Git Worktree Manager

Manage git worktrees for running parallel Claude Code sessions.

Commands

/worktree create <branch-name> [from <base-branch>]

Creates a new git worktree for parallel development.

Examples:

• /worktree create fix-bug - Creates worktree from origin/main
• /worktree create fix-bug from main - Creates worktree from main branch
• /worktree create feature-x from develop - Creates from develop

/worktree list

Lists all active worktrees.

/worktree remove [<worktree-name>]

Removes a worktree and its local branch.

Instructions

For create command:

1. Parse arguments:

   • <branch-name>: Required, the new branch name
   • <base-branch>: Optional, defaults to origin/main

2. Determine paths:

   REPO_BASENAME=$(basename "$PWD")
   WORKTREE_PATH="../${REPO_BASENAME}--${BRANCH_NAME}"
   ABSOLUTE_PATH=$(cd .. && pwd)/${REPO_BASENAME}--${BRANCH_NAME}
   

3. Fetch latest:

   git fetch origin
   

4. Create worktree:

   git worktree add -b <branch-name> <worktree-path> <base-branch>
   

5. Install dependencies:

   cd <worktree-path> && npm install
   

6. Return to original directory

7. Check if running inside tmux:

   if [ -n "$TMUX" ]; then
     # Inside tmux - open new window with claude
     tmux new-window -c "<absolute-path>" -n "<branch-name>" "claude; bash"
   fi
   

8. CRITICAL - Output this format at the end:

   If tmux was used:

   Worktree created successfully!
   
     Branch: <branch-name>
     Base:   <base-branch>
     Path:   <absolute-path>
   
   New tmux window "<branch-name>" opened with Claude Code.
   Switch to it with: Ctrl+b n (next) or Ctrl+b w (window list)
   

   If NOT in tmux (fallback):

   Worktree created successfully!
   
     Branch: <branch-name>
     Base:   <base-branch>
     Path:   <absolute-path>
   
   To start a parallel Claude Code session, copy and run:
   ┌────────────────────────────────────────────────────────────┐
   │ cd <absolute-path> && claude                               │
   └────────────────────────────────────────────────────────────┘
   

For list command:

Run and display output:

git worktree list

For remove command:

1. If no worktree name provided, show git worktree list and ask user to specify

2. Parse worktree name to extract branch:

   • Worktree format: <repo>--<branch>
   • Extract branch: everything after --

3. Ask for confirmation before proceeding

4. Remove worktree:

   git worktree remove <worktree-path> --force
   

5. Delete local branch:

   git branch -D <branch-name>
   

6. Confirm: "Removed worktree and local branch. Remote branch preserved for PR."

Safety Rules

• Always git fetch before creating to have latest refs
• Never remove worktrees with uncommitted changes without explicit confirmation
• Never remove the main worktree (one without -- in directory name)
• Preserve remote branches when removing (only delete local branch)
• If branch already exists, ask user if they want to use existing or create new name
