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.
Here's what I use it for right now
- yarn - npm - pnpm - mdl - Ruby-based Markdown linter - fastlane - Ruby-based mobile app release tool by Google - Claude Code - Gemini CLI
Over time, my goal is to run all CLI-based tools that only need access to the current directory (and not parent directories) via this.
