Antigravity

Antigravity CLI can be used as a Palabre agent through the agy command.

Unlike batch agents such as Gemini CLI, Antigravity needs the cli-pty adapter: in testing, agy --print answers in a real console but does not produce capturable stdout when launched with plain Node pipes.

Installation

Install Antigravity CLI from Google's official documentation, then check that the command is available:

agy --help

If Antigravity was installed after palabre init, synchronize the configuration:

palabre config --sync-agents

Gemini Transition

Google says Gemini CLI will stop serving requests for free individual users and Google AI Pro/Ultra users on June 18, 2026, while Enterprise customers keep access according to their licenses.
