If you are using Claude Code on macOS running it in a devcontainer has a few upsides like fewer cli tool call failures, meaning less waiting time and less context window spam.

But there are some things you lose as well @ ergonomics:

- "done" notifications are not working by default (might be possible trigger and send to host using hooks feature)

- more difficult to give playwright a session (need to get cookies into playwright in the container)

- can't easily paste screenshots into the devcontainer (Claude Code has to take a screenshot or you have to put it into a mounted dir)

and of course the usual advantages of using containers still apply (dependency management, reproducibility and so on).

I still wonder though if nix would allow me to remove the container overhead (they do noticeably tax the macbook battery).
