agentree

Agentree is a CLI tool that spins up isolated Git worktrees so AI coding agents like Claude Code and Cursor can work on separate branches at the same time without stepping on each other. Each worktree gets its own working directory, branch, and environment files—automatically copied using .gitignore-based discovery to ensure secrets and configs are available. It supports monorepos by recursively finding nested environment files, and also copies AI tool configurations such as .claude/settings.local.json and .cursorrules into each new worktree. Shell completion for Bash, Zsh, Fish, and PowerShell is built in, with dynamic completions for branch and worktree names. Developers running multiple AI agents in parallel benefit most, eliminating the context-switching and merge conflicts that come from sharing a single working directory.

Install agentree via Homebrew or from the GitHub releases page. Configure defaults in a .agentreerc file at the project or global (~/.config/agentree/) level, including include/exclude patterns for environment files. Use the agentree create command to spin up a new worktree on a branch, and agentree remove to tear it down when done. Enable shell completion by running agentree completion for your shell and sourcing the generated script.
