AI agents can generate code at a scale that’s hard for humans to review line-by-line. PDD Kit helps ensure the code is doing what the developer intended by creating formal specifications and testing against them. It converts developer intent into a Verus specification, proves AI-generated code meets it for every input, and uses tests where proofs aren't practical. Developers review…

Excerpt from the source

At a glance Formal methods for everyday software. PDD Kit helps you turn your intent into a formal spec, then proves the code your agent writes for every input and uses tests where a proof can’t reach. It takes formal methods beyond niche, specialist work to engineers without a formal methods background and to everyday applications, like the full-stack web app shown here. Exhaustive line-by-line human review can become difficult to scale as AI agents generate increasingly large amounts of code.…

Lazare, veni foras: Reprogramming Dormant Neurons to Backdoor AI Agents

Microsoft researchers have discovered “Lazarus,” a backdoor technique that can reprogram dormant neurons in an AI model, causing an otherwise normal AI agent to execute malicious commands when a hidden trigger appears. The threat is especially serious for AI agents with tool or terminal access. A triggered model could quietly download and run attacker code, […] The post Lazare, veni…
