Google rolls out an Antigravity plugin marketplace

What happened?

Google announced a plugin marketplace for the Antigravity app and command-line interface on October 29. It describes a directory of Google-built and third-party integrations intended to simplify connecting coding agents to external tools and services.

According to Google, plugins can package skills, Model Context Protocol server configurations, rules, lifecycle hooks and specialized agents. The company says users can browse plugins in the app or install them through the CLI, and describes the marketplace as rolling out across both surfaces.

The announcement lists integrations spanning developer tools, cloud platforms and productivity services. It does not establish that every account already has the marketplace, that all integrations are free, or that any particular plugin has been independently audited.

Why does it matter?

Packaging setup can make an agent easier to connect to real work, but it can also bundle access to sensitive systems and executable hooks. Before installation, review the publisher, requested permissions, authentication, configuration and any scripts against your organization’s security policies.

Update November 2: Android CLI adds an official Antigravity integration

Android's own documentation now supplies a concrete example of the marketplace's work surface. Android CLI is described as an official plugin for Google Antigravity, Claude Code and Codex, and the Antigravity integration includes Compose Previews and Device Hub connections for local or remote devices. Android's October announcement also places Gemini 4 Argon access in Android Studio Canary for Google AI Ultra subscribers.

This is narrower than the other rumors attached to the lead. The reviewed first-party pages document Android tooling, agent skills and integrations; they do not confirm a newly launched local-versus-cloud task switch or an agent called “Chief of Stuff.” Those claims stay out of the update rather than being mapped to documented Antigravity features by implication.

For work teams, the practical issue is now less whether an Android connection exists and more what the plugin can access in a given setup. Device connections, previews and agent instructions can expose source code, build outputs and test devices. Review publisher, permissions, authentication and local/remote routing before installing, and treat the AI Ultra requirement as a documented eligibility condition rather than a general Antigravity entitlement.
