Automatic update failed

[YutaroYamada]

I'm having trouble with automatic updates for Claude Code. My devcontainer uses a file like this:

devcontainer.json
docker-compose.yml

Hello!

This is happening for me as well when using a non-root user for spawning processes in the container (i.e., via the remoteUser setting in devcontainer.json).

If my user in the container is root (e.g., by setting "remoteUser": "root"), then auto-updating works because the owner of the @anthropic-ai install directory (in npm root --global) will be root (because feature installation scripts are run as root):

drwxr-xr-x 3 root root 4096 Nov 27 05:38 @anthropic-ai

However, if I use a non-root user (e.g., "remoteUser": "vscode"), then I no longer have write permissions to the directory, since the owner is root and the directory is not group-writable:

drwxr-sr-x 3 root   nvm 4096 Nov 27 05:48 @anthropic-ai

One solution is to make Claude Code's install directory group-writable. This would be consistent with how the Node.js feature does it, which makes everything group-writable, and also discussion in the devcontainers org.

Another option is to detect the non-root user via environment variables.
