PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Remove redundant boolean flag value The --delete-session-on-ui flag is a boolean option that doesn't require a value. Passing "true" as a separate argument may cause parsing issues or unexpected behavior. NodeBase/start-selenium-node.sh [76-78] if [ "$SE_NODE_DELETE_SESSION_ON_UI" = "true" ]; then - append_se_opts "--delete-session-on-ui" "true" + append_se_opts "--delete-session-on-ui" fi Apply / Chat Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies that --delete-session-on-ui is a boolean flag and passing an extra "true" argument could cause command-line parsing issues, thus fixing a potential bug.
