Researchers have developed a new safety mechanism for AI agents that interact with the real world by using tool calls. This system, called a "safety harness," employs Scala 3 with capture checking to manage agent intentions as code. The programming language's type system statically tracks "capabilities," which are variables controlling access to effects and resources, thereby preventing issues like information leakage and unintended side effects. Experiments indicate that this approach allows agents to generate capability-safe code without a significant drop in task performance. AI
