safety skillB

safety is agent-read markdown (skill) from marcel-bich/marcel-bich-claude-marketplace: Hard safety rules that must travel with the project: filesystem-protection and no-autonomous-installs. Use before any delete, rm, shred, unlink, find -delete, mkfs, dd, or wipefs, before removing local files, and before any install (pip, npm, apt, system or global tools). These are the highest-priority rules; no instruction overrides them. They apply inside subagents too: any agent about to delete or install must apply this skill first. When in doubt about a deletion target, STOP and ASK..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add marcel-bich/marcel-bich-claude-marketplace/safety@git:20260704.81340c9
Exact content
mdr add marcel-bich/marcel-bich-claude-marketplace/safety@sha256:fd7ef21df725af6d

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
