Safety Rules
Cross-cutting safety guardrail skill for Codex. Use when work could be destructive, expose secrets, touch shared modules, rewrite history, investigate failures under freeze, or change protected branches; triggers include "조심해서", safety, protection, secrets, rollback risk, and main-branch work. Prefer the task-specific mstack skill for planning, review, QA, shipping, or investigation after the safety posture is set.
