What is PromptShield

A **methodology collection** for agent runtime safety — the same shape as the top-of-ecosystem superpowers collections: one repo, one `SKILL.md` orchestrator, multi-vendor plugin shims, and a one-page ASCII lifecycle map. Where external collections ship *tools without governance*, PromptShield ships **theory (LGD three laws) + skills + evidence chain + admission gates** as one auditable unit.
