OpenClaw Antigravity CLI Harness Plugin

Registers Google's Antigravity CLI (agy) as a first-class local CLI inference backend inside OpenClaw, plus session management commands.

What it gives you

• CLI backend id agy → model refs like agy/gemini-3.6-flash-high, agy/gemini-2.5-flash.
• Commands:
  • /agy_sessions – plain-text list of local Antigravity conversations.
  • /agy_new – start a fresh Antigravity conversation and bind this chat to it.
  • /agy_resume <id|new> – list sessions, or bind this chat to a specific conversation id.

Requirements

• OpenClaw v2026.7.1+.
• Antigravity CLI installed and authenticated at ~/.gemini/antigravity-cli/ (binary agy on $PATH, OAuth token at antigravity-oauth-token).
• python3 on $PATH (used by the session-management commands).

Install

openclaw plugins install path/to/openclaw-agy-plugin-1.0.0.tgz

or from ClawHub once published:

openclaw plugins install clawhub:@buntea/openclaw-agy-harness

Usage

# point a model ref at the CLI backend
model: omniroute/agy/gemini-3.6-flash-high   # or agy/gemini-3.6-flash-high directly

# in chat
/agy_sessions
/agy_new
/agy_resume 9f4c9c2e-...   # bind to an existing conversation

Configuration

No configuration is required. All backend defaults live in the plugin and can be overridden per-agent via agents.defaults.cliBackends.agy. The session commands support environment overrides (AGY_STATE_DIR, AGY_BRAIN_DIR, AGY_PYTHON) for non-standard installs.

Development

• No build step: dist/index.js is the runtime entry. node --check dist/index.js is a fast sanity check.
• Uses only the public plugin SDK imports:
  • openclaw/plugin-sdk/plugin-entry
  • openclaw/plugin-sdk/cli-backend
