Testing AI Safety Guardrails: Input/Output Filter Validation, PII Detection, and Adversarial Jailbreak Testing
AI guardrails are the safety layer between user input and your language model. They block prompt injections, filter inappropriate content, redact PII from outputs, and resist jailbreak attempts. They're also the part of your AI system that's most likely to be skipped in testing. The reasoning

How to QA Test What Devin Builds
Devin AI can write code, run tests, and ship pull requests autonomously — including QA-testing the changes it makes. But self-testing has a fundamental limitation: Devin tests what it built, not what it might have broken. Independent behavioral tests running continuously in production catch the regressions Devin's
