100% agree a FUSE mount would be the way to go given more time and resources.

Putting Chroma behind a FUSE adapter was my initial thought when I was implementing this but it was way too slow.

I think we would also need to optimize grep even if we had a FUSE mount.

This was easier in our case, because we didn’t need a 100% POSIX compatibility for our read only docs use case because the agent used only a subset of bash commands anyway to traverse the docs. This also avoids any extra infra overhead or maintenance of EC2 nodes/sandboxes that the agent would have to use.

Yah my Claude Code agents run a ton of Python and bash scripts. You're probably missing out on a lot of tool use cases without full tool use through POSIX compatibility.

agreed. hopefully we can get there soon

Did you guys look at Firecracker-based options such as E2B and Fly.io? We’ve had positive early results on latency, but yeah … too early to tell where we end up on cost.

Yea we did and actually use Daytona for another product, but it would have been too slow here.

Makes sense, thanks for clarifying!
