Developed a PreToolUse hook for the anthropics/claude-code repository, focusing on enhancing command-line workflow safety and performance. The solution consisted of a Python script that validated Bash commands by parsing JSON input, verifying tool context, and applying regular expression-based rules to detect non-compliant usage. To optimize performance, the script replaced traditional 'grep' calls with 'rg' and suggested safer alternatives for commands like 'find -name'. This approach improved reliability and enforced safety standards for Bash tool usage, while establishing a robust foundation for future enhancements. The work demonstrated proficiency in scripting, command-line tool integration, and advanced input validation techniques.
