Summary
AI systems need security and permissions testing baked into every eval, not just functionality checks. People actively try to jailbreak AI or extract system prompts, and a model or prompt upgrade can silently break guardrails that worked fine yesterday.
Core ideas
- Security as a test category: Permissions and security need dedicated slots in AI eval suites, sitting alongside functionality tests, not as an afterthought.
- Adversarial users exist: People deliberately probe AI systems to extract system prompts or push them off-topic, so this behavior has to be assumed and tested for.
- Regression testing matters: Every model upgrade or prompt change needs a fresh security pass, since past security guarantees don't carry forward automatically.
- Guardrails are fragile: A model swap or prompt tweak can quietly break protections that took real effort to build, without any obvious signal that it happened.
- Continuous vigilance over one-time checks: Security testing isn't a setup step you finish once. It's a repeated part of the release cycle for any AI application.
Quotes
“I know I'm one of those people that as soon as I see it's AI, I want to see if I can get a system prompt in or get it to answer some random question for me.”
“a prompt change or a model change may allow the model to break out of its guardrails that you've spent so much time setting up”
