Developer creates safety hook to prevent Claude Code from destructive commands

By PulseAugur Editorial · [1 sources] ·

A developer has created a 15-line Python script designed to act as a safety hook for Claude Code, a coding agent. This hook, named PreToolUse, intercepts potentially destructive commands before they are executed by the agent. It specifically targets patterns like `rm -rf`, `git push --force`, infrastructure destruction commands (`terraform destroy`, `pulumi destroy`), and sensitive file access, prompting the agent for confirmation or a dry-run to prevent accidental data loss or system damage. AI

IMPACT Enhances safety for AI coding assistants by preventing accidental destructive actions, encouraging more cautious agent behavior.
