Shell Script Input Validation

This skill provides a standardized pattern for securing shell scripts that accept user input, such as task descriptions or file paths. It implements specific validation checks to detect and reject dangerous patterns including newline injection, command substitution (backticks and $() syntax), and variable expansion (${}). By integrating these checks early in the script execution flow, developers can prevent malicious strings from being executed in subshells or external programs, ensuring robust security for automated environments and multi-user scripts.
