Circle Internet Financial's Circle Research team has released an extension for the OpenAI Agents SDK, introducing the @secure_tool decorator to enhance security in AI agent actions and workflows, particularly for blockchain applications. This tool aims to automate user approval processes to prevent errors such as AI agents mistakenly sending cryptocurrency to incorrect addresses. The @secure_tool ensures that every transaction aligns with user intent by using hooks that check permissions before execution and report results afterward. The WorkflowManager class orchestrates a sequence of actions, facilitating secure and orderly execution of blockchain operations. This innovation is part of Circle's broader initiative to foster discussions on secure agentic design and is available as an open-source project for developers to explore and test.
