This is an interesting read and it’s close to my experience that a simpler prompt with less or no details but with relevant context works well most of the time. More recently, I’ve flipped the process upside down by starting with a brief specfile, that is markdown file, with context, goal and usage example I.e how the api or CLI should be used in the end. See this post for details:

In terms of optimizing code, I’m not sure if there is a silver bullet. I mean when I optimize Rust code with Windsurf & Claude, it takes multiple benchmark runs and at least a few regressions if you were to leave Claude on its own. However, if you have a good hunch and write it as an idea to explore, Claude usually nails it given the idea wasn’t too crazy. That said, more iterations usually lead to faster and better code although there is no substitute to guiding the LLM. At least not yet.
