One thing that sort of worked for me is to write the skeleton myself, i.e. the general ideas and how they fit together, the overall “flow” of what I want to say, then have an LLM fill in the blanks (I either point it at some context.md or have it ask me questions when details are missing). It’s kind of like designing the high level software architecture yourself and have the LLM write the code for each component. Not bulletproof, requires some iteration, but miles better than what it would produce on its own.
