I toyed around with the idea of using an LLM to "compile" user instructions into a kind of AST of scaffolding, which can then be run by another LLM. It worked fairly wellbfor the kind of semi-structured tasks LLMs choke on like "for each of 100 things, do...", but I haven't taken it beyond a minimal impl.

I am working on something similar but with an AST for legal documents. So far, it seems promising but still rudimentary.
