Install CodeJackRabbit

One npm command installs the CLI on Windows, Linux and macOS. No executable download, no double-click installer and no manual PATH editing.

Requirements

• Node.js 20 or newer, which includes npm.
• Git, for repository reviews.
• A terminal: PowerShell, Windows Terminal, bash or zsh.

Install

npm install -g https://cli.codejackrabbit.com/0.2.0/codejackrabbit-0.2.0.tgz
cjr --version
cjr doctor

Open a new terminal after installation if your shell does not see cjr yet. On Windows, if PowerShell blocks the npm shim, run cjr.cmd --version once or use Windows Terminal.

Try without installing

npx downloads the package for one run. It is handy for a quick trial, CI or an agent session; use the global npm install above for everyday work.

npx -y --package https://cli.codejackrabbit.com/0.2.0/codejackrabbit-0.2.0.tgz cjr review --local --include-untracked

First local review

cjr review --local --include-untracked
cjr review findings

Local review reads the selected Git diff. If the tree is clean, review committed work with cjr review --local --base main or cjr review --local --committed --base HEAD~1.

Connect an account (optional)

Local review needs no account. For cloud history and coding tasks, create an account, then use the CLI connection command shown once after signup.

Update or uninstall

npm install -g https://cli.codejackrabbit.com/0.2.0/codejackrabbit-0.2.0.tgz
npm uninstall -g codejackrabbit

Troubleshooting

• cjr is not recognized: open a new terminal and check npm config get prefix.
• Old Node version: run node --version; CodeJackRabbit requires Node 20 or newer.
• No changes selected: the selected Git diff is empty. Pick a base branch or review uncommitted work.
• Need agent output: add --agent for stable NDJSON events.
