Antigravity for Claude Code
A Claude Code plugin that delegates scaffolding, test generation and other bulk work to the Antigravity CLI running Gemini as a sub-agent, while Claude keeps the judgment calls.
Antigravity for Claude Code is a community plugin, not affiliated with Google or Anthropic, that runs the Antigravity CLI (backed by Gemini) as a collaborating sub-agent inside Claude Code. It routes work across the development lifecycle so Claude handles requirements, architecture, verification and review while Antigravity and Gemini handle scaffolding, implementation, test generation and search.
It adds tools Claude lacks natively, such as Google web search, Vertex AI Search over internal data and Cloud Logging, and can process audio and video by delegating perception to Gemini and returning a timestamped digest instead of a raw transcript. It supports cross-model verification, background jobs, and an internal fan-out where the delegated agent can spawn its own subagents, plus a SessionStart hook that installs a cost-aware routing policy automatically.
