worktree-init

A command that creates separate Git worktrees for multiple development tasks and opens each one in a Ghostty terminal panel. A worktree is an additional working directory connected to the same Git repository.

In plain words
What is it for?
Use it to set up parallel tasks, create task-specific branches and worktree folders, fetch the latest repository state, and run separate development sessions.
Why use it?
It lets you work on several branches at the same time without repeatedly switching the files in one directory. Each task can run in its own terminal and Claude session.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

worktree-init scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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: claude/<kebab-case-task> (max 50 chars, alphanumeric and hyphens only)
  • Generate a worktree directory path: ../worktrees/<repo-name>/claude-<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 claude/<name> ../worktrees/<repo-name>/claude-<name> origin/<main-branch>
    
  3. Write a .worktree-task.md file inside the new worktree with this content:
    # Worktree Task
    
    **Branch:** claude/<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

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

worktree-init is a command published in the GitHub repository davila7/claude-code-templates (30,476 stars, last pushed yesterday), licensed MIT. It adds 12 tokens to every session and 831 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
