It's not fully documented, there are some bits of information here [www.sidefx.com]

You could also inspect the relevant handle with the Operator Type Handle Bindings panel along with the Parameter editor. The bindings panel list all handle with their parameters. The transformer node can be inspected in the Parameter editor to see the related parameters.

Can you post the code used for extracting the handle values ?

The custom file path option for saving recipes seems absolutely broken. I tried saving a recipe to a network location (i.e. "//something/goes/here/recipe.hda") and for some scuffed reason it appended "C:\User\username" to the front. When I try manually type the location I cannot delete the "C:\" part without it automatically refilling "C:\User\username" again so I can never fully clear the field. What on earth is up with that? Such incredibly frustrating design.

What is the intended design here? I just want to save a recipe to a common location (i.e. with HOUDINI_PATH or HOUDINI_OTLSCAN_PATH) so other artists can use them.

This is an obvious bug, the fix should be available in the next production build.
