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.
