Think about how software engineering evolved.
There was a time when applications shipped without automated tests.
Eventually, unit testing became a standard expectation.
Not because it was fashionable.
Because it reduced failures.
AI engineering is approaching a similar moment.
Modern AI agents don’t just generate text.
They call tools.
They access APIs.
They retrieve memory.
They make decisions.
Those behaviors deserve automated validation.
Imagine opening a pull request and seeing not only your unit tests pass…
…but also confirmation that your AI agent still resists prompt injection, respects tool boundaries, behaves consistently, and hasn’t introduced new security regressions.
That future isn’t as far away as it might seem.
We believe AI security testing will become another essential layer of modern software engineering.
That’s the direction we’re building toward with Crucible.
Pytest for AI Agents.
