Core insight: prompts are policy when they influence outcomes; left unmanaged they drift, replicate bias, and create hidden failure modes. This episode gives a compact, executive-grade Prompt Registry you can stand up in under an hour: a one‑page catalog of the 5–10 prompts that matter, each with owner, intent, success signals, rollback rule, and version history. Supporting moves: (1) how to pick which prompts qualify as high-impact; (2) a minimal versioning and owner model so changes are deliberate; (3) three lightweight audit checks—sample outputs, provenance, and a simple metric—that surface drift. You’ll get exact fields for the registry, a 10‑minute audit script, and a single action: register one prompt that currently touches revenue, hiring, or legal risk. The result: predictable AI behavior, less silent risk, and clearer accountability without red tape. Stay agentic.
