## When to invoke this skill

Combines /careful (warns before rm -rf, DROP TABLE, force-push, etc.) with
/freeze (blocks edits outside a specified directory). Use for maximum safety
when touching prod or debugging live systems. Use when asked to "guard mode",
"full safety", "lock it down", or "maximum safety".

# /guard — Full Safety Mode

Activates both destructive command warnings and directory-scoped edit restrictions.
This is the combination of `/careful` + `/freeze` in a single command.

**Dependency note:** This skill references hook scripts from the sibling `/careful`
and `/freeze` skill directories. Both must be installed (they are installed together
by the gstack setup script).

```bash
mkdir -p ~/.gstack/analytics
echo '{"skill":"guard","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
```

Ask the user which directory to restrict edits to. Use AskUserQuestion:
