I use a bunch of different coding agents but they always have annoying permission pop-ups or not the right kind of sandboxing. I wanted something simple and flexible so I made it over the weekend.

You use it like so:

- Get the binary in whichever way you like (you can use Nix, Mise or just get it through the releases page).

- Configure via `.agent-run/config.toml` to make the folders you care about read-write, and add any environment variables.

- Run your agent like so: `agent-run <pi|claude|codex|opencode>`.

It's very generic so technically you can use this for any command.

Currently only supports Linux because I don't have access to a macOS machine and sandbox-exec looks daunting.

If you back it through smolvm, I can take care of the isolation story for you across windows, macOS
