Build a Google Antigravity Agent in Slack for Trello Queries

This tutorial shows how to create a stateful Slack agent using Google's Antigravity managed agent to answer complex questions about Trello boards. It implements a zero-exposure security architecture that injects API credentials via egress proxy transformations, preventing credential leaks. The agent dynamically writes and executes scripts in a sandboxed environment to parse Trello data and generate formatted responses.
