Build a production agent using vibe coding with Antigravity. Learn how to implement critical security checkpoints using Model Armor callbacks. Working in small, test-driven phases. Aron shares how to intercept a user’s prompt before it hits the model to block injection attacks, and how to scrub the model’s response before it ever reaches the user to prevent data leakage.
