# Guardrails & Prompts

> Input/output safety policies and a versioned prompt registry.

## Guardrails

Guardrails are safety policies checked against agent input and output.

* **kind**: `pii`, `regex`, `keyword`, `max_length`, or `json_schema`
* **target**: `input`, `output`, or `both`
* **action**: `block`, `redact`, or `warn`

```bash theme={null}
cruqai guardrails apply block-pii --kind pii --target output --action redact
cruqai guardrails list
```

## Prompts

A versioned registry of prompt templates. Templates use `{{variable}}`
placeholders; every edit bumps the version so callers can pin a revision.

```bash theme={null}
cruqai prompts apply support-triage \
  --template "You are a support agent. Answer: {{question}}"
cruqai prompts list
```
