[Question] Algorithmic formalization of FDT?

I occasionally see a question like “what would FDT recommend in ….?” and I am puzzled that there is no formal algorithm to answer it. Instead humans ask other humans, and the answers are often different and subject to interpretation. This is rather disconcerting. For comparison, you don’t ask a human what, say, a chessbot would do in a certain situation, you just run the bot. Similarly, it would be nice to have an “FDTbot” one can feed a decision theory problem to. Does something like that exist? If not, what are the obstacles?
