What is agy plugin for Claude Code?
The agy plugin for Claude Code is an open-source Claude Code plugin that wraps the Google Antigravity CLI (agy) so you can call Gemini/agy features directly from inside Claude Code without leaving your editor. It exposes six slash commands and a forwarding subagent so users can run one-shot prompts, delegate tasks or long-running jobs to a runner, perform structured deep research with citations, request second-opinion code reviews from a different model, and generate images via agy's built-in Imagen tool. The plugin is a small Bash wrapper (no Node runtime or external broker), designed to be installed quickly from the Claude Code plugin marketplace and to verify/install agy automatically during setup. It targets developers and technical users who want seamless cross-model workflows inside Claude Code — for example, switching between Claude and Gemini for research, code review, refactors, or image generation — while keeping everything local, auditable, and MIT-licensed.
agy plugin for Claude Code pricing
Pricing model: Freemium
The website describes the plugin as open-source and MIT-licensed with no charge for the plugin itself; any pricing or quota implications come from the underlying Antigravity/Gemini provider (agy) and the models you call, so free-tier vs paid usage depends on agy/Gemini account plans rather than the plugin. The plugin offers a free, installable wrapper and does not list paid plans of its own.

Frequently asked questions about agy plugin for Claude Code
What does antigravity-plugin-cc actually do inside Claude Code?
It wraps the local Antigravity CLI (agy) and exposes six slash commands plus a forwarding subagent so you can run agy one-shot prompts, delegate tasks (foreground or background), run structured research briefs with sources, generate images via Imagen, and request git-diff-aware code reviews — all without leaving Claude Code.
How do I install the plugin in Claude Code?
Follow the three-step install: register the marketplace with /plugin marketplace add simplybychris/antigravity-plugin-cc, install the plugin with /plugin install agy@antigravity-cc, then reload and run /agy:setup to verify install and auth; each step is shown on the site with one-click copy commands.
Does the plugin include or run a remote service?
No — it is a pure Bash wrapper around your local agy binary and does not run a hosted broker or remote service; you keep agy and credentials local and the wrapper merely calls the binary and marshals results into Claude Code.
Which commands does the plugin add to Claude Code?
It adds /agy:setup (install/auth check), /agy:ask (one-shot prompt), /agy:delegate (hand off tasks to agy:runner with --background or --model), /agy:research (structured deep research with sources), /agy:image (Imagen image generation with --name and --output options), and /agy:review (git-diff code review with optional focus).
Can I run long-running jobs in the background?
Yes — the plugin supports a runner subagent and a --background option so you can delegate long jobs (research, refactors, CI investigations) and receive notifications in Claude Code when they finish.
Is there any runtime or Node dependency?
No — the wrapper is pure Bash and intentionally has no Node runtime dependency; it aims to be lightweight and compatible with macOS Bash 3.2 and similar environments.
What models can I call through the plugin?
You call whatever models are available through your local agy/Antigravity setup — the plugin supports per-call model selection via the --model flag, enabling use of Gemini or other models routed through agy.
How does the /agy:review command work with my git changes?
/agy:review pipes the current git diff into agy and asks for a steerable, model-powered second opinion; you can add optional focus text to narrow the review to security, style, tests, or specific files.
Is the plugin open source and can I modify it?
Yes — the plugin is published under the MIT license, the Bash wrapper is auditable and forkable, and the repository accepts issues and pull requests for contributions or customization.
What happens if agy or Gemini changes upstream?
Because the plugin is a thin wrapper around the local agy binary, upstream changes to agy/Gemini may require plugin updates; the site notes versioning and encourages users to track releases and update the plugin when needed.
