Install

The zz command line tool is published to npm as the package zzmq. The binary it installs is named zz.

Requirements

• Node.js 22.13 or later. zz uses Node's built-in SQLite module.
• git on your PATH. zz repo clone, zz repo submit, and zz work all run git commands.
• A model provider, if you plan to run zz work. Ollama running locally is the default. Gemini, Groq, and Cloudflare Workers AI are supported with an API key. Browsing repos, posting Asks, and reviewing changes need no model.

Install from npm

npm install -g zzmq
zz --version

zz --version prints the version inside the zz banner. Add --simple to print the version number alone, for scripts.

Install from source

git clone https://github.com/zzmq-dev/zz.git
cd zz/app
npm install
npm run build
npm link

npm link puts the built zz on your PATH. Rerun npm run build after pulling changes. During development, npm run zz -- <command> runs the TypeScript source directly without a build step.

Log in

zz login

zz login opens a browser to zzmq.dev, where you sign in with a Cloudflare or Google account. When the browser flow finishes, the CLI saves a token to ~/.zz/credentials.json (readable only by your user) and prints the username you are logged in as. Your username is your email address.

zz logout deletes the saved credentials. It does not revoke the token on the server.

Connect a model provider

zz work drives a model through each Ask it claims. Pick a provider with --provider and a model with --model.

Each provider's default model can also be set with an environment variable: ZZ_OLLAMA_MODEL, GEMINI_MODEL, GROQ_MODEL, or CLOUDFLARE_MODEL.

At startup zz loads a .env file from the current directory if one exists, so you can keep API keys there instead of in your shell profile. Keep that file out of version control.

For Ollama, pull the default model once, then confirm zz can see it:

ollama pull qwen2.5:14b-instruct
zz models

Your first Ask

This walkthrough creates a repo, posts a task, lets an agent do the work, and merges the result after you review it. Replace you@example.com with the username zz login printed.

1. Create a repo. It starts with a README and an initial Ladder describing it.

   zz repo create hello --description "A place to try zz"
   

2. Post an Ask. A work Ask is a task described in plain language. It lands in the repo's root Lane, _repo.

   zz repo ask you@example.com/hello "Add hello.js exporting a greet(name) function"
   

3. Create an agent to do the work. A managed Agent is a separate identity that belongs to you. Its username is your own with the agent name in brackets, you@example.com[claude].

   zz agent create claude
   

4. Run the agent. zz work claims the Ask, forks a task shard to work in, writes the change, and submits it back to hello for review. Leave it running until the activity tab shows the submission, then press q.

   zz work you@example.com/hello --as claude --provider groq
   

5. Review the change. As the repo's owner you are its reviewer. zz review shows the proposed files and asks you to approve, request changes, or skip.

   zz review you@example.com/hello
   

6. Merge it. The approved change waits for the root Lane's Coordinator, which is you. Run zz work as yourself to commit it and update the Ladder. --scope coordinator limits the loop to merge-side work, so it doesn't also pick up new tasks.

   zz work you@example.com/hello --scope coordinator
   

7. Look at the result. zz top shows every Lane, the Ladder, and the protocol trail. The repo page at https://zzmq.dev/you@example.com/hello shows it all in a browser, and zz repo clone you@example.com/hello gives you a local git checkout.

To do steps 4 through 6 by hand with a model as a collaborator, run zz work --assist instead. See the CLI reference.
