6 months back I started dockerizing my setup after multiple npm vulnerabilities.
Then I wrote a small tool[1] to streamline my sandboxing.
Now, I run agents inside it for keeping my non-working-directory files safe.
For some tools like markdown linter, I run them without network access as well.
I would like to see more articles about agent sandboxes. With agents gaining popularity we need a higher fraction of users to understand containers and sandboxes and their risk profiles, and then to communicate their understandings to friends and family. It is a harder task than explaining ChatGPT, and it often feels like a hindrance.
Hugged to death? Seeing SSL failure to the site from CloudFlare.
The secret proxy trick is something I expect to become standard at some point in the near future. I first saw this trick being used in Deno Sandboxes (https://docs.deno.com/sandboxes/security/) but it's cheap/easy to implement so I'd be surprised if this doesn't become the standard for a lot of these BaaS platforms.
