About

The Google Antigravity SDK is a Python library for building agents with Antigravity and Gemini. An Agent class manages the runtime lifecycle, tool wiring and policy defaults inside an async context manager, and responses can be streamed as text, reasoning and tool-call events. Agents start in read-only mode, and tools that write need an explicit capabilities config. It runs against the Gemini API with an API key, or against Gemini Enterprise Agent Platform (formerly Vertex AI) with a project and location.
