Preview Custom Lightning Types in Agentforce Service Agents

Now you can validate your Agentforce Service agent’s custom responses in Agentforce Builder. Custom Lightning types (CLTs) are used to customize the UI for agent action inputs and outputs for a more branded, interactive experience. When you preview a conversation with a Service agent connected to Enhanced Chat v2, CLTs in agent actions render as your customers see them.

Note Preview for CLTs is currently supported only for actions added from the asset library. To preview CLTs for actions created or customized in Agentforce Builder, recreate the actions in the asset library, and then add them to your agent.

Where: This change applies to Lightning Experience in Enterprise, Performance, Unlimited, and Developer Editions with Foundations or Agentforce 1 Editions. Setup for AI agents is available on the desktop site.

When: This change is available starting the week of July 13, 2026.

How: To preview CLTs in an Agentforce Service agent, add the Enhanced Chat v2 connection to your agent. Then start a preview conversation in live test mode. Your agent version can be draft or committed.
