| description | Full safety mode: destructive command warnings + directory-scoped edits.
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).
mkdir -p ~/.gstack/analytics
echo '{"skill":"guard","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","repo":"'$(basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || echo "unknown")'"}' >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true
Setup
Ask the user which directory to restrict edits to. Use AskUserQuestion:
- Question: "Guard mode: which directory should edits be restricted to? Destructive command warnings are always on. Files outside the chosen path will be blocked from editing."
- Text input (not multiple choice) — the user types a path.
Once the user provides a directory path:
- Resolve it to an absolute path:
FREEZE_DIR=$(cd "<user-provided-path>" 2>/dev/null && pwd)
echo "$FREEZE_DIR"
- Ensure trailing slash and save to the freeze state file:
FREEZE_DIR="${FREEZE_DIR%/}/"
STATE_DIR="${CLAUDE_PLUGIN_DATA:-$HOME/.gstack}"
mkdir -p "$STATE_DIR"
echo "$FREEZE_DIR" > "$STATE_DIR/freeze-dir.txt"
echo "Freeze boundary set: $FREEZE_DIR"
Tell the user:
- "Guard mode active. Two protections are now running:"
- "1. Destructive command warnings — rm -rf, DROP TABLE, force-push, etc. will warn before executing (you can override)"
- "2. Edit boundary — file edits restricted to
<path>/. Edits outside this directory are blocked."
- "To remove the edit boundary, run
/unfreeze. To deactivate everything, end the session."
What's protected
See /careful for the full list of destructive command patterns and safe exceptions.
See /freeze for how edit boundary enforcement works.
