Zero for Claude Code (CLI)

How to install Zero in the Claude Code CLI and keep it up to date.

Using the desktop app? See the Claude Code Desktop guide. Using Claude on the web or your phone? See the claude.ai guide.

Install

Inside Claude Code

Inside a Claude Code session, run:

/plugin marketplace add officialzeroxyz/zero-plugins
/plugin install zero@zero-plugins
/reload-plugins

From the terminal

claude plugin marketplace add officialzeroxyz/zero-plugins
claude plugin install zero@zero-plugins

That's it — Zero sets itself up automatically. Ask Claude: "Help me set up and test Zero." It walks you through signing in.

Staying up to date

Nothing to do — updates are automatic:

• The Zero runner updates at the start of each session.
• The plugin itself checks for updates once a day, in the background, and they apply the next time you start Claude Code.

To turn off the daily plugin check, set ZERO_PLUGIN_AUTOUPDATE=0 in your environment.
