Build Firebase AI Apps with Antigravity CLI and Stitch MCP

A developer demonstrates using Antigravity CLI, an agentic AI assistant, to build an image analysis app with Angular, Firebase Hybrid & On-device Inference SDK, and Gemini models. The app uses on-device Gemini Nano in Chrome 148+ for zero-token inference, falling back to cloud Gemini 3.5 Flash in other browsers. The workflow integrates Stitch MCP server for design-to-code generation and skills like grill-with-docs and angular for best practices.
