Antigravity CLI for Codex

Use a local Google Antigravity CLI (agy) from Codex for independent review, research checkpoints, planning critique, one-shot agent tasks, model discovery, plugin management, and agentapi passthrough.

Prerequisites

• Codex with plugin support enabled
• Node.js 18 or newer
• A working, authenticated agy installation available in PATH, or an ANTIGRAVITY_BIN environment variable pointing to the executable

The plugin does not install or authenticate agy for you.

Install

Run:

codex plugin marketplace add mrlong0129/antigravity-cli
codex plugin add antigravity-cli@mrlong0129

Then start a new Codex task and ask:

Use Antigravity CLI to check my agy status.

Install with a Codex prompt

Copy this into Codex:

Install the Codex plugin from the GitHub marketplace mrlong0129/antigravity-cli.
Add the marketplace, then install antigravity-cli@mrlong0129. Verify that the
plugin appears in `codex plugin list --marketplace mrlong0129`. Do not modify any
other plugins. If `agy` is not installed or authenticated, report that clearly
instead of attempting to install or log in to it. When installation succeeds,
tell me to start a new Codex task and ask: "Use Antigravity CLI to check my agy
status."

What it exposes

• status: locate agy, report its version, and inspect optional agentapi state
• run: launch a bounded one-shot Antigravity task
• checkpoint: request critique at framing, research, planning, implementation, or final-review stages
• models: list Antigravity models
• plugin: pass through to agy plugin
• agentapi: pass through when ANTIGRAVITY_LS_ADDRESS is available

Security

The wrapper starts the locally installed agy process with the current environment and working-directory permissions. Review Antigravity's own permissions before allowing write, credential, deployment, or broad filesystem operations. The plugin does not bundle credentials.
