Custom Lightning Types are defined as JSON Schema-based objects that describe structured inputs and outputs for Einstein Agent actions. You create a root object constrained by type: object, title, lightning__objectType, and unevaluatedProperties false to enforce data contracts.

Custom Lightning Types must enforce root object constraints including type: object, a title, lightning:type set to lightning__objectType, and unevaluatedProperties false. The metaschema rules also govern lists, nested objects, and allowed primitive types within the schema.

You apply Custom Lightning Type schemas to editor and renderer configurations to drive custom UI component behavior on the Lightning Platform. This involves wiring the CLT schema definitions to the specific editor and renderer configs for your interface.

Yes, Custom Lightning Type definitions support Apex-class-driven definitions. This allows developers to define structured inputs and outputs using Apex classes as the basis for the JSON Schema objects.

Custom Lightning Type deployment failures often stem from violating metaschema rules, such as missing root object constraints like unevaluatedProperties false or incorrect lightning:type settings. Troubleshooting involves validating schema structure against required constraints.

You need a Custom Lightning Type when creating structured inputs and outputs for Lightning Platform and Einstein Agent actions that require precise data contracts and specific UI behavior through editor and renderer configurations.
