Good call. I’ve also had better results pre-processing PDFs, extracting data into structured format, and then running prompts against that.

Which should pair well with the “write a script” tactic.

Yeah, asking for a tool to do a thing is almost always better than asking for the thing directly, I find. LLMs are kind of not there in terms of always being correct with large batches of data. And when you ask for a script, you can actually verify what's going on in there, without taking leaps of faith.
