# Global node

> Apply one shared persona, tone, or safety rule to selected prompted nodes without duplicating the text in every prompt.

Apply one shared persona, tone, or safety rule to selected prompted nodes without duplicating the text in every prompt.

## Prerequisites

* A workflow with at least one prompted node.
* Shared guidance that should remain consistent across the conversation.

## Apply shared guidance

1. Add one **Global** node to the workflow.
2. Write the shared prompt in short, speakable sentences.
3. Open each Agent or End Call node that should inherit it.
4. Enable **Add global prompt** on those nodes.
5. Test an inherited node and one node that deliberately does not use the global prompt.

## Constraints and failure states

Only one Global node is allowed per workflow, and it is not connected by edges. The prompt is applied only where **Add global prompt** is enabled; it does not automatically affect every node.

## Protect your data

Keep global guidance generic. Never put a shared credential, private endpoint, or tenant-specific record in a prompt that can be inherited widely.
