Humans Verify. AI agents comply.

Many AI agents are optimized to be helpful.

That sounds good.

Until a manipulated instruction arrives.

Humans naturally verify requests.

AI agents often comply with them.

That's why prompt injection continues to be one of the most important security challenges in agentic systems.

We built Crucible to help teams test exactly these scenarios.

"Pytest for AI agents."

Open-source security testing for:

• prompt injection
• behavioral failures
• adversarial evaluation
• agent monitoring
