Google Antigravity Provider for OpenClaw

Production-ready OpenClaw plugin for delegating persistent agent turns and model routing to a local signed-in Google Antigravity (agy) CLI. Compatible with OpenClaw 2026.8.x+.

Features

Persistent Multi-turn Agent Sessions: Full SQLite conversation caching and automatic resume binding across turns.
Dynamic Configurable Timeouts: Automatically derives --print-timeout dynamically from timeoutSeconds or custom plugin settings (default: 30m0s), preventing premature agent turn termination.
Full Model Support: Gemini 3.7 Flash (High / Medium / Low), Gemini 3.6 Flash (High / Medium / Low), Gemini 3.5 Flash, Gemini 3.1 Pro (High / Low), Claude Sonnet 4.6 (Thinking), Claude Opus 4.6 (Thinking), GPT-OSS 120B.
Synthetic Local Auth: Seamlessly uses local signed-in agy credentials with zero expiring tokens or stored secrets in OpenClaw.
Sanitized Execution Environment: Automatically isolates user data via ANTIGRAVITY_USER_DATA_DIR and scrubs conflicting ambient Google API keys.
Preflight Probing: Validates local agy CLI health, executable availability, and required command-line flags on setup.

        "/home/rev/projects/openclaw-google-antigravity-provider"
      ]
    },
    "entries": {
      "google-antigravity-cli": {
        "enabled": true
      }
    }

Optional: Real-Time Thought & Text Streaming

To stream thinking and response deltas in real-time to the OpenClaw Web UI, enable stream: true under agents.defaults.cliBackends.google-antigravity-cli:

json

{
  "agents": {
    "defaults": {
      "cliBackends": {
        "google-antigravity-cli": {
          "stream": true
        }
      }
    }
  }
}
