There was a problem hiding this comment.
Hey - I've found 1 issue, and left some high level feedback:
- The new home-directory fallback in
create_claude_directoriesthat ultimately uses/tmpcould lead to unexpected config placement and permission issues; consider failing fast (with a clear error) if no valid home can be resolved instead of writing to/tmp. - With the hard-coded default
ARG PIXI_VERSION=v0.62.2in the Dockerfile, it's easy for this to drift from the version tracked inpixi.lock; consider deriving this from a single source of truth or documenting the coupling so updates don't get out of sync.

**🚨 suggestion (security):** Falling back to /tmp for config directories can cause surprising behavior and potential permission issues
Using `/tmp` as the last fallback puts user config in a world-writable, ephemeral directory, which is both surprising (config lost on reboot/container restart) and potentially unsafe, depending on how `/tmp` is managed. Prefer failing with a clear error once `$HOME` and `/home/${target_user}` are unavailable, or requiring `_REMOTE_USER_HOME` to be set explicitly, rather than silently defaulting to `/tmp`.
```suggestion
# Determine the target user's home directory
# $_REMOTE_USER is set by devcontainer, fallback to 'vscode'
local target_user="${_REMOTE_USER:-vscode}"
local target_home="${_REMOTE_USER_HOME:-/home/${target_user}}"
# Be defensive: if the resolved home does not exist, fall back to $HOME,
# then to /home/${target_user}. If neither is available, fail clearly.
if [ ! -d "$target_home" ]; then
if [ -n "${HOME:-}" ] && [ -d "$HOME" ]; then
echo "Warning: target_home '$target_home' does not exist, falling back to \$HOME: $HOME" >&2
target_home="$HOME"
elif [ -d "/home/${target_user}" ]; then
echo "Warning: target_home '$target_home' does not exist, falling back to /home/${target_user}" >&2
target_home="/home/${target_user}"
else
echo "Error: No suitable home directory found for '${target_user}'. Tried:" >&2
echo " - _REMOTE_USER_HOME='${_REMOTE_USER_HOME:-}'" >&2
echo " - \$HOME='${HOME:-}'" >&2
echo " - /home/${target_user}" >&2
echo "Please set _REMOTE_USER_HOME to a valid, writable directory." >&2
exit 1
