MICROSOFT has unveiled two open-source tools, RAMPART and Clarity, to help developers test the security of AI agents during development. RAMPART, short for Risk Assessment and Measurement Platform for Agentic Red Teaming, is a Pytest-native framework for writing and running safety and security tests that cover adversarial and benign issues as well as various harm categories.

Clarity is described by Microsoft as a structured sounding board—an AI thinking partner that guides problem clarification, solution exploration, failure analysis, and decision tracking. Together, the tools aim to address decisions made early in software development so that potential issues, such as an agent’s access to a tool, can be mitigated before the system is built.

“We wanted to give product managers and engineers a way to pressure-test their assumptions at the start of a project, when changing course is cheap and the right conversation can save months of rework,” the article quotes Ram Shankar Siva Kumar, a Data Cowboy and founder of Microsoft’s AI Red Team.
