HOW WE BUILT SAFETY INTO MUSE

Summary from the TLDR Dev newsletter

Muse runs in a dedicated cloud VM where the agent operates inside an isolated runtime cell and never sees real credentials. A separate Sentinel controls connector actions and network egress, while host-side services enforce least privilege, approval scopes, and prompt injection defenses. The design assumes the agent can make mistakes or process hostile data, then limits the damage through layered boundaries and a public bug bounty.
