I tend to feel like, I start out with a rough idea of a program I want to write in my head. I find it easier to just write the code directly than to write a document with sufficient detail about how I want it to work for an LLM to actually write the right code, then have the LLM write the code. And the resulting documentation is about as likely to be useless or a burden as it is to be helpful in the future.

You don’t write the doc. You talk to the LLM about the idea and the anchor points, and have it write the doc.
