git-worktree-runner

A command-line helper for creating and managing Git worktrees, which are separate working folders connected to one repository. It can also open an editor or AI coding tool in a selected worktree.

In plain words
What is it for?
It is for creating worktrees from branches or tags, opening development tools in them, running commands there, listing them, and removing them.
Why use it?
It avoids repeatedly switching one folder between branches and makes parallel feature work easier to organize.

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

git-worktree-runner 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.

Git Worktree Runner (gtr)

git-worktree-runner (gtr) is a CLI tool that wraps git worktree with quality-of-life features for modern development workflows including editor and AI tool integration.

Quick Start

# Create a new worktree
git gtr new feature-branch

# Create from a remote branch
git gtr new my-branch --from origin/feature-branch

# Open editor in the worktree
git gtr editor feature-branch

# Start AI tool (claude, codex, etc.) in the worktree
git gtr ai feature-branch

# Remove a worktree
git gtr rm feature-branch

Commands

Creating Worktrees

# Create a new worktree with a new branch
git gtr new feature-name

# Create from a specific ref (remote branch, tag, commit)
git gtr new my-branch --from origin/main
git gtr new hotfix --from v1.2.3

# Create and immediately open in editor
git gtr new feature -e

# Create and immediately start AI tool
git gtr new feature -a

# Create with both editor and AI tool
git gtr new feature -e -a

Opening Editor / AI Tool

# Open the configured editor for a worktree
git gtr editor feature-branch

# Start configured AI tool in a worktree
git gtr ai feature-branch

Running Commands

# Run an arbitrary command in a worktree
git gtr run feature-branch npm test
git gtr run feature-branch pnpm build

Navigation

# Navigate to a worktree directory
cd "$(git gtr go feature-branch)"

Listing and Managing

# List all worktrees
git gtr list

# Remove a worktree
git gtr rm feature-branch

# Rename a worktree
git gtr mv old-name new-name

Configuration

# Set default editor (cursor, vscode, zed, etc.)
git gtr config set gtr.editor.default cursor

# Set default AI tool (claude, codex, opencode, aider, etc.)
git gtr config set gtr.ai.default claude

# Configure files to copy into new worktrees
git gtr config add gtr.copy.include "**/.env"
git gtr config add gtr.copy.include "**/.env.local"
git gtr config add gtr.copy.include "**/.env.example"

# View current configuration
git gtr config list

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.
