> The point is writing that prompt takes longer than writing the code.

Luckily we can reuse system prompts :) Mine usually contains something like https://gist.github.com/victorb/1fe62fe7b80a64fc5b446f82d313... + project-specific instructions, which is reused across sessions.

Currently, it does not take the same amount of time to prompt as if I was to write the code.

Have to disagree with this too - ask an LLM to architect a project, or propose a cleaner solution and usually does a good job.

Where it still sucks is doing both at once. Thus the shift to integrating "to do" lists in Cursor. My flow has shifted to "design this feature" then "continue to implement" 10 times in a row with code review between each step.
