zeyxx/hermes-antigravity
Hermes Antigravity is a native inference-provider plugin that integrates Google Antigravity / Cloud Code Assist into Hermes Agent as a ProviderProfile, giving full streaming, native tool/function calling and reasoning-token support for the Gemini and Claude models it exposes. Its stated purpose is unlocking consumer and student Google AI subscriptions - Gemini Pro Student, Gemini Advanced, Google One AI Premium, Google Workspace for Education - none of which Google issues API keys for, so Hermes previously could only reach Google models through paid Google AI Studio keys or Vertex AI service accounts. The plugin instead authenticates directly with the user's Google account through OAuth 2.0 with PKCE and calls Google's internal Cloud Code Assist streaming endpoint, so subscription quota is used instead of metered API billing. Internally the plugin is a Python port of an existing pi-antigravity extension originally written for the Pi Coding Agent, re-architected around Hermes's provider interface while keeping the same wire protocol, model routing and session handling. Its documented architecture splits authentication and token refresh, translation between the OpenAI-style chat completions interface Hermes expects and Google's internal request/response format including server-sent-event parsing and tool/thinking-token handling, and an HTTP transport layer with failover between Cloud Code Assist endpoints. The project ships an MIT license, targets Python 3.10+, and provides both English and French README translations. Because it depends on the same reverse-engineered internal API surface as its Pi Coding Agent predecessor, it is explicitly acknowledged as unofficial and dependent on undocumented Google endpoints that could change without notice.
