# Guardrails

> Deterministic policies that keep an agent on-script and verify callers before disclosure.

**Guardrails** are the deterministic rules that constrain what an agent will say and do — the
difference between "usually behaves" and "provably won't cross a line." Unlike the agent's
prompt, guardrails are enforced, not suggested.

## What guardrails cover

* **Topic and policy limits** — things the agent must refuse or redirect.
* **Caller verification** — require identity verification *before* disclosing sensitive
  information, so the agent never reads back an account detail to an unverified caller.
* **Escalation rules** — when to hand off to a human.
