The Cost Position System in Conlang?

The cost position system distinguishes agents and patients. These, uh, cost positions can be derived on the fly by combining one of the basic space time positions with a root word for some particular concepts. I'm adding more notes about that to the Mexican, um, more, uh, tested word that the definition of a verb will give to a large instructor for it. Um, another thing that I like for any conlang to be documented is you have a separate page on semantics for particular semantic fields which is great.
