktrees/meadow/branch_a and /Users/foo/worktrees/meadow/branch_b, the base is /Users/foo/worktrees/meadow/.
   • If NO secondary worktrees exist (only the main repo), ask the user where to create the worktree.
