Building an Agentic Telegram Bot in Ruby with Google's Antigravity SDK

This article details the creation of an unofficial Ruby SDK for Google's Antigravity harness, which powers Gemini CLI and IDE. It explains the architecture (Ruby process communicating with a Go binary via WebSocket), shows how to set up an agent in five lines, and demonstrates building a Telegram bot with per-chat sessions. The bot can discover and load skills at runtime, enhancing its capabilities dynamically. The article also covers the Agent Skills standard, local and GitHub-based skill paths, and the debugging journey, including a mysterious silence after seven WebSocket messages. It's a technical guide for Ruby developers interested in integrating agentic AI into their applications.
