It's software development, but with much less actual programming (in my case none).

When I said I check the documents, the initial design document was the only I really took a hard look at. The intermediary I just skimmed, looking for red flags or something I had forgotten to tell them. Those documents served as a basis for their work, and as a record of what was done.

Overall I spent perhaps a few hours on each project, over the course of a few days. I'd check in every half hour or whenever I had time, tell Claude "Great, let's do the next deliverable", or GPT "We're done with phase 4, please do a detailed code review, reference the design document and documentation of previous phases". Then I'd leave them cooking.
