Requirements

Install arc

macOS (Homebrew)

brew install yash-srivastava19/arc/arc-prs

pipx

pipx install arc-prs

uv

uv tool install arc-prs

Verify your environment after installing:

arc setup

arc setup checks that git and gh are on PATH, that gh is authenticated, and that git rerere is enabled. It writes no configuration files — it only reads your environment.

---

Upgrade

arc upgrade

Upgrades arc using whichever package manager installed it. Pass --help to see the detected installer.

---

Shell completions

bash

Add to ~/.bashrc or ~/.bash_profile:

eval "$(arc completions bash)"

zsh

Add to ~/.zshrc:

eval "$(arc completions zsh)"

fish

Run once, or add to ~/.config/fish/config.fish:

arc completions fish | source

---

Uninstall

# Homebrew
brew uninstall arc-prs

# pipx
pipx uninstall arc-prs

# uv
uv tool uninstall arc-prs

arc does not write anything outside your project. The only per-repo artifact is .arc/state.json, which is git-ignored and safe to delete.
