Just implemented credential protection in greyproxy. Instead of seeing real API keys values, the agent gets opaque `greyproxy:credential:v1:xxx` placeholders.
The proxy swaps them back before forwarding upstream. Agent never touches the actual key. #greywall #greyproxy
NVIDIA open-sourced OpenShell at GTC last week. Their big idea is out-of-process policy enforcement: the sandbox rules run in a separate process the agent can't touch. Similar #greywall. It is interesting to see the industry converging on "don't trust the agent to enforce its own rules." #aiagents
If you're sandboxing with Bubblewrap/namespaces, are you bind-mounting /run read-only? Docker, Podman, and libvirt sockets live in /run (or /var/run symlinked to /run), and Unix socket connections bypass read-only restrictions. #linux #sandboxing #greywall
