Antigravity

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

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 your first Palabre configuration, open palabre again or synchronize explicitly:

palabre config --sync-agents

Gemini Transition

Google announced the transition from Gemini CLI to Antigravity CLI for individual users, while Enterprise customers retain access according to their licenses.

Official reference: Transitioning Gemini CLI to Antigravity CLI

Palabre no longer generates Gemini CLI in new configurations and no longer exposes it in presets. The old Gemini notes are kept in Gemini notes for context.

JSON Configuration

The configuration generated by Palabre looks like this:

Excerpt from the agents block:

"antigravity": {
  "type": "cli-pty",
  "command": "agy",
  "args": ["--print-timeout", "5m0s", "--print"],
  "promptMode": "argument",
  "role": "reviewer",
  "tier": "primary",
  "timeoutMs": 300000
}

Examples

palabre codex-antigravity "Compare this architecture approach" -t 4
palabre antigravity-ollama "Critique this migration plan" -t 3

Limits and quota

Official documentation: Antigravity CLI — headless mode.

A standalone quota message such as “Individual quota reached” in a short output is classified as usage-limit, even with exit code 0. It is not treated as a normal answer. The prompt is a command-line argument and may exceed the command-line size, especially on Windows. PALABRE defaults bound calls to 5 minutes (timeoutMs and --print-timeout); adjust both together. The PTY merges stdout and stderr. Antigravity is not a Relay target.
