Not having friends anywhere is oart of the job description of this troll. In fact, I suspect that if anyone in Canada liked him the troll in chief would quickly replace him. Just greywall him.
Hoekstra: You know, some people said, "Pete, do you have any friends in Canada?" I don't know, I've got to think about that.

FUSE sandbox experiment for greywall. Dropped Landlock for dynamic rules and JSONL observability.
"only git can touch .git/**". First match wins. Rootless. File ops stream as JSONL.
Claude can't read your .env. Git? Fine. Per-caller semantics for agent sandboxing.

I just finished testing greywall against major coding agents and various models to build a dataset for HTTP conversation reconstruction. It turns out Codex uses WebSockets for the OpenAI API. PR just merged, soon to be released ! #greyproxy #codex #ai #greyhavenhq

Linux + greywall: read .env, substitute placeholders live, write temp file, bind-mount into sandbox. Agent sees zero friction.
macOS? No bind mount. sandbox-exec doesn't support it. Looking at FUSE.

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

TIL how Homebrew tap/cask actually works. Finally sat down and figured out the formula syntax so we could ship greyproxy and greywall as proper brew casks.
Also just added settings and notifications so you never miss a pending approval when an AI agent tries something unexpected.
