Command Guard

Category: General · Sub-category: general-misc · Last updated: 2026-05-21

Set up a PreToolUse hook in .claude/settings.json that blocks dangerous commands — rm -rf, force push, database drops, and others — before they execute. Teaches the pattern of safety hooks for any Claude Code project. Trigger words: safety, guard, block dangerous, protect, prevent destructive, safe mode, dangerous commands, risky operations.

From the source SKILL.md

Claude Code runs shell commands, edits files, and manages infrastructure with real consequences. Without guardrails, a misunderstood instruction or a hallucinated flag can delete data, corrupt history, or expose credentials. This skill installs a PreToolUse hook that blocks the most dangerous operations before they run.
