What it does for you

A firewall for your agent's dangerous commands

A coding agent can fire off rm -rf or a force push in a second. This hook analyses every Bash command before it runs, sees through syntax tricks, blocks the serious cases and asks for your confirmation on the doubtful ones.

  • Block rm -rf ~, curl | sh and force-pushes to main
  • Stay in control: confirm sudo and reset --hard first
  • Let echo and grep through without false alarms
