Could you build this?

Partial The dashboard, policy configuration, and CLI are vibe-codeable, but kernel-level sandboxing (eBPF/Landlock) and reliable prompt-injection defense require security engineering expertise that a prototype won't reach.

What it would actually take: The stack would be a Rust or C daemon with eBPF programs and Landlock LSM rules for syscall and filesystem restriction, plus a local proxy or hook layer for agent tool calls. The hard parts are correct kernel-level enforcement that resists bypass and a prompt-injection detector with a low false-positive rate. Building it credibly needs systems and security researchers, along with adversarial testing against real agent workflows.
