Antigravity for OpenClaw

@cavi-ai/antigravity connects OpenClaw to Google's Antigravity CLI (agy) as a subscription-backed model provider. The plugin id is antigravity; the model provider and CLI backend id is antigravity-cli.

This is an external plugin. It is separate from OpenClaw's bundled google-antigravity provider and from the unrelated unscoped npm package openclaw-antigravity.

Runtime boundary

OpenClaw owns the conversation presented to the plugin. agy owns inference and authentication. Each turn runs agy --print with JSON output; follow-up turns resume the agy conversation id. The plugin stores no API key and does not replace the Antigravity CLI login flow.

Use models as antigravity-cli/<model>. The model id is handed to agy, which is the source of truth for the models available to the signed-in account.
