To generate a custom Lightning type JSON schema, define a root object with required Lightning metadata, use primitive lightning__* types, and reference nested objects via the c__<CLTName> pattern for valid Einstein Agent structured inputs.

Custom Lightning type schema deployment validation fails when forbidden keywords like examples are present, required root fields are missing, or disallowed array patterns and incorrect lightning:type usage violate the strict metaschema constraints.

Yes, you can define a custom Lightning type schema using Apex class-based shape definitions by applying the @apexClassType annotation pattern to map your Apex structures directly into the Lightning Platform typed schema.

You can configure editor and renderer overrides for a Lightning custom type by applying safe, supported componentOverride layouts within editor.json and renderer.json files to render custom UI components for your structured inputs.

The correct pattern for referencing nested objects in a Lightning schema is using the c__<CLTName> reference format, which allows you to define reusable typed object structures across multiple Einstein Agent action inputs and outputs.

Yes, Einstein Agent actions require custom Lightning type JSON schemas to reliably ingest and output typed data, ensuring structured editor and renderer experiences validate correctly against strict Lightning Platform metaschema constraints.
