block-dangerous-commands

v1.0.0

A PreToolUse guard for Bash that blocks dangerous shell commands before they execute: rm targeting home/root/system dirs, dd to disk devices, mkfs, fork bombs, curl|sh, force push to main, git reset --hard, chmod 777, docker volume rm, and more. Three safety levels (critical/high/strict, picked via HOOK_SAFETY_LEVEL) control how much is blocked, and per-level ask mode (HOOK_ASK_*) turns a hard deny into a prompt you approve or reject. Every block is logged with the pattern id and reason.
