  instructing an agent to write anything from scratch inevitably takes more time than writing it yourself

But you can reuse your instructions with zero additional effort. I have some instructions that I wrote for a 'Project' in Claude (and now a 'Gem' in Gemini). The instructions give writing guidelines for a children's article about a topic. So I just write 'write an article about cross-pollination' and a minute later I have an article I can hand to my son.

Even if I had the subject matter knowledge, it would take me much longer to write an article with the type of style and examples that I want.

(Because you said 'from scratch', I deliberately didn't choose an example that used web search or tools.)
