Full safety mode: destructive command warnings + directory-scoped edits. (gstack).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- AUTO-GENERATED from SKILL.md.tmpl — do not edit directly -->
<!-- Regenerate: bun run gen:skill-docs -->
## 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
```
## Setup
Ask the user which directory to restrict edits to. Use AskUserQuestion:

How to install
mdr add tonydzi/second-brain-starter-kit/guard@sha256:ae1ec65c42568c76The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
