Why AI Agent Failures Are Harder To Detect Than Software Bugs

One thing becoming increasingly obvious while testing AI agents:

Traditional software usually fails loudly.

You get:
• crashes
• errors
• exceptions
• visible signals

AI agents are different.

They can:
• continue operating
• sound correct
• complete workflows
• appear functional

…while behaving incorrectly underneath.

That creates a difficult reliability problem because silent failures are harder to detect than visible ones.

This is one of the reasons we started building Crucible:

“Pytest for AI agents.”

Open-source security testing and behavioral evaluation for agentic systems.
