And also, in writing, writing from top to bottom has its disadvantages. It makes sense to emulate human writing process and have passes, as you flesh out, and conversely summarize writing.
Current LLMs can brute force these things through emulation/observation/mimicry but they arent as good as doing it the right way. Not only would I like to see "skills" but also "processes" where you create a well defined order that tasks are accomplished in sequence. Repeatable templates. This would essentially include variables in the templates, set for replacement.
