I&#x27;m excited to introduce Zerobox, a cross-platform, single binary process sandboxing CLI written in Rust. It uses the sandboxing crates from the OpenAI Codex repo and adds additional functionalities like secret injection, SDK, etc.Watch the demo: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=wZiPm9BOPCg" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=wZiPm9BOPCg</a>Zerobox follows the same sandboxing policy as Deno which is deny by default. The only operation that the command can run is reading files, all writes and network I&#x2F;O are blocked by default. No VMs, no Docker, no remote servers.Want to block reads to &#x2F;etc?<pre><code> zerobox --deny-read=&#x2F;etc -- cat &#x2F;etc&#x2F;passwd

 cat: &#x2F;etc&#x2F;passwd: Operation not permitted
</code></pre>
How it works:Zerobox wraps any commands&#x2F;programs, runs an MITM proxy and uses the native sandboxing solutions on each operating system (e.g BubbleWrap on Linux) to run the given process in a sandbox. The MITM proxy has two jobs: blocking network calls and injecting credentials at the network level.Think of it this way, I want to inject &quot;Bearer OPENAI_API_KEY&quot; but I don&#x27;t want my sandboxed command to know about it, Zerobox does that by replacing &quot;OPENAI_API_KEY&quot; with a placeholder, then replaces it when the actual outbound network call is made, see this example:<pre><code> zerobox --secret OPENAI_API_KEY=$OPENAI_API_KEY --secret-host OPENAI_API_KEY=api.openai.com -- bun agent.ts
</code></pre>
Zerobox is different than other sandboxing solutions in the sense that it would allow you to easily sandbox any commands locally and it works the same on all platforms. I&#x27;ve been exploring different sandboxing solutions, including Firecracker VMs locally, and this is the closest I was able to get when it comes to sandboxing commands locally.The next thing I&#x27;m exploring is `zerobox claude` or `zerobox openclaw` which would wrap the entire agent and preload the correct policy profiles.I&#x27;d love to hear your feedback, especially if you are running AI Agents (e.g. OpenClaw), MCPs, AI Tools locally.

Windows 95 defenses against installers that overwrite a file with an older one

This project (Agents Observe) started as an exploration into building automation harnesses around claude code. I needed a way to see exactly what teams of agents were doing in realtime and to filter and search their output.A few interesting learnings from building and using this:- Claude code hooks are blocking - performance degrades rapidly if you have a lot of plugins that use hooks- Hooks provide a lot more useful info than OTEL data- Claude&#x27;s jsonl files provide the full picture- Lifecycle management of MCP processes started by plugins is a bit kludgy at bestThe biggest takeaway is how much of a difference it made in claude performance when I switched to background (fire and forget) hooks and removed all other plugins. It&#x27;s easy to forget how many claude plugins I&#x27;ve installed and how they effect performance.The Agents Observe plugin uses docker to start the API and dashboard service. This is a pattern I&#x27;d love to see used more often for security (think Axios hack) reasons. The tricky bit was handling process management across multiple claude instances - the solution was to have the server track active connections then auto shut itself down when not in use. Then the plugin spins it back up when a new session is started.This tool has been incredibly useful for my own daily workflow. Enjoy!
