Security and safety (conservative), backup management, temporary file management, firewall management. Use for backup confidence reports, isolated recovery exercises, destructive ops, system config changes, backups, temp files, or when adding services.
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
# Safety, Backup, Temp Files, Firewall
Use this skill as an instruction-only safety gate for destructive operations,
system configuration changes, backups, temporary files, and service exposure.
It does not ship shell helpers. When automation is added, implement it as
Python framework tooling that follows `ls/docs/TOOLING_POLICY.md` and
`ls/docs/INPUT_HARDENING_STANDARD.md`.
## Safety Gate
- **Default posture:** Favor data safety, least privilege, and reversible
changes over convenience.
- **Classify risk before acting:**
- **CRITICAL:** Data loss, disk operations, credential exposure, user/group
deletion, broad permission changes, recursive deletion, or changes under
`/usr`, `/etc`, `/bin`, `/sbin`, or comparable system paths.
- **HIGH:** Firewall changes, system service changes, package removal,
privileged installation, or changes that affect every user on the host.
- **MEDIUM:** Application-level changes, repo-local generated state, or
service restarts with limited blast radius.
- **LOW:** Read-only inspection and clearly reversible local edits.
- **Confirm CRITICAL/HIGH work:** State the exact command or edit, likely

How to install
mdr add cruxexperts/localsetup/ls-system-changes-backup@sha256:96ec1ecc9df83bfeThe line at the top of this page pins the label v1.2, 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.
