Worktree Parallel Init

Create multiple git worktrees for parallel development: $ARGUMENTS

Instructions

You are setting up parallel worktrees so the user can work on multiple tasks simultaneously in separate Ghostty terminal panels, each running its own Claude instance.

Step 1: Validate Environment

1. Check this is a git repository: git rev-parse --is-inside-work-tree
2. Get the repo name: basename $(git rev-parse --show-toplevel)
3. Get the main branch name (check for main or master): git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@' — if that fails, default to main
4. Ensure working tree is clean: git status --porcelain. If dirty, warn the user and ask if they want to continue.
5. Fetch latest: git fetch origin

Step 2: Parse Tasks

Parse tasks from $ARGUMENTS. Tasks are separated by | (pipe character).

If $ARGUMENTS is empty, use AskUserQuestion to ask the user to describe their tasks (they can provide multiple separated by |).

For each task description:

• Trim whitespace
• Generate a kebab-case branch name: wt/<kebab-case-task> (max 50 chars, alphanumeric and hyphens only)
• Generate a worktree directory path: ../worktrees/<repo-name>/wt-<kebab-case-task>

Step 3: Create Worktrees

For each task:

1. Create the parent directory if needed: mkdir -p ../worktrees/<repo-name>
2. Create the worktree:

   git worktree add -b wt/<name> ../worktrees/<repo-name>/wt-<name> origin/<main-branch>
   

3. Write a .worktree-task.md file inside the new worktree with this content:

   # Worktree Task
   
   **Branch:** wt/<name>
   **Task:** <original task description>
   **Created:** <ISO date>
   **Source repo:** <path to main repo>
   

Step 4: Check for Dependencies

If a package.json exists in the repo root, note that each worktree may need npm install (or the appropriate package manager).

Check for:

• package-lock.json → npm install
• yarn.lock → yarn install
• pnpm-lock.yaml → pnpm install
• bun.lockb → bun install

Step 5: Output Summary

Display a clear summary table:

| # | Task | Branch | Path |
|---|------|--------|------|
| 1 | ... | wt/... | ../worktrees/repo/wt-... |

Then display ready-to-copy commands for Ghostty panels. For each worktree:

# Panel <N>: <task description>
cd <absolute-path-to-worktree> && claude

If dependencies were detected, add a note:

# Note: Run <package-manager> install in each worktree before starting

Finally, remind the user:

• Open a new Ghostty panel with Cmd+D (split right) or Cmd+Shift+D (split down)
• When done with a task, use /worktree-deliver to commit, push, and create a PR
• After merging all PRs, use /worktree-cleanup --all from the main repo
