Platform Custom Lightning Type Generate

If you're building Einstein Agent actions or custom UI for Lightning Platform and need to work with Custom Lightning Types, this handles the entire workflow. It knows the counterintuitive rules that will break deployment: no $schema field allowed, arrays can't use items, nested objects need the referenced CLT pattern instead of inline definitions. The metaschema is strict and the error messages are cryptic, so having the primitive type constraints, editor component patterns, and Apex class reference syntax in one place saves hours of trial and error. It also covers widget renditions if you need custom LWC editors or renderers with the correct attribute binding syntax.
