assets.typeBehavior

What an asset of this TYPE can do: the operations every ref of it answers to (ref:method(...)), the lifecycle hooks it runs, and whether it can become an entity in a scene.

Knowing a type exists is not the same as knowing what it gives you. A type that already evaluates, instantiates, validates and recompiles itself is scaffolding to build inside. This is how you see that before deciding to write your own.

Pairs with assets.typeDoc for the prose; assets.installedTypes lists the installed types.
