A bundle is a named group of related tools. A tool has a name, a homepage, an install command (per OS), and a backend that tells lfg how to run it (brew, apt, mise, npm, curl, skills, or custom).

Built-in bundles

The default preset ships with bundles for a typical dev box:

• barebones — Homebrew, mise, node-lts, pnpm, bun, yarn, python, uv.
• terminal-essentials — interactive shell quality-of-life: zoxide, ripgrep, lazygit, tailscale, tmux, plus ghostty (macOS only, brew cask) and zsh (Linux only, since recent macOS already ships a current zsh).
• ai-harnesses — AI coding CLIs (Claude Code, Codex, OpenCode, Droid).
• skills — cross-harness AI skills installed via npx skills add. Gated until node-lts is selected.
• mcp — official Model Context Protocol servers for any MCP-aware harness.

You can replace this entirely with a custom preset — see Custom presets.

Tree picker behaviour

Marker	Meaning
[●]	mandatory — can't be unchecked
[✓]	selected
[ ]	not selected
→ v1.2.3	live latest version (looked up from upstream registry)
ALREADY INSTALLED	bucket for tools detected on PATH already

Live versions resolve asynchronously per tool with a 3 s timeout — the picker renders immediately with the parsed @version from the install command and updates in place once the registry responds.

Tool info card

Press i on any tool to open a card showing:

• description
• homepage / repo
• the exact install command for your OS
• any post_install steps that will run after the main install

Useful for sanity-checking what a bundle is about to do before you hit confirm.

Source backends

Source	What it does
brew	brew install <name> (macOS + linuxbrew on Linux)
apt	sudo apt-get install -y <name> (Linux)
mise	mise use -g <plugin>@<ver> for language runtimes
npm	npm i -g <pkg>
curl	arbitrary curl … | sh install scripts
skills	npx skills add <url> (requires node-lts)
custom	the install_mac / install_linux strings as-is

Bootstrap-able backends (brew, mise, node) are auto-installed at the start of a run when at least one selected tool needs them.
