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, authentication, native tools, and automatic compaction. Each turn runs agy --print --output-format stream-json; follow-up turns resume the agy conversation id. The plugin stores no API key and does not replace the Antigravity CLI login flow.

OpenClaw displays incremental response text and native tool starts/results. Tool events report actions already performed by agy. They do not execute OpenClaw tools or establish OpenClaw message-delivery evidence.

Use models as antigravity-cli/<model>. agy models is the source of truth for which models the signed-in account can run. Effort suffixes on those rows are not part of the OpenClaw model id. Discovery refreshes the catalog from agy models. Reconnect writes those rows into the provider config. Thinking level is passed as agy --effort, limited to the levels agy models lists for the model. Models without effort variants omit that flag. Legacy Opus 4.6 uses claude-opus-4-6-thinking; current Opus models use their catalog id.
