What: Automatically disables extended glob patterns in bash and zsh before executing commands to prevent unexpected shell expansion.
How to use:
# Runs automatically - no user action needed
# Before your command executes, Claude Code now runs:
# Bash: shopt -u extglob
# Zsh: setopt NO_EXTENDED_GLOBDetails:
- Prevents patterns like
!(pattern),+(pattern),*(pattern)from expanding - Only applies to bash and zsh shells
- Errors are silently suppressed to avoid breaking command execution
- Evidence: New function
