Meta's Muse agent security blueprint: freedom to act, not to rewrite permissions
TheTuringPost · x · 2026-09-16
The Turing Post breaks down Meta's personal agent Muse as a clear blueprint for agent security: Muse gets its own cloud computer to write code, build tools and run subagents, while Sentinel — a permission system outside the environment Muse can modify — checks its network requests. Real credentials sit behind surrogate tokens, data flows tighten once private info is touched, and permissions depend on what the agent has already seen. The takeaway: let agents improvise while keeping authority outside anything they can rewrite.
