Authentication

The plugin does not create or store Antigravity credentials. agy owns the login session, so sign in through agy and confirm the session with:

agy models

OpenClaw asks agy whether that login is usable, the same way it asks Claude CLI and Codex about their own sessions. In the Control UI, open Models → Providers and choose Reconnect on the Antigravity CLI card. The action checks agy models and writes those model rows onto the provider. It does not write an API key, and it does not copy the Antigravity access token, refresh token, or access-token expiry. It does not change the default model. The provider exposes no credential environment variables. A stored agy-session value on models.providers.antigravity-cli.apiKey is leftover and should be removed; openclaw doctor --fix deletes that marker, the native-auth marker, and auth profiles prefixed antigravity-cli:, antigravity:, or agy:. A different apiKey string is left unchanged. Reconnect installs or refreshes the bundled openclaw-antigravity-tool-free agy plugin. Its agent id is openclaw-antigravity-setup. OpenClaw uses that agent only for its connection probe; normal provider turns keep the configured agy mode and tool behavior.

Complete first-run setup with another inference provider when possible, then reconnect Antigravity from Models → Providers. Models-page reconnect refreshes the connection without replacing the default model.

Recovery

If a previously working session stops authenticating:

1. Run agy models as the Gateway user.
2. If that command reports an expired or missing session, complete the login

flow in agy; do not paste an API key into OpenClaw for this provider.

1. Run agy models again before retrying OpenClaw.
2. In the Control UI, open Models → Providers and choose Reconnect on

the Antigravity CLI card.

1. If the command works interactively but not in the Gateway, configure an

absolute command path and verify both processes use the same OS account and environment.
