neerazz/hermes-antigravity-oauth
hermes-antigravity-oauth lets Hermes Agent use models available on a Google Antigravity plan, including Gemini 3.x, Claude 4.6 and GPT-OSS, by delegating every model call to Google's own agy command-line binary rather than talking to any API directly. Installed with a single npx hermes-antigravity-oauth command, the plugin registers itself with Hermes and starts a sign-in through agy's native browser OAuth flow (hermes auth add antigravity-oauth), which it then verifies live by calling agy models; over SSH the user pastes the device code back manually. The resulting token is never read, copied or stored by the plugin itself: it stays wherever agy already keeps it, in the OS keychain or agy's own token file. To let each isolated agy subprocess reuse that login, the plugin runs every call in a private temporary HOME and symlinks in only the specific credential file (and, on macOS, the Keychains directory) agy needs, checking the OS keyring only for the credential's existence before spawning, never reading its contents; the temporary HOME is deleted when the session ends. Hermes' own persona file (SOUL.md) is written into that private workspace each turn as GEMINI.md so agy treats it as first-class instructions. Because agy ships its own built-in tools, the plugin intercepts any tool call agy's model attempts and re-issues it as the equivalent Hermes tool (file read/write, search, terminal, web search and extraction), so execution stays inside Hermes' own approval and sandboxing rules rather than running natively under agy. Releases are automated: every push to main runs the Antigravity-side test suite against Hermes Agent's own main branch before publishing a provenance-signed npm package via GitHub OIDC trusted publishing, so the repository itself stores no npm credentials. The plugin is MIT-licensed and credits an earlier streaming-client implementation it builds on.
