Developer Builds Stateful AI Image-Editing Skill for Google Antigravity Using Gemini API
A developer has released nb2lite-skill-agy, an open-source project that wraps Google's Gemini image model inside a FastMCP server and integrates it as a skill for the Antigravity CLI tool. The project leverages Google's Interactions API, which preserves visual context between turns, allowing users to iteratively edit an image with short follow-up prompts instead of re-describing the full scene each time. The underlying model, gemini-3.1-flash-lite-image, supports sub-two-second image generation and text rendering in over 25 languages. The integration is built on the Model Context Protocol, an open standard that lets any compatible AI assistant discover and use the tool without custom per-client code. The repository ships both an MCP server exposing four tools and a skill definition that instructs Antigravity when and how to invoke them during a coding session.
