- Microsoft has launched two new open-source security tools, RAMPART and Clarity, designed for AI agent development.
- RAMPART is a testing framework for running safety and security tests on AI agents, building on the earlier PyRIT platform.
- Clarity acts as an “AI thinking partner” to help developers clarify design intent and pressure-test assumptions before coding begins.
- The tools aim to shift AI safety from a one-time review into a continuous, integrated part of the development lifecycle.
On May 20, 2026, Microsoft unveiled two open-source tools, RAMPART and Clarity, to help developers integrate security testing directly into the workflow for building artificial intelligence agents.
RAMPART functions as a specialized testing framework for probing AI agents for vulnerabilities like cross-prompt injections and data exfiltration. Consequently, it evaluates test outcomes and reports results, requiring only an adapter to connect an agent to the test suite.
Meanwhile, Clarity is described as a structured sounding board that guides developers through problem clarification and solution exploration before any code is written. This “AI thinking partner that pushes back” aims to catch potential issues when changing course is still inexpensive.
In a blog post, Microsoft’s Data Cowboy Ram Shankar Siva Kumar explained the motivation was to pressure-test assumptions early. He stated, “We wanted to give product managers and engineers a way to pressure-test their assumptions at the start of a project.”
The secondary goal is to make security incidents reproducible and scale learnings from red teaming into runnable engineering assets. Therefore, these tools represent a shift from post-build discovery to integrated safety throughout an AI system’s lifecycle.
