Current controls fail to address risks that arise from the sequence of authorized actions, as demonstrated in incidents like the Superbase and Cursor attacks. Flint implements a two-layer system: a role-based access control layer and a behavioral detection layer that tracks data flow across tool calls. I have already built the role-based detection and several behavioral detection rules, and I am currently working on an inline gateway to enhance security. I encourage you to provide feedback on these developments as we move forward."}
