Developed a Secure Tool Execution Approval System for the microsoft/agent-framework repository, focusing on backend development and security best practices using Python. The work introduced a server-side registry to track approval requests, ensuring that only validated and authorized tool executions occur. By validating approval responses against server-stored function call data and consuming request IDs upon use, the system effectively mitigated risks of forged or replayed approvals. Comprehensive testing was implemented to cover scenarios such as forged rejections, server-data enforcement, and anti-replay protections. This feature enhanced the reliability, auditability, and compliance of the tool execution workflow within the project.
