Guardrail
A named prompt fragment. Every guardrail attached to a scenario is appended to that scenario's system prompt as a bullet under a `## Guardrails` heading, so the persona treats it as a non-negotiable rule for the whole conversation.
Properties
| Name | Type | Description |
|---|---|---|
| id | string | |
| membership_id | string | |
| guardrail_name | string | Handle for the rule. Unique per account. Used in the API and in your logs — it is never shown to the persona or the participant. |
| guardrail_prompt | string | The rule itself, appended verbatim to the system prompt. Write it as a direct instruction. Encrypted at rest. |
| active | boolean | Account-level kill-switch. `false` removes the rule from every scenario at once. |
| scenarios | array | Scenarios this guardrail is attached to. Returned only on the single-guardrail read. |
| created_at | string | |
| updated_at | string |
