git-worktree

git-worktree is a skill for Claude Code, Codex from julianobarbosa/claude-code-skills. It costs 60 tokens per session (3,047 once invoked), scanned C, original, MIT.

A Git worktree manager for creating multiple working folders from one repository. A Git worktree lets you work on separate branches at the same time without repeatedly switching branches or hiding changes.

In plain words
What is it for?
Use it to create and remove worktrees, connect them to tmux windows, and manage several feature branches or coding-agent sessions at once.
Why use it?
It keeps parallel tasks isolated and makes it easier to run separate development sessions for each branch.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: positional $N argument; mentions Claude Code.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is git worktree add ../feature-x -b feature-x.

Good fit Use it to create and remove worktrees, connect them to tmux windows, and manage several feature branches or coding-agent sessions at once.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 C, and why

git-worktree scanned grade C with 1 finding 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (references/functions.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- **Locking a worktree doesn't prevent fs operations** — `git worktree lock` only blocks `git worktree remove`; `rm -rf` still works.

Git Worktree Skill

Manage parallel development environments using git worktrees with seamless terminal integration.

Overview

Git worktrees enable multiple working directories from a single repository:

  • Isolated feature development without branch switching
  • Run multiple Claude Code instances in parallel
  • Context switching without stashing uncommitted changes
  • Clean separation of experimental work

Quick Commands

wt - Worktree Manager

The wt command creates worktrees with automatic terminal integration:

# Create worktree with tmux window
wt add-new-feature

# This will:
# 1. Create git worktree named 'add-new-feature'
# 2. Create new tmux window in current session
# 3. Rename window to 'add-new-feature'
# 4. Change directory to the worktree

tmux Integration

Workflow: Create Worktree + tmux Window

# Function for ~/.zshrc or ~/.bashrc
wt() {
    local name="$1"
    local base_branch="${2:-main}"
    local repo_root=$(git rev-parse --show-toplevel 2>/dev/null)
    local worktree_path="$repo_root/.worktrees/$name"

    # Validate we're in a git repo
    if [[ -z "$repo_root" ]]; then
        echo "Error: Not in a git repository"
        return 1
    fi

    # Create worktree directory
    mkdir -p "$repo_root/.worktrees"

    # Create worktree with new branch
    if git worktree add -b "$name" "$worktree_path" "$base_branch" 2>/dev/null; then
        echo "Created worktree: $worktree_path"
    elif git worktree add "$worktree_path" "$name" 2>/dev/null; then
        echo "Attached to existing branch: $name"
    else
        echo "Error: Failed to create worktree"
        return 1
    fi

    # tmux integration
    if [[ -n "$TMUX" ]]; then
        # Create new window with worktree name
        tmux new-window -n "$name" -c "$worktree_path"
        echo "Created tmux window: $name"
    else
        # Not in tmux, just cd
        cd "$worktree_path"
        echo "Changed to: $worktree_path"
    fi
}

# Remove worktree and tmux window
wt-rm() {
    local name="$1"
    local repo_root=$(git rev-parse --show-toplevel 2>/dev/null)
    local worktree_path="$repo_root/.worktrees/$name"

    # Remove git worktree
    git worktree remove "$worktree_path" --force 2>/dev/null

    # Close tmux window if exists
    if [[ -n "$TMUX" ]]; then
        tmux kill-window -t "$name" 2>/dev/null
    fi

    # Optionally delete branch
    git branch -d "$name" 2>/dev/null

    echo "Removed worktree: $name"
}

# List all worktrees
wt-ls() {
    git worktree list
}

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it

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.
