careful

name: careful version: 0.1.0 description: | Safety guardrails for destructive commands. Warns before rm -rf, DROP TABLE, force-push, git reset --hard, kubectl delete, and similar destructive operations. User can override each warning. Use when touching prod, debugging live systems, or working in a shared environment. Use when asked to "be careful", "safety mode", "prod mode", or "careful mode". (gstack) triggers:

• be careful
• warn before destructive
• safety mode allowed-tools:
• Bash
• Read hooks: PreToolUse:
  • matcher: "Bash" hooks:
    • type: command command: "bash ${CLAUDE_SKILL_DIR}/bin/check-careful.sh" statusMessage: "Checking for destructive commands..."

/careful — Destructive Command Guardrails

Safety mode is now active. Every bash command will be checked for destructive patterns before running. If a destructive command is detected, you'll be warned and can choose to proceed or cancel.

mkdir -p ~/.gstack/analytics
echo '{"skill":"careful","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","repo":"'$(basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || echo "unknown")'"}'  >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true

How it works

The hook reads the command from the tool input JSON, checks it against the patterns above, and returns

permissionDecision: "ask"

To deactivate, end the conversation or start a new one. Hooks are session-scoped.
